f2a88059e7 tools/nxstyle.c: Add missing zlib function names to white list 
The zlib compression functions are used in network utilities
for compression/decompression. These functions need to be added to
the nxstyle white list to prevent style checking errors since they
follow the zlib naming convention rather than NuttX's style guide.

Specifically, these functions are used in:
- apps/netutils/telnetc/telnetc.c for compressed data handling

575c608be8 drivers/usbdev/cdcacm.c: Fix a crash in cdcacm if usbdev gets unregistered while client calls close for the tty 
Make sure that the cdcacm is disconnected before the usbdev gets unregistered.

Also, check if the device is connected or not in cdcuart_txempty (uart_txempty). Otherwise there may be a crash during uart_tcdrain, called in tty close path, if the usbdev unregistration happens during the loop.

This issue can be triggered by monitoring the cable connection status in one thread, sending BOARDIOC_USBDEV_DISCONNECT if the usb cable is detached. In another thread close the ttyACM.

6dbdfb3cd5 arch/arm: Add LLVM configuration to CMake 
Added LLVM-specific configuration variables to ARM architecture CMake files:
- LLVM_ARCHTYPE for architecture variant (thumbv6m, thumbv7a, etc)
- LLVM_CPUTYPE for CPU target (cortex-m0, cortex-a5, etc)
- LLVM_ABITYPE for ABI (eabi/eabihf)

These changes enable LLVM/Clang toolchain support while maintaining
compatibility with existing GCC configurations. The LLVM variables
are set based on the same architecture/CPU/FPU configurations used
for GCC flags.

- Simplify CPU type detection logic while maintaining same functionality
- Use more consistent string variable naming convention

This change makes the CPU type detection more flexible and maintainable

Use findstring instead of direct equality checks for LLVM_CPUTYPE
conditions to better handle ARCHCPUEXTFLAGS that may contain additional
ISA extensions. This makes the CPU type detection more robust when
dealing with extended instruction sets while still ensuring the required
base ISA extensions are present.

For example, ARCHCPUEXTFLAGS="imc_zicsr_zifencei" will now correctly
match as sifive-e20 rather than failing the exact match check.

4bd2c0443b Preliminary add of fdcan source files.
Some checks are pending
Build Documentation / build-html (push) Waiting to run
Details 
Adding source files to the fdcan branch based on identical register set. These files should mostly just work.

Removed references to FDCAN3. H5 only has 2 FDCAN interfaces.

Add basic FDCAN Kconfig

FDCAN Kconfig options

Added various options for FDCAN mode, FDCAN bitrate, clock selection and division, and timing.

Added bit timing config options (nominal and data). Added stm32h56xxx pin mappings.

Fixed Data Bit Timing. Pulled in STM32H5_FDCAN_PDIV_VALUE. Added stm32_fdcan.c to Make.defs. Added DBITRATE to Kconfig

Clock source changes to FDCAN

Moved the setting of the clock source to the stm32h5xx_rcc.c file. Added notes to stm32_fdcan.c that STM32_FDCAN_FREQUENCY and STM32_FDCAN_PDIV should be set in board.h

Change STM32H5_FDCAN_PDIV to STM32_FDCAN_PDIV

Updated Kconfig to match G4 implementation. Removed stm32_fdcan_sock for now.

Removed FDCAN3 from stm32_fdcan.h

incomplete changes for bit timning

Set NBRP and DBRP registers based on STM32H7 FDCAN socket algorithm.

Added board file for initializing 1 can device. Will update later to initialize second device.

Fixed ifdefs. Changed STM32 to STM32H5.

Add some can testing changes.

Added option to configure bit timing, with automatic bit timing set as default.

Style fixes

Fixed FDCAN2 and memory access issues

FDCAN2 msgram offset was wrong by 1 word (4 bytes). I removed the + 4 at the end of the definition. This fixed the issues with fdcan2. Also changed ifdefs when setting ESI, FDF, and BRS bits. When CAN FD was used, this resulted in the first command after the endif (the setting of dest at line 2325) being skipped because it was included in the else block when it shouldn't have. This resulted in exceptions. Adjust ifdefs fixes this problem. Other minor fixes.

Restoring board files to upstream versions. These files will be pulled in later in a separate pull request. stm32h5_fdcan_test branch created for this.

Fixed Queue Mode Transmit

The can driver checks the TFFL bits in the TXFQS register. In Queue mode, this always returns 0. As a result, fdcan_txempty was always returning false, which resulted in no transmissions. This code fixes that.

Add stm32h5 fdcan chardriver to Make.defs

6b1be7c66c virtio-rng: Register /dev/urandom driver if CONFIG_DEV_URANDOM=y 
Virtio RNG support (CONFIG_DRIVERS_VIRTIO_RNG=y) selects
CONFIG_ARCH_HAVE_RNG. On the other hand, if CONFIG_DEV_URANDOM=y,
it defaults to CONFIG_DEV_URANDOM_ARCH if CONFIG_ARCH_HAVE_RNG=y.
DEV_URANDOM_ARCH definition states that the implementation of the
/dev/urandom should be provided by the architecture-specifig logic,
including the function devurandom_register(). In this case, the
/dev/urandom may refer to the same driver as /dev/random that is
provided by the Virtio RNG driver, which is implemented by this
commit.

2. UDP uses `iob_navail(false)` but TCP uses `iob_navail(true)`, this is because of a problem related to TCP recv window (https://github.com/apache/nuttx/pull/4142), so we don't need to change UDP now.

1cfab89e65 Added incomplete octospi hardware defintions.
Some checks failed
Build Documentation / build-html (push) Has been cancelled
Details 
Register addresses are defined. Bit defintions are still needed.

Bitmaps for OCTOSPI peripheral register

Incremental updates to qspi files

Redefined QSPI/OCTOSPI registers for STM32H5

Fixed register definitions for the STM32H5. However, more work still needs to be done. Some bits that shared registers on the STM32H7 have different register locations on the H5. This still needs to be accounted for.

Fixed more differences vs STM32H7 qspi

Added ifdef for including stm32_dma.h in stm32_qspi.c. Added stm32_qspi.c to Make.defs.

Register fixes. SPI activity but not able to format device yet.

Fixed DCYC mask

Set HCLK frequency to correct value. Undid ccrconfig debug.

Tested Interrupt Mode (single SPI). Added alternate bytes to meminfo and cmdinfo structures. Updated Kconfig variables for STM32H5.

Fixed base register in hardware/stm32_qspi.h. Updated qspi_dumpregs.

The base register was previously set to STM32_QUADSPI_BASE, changed to the correctly named STM32_OCTOSPI1_BASE. However, these defines for the OCTOSPI registers are not even used. Instead qspi_putreg and qspi_getreg utilize the priv->base value to access OCTOSPI registers.

Removed altbytes code, left as before. Moved QSPI clock selection to stm32h5xx_rcc.c

Changed STM32H5_QUADSPI to STM32H5_QSPI1

Added hook to define QSPI_CLK_FREQUENCY as STM32_QSPI_FREQUENCY from board.h

Removed changes to nuttx qspi.h

96fa400c3d Fixed errors in CI build tests for pull request #15351 
There were two simple errors when running ci tests on pull #15351. These errors were unrelated to that pull. After investigating I found two simple errors. 1. The len variable was likely a typo that should have been the function argument, ien. 2. The spinlock_t lock was defined in a section dependent on CONFIG_SERIAL_TERMIOS. However, the spinlock_t lock was used in code that did not require the SERIAL_TERMIOS config. Therefore errors resulted.

imxrt_edma_s missing lock variable

CI build tests noted that the variable g_edma was referencing a lock variable that did not exist in the structure. This change adds that missing lock as a spinlock_t type.

Remove unused flags variable from imxrt_dmach_stop

2886fddc0f arm64: fix tpidr maybe null 
Before the MPU initialization, the up_update_task(this_cpu()) function is called at a time when hardware cache coherency is not yet enabled.
In certain critical scenarios, Core 1 reads a zero value for tcb from the global variable g_assignedtask and stores this zero value into the tpidr
register. This results in subsequent interrupt handlers reading a zero tcb, causing an exception.

1fe07d0838 net: Add buffer pool to replace connection allocation 
Our net socket connection allocations are powerful but redundant
because they're implemented once in each protocol.  This is not good for
further optimizing and extending to other allocations, so maybe we can
add a common implementation for the usage.

Impact:
1. We add a `struct net_bufpool_s` as pool descriptor, which may use a
   little bit more memory than previous implementation (~28Bytes).
2. We share same functions between pools, so code size may shrink under
   some scenarios.

badb5c5ac6 [POSIX][Bug] syslog: Add support for %m modifier 
The POSIX standard states that the `syslog()` function generates
the body from the message and arguments the same way as `printf()`,

> except that the additional conversion specification `%m` shall be
> recognized;

*https://pubs.opengroup.org/onlinepubs/009695399/functions/syslog.html*

What most of the implementations do is to leverage the processing to
`vsprintf` internals, to reduce code duplicity. This means the `%m`
modifier is present on almost all `printf` implementations. Take
the following code snippet as an example: https://onlinegdb.com/YdR9pU6KS.

Therefore, for `syslog` to support such a specification, the underlying
library shall be updated to support it too.

In libuv, if the real_timeout in the uv__io_poll is less than 0, the poll logic will be entered directly by the uv__run_timers, which will trigger the ASSERT.
It seems that the situation of first epoll and then poll for the same fd is used in libuv.

b3813bd450 gcov: Solve the problem of incorrect report generation caused by different compilation and test environments 
Due to the makefile, the relative paths of the files are different, and
it is impossible to use existing tools such as gcov and lcov to specify
a base compilation path for them.
The solution for Linux is to copy a copy of the source code from
the compilation environment to the test environment,
and there is a place that is consistent with the absolute
path of the compilation environment.
This solution is to pass in the "-b" parameter to directly
modify the info file generated by lcov. The search path will be
executed in the next step of genhtml

d59b8f25b8 Added hardware defines for stm32h5_qspi driver and octospi GPIOs (used by stm32h5_qspi driver). 
Fixed comments and indent

Add commit log to OCTOSPI HW PR

Summary

hardware/stm32_qspi.h - Defines for the STM32H5 QSPI driver. The peripheral on the STM32H5 is actually an OCTOSPI peripheral, however it was decided to use it as a QSPI peripheral for the following reasons:

    There is currently support for QSPI within Nuttx.
    The STM32H7 QSPI register set is very similar to the STM32H5 OCTOSPI register set and the STM32H7 series has an existing QSPI driver.
    OCTOSPI devices are rare as of now and are not part of our use case.

hardware/stm32h56xxx_pinmap.h - Added pin mappings for OCTOSPI GPIOs.
Impact

This change will not impact any architectures outside of the STM32H5 series. Even for the STM32H5 series, these changes will only have an impact if they are utilized.
Testing

No testing yet for these files other than ensuring that we can still build Nuttx. Further testing will be documented in a future pull request when the STM32H5 QSPI driver is added.

884b4604c2 Map user memory passed to accept() in kernel build 
Fixes an issue in kernel build where the user addresses passed
to accept() would be accessed when the wrong MMU mappings were
active. A crash would manifest when attempting to accept() on a
TCP server socket for instance under significant load. The accept
event handler would be called by the HP worker upon client
connection. At this point, accept_tcpsender() would attempt to
write to `addr` resulting in a page fault. Reproducibility would
depend on the current system load (num tasks or CPU stress) but
in loaded environments, it would crash almost 100% of the times.

It should be noted that Linux does this the other way around: it
operates on kernel stack allocated data and once done, it copies
them to user. This can also be a viable alternative, albeit with
one extra copy and a little extra memory.

ea020a4eae sem_holder.c: Replace addrenv_select with kmm_map for holder sem access 
The holder list can be modified via interrupt so using addrenv_select is
not safe. Access the semaphore by mapping it into kernel virtual memory
instead.

510d9659b4 sem_waitirq: Use kmap interface to access the semaphore 
The temporary mappings via addrenv_select() and addrenv_restore() simply
do not work from interrupt, so remove its usage and replace with kmap
which is safe.

95d1e52535 mm/kmap: Provide the user tcb as parameter to map_user() 
This allows mapping pages from others than the running task. Obiously
this can only be done with proper preparations (the task in question
cannot exit before the mapping is released).

e96fb6b118 arch/bcm2711, boards/raspberry-pi-4b: Add preliminary support for the BCM2711 and Raspberry Pi 4B. 
Includes a Mini-UART NSH console for the 4B, tested on the 4GB RAM
model. Part of an I2C driver which can only read, boiler-plate for a SPI
driver, and a GPIO driver with limited pins. Some tools are present for
automatically fetching the boot files and creating the `config.txt` file
based on selected Kconfig options.

define NuttX local NuttX-PublicDomain identifier

 “Public Domain” is a concept distinct from copyright licensing;
it generally means that the work no longer has any copyright protection
or ownership, and therefore requires no license permission in order to
use, copy, modify, distribute, perform, display, etc.
In the United States – and many jurisdictions – copyright protections
attach automatically to creative works upon creation if they satisfy
certain minimum criteria.
“Public Domain” would thus represent a significant change to the legal
status of the work.
The rules around “Public Domain” often vary or are unspecified
jurisdiction to jurisdiction. Adding to the confusion, some
jurisdictions may not even recognize the concept of “Public Domain”
(or similar). As such, a license may nevertheless be required or implied
in these cases. Even in the U.S., there is no clear,
officially-sanctioned procedure for affirmatively placing
copyright-eligible works into the “Public Domain” aside from natural
statutory expiration of copyright. The bottom-line is, there are few if
any objective, brightline rules for proactively placing
copyright-eligible works into the Public Domain that we can broadly
rely on.

b46edd1252 fs/reference_count: set default reference count option depends on DISABLE_PTHREAD 
Most of developers will not have the scenarios of open/close file descriptors in multi-threads,
The default option will incur additional code size overhead for such devices.
this PR will preserve the behavior before PR#13296 was introduced, and ensure that the default code size is not affected.

Note that this option will ensure the safety of access to the file
system from multi-tasks (Task A blocking rw(fd), then Task B close(fd)),
the disadvantage is that it will increase the amount of code-size,
there is no need to enable this option if the application could ensure
he file operations are safe.

fd3f0b7dd9 arch/risc-v/src/mpfs/mpfs_corespi.c: Add support for multiple bit widths 
The corespi fpga block supports just one frame length, which is defined when
the block is instantiated on the FPGA.

This adds support for emulating different frame lengths if they are multiples
of 8-bit. That is, with 8-bit corespi one can do 8,16 and 24-bit transfers.

This is implemented by simply writing several 8-bit frames for a single word
when needed.

d1786507b6 net/tcp_timer: fix tcp RTO abnormally large after retransmission occurs 
when tcp retransmission only double conn->timer in Karn(tcp_timer.c L602), after retransmission in Jacobson
M is is now rtt test will become a negative value.
```
  signed char m;
  m = conn->rto - conn->timer; // M is now rtt test

  /* This is taken directly from VJs original code in his paper */

  m = m - (conn->sa >> 3);
  conn->sa += m;              //conn->sa is a negative value
  if (m < 0)
	{
	  m = -m;
	}

  m = m - (conn->sv >> 2);
  conn->sv += m;
  conn->rto = (conn->sa >> 3) + conn->sv; //rto
```
For example,we lost one ack packet, we will set conn->timer = 6 by backoff，conn->rto still 3.
After retransmission we will Do RTT estimation, then will get
```
conn->sa = 253
conn->rto = 46
```
Then if any packets lost it will wait for a long time before triggering a retransmission.

Test method.
We can reproduce this issue by adding drop ACK packets in tcp_input, and debug conn->rto after Jacobson.

9b99493e14 Initial STM32H5 SPI Commit 
Used STM32H7 spi driver as a base. The register set is nearly identical. All registers are named the same with the same offset. There are some bits within the registers that are different but are not referenced in stm32_spi.c. Therfore this driver may just work as is. I did modify the clock source selection for each SPI peripheral, but not much else. Differences in the registers were applied in hardware/stm32h5xxx_spi.h.

Added functionality to SPI to configure the SPI RCC clock.

Added SPI info to Kconfig, updated stm32_spi.c to select and set the RCC clock, and other minor updates.

Updated Pin Map for SPI, added CFG1_BPASS support

Fixed redefinition of GPIO_SPI6_SCK_2

Added SPI_MAX_KER_CK definition.

This definition was needed because the H50 chips allow a kernel clock of 250 MHz. However the datasheets for all other chips (H52, H53, H56, H57) have a max of 125 MHz.

Changed SPI Clock Source Configuration

Moved setting of SPIx clock sources to stm32h5xx_rcc.c. STM32_SPIx_FREQUENCY and STM32_RCC_CCIPR3_SPIxSEL are now defined in board.h. Added error checking in stm32_spi.c to make sure STM32_SPIx_FREQUENCY and STM32_RCC_CCIPR3_SPIxSEL are actually defined.

Style updates

Removed SPI Clock selection from Kconfig

Update arch/arm/src/stm32h5/stm32_spi.h

L2 needs to be zeroed to make the ECC happy. However, if there's

d1772e1432 [POSIX][Bug] mqueue.h: Include file does not conform the standard 
The Open Group Base Specification IEEE Std 1003.1-2024 states that

> The <mqueue.h> header shall define O_RDONLY, O_WRONLY, O_RDWR,
> O_CREAT, O_EXCL, and O_NONBLOCK as described in <fcntl.h>.
https://pubs.opengroup.org/onlinepubs/9799919799/basedefs/mqueue.h.html

It also states that:

> The <mqueue.h> header shall define the struct timespec structure as described in <time.h>.
https://pubs.opengroup.org/onlinepubs/9799919799/basedefs/mqueue.h.html

The way the `mqueue.h` include file is defined right now violates the
standard, having potentially different code depending on the platform the
code is being compiled against - assuming a multi-arch POSIX environment.

The standard also states that:

> Inclusion of the <mqueue.h> header may make visible symbols defined
> in the headers <fcntl.h>, <signal.h>, and <time.h>.

So having those includes shouldn't be an issue.

0e1b432dd0 armv7/8m: fix regresion from https://github.com/apache/nuttx/pull/14881 
reason:
svc call may trigger hardfault

Background
    The origin of this issue is our desire to eliminate the function of storing
"regs" in g_current_regs and instead utilize (*running_task)->xcp.regs for storage.
The benefits of this approach include faster storage speed and
avoiding multiple accesses to g_current_regs during context switching,
thus ensuring that whether returning from an interrupt or an exception,
we consistently use this_task()->xcp.regs

Issue Encountered
    However, when storing registers, we must ensure that (running_task)->xcp.regs is invalid
so that it can be safely overwritten.
According to the existing logic, the only scenario where (running_task)->xcp.regs
is valid is during restore_context. We must accurately identify this scenario.
Initially, we used the condition (running_task)==NULL for this purpose, but we deemed
this approach unsatisfactory as it did not align well with the actual logic.
(running_task) should not be NULL. Consequently, we adopted other arch-specific methods for judgment,
but due to special logic in some arch, the judgment was not accurate, leading to this issue.

Solution:
    For armv6-m, we haven't found a more suitable solution, so we are sticking with (*running_task)==NULL.
    For armv7-m/armv8-m, by removing support for primask, we can achieve accurate judgment.

    PRIMASK is a design in armv6-m, that's why arm introduce BASEPRI from armv7-m.
It's wrong to provide this option for armv7-m/armv8-m arch.

``Python`` Python interpreter
=============================
This guide explains how to run Python on NuttX.
*Yes, you heard it right*. **Python on NuttX**. This is a port of the `CPython <https://github.com/python/cpython>`_ repository for NuttX.
The `CPython` repository is the reference implementation of the Python programming language.
It is written in C and is the most widely used Python interpreter.
.. warning::
Python for NuttX is still in the experimental stage (thus, it requires ``CONFIG_EXPERIMENTAL`` to be enabled)
It is not fully functional for all the architectures and configurations.
Please check this `issue <https://github.com/apache/nuttx-apps/issues/2884>`_ in the `nuttx-apps <https://github.com/apache/nuttx-apps/>`_ repository to know the current status.
How Does it Work?
=================
1. Python for NuttX target initially the ``rv-virt`` (RISC-V QEMU) board.
2. Python modules are stored in `pyc <https://docs.python.org/3/glossary.html#term-bytecode>`_ (byte-code format) and are loaded from a ROMFS image at startup.
3. Environment variables like ``PYTHONHOME`` and ``PYTHON_BASIC_REPL`` need to be set accordingly.
Building Python NuttX
=====================
Use the ``rv-virt:python`` config to build Python for NuttX. Note that the CMake scripts don't work for this configuration. For now, please use the makefile build instead:
.. code:: console
$ cd nuttx
$ make distclean
$ ./tools/configure.sh rv-virt:python
$ make -j$(nproc)
$ ls -l nuttx
This will generate a ``nutxx`` binary. This file can be run using the RISC-V QEMU.
Try Python in NSH
=================
Before running the RISC-V QEMU, create a raw disk image with the following command:
.. code:: console
$ dd if=/dev/zero of=./mydisk-1gb.img bs=1M count=1024
Then, run RISC-V QEMU with the following command:
.. code:: console

Building NuttX with Applications Outside the Source Tree
========================================================
.. warning::
Migrated from:
https://cwiki.apache.org/confluence/display/NUTTX/Building+NuttX+with+Applications+Outside+of+the+Source+Tree
Q: Has anyone come up with a tidy way to build NuttX with board-specific pieces outside the source tree?
========================================================================================================
A: Here are four approaches:
============================
1. Make export
--------------
There is a make target called ``make export``. It will build NuttX, then bundle
all of the header files, libraries, startup objects, and other build components
into a ``.zip`` file. You can move that ``.zip`` file into any build environment
you want. You can even build NuttX under a DOS CMD window.
This ``make target`` is documented in the top-level
:doc:`Legacy README </introduction/resources>`. Search for ``Build Targets``
1. Replace the apps/ Directory
------------------------------
You can replace the entire ``apps/`` directory. It is not a critical part of the
OS. The ``apps/`` is simply provided for you to help with your application
development. It should not dictate anything that you do.
To use a different ``apps`` directory, simply execute ``make menuconfig`` in the
top-level ``nuttx/`` directory and redefine ``CONFIG_APPS_DIR`` in your
``.config`` file so that it points to a different, custom application directory.
Note that ``CONFIG_APPS_DIR`` is a `relative` path from the top-level
``nuttx/`` directory.
You can copy any pieces that you like from the old ``apps/`` directory to your
custom ``apps`` directory as necessary. This is documented in
the `NuttX Porting Guide <https://cwiki.apache.org/confluence/display/NUTTX/Porting+Guide>`_
and in the `apps/README.md <https://github.com/apache/nuttx-apps/blob/master/README.md>`_ file.
1. Extend the apps/ Directory
-----------------------------
If you like the random collection of stuff in the ``apps/`` directory but just
want to expand the existing components with your own, external sub-directory,
then there is an easy way to do that too: Create a symbolic link in the
``apps/`` directory that redirects to your application sub-directory (or copy
your code into a sub-directory of ``apps/``).
.. image:: image/custom_app_dir_through_extension.png
Makefile and Make.defs
^^^^^^^^^^^^^^^^^^^^^^
In order to be incorporated into the build, the directory that you link under
the ``apps/`` directory should contain:
1. A ``Makefile`` that supports the ``clean`` and ``distclean`` targets (see
other Makefiles for examples).
2. A tiny ``Make.defs`` make file fragment that simply adds the build
directories to the variable ``CONFIGURED_APPS`` like:
.. code-block:: shell
CONFIGURED_APPS += my_directory1 my_directory2
Automatic Sub-directory Inclusion
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The ``apps/Makefile`` will always automatically check for the existence of
sub-directories containing a ``Makefile`` and a ``Make.defs`` file. The
``Makefile`` will be used only to support cleaning operations. The
``Make.defs`` file provides the set of relative paths to directories to be
built; these directories must also contain a ``Makefile``. That ``Makefile`` can
build the sources and add the object files to the ``apps/libapps.a`` archive
(see other Makefiles for examples). It should support the ``all``, ``install``,
``context``, and ``depend`` targets.
``apps/Makefile`` does not depend on any hard-coded lists of directories.
Instead, it does a wildcard search to find all appropriate directories. This
means that to install a new application, you simply have to copy the directory
(or link it) into the ``apps/`` directory. If the new directory includes a
``Makefile`` and a ``Make.defs`` file, then it will be automatically discovered
and included in the build at ``make`` time.
Kconfig
^^^^^^^
If the directory that you add also includes a ``Kconfig`` file, then it will be
automatically included in the NuttX configuration system as well.
``apps/Makefile`` uses a tool at ``apps/tools/mkkconfig.sh`` that dynamically
builds the ``apps/Kconfig`` file at pre-configuration time.
.. note::
The native Windows build will use a corresponding tool called
``apps/tools/mkconfig.bat``.
Install script
^^^^^^^^^^^^^^
You could, for example, create a script called ``install.sh`` that installs a
custom application, configuration, and board-specific directory:
1. Copy ``MyBoard`` directory to ``boards/MyBoard``.
2. Add a symbolic link to ``MyApplication`` at ``apps/external``
3. Configure NuttX:
.. code-block:: shell
tools/configure.sh MyBoard:MyConfiguration
Special ``apps/external`` Directory
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Use of the name ``apps/external`` is suggested because that name is included in
the ``.gitignore`` file and will save you some nuisance when working with GIT.
4. Contain the apps/ Directory
------------------------------
A simple, minimally invasive approach would be to contain the ``apps/`` GIT
clone within your custom application directory. In this case, ``apps/`` would
appear as a directory under your custom application directory instead of your
application directories being inserted as sub-directories of ``apps/``. It may
even be implemented as a sub-module of your custom application directory.
.. image:: image/custom_app_dir_through_containment.png
Kconfig and Makefile
^^^^^^^^^^^^^^^^^^^^
There are only a few minimal requirements of your custom application directory.
It needs to have only its own ``Makefile`` and ``Kconfig`` file. That
``Kconfig`` would need to include the ``apps/Kconfig``. The ``Makefile`` would
similarly need to invoke the ``apps/Makefile`` for all of the relevant build
targets. For example, the ``clean`` target:
.. code-block:: shell
$(MAKE) -c apps clean TOPDIR=$(TOPDIR)
Library Issues
^^^^^^^^^^^^^^
The contained directory will create and install a static library called
``libapps($LIBEXT)`` in the ``nuttx/staging`` directory. Your custom logic must
also appear in the ``nuttx/staging`` directory. Here are two ways that you might
do that:
1. **Merge with ``libapps($LIBEXT)``.**
The custom application directory's ``Makefile`` could create and install the
final ``libapps($LIBEXT)`` in the ``nuttx/staging`` directory.
``<custom-dir>/apps/libapps($LIBEXT)`` could merge its custom object files
with ``<custom-dir>/libapps($LIBEXT)`` and then re-install the library at
``nuttx/staging``.
2. **Use the EXTRA_LIBS Feature.**
The build system supports two special make-related variables called
``EXTRA_LIBS`` and ``EXTRA_LIBPATHS``. These may be defined in your
board-specific ``Make.defs`` file. ``EXTRA_LIBS`` provides the name of your
custom library. If you create ``<custom-dir>/libcustom.a``, then the value
of ``EXTRA_LIBS`` would be ``-lcustom`` and the value of ``EXTRA_LIBPATHS``
would be ``-L <custom-dir>`` (assuming the GNU ld linker).
Relative Effort and Benefits
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The contained ``apps/`` directory approach requires some more effort than the
extended ``apps/`` approach, but has the advantage that there will be no strange
behavior due to issues with ``.gitignore`` and, hence, a cleaner user
experience.
Out-of-tree Builds
^^^^^^^^^^^^^^^^^^
This configuration also has the possibility of supporting out-of-tree builds
using ``fusefs``. Suppose, for example, that you have a project directory with
the contained ``apps/`` directory and, say, three platform build directories.
Using ``fusefs``, you can overlay one of the platform build directories on top
of the project directory. Then all files generated by the build will be written
into the overlaid platform build directory. When the ``fusefs`` is torn down,
the project directory will still be clean, and the build result will still be in
the platform build directory. This can then be repeated for the other two
platform build directories.
In this case, you would probably also want to contain the ``nuttx/`` directory
in the project directory as well so that the entire system is built out-of-tree.
Hooking External Applications into the Configuration System
-----------------------------------------------------------
Suppose you have opted to extend the ``apps/`` directory with your custom
external application directories and would also like to support configuration
variables in your external application. No problem! Thanks to Sebastien Lorquet,
any external application that you install into the ``apps/`` (whether via a
symbolic link or via a directory copy) `will` be included in the NuttX
configuration system.
The top-level ``Kconfig`` file in the ``apps/`` directory is automatically
generated based on the contents of each ``apps/`` sub-directory. If your
installed sub-directory contains ``Kconfig``, ``Makefile``, and ``Make.defs``
files, then it will be incorporated into the NuttX configuration system when the
top-level ``Kconfig`` file is generated.

Building uClibc++
=================
.. warning::
Migrated from:
https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=139629550
and is probably outdated
A version of `uClibc++ <http://cxx.uclibc.org/>`_ has been ported to NuttX and is available in the NuttX
uClibc++ GIT repository at `Bitbucket.org <https://bitbucket.org/nuttx/uclibc/>`_ . This version of uClibc++ was
adapted for NuttX by the RGMP team.
This custom version of uClibc++ resides in the NuttX repository at:
https://bitbucket.org/nuttx/uclibc/
rather than in the main NuttX source tree, due to licensing issues: NuttX is
licensed under the permissive, modified BSD License; uClibc++, on the other
hand, is licensed under the stricter GNU LGPL Version 3 license.
General build instructions are available in the uClibc++ `README.txt <https://bitbucket.org/nuttx/uclibc/src/master/README.txt>`_
file. Those instructions are not repeated here. This page documents specific
issues encountered when building this NuttX version of uClibc++ and how they
are resolved.
Undefined Reference to ``_impure_ptr``
======================================
**Problem**
When building uClibc++, you may encounter an undefined reference to
``_impure_ptr`` similar to:
.. code-block:: none
LD: nuttx
.../arm-none-eabi/lib/armv7e-m\libsupc++.a(vterminate.o): In function
`__gnu_cxx::__verbose_terminate_handler()`:
vterminate.cc:(.text._ZN9__gnu_cxx27__verbose_terminate_handlerEv+0xfc):
undefined reference to `_impure_ptr'
**Solution**
A definitive, elegant solution is not known, but the following workaround has
proven to work:
1. Locate the directory where you can find ``libsupc++``:
.. code-block:: console
arm-none-eabi-gcc -mcpu=cortex-m4 -mthumb -print-file-name=libsupc++.a
2. Go to that directory and save a copy of ``vterminate.o`` (in case you need
it later):
.. code-block:: console
cd <the-directory-containing-libsupc++.a>
arm-none-eabi-ar.exe -x libsupc++.a vterminate.o
3. Remove ``vterminate.o`` from the library. At build time, the uClibc++
package will provide a usable replacement:
.. code-block:: console
arm-none-eabi-ar.exe -d libsupc++.a vterminate.o
4. At this point, NuttX should link with no problem. If you ever want to
restore the original ``vterminate.o`` to ``libsupc++.a``, you can do so
by running:
.. code-block:: console
arm-none-eabi-ar.exe rcs libsupc++.a vterminate.o
After removing ``vterminate.o`` from the standard library, the
uClibc++-provided ``vterminate.o`` becomes the active implementation and
prevents references to ``_impure_ptr`` from arising during linkage.
.. note::
Always exercise caution when modifying toolchain libraries. This
workaround is known to be effective but it replaces standard library
objects, which may have side effects in other toolchain usage scenarios.

Custom Application Directories
===========================================
.. warning::
Migrated from:
https://cwiki.apache.org/confluence/display/NUTTX/Custom+Application+Directories
Most people use the generic ``apps/`` directory with NuttX. That is convenient
and well-documented. However, it should always be remembered that NuttX is a
stand-alone, general-purpose OS and has **no dependency** on that "canned"
application directory.
This page shows how to create your own, custom application directory from
scratch.
Creating the Custom Application Directory
=========================================
Below is a simple example of the **minimum** custom application directory. It
contains only three files: ``Makefile``, ``Kconfig``, and ``hello.c``.
Makefile
--------
The custom application directory must include a ``Makefile`` that supports all
of the make targets expected by the NuttX build system **and** must generate an
archive called ``libapps.a`` in the top-level of the custom directory structure.
The minimal required targets for the ``Makefile`` look like this:
.. code-block:: shell
APPDIR = ${shell pwd}
-include $(TOPDIR)/Make.defs
# files
CSRCS = hello.c
COBJS = hello.o
ROOTDEPPATH = --dep-path .
# Build targets
all: libapps.a
.PHONY: dirlinks context preconfig depend clean clean_context distclean
.PRECIOUS: libapps$(LIBEXT)
# Compile C Files
$(COBJS): %$(OBJEXT): %.c
$(call COMPILE, $<, $@)
# Add object files to the apps archive
libapps.a: $(COBJS)
$(call ARCHIVE, libapps.a, $(COBJS))
# Create directory links
dirlinks:
# Setup any special pre-build context
context:
# Setup any special pre-configuration context
preconfig:
# Make the dependency file, Make.deps
depend: Makefile $(CSRCS)
$(Q) $(MKDEP) $(ROOTDEPPATH) "$(CC)" -- $(CFLAGS) -- $(SRCS) >Make.dep
# Clean the results of the last build
clean:
$(call CLEAN)
# Remove the build context and directory links
clean_context:
# Restore the directory to its original state
distclean: clean clean_context
$(call DELFILE, Make.dep)
# Include dependencies
-include Make.dep
Kconfig
-------
A ``Kconfig`` file must be included, but it need not contain any meaningful
configuration options. This file is where you can add application-specific
configuration settings if desired. The minimal ``Kconfig`` might look like:
.. code-block:: shell
# For a description of the syntax of this configuration file,
# see the file kconfig-language.txt in the NuttX tools repository.
#
hello.c
-------
Your custom application must compile at least one source file to generate the
required ``libapps.a`` archive. One of these source files must include the
``main()`` entry point to the application. That main function (or similarly
named entry point) is called after OS initialization completes.
What this application initialization entry point does, how it interacts with
the rest of your application, and where the rest of you application code is
located is of no concern to the OS. Only this one entry point is needed.
Below is a small "Hello, World!" example, where ``custom_main()`` is the
application entry point:
.. code-block:: c
#include <stdio.h>
int custom_main(int argc, char *argv[])
{
printf("Hello, World!!\n");
return 0;
}
Building with the Custom Application Directory
==============================================
In order to build with the new custom application directory, you need the
following in your NuttX configuration:
.. code-block:: shell
CONFIG_APPS_DIR="../custom-apps"
CONFIG_USER_ENTRYPOINT="custom_main"
.. note::
You can only access the ``../custom-apps/Kconfig`` file if
``CONFIG_APPS_DIR`` is set to ``../custom-apps`` **before** running
``make menuconfig``. If you start with an existing configuration, you may
face a "chicken-and-egg" situation. One workaround is to manually edit
the ``.config`` file before running ``make menuconfig``.
Alternatively, if you use the ``tools/configure.sh`` script, you can specify the
custom-apps directory from the command line:
.. code-block:: shell
tools/configure.sh -a ../custom_apps <board>:<config>
Afterward, just build NuttX as you normally would. When you run the program that
was built with your custom application directory, you should see:
.. code-block:: shell
Hello, World!!

Debugging ELF Loadable Modules
==============================
.. warning::
Migrated from:
https://cwiki.apache.org/confluence/display/NUTTX/Debugging+ELF+Loadable+Modules
Debugging ELF modules loaded in memory can be tricky because the load address
in memory does not match the addresses in the ELF file. This challenge has long
existed for debugging uClinux programs and Linux kernel modules; the same
solution can be used with NuttX ELF files (and probably with NxFLAT modules as
well). Below is a summary of one way to approach this:
1. Get ELF Module Load Address
==============================
Put a change in ``nuttx/binfmt`` so that you print the address where the ELF
text was loaded into memory.
Turning on BINFMT debug (``CONFIG_DEBUG_BINFMT=y``) should give you the same
information, although it may also provide more output than you really want.
Alternatively, you could place a ``printf()`` at the beginning of your ``main()``
function so that your ELF module can print its own load address. For example,
the difference between the address of ``main()`` in your object file and the
address of ``main()`` at run time reveals the actual load address.
2. Make the ELF Module Wait for You
===================================
Insert an infinite loop in the ``main()`` routine of your ELF program. For
example:
.. code-block:: c
volatile bool waitforme;
int main (int arc, char **argv)
{
while (!waitforme);
...
When you start the ELF program, you will see where it was loaded in memory, and
the ELF program will remain stuck in the infinite loop. It will continue to
wait for ``waitforme`` to become true before proceeding.
3. Start the Debugger
=====================
Start the debugger, connect to the GDB server, and halt the program. If your
debugger is well-behaved, it should stop at the infinite loop in ``main()``.
4. Load Offset Symbols
======================
Load symbols using the offset where the ELF module was loaded:
.. code-block:: shell
(gdb) add-symbol-file <myprogram> <load-address>
Here, ``<myprogram>`` is your ELF file containing symbols, and
``<load-address>`` is the address where the program text was actually loaded (as
determined above). Single-step a couple of times and confirm that you are in the
infinite loop.
5. And Debug
============
Set ``waitforme`` to a non-zero value. Execution should exit the infinite loop,
and now you can debug the ELF program loaded into RAM in the usual way.
An Easier Way?
==============
There might be an alternative that allows you to step into the ELF module
without modifying the code to include the ``waitforme`` loop. You could place a
breakpoint on the OS function ``task_start()``. That function runs before your
ELF program starts, so you should be able to single-step from the OS code
directly into your loaded ELF application—no changes to the ELF application
required.
When you step into the application's ``main()``, you have the relocated address
of ``main()`` and can use that address (see step #1) to compute the load offset.

ELF Programs – No Symbol Tables
===============================
.. warning::
Migrated from:
https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=139629542
You can easily extend the firmware in your released, embedded system using ELF
programs provided via a file system (for example, an SD card or downloaded into
on-board SPI FLASH). In order to support such post-release updates, your
released firmware would have to support execution of fully linked, relocatable
ELF programs loaded into RAM (see, for example, ``apps/examples/elf``).
The files shown in this Wiki page can be downloaded `here <https://cwiki.apache.org/confluence/download/attachments/139629402/elfprog-nosymtab.tar.gz?version=1&modificationDate=1576735520000&api=v2>`_.
Alan Carvalho de Assis has also made a video based on this example in the
YouTube `NuttX Channel <https://www.youtube.com/watch?v=oL6KAgkTb8M>`_.
Creating the Export Package
===========================
At the time that you release the firmware, you should create and save an
export package. The export package is all that you need to create
post-release, add-on modules for your embedded system. Let's illustrate this
using the ``STM32F4-Discovery`` networking ``NSH`` configuration with the
``STM32F4DIS-BB`` baseboard. (This demonstration assumes that you also have
support for some externally modifiable media in the board configuration, such
as removable media like an SD card, or a USB FLASH stick, an internal file
system remotely accessible via USB MSC, FTP, or any remote file system (NFS).
The networking ``NSH`` configuration uses the SD card on the STM32 baseboard
for this demonstration. Other ``NSH`` configurations could be used, provided
that you supply the necessary file system support in some fashion.)
(No baseboard? You can add file system support to the basic ``STM32F4-Discovery``
board by following these instructions:
`USB FLASH drive <https://www.youtube.com/watch?v=5hB5ZXpRoS4>`_
or `SD card <https://www.youtube.com/watch?v=H28t4RbOXqI>`_.)
.. code-block:: shell
$ make distclean
$ tools/configure.sh -c stm32f4discovery:netnsh
$ make menuconfig
Your released firmware would have to have been built with a few important
configuration settings:
1. Disable networking (Only because it is not needed in this example):
.. code-block:: shell
# CONFIG_NET is not set
2. Enable basic ELF binary support with no built-in symbol table support:
.. code-block:: shell
CONFIG_ELF=y
CONFIG_LIBC_EXECFUNCS=y
# CONFIG_EXECFUNCS_HAVE_SYMTAB is not set
3. Enable PATH variable support:
.. code-block:: shell
CONFIG_BINFMT_EXEPATH=y
CONFIG_PATH_INITIAL="/bin"
# CONFIG_DISABLE_ENVIRON not set
4. Enable execution of ELF files from the ``NSH`` command line:
.. code-block:: shell
CONFIG_NSH_FILE_APPS=y
.. note::
You must enable some application that uses ``printf()``. This is necessary
to assure that the symbol ``printf()`` is included in the base system.
Here we assume that you include the "Hello, World!" example from
``apps/examples/hello``:
.. code-block:: shell
CONFIG_EXAMPLES_HELLO=y
Then we can build the NuttX firmware image and the export package:
.. code-block:: shell
$ make
$ make export
When ``make export`` completes, you will find a ZIP'ed package in the top-level
NuttX directory called ``nuttx-export-x.y.zip`` (for version ``x.y``). The
version is determined by the ``.version`` file in the same directory. The
content of this ZIP file is the following directory structure:
.. code-block:: shell
nuttx-export-x.x
|- arch/
|- build/
|- include/
|- libs/
|- startup/
|- System.map
`- .config
The Add-On Build Directory
==========================
In order to create the add-on ELF program, you will need (1) the export
package, (2) the program build ``Makefile``, (3) a linker script used by the
``Makefile``, and (4) a Bash script to create a linker script. That
``Makefile`` and Bash Script are discussed in the following paragraphs.
.. note::
These example files implicitly assume a GNU tool chain is used and, in at
least one place, that the target is an ARMv7-M platform. A non-GNU tool
chain would probably require a significantly different ``Makefile`` and
linker script. There is at least one ARMv7-M specific change that would
have to be made for other platforms in the script that creates the linker
script (``mkdefines.sh``).
Hello Example
=============
To keep things manageable, let's use a concrete example. Suppose the ELF
program that we wish to add to the release code is the single source file
``hello.c``:
.. code-block:: c
#include <stdio.h>
int main(int argc, char **argv)
{
printf("Hello from Add-On Program!\n");
return 0;
}
Let's say that we have a directory called ``addon`` and it contains the
``hello.c`` source file, a ``Makefile`` that will create the ELF program, and a
Bash script called ``mkdefines.sh`` that will create a linker script.
Building the ELF Program
========================
The first step in creating the ELF program is to unzip the Export Package. We
start with our ``addon`` directory containing the following:
.. code-block:: shell
$ cd addon
$ ls
gnu-elf.ld hello.c Makefile mkdefines.sh nuttx-export-7.25.zip
Where:
- ``gnu-elf.ld`` is the linker script.
- ``hello.c`` is our example source file.
- ``Makefile`` will build our ELF program and symbol table.
- ``mksymtab.h`` is the Bash script that will create the symbol table for the
ELF program.
- ``nuttx-export-7.25.zip`` is the Export Package for NuttX-7.25.
We unzip the Export Package like:
.. code-block:: shell
$ unzip nuttx-export-7.25.zip
Then we have a new directory called ``nuttx-export-7.25`` that contains all of
the content from the released NuttX code that we need to build the ELF
program.
The Makefile
============
The ELF program is created simply as:
.. code-block:: shell
$ make
This uses the following ``Makefile`` to generate several files:
- ``hello.o``: The compiled ``hello.c`` object.
- ``hello.r``: A "partially linked" ELF object that still has undefined
symbols.
- ``hello``: The fully linked, relocatable ELF program.
- ``linker.ld``: A linker script created by ``mkdefines.sh``.
Only the resulting ``hello`` is needed.
Below is the ``Makefile`` used to create the ELF program:
.. code-block:: shell
include nuttx-export-7.25/build/Make.defs
# Long calls are need to call from RAM into FLASH
ARCHCFLAGS += -mlong-calls
ARCHWARNINGS = -Wall -Wstrict-prototypes -Wshadow -Wundef
ARCHOPTIMIZATION = -Os -fno-strict-aliasing -fno-strength-reduce -fomit-frame-pointer
ARCHINCLUDES = -I. -isystem nuttx-export-7.25/include
CFLAGS = $(ARCHCFLAGS) $(ARCHWARNINGS) $(ARCHOPTIMIZATION) $(ARCHINCLUDES) -pipe
CROSSDEV = arm-none-eabi-
CC = $(CROSSDEV)gcc
LD = $(CROSSDEV)ld
STRIP = $(CROSSDEV)strip --strip-unneeded
# Setup up linker command line options
LDRELFLAGS = -r
LDELFFLAGS = -r -e main
LDELFFLAGS += -T defines.ld -T gnu-elf.ld
# This might change in a different environment
OBJEXT ?= .o
# This is the generated ELF program
BIN = hello
REL = hello.r
# These are the sources files that we use
SRCS = hello.c
OBJS = $(SRCS:.c=$(OBJEXT))
# Build targets
all: $(BIN)
.PHONY: clean
$(OBJS): %$(OBJEXT): %.c
$(CC) -c $(CFLAGS) -o $@ $<
System.map: nuttx-export-7.25/System.map
cat nuttx-export-7.25/System.map | sed -e "s/\r//g" >System.map
$(REL): $(OBJS)
$(LD) $(LDRELFLAGS) -o $@ $<
defines.ld: System.map $(REL)
./mkdefines.sh System.map "$(REL)" >defines.ld
$(BIN): defines.ld $(REL)
$(LD) $(LDELFFLAGS) -o $@ $(REL)
$(STRIP) $(REL)
clean:
rm -f $(BIN)
rm -f $(REL)
rm -f defines.ld
rm -f System.map
rm -f *.o
The Linker Script
=================
Two linker scripts are used. One is a normal file (we'll call it the main
linker script), and the other, ``defines.ld``, is created on-the-fly as
described in the next section.
The main linker script, ``gnu-elf.ld``, contains the following:
.. code-block:: shell
SECTIONS
{
.text 0x00000000 :
{
_stext = . ;
*(.text)

.debug_pubnames 0 : { *(.debug_pubnames) }
.debug_aranges 0 : { *(.debug_aranges) }
}
Creating the ``defines.ld`` Linker Script
=========================================
The additional linker script ``defines.ld`` is created through a three-step
process:
1. The ``Makefile`` generates a partially linked ELF object, ``hello.r``.
2. The ``Makefile`` then invokes the ``mkdefines.sh`` script, which generates
the ``defines.ld`` linker script that provides values for all of the
undefined symbols.
3. Finally, the ``Makefile`` produces the fully linked, relocatable ``hello``
ELF object using the ``defines.ld`` linker script.
Below is the version of ``mkdefines.sh`` used in this demo:
.. code-block:: bash
#!/bin/bash
usage="Usage: $0 <system-map> <relprog>"
# Check for the required path to the System.map file
sysmap=$1
if [ -z "$sysmap" ]; then
echo "ERROR: Missing <system-map>"
echo ""
echo $usage
exit 1
fi
# Check for the required partially linked file
relprog=$2
if [ -z "$relprog" ]; then
echo "ERROR: Missing <program-list>"
echo ""
echo $usage
exit 1
fi
# Verify the System.map and the partially linked file
if [ ! -r "$sysmap" ]; then
echo "ERROR: $sysmap does not exist"
echo ""
echo $usage
exit 1
fi
if [ ! -r "$relprog" ]; then
echo "ERROR: $relprog does not exist"
echo ""
echo $usage
exit 1
fi
# Extract all of the undefined symbols from the partially linked file and create a
# list of sorted, unique undefined variable names.
varlist=`nm $relprog | fgrep ' U ' | sed -e "s/^[ ]*//g" | cut -d' ' -f2 | sort - | uniq`
# Now output the linker script that provides a value for all of the undefined symbols
for var in $varlist; do
map=`grep " ${var}$" ${sysmap}`
if [ -z "$map" ]; then
echo "ERROR: Variable $var not found in $sysmap"
echo ""
echo $usage
exit 1
fi
varaddr=`echo ${map} | cut -d' ' -f1`
echo "${var} = 0x${varaddr} | 0x00000001;"
done
This script uses the ``nm`` utility to find all of the undefined symbols in the
ELF object, then searches for the address of each undefined symbol in the
``System.map`` that was created when the released firmware was built. Finally,
it uses the symbol name and the symbol address to create each symbol table
entry.
.. note::
- For the ARMv7-M architecture, bit 0 of the address must be set to indicate
thumb mode. If you are using a different architecture that requires
normal aligned addresses, you will need to change the following line by
eliminating the ORed value:
.. code-block:: shell
echo "${var} = 0x${varaddr} | 0x00000001;"
- If the new ELF module uses a symbol that is not provided in the base
firmware and, hence, not included in the ``System.map`` file, this script
will fail. In that case, you will need to provide the missing logic
within the ELF program itself, if possible.
- The technique as described here is only valid in the FLAT build mode. It
could probably also be extended to work in the PROTECTED mode by
substituting ``User.map`` for ``System.map``.
Here is an example ``defines.ld`` created by ``mkdefines.sh``:
.. code-block:: shell
printf = 0x0800aefc | 0x00000001 ;
Replacing an NSH Built-In Function
==================================
Files can be executed by ``NSH`` from the command line by simply typing the
name of the ELF program. This requires:
1. That the feature be enabled with``CONFIG_NSH_FILE_APP=y``
2. That support for the PATH variable is enabled (``CONFIG_BINFMT_EXEPATH=y`` and
``CONFIG_PATH_INITIAL`` set to the mount point of the file system that
may contain ELF programs).
Suppose, for example, I have a built-in application called ``hello``. Before
installing the new replacement ``hello`` ELF program in the file system, this
is the version of ``hello`` that ``NSH`` will execute:
.. code-block:: shell
nsh> hello
Hello, World!
nsh>
In the above configuration, ``NSH`` will first attempt to run the program called
``hello`` from the file system. This will fail because we have not yet placed
our custom ``hello`` ELF program in the file system. So instead, ``NSH`` will
fall back and execute the built-in application called ``hello``.
In this way, any command known to ``NSH`` can be replaced by an ELF program
installed in a mounted file system directory that is found via the PATH
variable.
Now suppose that we do add our custom ``hello`` to the file system. When
``NSH`` attempts to run the program called ``hello`` from the file system, it
will run successfully. The built-in version will be ignored. It has been
replaced with the version in the file system:
.. code-block:: shell
nsh> mount -t vfat /dev/mmcsd0 /bin
nsh> hello
Hello from Add-On Program!
nsh>
Version Dependency
==================
.. note::
This technique generates ELF programs using fixed addresses from the
``System.map`` file of a versioned release. The generated ELF programs can
only be used with that specific firmware version. A crash will most likely
result if used with a different firmware version, because the addresses
from the ``System.map`` will not match the addresses in a different version
of the firmware.
The alternative approach using :doc:`Symbol Tables <fully_linked_elf>` is more
or less version independent.
Tightly Coupled Memories
========================
Most MCUs based on ARMv7-M family processors support some kind of Tightly
Coupled Memory (TCM). These TCMs have somewhat different properties for
specialized operations. Depending on the bus matrix of the processor, you may
not be able to execute programs from TCM. For instance, the ``STM32 F4``
supports Core Coupled Memory (CCM), but since it is tied directly to the D-bus,
it cannot be used to execute programs! On the other hand, the ``STM32F3`` has a
CCM that is accessible to both the D-Bus and the I-Bus, in which case it
should be possible to execute programs from this TCM.
.. image:: ./image/system_arch_stm32f42xx_and_f43xx.png
.. image:: ./image/system_arch_stm32f303xBC_and_f358xC.png
When ELF programs are loaded into memory, the memory is allocated from the
heap via a standard memory allocator. By default with the ``STM32 F4``, the
CCM is included in ``HEAP`` and will typically be allocated first. If CCM
memory is allocated to hold the ELF program, a hard-fault will occur
immediately when you try to execute the ELF program in memory.
Therefore, it is necessary on ``STM32 F4`` platforms to include the following
configuration setting:
.. code-block:: shell
CONFIG_STM32_CCMEXCLUDE=y
With that setting, the CCM memory will be excluded from the heap, and so will
never be allocated for ELF program memory.

Multiple NSH Sessions
=====================
.. warning::
Migrated from:
https://cwiki.apache.org/confluence/display/NUTTX/Multiple+NSH+Sessions
Q:
I would like to run the NuttShell on multiple serial ports, but haven't
figured it out yet; can you point me in the right direction?
A:
Easy. Don't use ``apps/examples/nsh_main.c``. Create your own main function
something like this (with all error handling omitted for simplicity). By the
way, this is all standard POSIX stuff that you can get detailed information
about by just Googling `dup2` or maybe `I/O redirection`:
.. code-block:: c
int my_main(int argc, char **argv)
{
const char *tty = argv[1];
int fd = open(tty, O_RDWR);
(void)dup2(fd, 0);
(void)dup2(fd, 1);
(void)dup2(fd, 2);
close(fd);
...
}
And the rest is just like the original ``nsh_main()`` function (in fact,
perhaps the existing ``nsh_main()`` function could be optionally extended to
accept a console device string?). Then you can start a new NSH session on any
TTY like:
.. code-block:: none
nsh> mynsh /dev/ttyS2 &
This should cause a new NSH session to appear on ``ttyS2``. That session will
persist until you do the following from the new session:
.. code-block:: none
nsh> exit
Then the new session, i.e., ``my_main()`` will exit.
If you were to do something like:
.. code-block:: none
nsh> mynsh /dev/console
then you would get nested NSH sessions on the same console. The first session
would halt and wait for the second session to take control of the console until
it exits. Then the first session will take over console again.
NuTTY
=====
In a previous discussion, there was talk about implementing the moral equivalent
of getty in NuttX (of course, it would be called "nutty"). A simple
implementation of nutty would work like this:
1. It would wait on ``poll()`` on every (configured) serial device.
2. Whenever it is awakened, it would start something like ``my_main()`` above
on the active serial port.
3. NSH has an option to enable logins, but it would be better to remove the
existing login information from NSH and centralize it in nutty.
That way, you could connect to any TTY, hit enter, and you would get an NSH
session. Hmm... it is not clear how nutty would get the TTY back after the
session is closed. That part may require some additional thought.
Other Ideas
===========
There are other ways to get multiple NSH sessions:
- Telnet already supports multiple sessions.
- Implement the existing NSH as an ELF program, then you can get multiple NSH
sessions with ``posix_spawn`` by simply redirecting I/O.
- Using the tiny NxWM window managers, multiple NSH windows are already
supported.

===========================
NSH Network Link Management
===========================
.. warning::
Migrated from:
https://cwiki.apache.org/confluence/display/NUTTX/NSH+Network+Link+Management
In the past, if the network was not connected when NuttX started, two problems
could arise:
1. It could take a very long time for the NSH prompt to appear because of the
sequential initialization (for example, when the network cable is not
connected).
2. After NuttX came up, installing the network cable would not enable the
network; the only way to recover networking was to connect the cable and
reset the board.
Network link management capability has now been added to NSH to address these
problems.
Configuration Options
=====================
A simple feature can be enabled to move network initialization to a separate
thread so that it is no longer performed sequentially. With this feature, the
network bringup occurs asynchronously, and the NSH prompt appears immediately
(although the network may not be available until some time later). That feature
is enabled with the following setting and is the first prerequisite for the full
NSH link management feature:
- ``CONFIG_NSH_NETINIT_THREAD``. Refer to the help text in the Kconfig file for
this option (``apps/nshlib/Kconfig``). Additional information about this
setting is included there.
The logic that implements NSH network management is provided in
``apps/nshlib/nsh_netinit.c``. The behavior of that logic depends on multiple
configuration settings. First, there are some additional prerequisites that
must be satisfied:
- ``CONFIG_NETDEV_PHY_IOCTL``
Enable PHY IOCTL commands in the Ethernet device driver. Special IOCTL
commands must be provided by the Ethernet driver to support certain PHY
operations needed for link management. These operations are not complex and
are implemented for Atmel SAM4/4, SAMA5 families, and for the STMicro STM32.
See ``nuttx/arch/arm/src/sam34/sam_emac.c``,
``nuttx/arch/arm/src/sam34/sam_emaca.c``, ``sam_emacb.c``, and ``sam_gmac.c``,
and ``nuttx/arch/arm/src/stm32/stm32_eth.c``.
- ``CONFIG_ARCH_PHY_INTERRUPT``
This is not a user-selectable option. Rather, it is set when selecting a board
that supports PHY interrupts. In most architectures, the PHY interrupt is not
directly associated with the Ethernet driver. Instead, the PHY interrupt is
provided through some board-specific GPIO, and the board-specific logic must
provide support for that GPIO interrupt. Specifically, the board logic must:
1. Provide the function ``arch_phy_irq()`` as described and prototyped in
``nuttx/include/nuttx/arch.h``.
2. Select ``CONFIG_ARCH_PHY_INTERRUPT`` in the board configuration file to
advertise that ``arch_phy_irq()`` is supported.
Examples can be found at:
- ``nuttx/boards/arm/sama5/sama5d3x-ek/src/sam_ethernet.c``
- ``nuttx/boards/arm/sama5/sama5d3-xplained/src/sam_ethernet.c``
- ``nuttx/boards/arm/sama5/sama5d4-ek/src/sam_ethernet.c``
- Other requirements: UDP support must be enabled (``CONFIG_NET_UDP``), and
signals must not be disabled (``CONFIG_DISABLE_SIGNALS``).
With all these prerequisites in place, NSH network management can be enabled on
the NSH network initialization thread by selecting these additional options:
- ``CONFIG_NSH_NETINIT_MONITOR``
By default, the network initialization thread brings up the network (or
fails while trying) then exits, freeing all resources it used. If this option
is selected, however, the network initialization thread will persist
indefinitely to monitor the network status. Should the network go down (for
example, if the cable is removed), the thread will monitor the link status
and attempt to bring the network back up. In this scenario, the resources
required for network initialization are never released.
If the network monitor is selected, additional options control its behavior:
- ``CONFIG_NSH_NETINIT_SIGNO``
The network monitor logic receives signals when there is a change in link
status. This setting can be used to customize the signal number to avoid
conflicts.
- ``CONFIG_NSH_NETINIT_RETRYMSEC``
When the network is down, the initialization thread will periodically attempt
to bring the network back up. Because this can be time-consuming, the retry
operation is performed only at the interval specified by this value, in
milliseconds.
- ``CONFIG_NSH_NETINIT_THREAD_STACKSIZE``
The stack size for the network initialization thread.
- ``CONFIG_NSH_NETINIT_THREAD_PRIORITY``
The network initialization thread priority.
Overview of the Operation
=========================
Below is a summary of how the NSH management thread operates:
1. During initialization, the thread opens a UDP socket for IOCTL operations
and connects a signal handler.
2. It enters a loop. At the beginning of each loop iteration, the thread
uses an IOCTL command to register (or re-register) with the Ethernet device
to receive a signal whenever the PHY reports a link up or link down
interrupt. Re-registration is necessary because the notification disarms
after each PHY interrupt.
3. The thread reads the link status from both the PHY and the Ethernet device.
If they disagree, the network monitor uses an IOCTL command to bring the
Ethernet driver up or down to match the current state of the network. If the
network is lost, the monitor brings the Ethernet driver down; if the network
is regained, the monitor brings the Ethernet driver back up and re-establishes
the connection.
4. If the PHY and the Ethernet driver agree on the link state, no action is
performed.
5. At the end of the loop, the network monitor waits for a PHY interrupt or a
timeout. When either occurs, control returns to the top of the loop, and the
process repeats.
6. If a PHY interrupt happens, a signal is delivered to the task and handled by
the network monitor’s signal handler, which posts a semaphore to immediately
re-awaken the network monitor from its wait.

ELF Programs – With Symbol Tables
=================================
.. warning::
Migrated from:
https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=139629543
Updating a Release System with ELF Programs – With Symbol Tables
================================================================
You can easily extend the firmware in your released, embedded system using
ELF programs provided via a file system. For example, an SD card or, perhaps,
downloaded into on-board SPI FLASH.
In order to support such post-release updates, your released firmware must
support execution of ELF programs loaded into RAM and symbol tables also
provided via the file system (see `apps/examples/elf`).
The files shown in this Wiki page can be downloaded
`here <https://cwiki.apache.org/confluence/download/attachments/139629402/elfprog-wsymtab.tar.gz?version=1&modificationDate=1576735523000&api=v2>`_
Creating a Symbol Table
=======================
There are several ways to create an application symbol table. Only two are
compatible with the example provided here:
1. **Board-specific Bring-up Logic**
Build a symbol table into the base firmware and add it to your
board-specific bring-up logic. This technique is typically used in kernel
mode with ``CONFIG_USER_INITPATH=y``.
In this setup, the system does not initialize using a standard C call like
``nsh_main()``. Instead, it starts with an ``init`` ELF program, similar to
how Linux initializes. The configuration option
``CONFIG_EXECFUNCS_SYMTAB_ARRAY`` initializes the system with a minimal set
of symbols required by the ``init`` program. Once initialized, the ``init``
program would typically call ``boardctl()`` to put the final symbol table in
place.
To enable this method, you must:
- Set ``CONFIG_EXECFUNCS_HAVE_SYMTAB=y`` in your configuration.
- Provide a symbol table with the global name ``CONFIG_EXECFUNCS_SYMTAB_ARRAY`` with the variable name ``CONFIG_EXECFUNCS_NSYMBOLS_VAR`` that holds the number of symbol entries. The default symbol table name is ``g_symtab``.
In this example, let's illustrate this using an STM32F4-Discovery
configuration. We will assume that you have modified the
``boards/arm/stm32/stm32fdiscovery/src/stm32_bringup.c`` file, adding the
following:
.. code-block:: c
#include <stdio.h>
#include <nuttx/binfmt/symtab.h>
const struct symtab_s g_symtab[] = {
{"printf", (FAR void *)printf}
};
int g_nsymbols = 1;
This is a simple symbol table containing only the symbol string "printf,"
whose value is the address of the function ``printf()``.
There is, of course, a lot more that could be said about generating symbol
tables. NuttX provides specialized tools in the ``tools/`` directory and
instructions elsewhere for generating more extensive symbol tables. However,
this example keeps things simple to focus on the core functionality.
2. **Application Logic**
Alternatively, the symbol table can be provided dynamically by the
application itself, using the ``boardctl()`` system interface. The specific
``boardctl()`` command to use is ``BOARDIOC_APP_SYMTAB``. This command
provides the symbol table in the same way as the board-specific logic but
allows for application-level control.
To use this approach, you need to:
- Enable the configurations ``CONFIG_LIB_BOARDCTL=y`` and ``CONFIG_BOARDCTL_APP_SYMTAB=y``.
- Include application logic to provide the symbol table. If ``CONFIG_EXAMPLES_NSH_SYMTAB=y`` is set, NSH can handle this automatically.
Export Package
==============
At the time of firmware release, you should create and save an export package.
This export package contains all the necessary files required to create
post-release add-on modules for your embedded system.
For demonstration purposes, we use the STM32F4-Discovery with the network NSH
configuration. This setup assumes that you have the STM32F4DIS-BB baseboard.
The demonstration also requires support for externally modifiable media, such
as:
- Removable media, like an SD card or USB flash drive.
- An internal file system remotely accessible via USB MSC, FTP, or other
protocols.
- A remote file system, such as NFS.
In this demonstration, the networking NSH configuration uses the SD card on
the STM32 baseboard. Other NSH configurations can also be used, provided they
supply the necessary file system support.
(No baseboard? You can add file system support to the basic ``STM32F4-Discovery``
board by following these instructions:
`USB FLASH drive <https://www.youtube.com/watch?v=5hB5ZXpRoS4>`_
or `SD card <https://www.youtube.com/watch?v=H28t4RbOXqI>`_.)
Example for STM32F4-Discovery:
.. code-block:: shell
$ make distclean
$ tools/configure.sh -c stm32f4discovery:netnsh
$ make menuconfig
Required configurations:
- Disable networking: ``# CONFIG_NET is not set``
- Enable ELF binary support: ``CONFIG_ELF=y``, ``CONFIG_LIBC_EXECFUNCS=y``,
``CONFIG_EXECFUNCS_HAVE_SYMTAB=y``, ``CONFIG_EXECFUNCS_SYMTAB_ARRAY="g_symtab"`` and
``CONFIG_EXECFUNCS_NSYMBOLS_VAR="g_nsymbols"``
- Enable PATH variable support: ``CONFIG_BINFMT_EXEPATH=y``,
``CONFIG_PATH_INITIAL="/bin"``
- Enable execution from NSH: ``CONFIG_NSH_FILE_APPS=y``
Then, build the NuttX firmware image and the export package:
.. code-block:: shell
$ make
$ make export
When ``make export`` completes, you will find a ZIP package in the top-level
NuttX directory called ``nuttx-export-x.y.zip`` (where x.y corresponds to the
version, determined by the .version file in the same directory). The contents
of this ZIP file are organized as follows:
.. code-block:: text
nuttx-export-x.x
|- arch/
|- build/
|- include/
|- libs/
|- startup/
|- System.map
`- .config
Add-On Build Directory
======================
In order to create the add-on ELF program, you will need:
1. The export package.
2. A program build Makefile.
3. A linker script used by the Makefile.
The example Makefile discussed below assumes the use of a GNU toolchain. Note
that non-GNU toolchains would likely require a significantly different
Makefile and linker script.
Hello Example
=============
To keep things manageable, let's use a concrete example. Suppose the ELF
program that we wish to add to the release code is the simple
source file ``hello.c``:
.. code-block:: c
#include <stdio.h>
int main(int argc, char **argv)
{
printf("Hello from Add-On Program!\n");
return 0;
}
Let's say that we have a directory called ``addon`` that contains the following:
1. The ``hello.c`` source file.
2. A Makefile to build the ELF program.
3. A linker script called ``gnu-elf.ld`` needed by the Makefile.
4. The export package ``nuttx-export-7.25.zip``.
Building the ELF Program
========================
The first step in creating the ELF program is to unzip the export
package. Starting in the ``addon`` directory:
.. code-block:: shell
$ cd addon
$ ls
gnu-elf.ld hello.c Makefile nuttx-export-7.25.zip
Where:
- ``gnu-elf.ld`` is the linker script.
- ``hello.c`` is the example source file.
- ``Makefile`` builds the ELF program.
- ``nuttx-export-7.25.zip`` is the export package from NuttX 7.25.
Unzip the export package as follows:
.. code-block:: shell
$ unzip nuttx-export-7.25.zip
This creates a new directory called ``nuttx-export-7.25``, containing
all the content from the released NuttX code required to build
the ELF program.
The Makefile
============
To build the ELF program, simply run:
.. code-block:: shell
$ make
This uses the following Makefile to generate several files:
- ``hello.o``: The compiled object file for ``hello.c``.
- ``hello``: The linked ELF program.
Only the resulting ``hello`` file is needed.
The Makefile used to create the ELF program is as follows:
.. code-block:: shell
include nuttx-export-7.25/build/Make.defs
# Long calls are need to call from RAM into FLASH
ARCHCFLAGS += -mlong-calls
ARCHWARNINGS = -Wall -Wstrict-prototypes -Wshadow -Wundef
ARCHOPTIMIZATION = -Os -fno-strict-aliasing -fno-strength-reduce -fomit-frame-pointer
ARCHINCLUDES = -I. -isystem nuttx-export-7.25/include
CFLAGS = $(ARCHCFLAGS) $(ARCHWARNINGS) $(ARCHOPTIMIZATION) $(ARCHINCLUDES) -pipe
CROSSDEV = arm-none-eabi-
CC = $(CROSSDEV)gcc
LD = $(CROSSDEV)ld
STRIP = $(CROSSDEV)strip --strip-unneeded
# Setup up linker command line options
LDELFFLAGS = -r -e main
LDELFFLAGS += -T gnu-elf.ld
# This might change in a different environment
OBJEXT ?= .o
# This is the generated ELF program
BIN = hello
# These are the sources files that we use
SRCS = hello.c
OBJS = $(SRCS:.c=$(OBJEXT))
# Build targets
all: $(BIN)
.PHONY: clean
$(OBJS): %$(OBJEXT): %.c
$(CC) -c $(CFLAGS) $< -o $@
$(BIN): $(OBJS)
$(LD) $(LDELFFLAGS) -o $@ $^
$(STRIP) $(BIN)
clean:
rm -f $(BIN)
rm -f *.o
The Linker Script
=================
The linker script that I am using in this example, gnu-elf.ld,
contains the following:
.. code-block:: shell
SECTIONS
{
.text 0x00000000 :
{
_stext = . ;

.debug_line 0 : { *(.debug_line) }
.debug_pubnames 0 : { *(.debug_pubnames) }
.debug_aranges 0 : { *(.debug_aranges) }
}
Replacing NSH Built-In Functions
================================
Files can be executed by NSH from the command line by simply typing the name
of the ELF program. This requires (1) that the feature be enabled with
``CONFIG_NSH_FILE_APP=y`` and (2) that support for the PATH variable is
enabled with ``CONFIG_BINFMT_EXEPATH=y`` and ``CONFIG_PATH_INITIAL`` set to
the mount point of the file system that may contain ELF programs.
In this example, there is no application in the base firmware called
``hello``. So attempts to run ``hello`` will fail:
.. code-block:: shell
nsh> hello
nsh: hello: command not found
nsh>
But if we mount the SD card containing the ``hello`` image that we created
above, then we can successfully execute the ``hello`` command:
.. code-block:: shell
nsh> mount -t vfat /dev/mmcsd0 /bin
nsh> ls /bin
/bin:
System Volume Information/
hello
nsh> hello
Hello from Add-On Program!
nsh>
Here we showed how you can add a new command to NSH to a product without
modifying the base firmware. We can also replace or update an existing
built-in application in this way:
In the above configuration, NSH will first attempt to run the program called
``hello`` from the file system. This will fail because we have not yet put
our custom ``hello`` ELF program in the file system. So instead, NSH will
fallback and execute the built-in application called ``hello``. In this way,
any command known to NSH can be replaced from an ELF program installed in a
mounted file system directory that can be found via the PATH variable.
After we do add our custom ``hello`` to the file system, when NSH attempts to
run the program called ``hello`` from the file system it will run
successfully. The built-in version will be ignored. It has been replaced with
the version in the file system.
Tightly Coupled Memories
========================
Most MCUs based on ARMv7-M family processors support some kind of Tightly
Coupled Memory (TCM). These TCMs have somewhat different properties for
specialized operations. Depending on the bus matrix of the processor, you
may not be able to execute programs from the TCM. For instance, the STM32 F4
supports Core Coupled Memory (CCM), but since it is tied directly to the
D-bus, it cannot be used to execute programs! On the other hand, the STM32F3
has a CCM that is accessible to both the D-Bus and the I-Bus, in which case
it should be possible to execute programs from this TCM.
.. image:: ./image/system_arch_stm32f42xx_and_f43xx.png
.. image:: ./image/system_arch_stm32f303xBC_and_f358xC.png
When ELF programs are loaded into memory, the memory is allocated from the
heap via a standard memory allocator. By default with the STM32 F4, the CCM
is included in the heap and will typically be allocated first. If CCM memory
is allocated to hold the ELF program in memory, then a hard-fault will occur
immediately when you try to execute the ELF program in memory.
Therefore, it is necessary on STM32 F4 platforms to include the following
configuration setting:
.. code-block:: shell
CONFIG_STM32_CCMEXCLUDE=y
With that setting, the CCM memory will be excluded from the heap and so will
never be allocated for ELF program memory.

How to port
===========================================
This guide explains "How to port NuttX".
At this guide, the scope of porting is adding a new SoC or board directory,
which can be built and has a working example that boots to the NuttShell (NSH).
The goal of porting is to comfirm the booting NuttShell(NSH), the pass of "ostest"
and the timer.
Porting a new SoC and board to NuttX requires modifications on arch,
SoC and board directories.
For the details,
see :doc:`/quickstart/organization`,
:doc:`/components/arch/index`,
:doc:`/components/boards`.
To port NuttX properly, we have to understand the boot sequence and
related kernel configurations.
Following links explain them, although these depend on
specific kernel version and configurations.
(To understand them, we have to read the code deeply.)
.. toctree::
port_bootsequence.rst
port_relatedkernelconfigrations.rst
About the implementation, the build system tells you minimal implementation of SoC/Board directory,
these implementations are almost done by copying and pasting from other SoC/Board
directory if there is the source code for the target HW IP in upstream.
If there is not the source code in upstream, the porter has to implement it by himself.
Porting procedure
=================
At first, you have to read and execute :doc:`/quickstart/install` and :doc:`/quickstart/compiling_make`.
After that, try follwoing procedure.
+------+---------------+--------------------------------------------------------------------+
| Step | Process | Comment |
+------+---------------+--------------------------------------------------------------------+
| 1 | Add the SoC | |
+------+---------------+--------------------------------------------------------------------+
| 2 | Add the Board | If the board was not sold in the market, |
| | | the board directory should be located out-of-tree. |
| | | For details see :doc:`/guides/customboards`. |
| | | And if you wanted to add own apps, see :doc:`/guides/customapps`. |
+------+---------------+--------------------------------------------------------------------+
| 3 | Configure | The configure needs to understand related kernel configurations. |
| | | see :doc:`/guides/port_relatedkernelconfigrations`. |
+------+---------------+--------------------------------------------------------------------+
| 4 | Compile | The compile tells you which source files are needed in SoC/Board |
| | | directory to pass the compile. |
+------+---------------+--------------------------------------------------------------------+
| 5 | Link | The link tells you which symbols are needed in SoC/Board directory |
| | | to pass the link. |
+------+---------------+--------------------------------------------------------------------+
| 6 | Implement | Do implement the symbols which are needed by the link. |
+------+---------------+--------------------------------------------------------------------+
| 7 | Verify | Do "apps/testing/ostest". |
| | | I think the pass of ostest is the one of proof for proper porting. |
| | | And check the timer implementation whether the kernel could |
| | | count the time accurately or not. |
+------+---------------+--------------------------------------------------------------------+
Porting Case Studies
===============================
These porting guides depend on specific kernel versions, as some code structures have changed over time. They will still
provide a general idea on how to port.

The diagram of boot sequence
============================
The premise of this sequence diagram is NuttX12.4.0, cxd56xx, non-SMP and Flat build.
The beginning of boot sequence is __start().
__start() will call nx_start(). nx_start() will initialize the kernel and call nsh_main().
nsh_main() will execute NuttShell(NSH).
nx_start() is NuttX standard function, but the behavior depends on some kernel configurations.
For example, the calling nsh_main() is also configurable.

The premise of this list : NuttX12.4.0, cxd56xx, non-SMP and Flat build.
I found following kernel configurations by analyzing the boot sequence.
I think it is good to consider them,
although almost of them might be set as default.

Porting to the BCM2711 (Raspberry Pi 4B)
========================================
This port was completed for the 12.7.0 version of the NuttX kernel, and was contributed by Matteo Golin.
The pull request with this initial support can be found at `apache/nuttx/pull/15188
<https://github.com/apache/nuttx/pull/15188>`_.
The port required support to be written for a new chip (the BCM2711) and a new board. Matteo created journal entries
while working on the initial port, which can be found `on his blog
<https://linguini1.github.io/blog/2024/12/25/nuttx-bcm2711.html>`_. The details below are a more concise summary of the
porting process.
Researching
-----------
The first step to porting a board to NuttX was researching the board and how NuttX works.
The BCM2711 is a quad-core ARM Cortex A72 based SoC, and it supports both aarch64 and 32 bit ARM architectures. I
focused on the aarch64 implementation only in this port. My first step was determining other boards already in the NuttX
kernel that used the aarch64 architecture, because that gives me a starting point to porting this new chip and board.
I primarily used the blog posts written by Lup Yuen Lee about porting NuttX to the PinePhone, another ARM Cortex-A based
device. The articles are listed `here <https://github.com/lupyuen/pinephone-nuttx>`_. Lup's articles provided me with an
understanding of the NuttX boot process, as well as which files from the aarch64 support on NuttX were pulled into the
build process for booting. He also showed how he created an initial UART driver using the NuttX structure for UART
drivers, which allowed him to get NSH appearing in the console.
Finally, I also of course needed the BCM2711 datasheet in order to figure out which registers were available to me for
creating peripheral drivers. The BCM2711 datasheet isn't exceptionally detailed on many of the features on the SoC, but
it did provide enough detail to set up interrupts and get UART working.
Adding to the source tree
-------------------------
In order to build my code with the NuttX build system, I would have to add the board and the BCM2711 chip to the source
tree for NuttX. This way, it would appear as an available configuration via the ``tools/configure.sh`` script and I
could select options for it with ``make menuconfig``.
The first thing to do was to add the chip, which goes under the ``arch/arm64`` directory because it is an ARM 64 bit
SoC. The chip directory must be added in two places: ``arch/arm64/include/bcm2711`` and ``arch/arm64/src/bcm2711``. C
files go in the ``src`` directory with some header files, and some specific header files go in the ``include``
directory.
In addition, in order to make the BCM2711 visible as a supported chip, I had to add it as an option in
``arch/arm64/Kconfig``. In order to do this, I just copy-pasted the entry for the Allwinner A64, since the two chips
were very similar. I had to change a few fields (for instance, selecting ``ARCH_CORTEX_A72`` instead of
``ARCH_CORTEX_A53``), but this was relatively simple to complete with the information about the SoC. I also needed to
specify ``ARMV8A_HAVE_GICv2``, since that is the interrupt controller used by the BCM2711. ``ARCH_HAVE_MULTICPU``
because it is a quad-core, and ``ARCH_USE_MMU`` because it has a memory management unit.
I also needed to now add the Raspberry Pi 4B board to the source tree. To do this, I copied the board folder for the
PinePhone (``boards/arm64/a64/pinephone``) and renamed it ``raspberrypi-4b``. I also deleted many of the files in this
folder since they weren't applicable to the Pi 4B, and substituted all mentions of the PinePhone with the Raspberry Pi
4B (in path names and header include guards).
I then added the Pi 4B to the list of supported boards in ``boards/Kconfig``. For this, I just needed to create an entry
with the name ``ARCH_BOARD_RASPBERRYPI_4B`` and write that it depends on the ``ARCH_CHIP_BCM2711``. No additional
options necessary! In two other places in this file I also had to add some directives to make sure the Kconfig for the
board was found properly. These set ``ARCH_BOARD`` to the name of the board directory "raspberrypi-4b" when the Pi 4B was
selected, and ``source``'d the Kconfig under ``boards/arm64/bcm2711/raspberrypi-4b`` when selected.
The default configuration for this board was copied from the PinePhone's NSH configuration, which I modified to use the
correct board name, chip, and hardware specific settings. It was still incomplete because there was no code to actually
boot into NSH, but it was a starting point.
This was basically all I needed for the board to show up as a possible configuration in the source tree!
Mapping out the chip
--------------------
To start writing code for the BCM2711, I needed to map out the chip. This included the register addresses and the memory
mapping, which could all be found in the BCM2711 datasheet. From looking at other implementations, the register
addresses are usually defined as C macros and kept in header files under ``arch/<architecture>/src/<chip>/hardware``.
This is where I put them as well, defining all the register mappings the different groups within individual files (i.e.
``bmc2711_i2c.h``, ``bcm2711_spi.h``, etc.).
Many peripherals had groupings of memory-mapped registers, defined using a base address and then offsets from that
address to access the different fields. For instance, the two mini-SPI peripherals had the same structure, each with 12
registers. The way I commonly saw these macros implemented was something like:
.. code-block:: c
#define BCM_AUX_SPI1_BASEADDR (BCM_AUX_BASEADDR + BCM_AUX_SPI1_OFFSET)
#define BCM_AUX_SPI_CNTL0_REG_OFFSET (0x00) /* SPI control register 0 */
/* ... more register offsets */
/* This allows you to choose which SPI interface base address to get the register for. */
#define BCM_AUX_SPI_CNTL0(base) ((base) + BCM_AUX_SPI_CNTL0_REG_OFFSET)
In addition to the registers themselves, I also included macros to mask certain fields within the registers or set
certain values. This makes the code less error prone later, because any mistakes made while copying the long list of
fields and registers from the datasheet can be changed in one place.
.. code-block:: c
#define BCM_SPI_CNTL0_EN (1 << 11) /* Enable SPI interface */
In addition to the registers, I also had to map the interrupts. This was done in ``include/bcm2711/irq.h``. I copied the
IRQ numbers from the datasheet and listed them all as macros with names. I also had to define the number of IRQS, which
was 216 in this case. The ``MPID_TO_CORE(mpid)`` macro was copied from another arm64 implementation.
.. code-block:: c
#define NR_IRQS 216
#define MPID_TO_CORE(mpid) (((mpid) >> MPIDR_AFF0_SHIFT) & MPIDR_AFFLVL_MASK)
/* VideoCore interrupts */
#define BCM_IRQ_VC_BASE 96
#define BCM_IRQ_VC(n) (BCM_IRQ_VC_BASE + n)
#define BCM_IRQ_VC_TIMER0 BCM_IRQ_VC(0)
#define BCM_IRQ_VC_TIMER1 BCM_IRQ_VC(1)
/* More interrupts ... */
Finally was to define the memory mapping within the ``include/bcm2711/chip.h`` file. I did so simply since I was only
testing on the 4GB version of the BCM2711. The RAM starts at address 0, and is roughly 4GB in size. 64 MB of that is
reserved for the memory-mapped I/O, so I had to be sure to remove that. I also defined the load address of the kernel in
memory for the chip.
.. code-block:: c
#define CONFIG_RAMBANK1_ADDR (0x000000000)
/* Both the 4GB and 8GB ram variants use all the size in RAMBANK1 */
#if defined(CONFIG_RPI4B_RAM_4GB) || defined(CONFIG_RPI4B_RAM_8GB)
#define CONFIG_RAMBANK1_SIZE GB(4) - MB(64)
#endif /* defined(CONFIG_RPI4B_RAM_4GB) || defined(CONFIG_RPI4B_RAM_8GB) */
/* Raspberry Pi 4B loads NuttX at this address */
#define CONFIG_LOAD_BASE 0x480000
The same load address had to be specified in the linker script for the Raspberry Pi 4B kernel. This scripts tells the
compiler how to lay out the kernel code in memory and what addresses to use. I was able to copy it from the PinePhone
and just change the load address to ``0x480000``.
Figuring out the boot
---------------------
The first thing I wanted to do was determine how much work had already been done for aarch64 that would allow me to more
easily complete the port. In Lup's blogs, he tested out support for his core type (ARM Cortex-A53 on the PinePhone) by
booting the aarch64 instance of QEMU with NuttX using that core. I decided to take the same approach, and was able to
successfully boot on ARM Cortex-A72 using QEMU following his blog. This was a nice confirmation that the hardware I was
using was already supported in NuttX for booting the OS and getting NSH working with a PL011 UART interface.
I cannot stress enough that the reason porting to this chip was made so much easier was because I am standing on the
shoulders of giants. NuttX contributors had already set up the boot scripts written in assembly, timer configuration,
interrupt handling and drivers for a lot of the standard features in aarch64 architectures. I did not have to deal with
any of this because of them, and it really cut down on the amount of assembly I had to read and understand. I also
barely had to write any assembly outside of debugging the boot process a little (we'll get to that later). Not to
mention I had Lup's well-written articles to guide me.
In order to compile and boot the board, I had to add a definition for ``g_mmu_config``, which I was confused about and
left empty initially just to get past the compilation stage. I also defined the ``GICR_OFFSET`` and ``GICR_BASE`` macros
for the GICv2 interrupt controller by copying them from the Allwinner chip, which used the same controller. After
reading further in Lup's blog, I learned that the boot script has a ``PRINT`` macro which is called early in the boot
process, and requires an implementation of ``up_lowputc`` to print to the console. This would be the first thing I need
to implement. This compiled, but when I booted the Pi, nothing happened.
After quite a while of trying different things and looking at other implementations, I noticed that many people were
using register manipulation directly in the early print functions. I decided I would do the same, but instead of
printing (a more complex operation), I would turn one of the GPIO pins high. I was able to measure this with my
multimeter and confirm that the GPIO did get set, so I knew that the ``arm64_earlyprint_init`` function was getting
called. Something was wrong with my UART configuration.
I then tried directly manipulating registers to put the text "hi" in the UART FIFO. When I booted again, this printed,
but then was followed by some garbled output. It appeared that the the ``char *`` pointer passed to the print function
was getting garbled. After troubleshooting by printing characters directly by calling my ``arm64_lowputc`` in the
assembly boot script, I discovered that I could print a string from the C definition if I declared the string as static.
I also investigated the elf generated by building and confirmed the string was located in ``.rodata``. I was suspicious
that I was loading the kernel incorrectly into memory and some addresses were getting mixed up. Sure enough, I had
defined the load address in the linker script as ``0x80000`` instead of ``0x480000``. Fixing this allowed me to see the
boot messages properly!
I received this message in the console:
.. code-block:: console

I had accidentally kept the GICv3 in my config files when copying things from other boards, and changed it to GICv2.
That resolved the issue and presented me with a new one:
.. code-block:: console

After enabling all of the debug output in the build options, this became:
.. code-block:: console

print_ec_cause: SError interrupt
This looked like an unhandled interrupt, and after narrowing down which line was failing by adding log statements to the
kernel code, I discovered it was due to the spinlock code. An exception was being caused by the ``ldaxr`` instruction,
which the ARM documentation said could only be used once the MMU was enabled. I then enabled the MMU as well as its
debug information and was greeted with the lovely error:

Some more debugging allowed me to determine that the ``CONFIG_RAM_START`` and ``CONFIG_RAM_SIZE`` macros in the
defconfig for my nsh configuration were still set to the values from the PinePhone that I copied from. I set these to
the correct values for the Raspberry Pi 4B and got much further!

We actually got into tasks now! It appears stdin failed to open because in my Mini-UART driver implementation I had the
``attach`` and ``ioctl`` functions return ``-ENOSYS``. Just changing this to 0 for success in the interim allowed us to
get even further, and I could see the beginnings of NSH spawning.

It seemed like we were waiting on an interrupt which never occurred. This was weird, because my Mini-UART driver had an
interrupt implementation and appeared to be written just fine. This took hours of debugging, logging from interrupt
handlers and dumping register values, but eventually I determined that the BCM2711 datasheet actually had an error where
the TX and RX interrupt fields were swapped in the datasheet. A blog post online had mentioned this for the BCM2835, but
it appeared to be an issue on this chip as well. Now we were booting into NSH!
It was at this point that the port is considered a success, since I was able to boot into NSH and successfully run the
``ostest`` benchmark. I went on to write the start of a few more drivers, like the GPIO driver, but this completed the
requirements for an initial port and is most of what ended up being submitted in the initial pull request.

The case of ARM CM4 & cxd32xx @NuttX12.4.0
==========================================
Step1 : Add the SoC
-------------------
Create the SoC directory.
.. code-block::
$ touch arch/arm/include/cxd32xx
$ touch arch/arm/src/cxd32xx
Modify "arch/arm/Kconfig" to register the SoC directory.
Add "Kconfig" and "Make.defs" for the SoC directory.
.. code-block::
$ touch arch/arm/src/cxd32xx/Kconfig
$ touch arch/arm/src/cxd32xx/Make.defs
For details about these files, see `apache/nuttx/pull/12441`_
Step2 : Add the Board
---------------------
There are two ways about adding the Board directory.
The one is in-of-tree, another one is out-of-tree.
For details see :doc:`/guides/customboards`.
And if you wanted to add own apps, see :doc:`/guides/customapps`.
This time, the way of out-of-tree is selected.
The directory structure is following :
.. code-block::
apps/
nuttx/
out-of-tree/cxd32xx_boards
Create the board : cb2sdb2 as the board of cxd32xx.
.. code-block::
$ touch out-of-tree/cxd32xx_boards/cb2sdb2/configs/nsh
$ touch out-of-tree/cxd32xx_boards/cb2sdb2/include
$ touch out-of-tree/cxd32xx_boards/cb2sdb2/scripts
$ touch out-of-tree/cxd32xx_boards/cb2sdb2/src
Add "Kconfig", "defconfig", "Make.defs" and "Makefile".
.. code-block::
$ touch out-of-tree/cxd32xx_boards/cb2sdb2/Kconfig
$ touch out-of-tree/cxd32xx_boards/cb2sdb2/configs/nsh/defconfig
$ touch out-of-tree/cxd32xx_boards/cb2sdb2/scripts/Make.defs
$ touch out-of-tree/cxd32xx_boards/cb2sdb2/src/Makefile
For details about these files, see :ref:`out-of-tree`.
Step3 : Configure
-----------------
Now you can do configure by following commands.
It is important to confirm these commands are working.
.. code-block::
$ cd nuttx
$ ./tools/configure.sh -l ../out-of-tree/cxd32xx_boards/cb2sdb2/configs/nsh
And you can do menuconfig by following command.
.. code-block::
$ make menuconfig
And you can do distclean by following command.
.. code-block::
$ make distclean
Step4 : Compile
---------------
Try to build with the implementation of Step1-2, you would face the error as following
if you implemented only directory / Kconfig / Make.defs / Makefile / defconfig about Step1-2.
.. code-block::
$ make
Create version.h

clock_initialize.ddc] Error 1
make[1]: *** [Makefile:71: .depend] Error 2
make: *** [tools/Unix.mk:619: pass2dep] Error 2
Try to add "irq.h" with referring to cxd56xx and retry to build.
This time, the build system will teach that you have to implement "chip.h" as following.
.. code-block::
$ make
CC: clock/clock_initialize.c In file included from
/home/lassdk/workdir/nuttx2/nuttx/include/arch/armv7-m/irq.h:37:0,

compilation terminated.
make[1]: *** [Makefile:61: clock_initialize.o] Error 1
make: *** [tools/LibTargets.mk:65: sched/libsched.a] Error 2
Continue this try and error until pass the Compiling.
Step5 : Link
------------
After the pass of Compiling, you will get following error.
To resolve this error, you have to implement the linker script.
.. code-block::
$ make
make[1]: *** No rule to make target
'/home/lassdk/workdir/nuttx1/nuttx/../cxd32xx_boards/cb2sdb2/scripts/cb2sdb2.ld',
needed by '/home/lassdk/workdir/nuttx1/nuttx/../cxd32xx_boards/cb2sdb2/scripts/cb2sdb2.ld.tmp'.
Stop.
make: *** [tools/Unix.mk:545: nuttx] Error 2
Try to add the linker script with referring to some board(cxd56xx, lpc43xx, etc) or :ref:`out-of-tree`
and retry to build, the build system will teach that you have to implement some symbols as following.
.. code-block::
$ make
CPP: /home/lassdk/workdir/nuttx1/nuttx/../cxd32xx_boards/cb2sdb2/scripts/cb2sdb2.ld->
/home/lassdk/workdir/nuttx1/nuttx/../boarLD: nuttx

make[1]: *** [Makefile:197: nuttx] Error 1
make: *** [tools/Unix.mk:545: nuttx] Error 2
Step6 : Implement
-----------------
There are some implementation items, major items are bellow listed. To pass the Linking,
try to implement these symbols.
+-----------------+------------------------+--------------------------------------------------------------------+
| Category | Item | Comment |
+-----------------+------------------------+--------------------------------------------------------------------+
| SoC directory | entory point : __start | `apache/nuttx/pull/12441`_ |
+ +------------------------+ +
| | Serial Driver | |
+ +------------------------+ +
| | IDLE task stack | |
+ +------------------------+ +
| | INTC | |
+ +------------------------+ +
| | Timer | |
+-----------------+------------------------+------------------------------------------------+-------------------+
| Board directory | board_app_initialize | :doc:`/applications/nsh/customizing` |:ref:`out-of-tree` |
+ +------------------------+------------------------------------------------+ |
| |<arch>_board_initialize | `sched/Kconfig`_ :BOARD_<EARLY/LATE>_INITIALIZE| |
+-----------------+------------------------+------------------------------------------------+-------------------+
.. _apache/nuttx/pull/12441: https://github.com/apache/nuttx/pull/12441
.. _sched/Kconfig: https://github.com/apache/nuttx/blob/master/sched/Kconfig
If got the pass of Linking, you would see following result.
.. code-block::
$ make
Create version.h
LN: platform/board to /home/lassdk/workdir/nuttx2/apps/platform/dummy
Register: nsh
Register: sh
CPP: /home/lassdk/workdir/nuttx2/nuttx/../boards/cb2sdb2/scripts/cb2sdb2.ld->
/home/lassdk/workdir/nuttx2/nuttx/../boarLD: nuttx
Step7 : Verify
--------------
To execute and debug on the evaluation board, add following configurations.
.. code-block::
CONFIG_RAW_BINARY=y
CONFIG_DEBUG_SYMBOLS=y
If your implementations were good, you would see following logs.
.. code-block::
NuttShell (NSH) NuttX-12.4.0
nsh>
nsh>
nsh>
After confirming to boot NuttShell(NSH), try to execute "apps/testing/ostest".
The "apps/testing/ostest" needs following configurations.
.. code-block::
CONFIG_BUILTIN=y
CONFIG_NSH_BUILTIN_APPS=y
CONFIG_SCHED_WAITPID=y
CONFIG_TESTING_OSTEST=y
And one more test is recommended to check the timer implementation whether
the kernel could count the time accurately or not.
I checked it by following code. About the function : cxd32_timerget(),
see `apache/nuttx/pull/12441`_
.. code-block::
extern uint32_t cxd32_timerget(void);
{
uint32_t pre;
uint32_t post;
pre = cxd32_timerget();
sleep(1);
post = cxd32_timerget();
printf("pre:%lu post:%lu exptect:1sec\n", pre, post);
pre = cxd32_timerget();
sleep(10);
post = cxd32_timerget();
printf("pre:%lu post:%lu exptect:10sec\n", pre, post);
}

=======================
RAM Disks and ROM Disks
=======================
.. warning::
Migrated from:
https://cwiki.apache.org/confluence/display/NUTTX/RAM+Disks+and+ROM+Disks
NSH mkrd Command
================
The typical way to create a RAM disk is by using the NuttShell (NSH) ``mkrd``
command. The syntax is:
.. code-block:: shell
mkrd [-m <minor>] [-s <sector-size>] <nsectors>
This command creates a RAM disk consisting of ``<nsectors>`` sectors, each of
size ``<sector-size>`` (or 512 bytes if ``<sector-size>`` is not specified). The
RAM disk is then registered as ``/dev/ram<minor>``. If ``<minor>`` is not
specified, ``mkrd`` attempts to register the RAM disk as ``/dev/ram0``.
Internally, the NSH ``mkrd`` command is a simple wrapper around the OS
``boardctl()`` interface, using the ``BOARDIOC_MKRD`` command. “Under the hood,”
this ``boardctl()`` command performs the following:
1. Allocates kernel-space memory with ``kmm_malloc()`` of size ``<nsectors>``
times ``<sector-size>``
2. Zeros the allocated memory, and
3. Calls the OS-internal function ``ramdisk_register()`` to create the RAM disk.
NSH ROMFS /etc Support
======================
A ROM disk is a block device created from a read-only file system image stored
in FLASH or other ROM. There is no NSH command available to create a ROM disk
at runtime. However, it is possible to enable ROM disk support in NSH using the
``CONFIG_NSH_ROMFSETC`` option, as described in the section on NSH start-up
scripts in the `NSH User Guide <https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=139629410>`_.
Any application is able to create a ROM disk using the ``boardctl()`` interface
with the ``BOARDIOC_ROMDISK`` command.
Creating RAM Disks in Board Bring-Up Logic
==========================================
RAM disks may be created in board-specific initialization logic that runs in
supervisor mode. That logic might look as follows:
.. code-block:: c
int board_ramdisk(int minor, unsigned int sectsize, unsigned int nsectors)
{
size_t allocsize = (size_t)sectsize * (size_t)nsectors;
FAR uint8_t *buffer;
/* Allocate the memory backing up the ramdisk */
buffer = (FAR uint8_t *)kmm_zalloc(allocsize);
if (buffer == NULL)
{
return -ENOMEM;
}
/* Then register the ramdisk */
ret = ramdisk_register(minor, buffer, nsectors, sectsize,
RDFLAG_WRENABLED | RDFLAG_FUNLINK);
if (ret < 0)
{
kmm_free(buffer);
}
return ret;
}
Alternatively, this could be replaced by a call to the OS internal function
``mkrd()``.
Creating ROM Disks in Board Bring-Up Logic
==========================================
.. note::
Currently, the ``romdisk_register()`` function is only available within the
OS. Certain logic in ``apps/`` directly calls ``romdisk_register()``, which
violates the portable POSIX OS interface. The correct approach for an
application is to create a ROM disk via ``boardctl(BOARDIOC_ROMDISK)`` as
described above. Calling ``romdisk_register()`` directly is not only a
violation of the NuttX portable interface, but also is not allowed in
PROTECTED or KERNEL build modes.
ROM disks, i.e., read-only disks in FLASH, can be created by board bring-up
logic in a way similar to RAM disks, with the following caveats:
- The FLASH region is not allocated; the FLASH address, the sector size, and the
number of sectors must already be known.
- The ``romdisk_register()`` function is used instead of ``ramdisk_register()``.
A simple example could look like:
.. code-block:: c
int board_romdisk(int minor, FAR uint8_t *buffer, unsigned int sectsize,
unsigned int nsectors)
{
/* Register the romdisk */
return romdisk_register(minor, buffer, nsectors, sectsize);
}
Calling ``romdisk_register()`` is equivalent to calling ``ramdisk_register()``
with the final parameter ``flags == 0``.
Most ROM disks use the ROMFS file system, although CROMFS is another option.
Creating ROMFS file system images involves several steps. Tools are available
to simplify the process of building ROMFS images, but that topic is outside the
scope of this Wiki page.

====================
Reading CAN Messages
====================
.. warning::
Migrated from:
https://cwiki.apache.org/confluence/display/NUTTX/Reading+CAN+Messages
Twice now, there have been complaints or issues about reading messages from the
CAN driver. The usual concern is that the driver is somehow losing or dropping
CAN messages. In these cases, it is often discovered that the CAN driver is
being used incorrectly and, as is human nature, the driver itself is blamed for
the problem.
When reading from the CAN driver, multiple messages may be returned, depending
on two factors:
1. The size of the returned CAN messages.
2. The size of the buffer provided to receive CAN messages.
It should never be assumed that a single message will be returned; making this
assumption can lead to lost CAN messages under conditions in which the read
buffer can hold more than one small message. The following example shows how to
properly handle the CAN read operation:
.. code-block:: c
#define BUFLEN 128 /* Some arbitrary size for the CAN RX buffer */
FAR struct can_msg_s *msg;
char rxbuffer[BUFLEN];
ssize_t nread;
int nbytes;
int msglen
int i;
/* Read messages into the RX buffer */
nread = read(fd, rxbuffer, BUFLEN);
/* Check for read errors */
...
/* Process each message in the RX buffer */
for (i = 0; i <= nread - CAN_MSGLEN(0); i += msglen)
{
/* Get the next message from the RX buffer */
msg = (FAR struct can_msg_s *)&rxbuffer[i];
nbytes = can_dlc2bytes(msg->cm_hdr.ch_dlc);
msglen = CAN_MSGLEN(nbytes);
DEBUGASSERT(i + msglen < BUFLEN);
/* Process the next CAN message */
...
}
By looping over the read buffer and parsing out each CAN message, it is
possible to avoid losing messages that are stored contiguously in the input
buffer.

Removing Device Drivers with NSH
================================
.. warning::
Migrated from:
https://cwiki.apache.org/confluence/display/NUTTX/Removing+Device+Drivers+with+NSH
NuttX and Unix-like Operating Systems Compared
==============================================
There are many things that are called device drivers. In this context, the
discussion is limited to **character device drivers**. In NuttX, character
device drivers are represented by device driver nodes in the top-level :doc:`pseudo
filesystem </components/filesystem/pseudofs>`.
Standard Unix-like operating systems also support device driver nodes, which
superficially resemble NuttX device driver nodes: Both look like files and
usually reside under the top-level ``/dev`` directory. Both can be accessed
with standard POSIX file system commands such as ``open()``, ``close()``,
``read()``, ``write()``, and so forth. However, the similarity ends there.
The payload of a standard Unix-like operating system device driver node is a
device major and minor number. These major and minor device numbers are used to
look up the actual device driver interface using internal OS logic and data
structures. A NuttX device node, by contrast, directly holds the device driver
interface with no intervening lookup. This design is less flexible, but it is
more efficient and conserves limited resources in an embedded system.
In standard Unix-like operating systems, the device node can simply be deleted
using the shell command ``rm`` or the programmatic interface ``unlink()``. The
node is removed, and nothing special happens to the underlying device driver
(except that it may no longer be accessible).
In NuttX, if the device node were removed in the same way, the entire device
interface would also be removed, effectively breaking the driver. Internally,
NuttX supports a function called ``unregister_driver()`` that can be invoked
to remove a device driver. Therefore, removing the device driver node must
behave as though ``unregister_driver()`` were called.
The unlink() Method
===================
How is this accomplished in NuttX? It is done via a special device driver
method called ``unlink()``.
NuttX device drivers are implemented via a vtable of function pointers. That
vtable defines the interface between the pseudo-file system and the device
driver. This vtable is the structure ``struct file_operations`` defined in
``[nuttx]/include/nuttx/fs/fs.h``. It provides several interfaces that closely
match the standard POSIX interfaces—``open()``, ``close()``, ``read()``,
``write()``, etc.—and also includes a method called ``unlink()``. This
``unlink()`` method is called by the NuttX VFS when a user removes a device
driver node.
.. note::
Removal of device driver nodes is only permitted if
``CONFIG_DISABLE_PSEUDOFS_OPERATIONS`` is **not** defined. All pseudo-file
system operations may be suppressed to reduce the FLASH footprint in systems
with extremely limited resources.
Removing a Device Node from NSH
===============================
Below is a summary of what happens when a device node is deleted using the NSH
``rm`` command:
1. The user enters the ``rm`` command. The NSH parser recognizes the command
and transfers control to the NSH function ``cmd_rm()``.
2. ``cmd_rm()`` verifies the command, then calls the standard POSIX
``unlink()`` interface. The logic in the VFS ``unlink()`` function in
``[nuttx]/fs/vfs/fs_unlink.c`` is then executed.
3. The VFS ``unlink()`` detects that the target to be removed is a device node
in the top-level pseudo-file system. It calls the device driver's
``unlink()`` method. It also removes the device node from the
pseudo-filesystem. However, the underlying resources required to support
the device driver interface may remain until the device driver frees those
resources.
4. When the device driver's ``unlink()`` method is called, it determines if
the device resources can be freed immediately. If so, it frees those
resources. If, for example, there are still open references to the device
driver, it may defer freeing the resources until the last client has closed
the device driver and there are no open references. In such a case, it may
set a flag indicating that the device driver has been unlinked.
5. If freeing of device driver resources has been deferred, that flag will be
examined later. For instance, when the last client of the device driver
closes its reference to the driver, it checks whether the unlink operation
was deferred. If so, it frees any remaining device driver resources at that
time.
.. warning::
Some character device driver instances do not implement the ``unlink()``
method. If problems arise when attempting to remove character drivers as
described in this Wiki page, a missing ``unlink()`` method is the most
likely cause.

===============
Rust in NuttX
===============
.. warning::
This guide is under development. Rust support in NuttX is experimental.
Introduction
============
NuttX is exploring Rust integration to provide memory safety guarantees and modern
language features while maintaining its small footprint and real-time capabilities.
This guide covers:
- Setting up Rust toolchain for NuttX development
- Building Rust components with NuttX
- Interoperability between Rust and C
- Testing Rust components
Prerequisites
=============
- Rust toolchain installed (rustup recommended)
- NuttX build environment configured
- Basic knowledge of Rust and NuttX development
Supported Platforms
===================
- AArch64 (WIP)
- ARMv7-A (WIP)
- ARMv6-M
- ARMv7-M
- ARMv8-M
- RISCV32
- RISCV64
Getting Started
===============
1. Install Rust toolchain and switch to nightly
Please refer to the official Rust installation guide for more details: https://www.rust-lang.org/tools/install
.. code-block:: bash
rustup toolchain install nightly
rustup default nightly
2. Prepare NuttX build environment
Please ensure that you have a working NuttX build environment, and with the following PR merged or cherry-picked:
- https://github.com/apache/nuttx-apps/pull/2487
- https://github.com/apache/nuttx/pull/15469
3. Enable essential kernel configurations
Pleae enable the following configurations in your NuttX configuration:
- CONFIG_SYSTEM_TIME64
- CONFIG_FS_LARGEFILE
- CONFIG_TLS_NELEM = 16
- CONFIG_DEV_URANDOM
The `rv-virt:nsh` board using make as the build system is recommended for testing Rust applications as it has been verified to work with this configuration.
For `rv-virt:nsh` board, you should disable `CONFIG_ARCH_FPU` configuration since RISCV32 with FPU is not supported yet.
4. Enable sample application

Migrated from:

You can enhance the functionality of your released embedded system by adding
ELF programs, which can be loaded from a file system. These programs can be
stored on an SD card or downloaded into on-board SPI FLASH, allowing for
easy updates or extensions to the system's firmware.
There are two ways you can accomplish this:
Partially linked
================
This describes building the partially linked, relocatable ELF program that
depends on a symbol table provided by the base firmware in FLASH.
Reference:
- See :doc:`Partially Linked ELF Programs <partially_linked_elf>`
Fully linked

This describes building a fully linked, relocatable ELF program that does
not depend on any symbol table information.

==============
Kernel threads are really like tasks except that they run inside the operating
system and are started with ``kernel_thread()`` which is prototyped in
system and are started with ``kthread_create()`` which is prototyped in
``include/nuttx/kthread.h``. The differ from tasks in that (1) in PROTECTED and
KERNEL builds, they have full supervisor privileges, and (2) they have full
access to all internal OS resources.
In order to build the task into the OS as a kernel thread, you simply have to:
(1) place the kernel thread code in your board source code directory, and (2)
start it with ``kernel_thread()`` in your board bring-up logic. There a few
start it with ``kthread_create()`` in your board bring-up logic. There a few
examples of this in the NuttX source tree. Here is one:

So that is another trick that you can use to architecture optimal solutions:
Create parts of your applications as kernel threads: They need to reside in
your board/src directory and the need to be started with ``kernel_thread()`` in
your board/src directory and the need to be started with ``kthread_create()`` in
your board bring-up logic. And that is it.

IMX95LPD5EVK-19
===============
The IMX95LPD5EVK-19 board is a platform designed to show the most commonly
used features of the
`i.MX 95 automotive applications processor
<https://www.nxp.com/products/iMX95>`_ .
Features
========
- Multicore Processing [1]_
- 1x Arm Cortex-M7
- 6x Arm Cortex-A55 multicore complex
- 1x Arm Cortex-M33
- Memory
- On-Chip Memory
- 1376kB SRAM (ECC)
- External Memory
- Up to 6.4GT/s x32 LPDDR5/LPDDR4X (with Inline ECC & Inline Encrpytion)
- 1x Octal SPI, including support for SPI NOR and SPI NAND memories
- Connectivity
- CAN FD
- UART/USART/Profibus, I²C, SPI
- Messaging Units (MU) to support IPC between heterogeneous cores
.. [1] NuttX is currently supported exclusively on the Cortex-M7 core of the
i.MX95
Serial Console
==============
The IMX95LPD5EVK-19 board features a high-speed USB-to-UART/MPSSE device,
FT4232H (U70) that provides a debug interface for the i.MX95 processor through
the USB type-C connector (J31). The device acts as a bridge to enable
communication between the target processor and the host computer, which
connects to the USB connector (J31) through a USB cable.
Channel A is used as UART port to provide USB-to-UART option for debugging the
Arm Cortex-M7 core of the i.MX 95 processor (default option).
J-Link External Debug Probe
===========================
The IMX95LPD5EVK-19 board provides a 2x5-pin Samtec FTSH-105-01-L-DV-K header
(J30) for connecting a JTAG debugger (external JTAG) for debugging the i.MX95
processor. The FT4234H JTAG provides the remote debug option for the i.MX95
processor.
Firmware location
=================
Instruction Tightly Coupled Memory (ITCM)
-----------------------------------------
The purpose of the Tightly-Coupled Memory (TCM) is to provide low-latency
memory that the processor can use without the unpredictability that is a
feature of caches. By default the firmware will be located in this area
(256K).
DDR
---
DDR memory can be used in case the code memory footprint becomes bigger than
the ITCM size. Using this configuration implies that other cores should be
aware of this.
For the default sd-card image from the EVK, these adaptations are needed on
the software running on the M33 and A55 cores.
- `System Manager <https://github.com/nxp-imx/imx-sm>`_ (M33) should give
the M7 access to the DDR region
- `linux-imx <https://github.com/nxp-imx/linux-imx>`_ (A55) should reserve
the DDR region by specifying it in the device tree so linux won't make
use of it
Configurations
==============
All the configurations can be used in combination with the default sd-card
image that is shipped with the EVK.
nsh
---
Configures the NuttShell (nsh) located at examples/nsh. This NSH
configuration is focused on low level, command-line driver testing. Built-in
applications are supported, but none are enabled. This configuration does not
support a network.
can
---
Configures the NuttShell (nsh) and also adds CAN support. CAN1 is enabled and
can be accessed at J17 on the EVK. Make sure that SW9[3] (PDM_CAN_SEL) is set
to ON. The configuration includes CAN utilities as candump and cansend.
.. note::
`System Manager <https://github.com/nxp-imx/imx-sm>`_ (M33) should give
the M7 access rights to the PIN_PDM_CLK (CAN1_TX) and
PIN_PDM_BIT_STREAM0 (CAN1_RX) pins in the mx95evk.cfg.
Alternatively these can be set manually in the system manager's console:
.. code-block:: console
>$ mm 0x443c01e0 0x6
>$ mm 0x443c01e4 0x6
rpmsg
-----
This configuration is similar to nsh but in addition it offers the Remote
Processing Messaging (RPMsg) service to enable heterogeneous inter-core
communication. A virtual UART (CONFIG_RPMSG_UART) is made available on which
an OS running on the A55 cores can connect. There is also an option to use
the filesystem client feature in which a remote directory can be mounted to
a local directory (CONFIG_FS_RPMSGFS).
.. note::
`linux-imx <https://github.com/nxp-imx/linux-imx>`_ (A55) needs the
NuttX compatible rpmsg_tty and rpmsg_fs drivers. See `dev mailing list
<https://www.mail-archive.com/dev@nuttx.apache.org/msg12112.html>`_

ARM64 Toolchain
===============
Before building NuttX for the Raspberry Pi 4B, download the ARM64 Toolchain for
**AArch64 Bare-Metal Target** ``aarch64-none-elf`` from
`Arm GNU Toolchain Downloads <https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads>`_.
(Skip the section for Beta Releases.)
Add the downloaded toolchain ``gcc-arm-...-aarch64-none-elf/bin`` to the ``PATH`` Environment Variable.
If you are running Arch Linux, you can also get the toolchain by installing from the AUR:
.. code:: console
$ yay -S aarch64-none-elf-gcc-bin aarch64-none-elf-toolchain
Check the ARM64 Toolchain:
.. code:: console
$ aarch64-none-elf-gcc -v
Building
========
To build NuttX for the Raspberry Pi 4B, :doc:`install the prerequisites </quickstart/install>` and :doc:`clone the git
repositories </quickstart/install>` for ``nuttx`` and ``apps``.
Configure the NuttX project to use the Raspberry Pi 4B and build it (this example uses the ``nsh`` configuration).
.. code:: console
$ cd nutxx
$ tools/configure.sh raspberrypi-4b:nsh
$ make
Booting
========
In order to boot NuttX on the Raspberry Pi 4B, you will need to have a formatted micro SD card. The SD card should
contain a FAT32 partition that is marked as bootable and which contains the generated ``nuttx.bin`` and ``config.txt``
files from the build process. In addition to those files, you will also need the following files from the Raspberry Pi
repository for loading the image:
- `bcm2711-rpi-4-b.dtb <https://github.com/raspberrypi/firmware/blob/stable/boot/bcm2711-rpi-4-b.dtb>`_
- `fixup4.dat <https://github.com/raspberrypi/firmware/blob/stable/boot/fixup4.dat>`_
- `fixup4cd.dat <https://github.com/raspberrypi/firmware/blob/stable/boot/fixup4cd.dat>`_
- `fixup4db.dat <https://github.com/raspberrypi/firmware/blob/stable/boot/fixup4db.dat>`_
- `fixup4x.dat <https://github.com/raspberrypi/firmware/blob/stable/boot/fixup4x.dat>`_
- `start4.elf <https://github.com/raspberrypi/firmware/blob/stable/boot/start4.elf>`_
- `start4cd.elf <https://github.com/raspberrypi/firmware/blob/stable/boot/start4cd.elf>`_
- `start4db.elf <https://github.com/raspberrypi/firmware/blob/stable/boot/start4db.elf>`_
- `start4x.elf <https://github.com/raspberrypi/firmware/blob/stable/boot/start4x.elf>`_
You can download all of these files with the shell script in ``tools/bcm2711/bootfiles.sh``.
SD Card Formatting
------------------
Here is a list of ``fdisk`` commands for formatting the SD card on Linux. The tutorial assumes the SD card is at
``/dev/sda``, but you can find the location of your SD card with ``lsblk``. **Make very sure you verify that the name is
correct, or you can lose data by formatting a different device.**
.. code:: console
$ sudo fdisk /dev/sda
Print the partition table on the card with ``p`` to see what's there. If anything appears, continue to use the ``d``
command to remove all partitions.
- ``o`` to create a new, empty DOS partition table
- ``n`` to create a new partition
- ``p`` to make it primary
- Hit enter to select the default partition of "1"
- Hit enter for the default start and end sizes, which will use the full SD card size
- ``t`` to change the type of the partition (hit enter to select default of partition 1)
- ``c`` as the type, which is for Windows FAT32
- ``a`` to mark the partition as bootable
- ``w`` to write all the changes and save
Now when you run ``lsblk``, you should see ``/dev/sda1`` (or an equivalent for your SD card). That is the new partition
just created. Running the following command will then format the SD card to an empty FAT32 file system.
.. code:: console
$ sudo mkfs.vfat /dev/sda1
Once this completes, you can copy all of the aforementioned boot files, ``nuttx.bin`` and ``config.txt`` to your SD card
in your preferred way (through a file explorer or by using ``mount``).
Once all the files are copied, you can then eject the SD card and insert it onto your Raspberry Pi. The default console
is the Mini UART, which requires an adapter such as `USB to TTL serial converter cable
<https://www.adafruit.com/product/954>`_ to read. You should connect the ground to one of the Pi's ground pins, and then
connect the RX to GPIO 14 and TX to GPIO 15. **Do not connect the red power wire**.
Once the converter is connected and plugged into your host computer, you can open up a serial terminal of your choice. I
use Minicom. Then, power your Raspberry Pi 4B with a USB-C cable and wait for the Pi to boot and the NSH prompt to
appear onscreen:

efuse
-----
This configuration demonstrates the use of the eFuse driver. It can be accessed
through the ``/dev/efuse`` device file.
Virtual eFuse mode can be used by enabling `CONFIG_ESPRESSIF_EFUSE_VIRTUAL`
option to prevent possible damages on chip.
The following snippet demonstrates how to read MAC address:
.. code-block:: C
int fd;
int ret;
uint8_t mac[6];
struct efuse_param_s param;
struct efuse_desc_s mac_addr =
{
.bit_offset = 1,
.bit_count = 48
};
const efuse_desc_t* desc[] =
{
&mac_addr,
NULL
};
param.field = desc;
param.size = 48;
param.data = mac;
fd = open("/dev/efuse", O_RDONLY);
ret = ioctl(fd, EFUSEIOC_READ_FIELD, &param);
To find offset and count variables for related eFuse,
please refer to Espressif's Technical Reference Manuals.

---help---
Use the BASEPRI register to enable and disable interrupts. By
default, the PRIMASK register is used for this purpose. This
usually results in hardfaults when supervisor calls are made.
Though, these hardfaults are properly handled by the RTOS, the
hardfaults can confuse some debuggers. With the BASEPRI
register, these hardfaults, will be avoided. For more details see
https://cwiki.apache.org/confluence/display/NUTTX/ARMv7-M+Hardfaults%2C+SVCALL%2C+and+Debuggers
WARNING: If CONFIG_ARCH_HIPRI_INTERRUPT is selected, then you
MUST select CONFIG_ARMV7M_USEBASEPRI. The Kconfig dependencies
here will permit to select an invalid configuration because it
