Development Environment
^^^^^^^^^^^^^^^^^^^^^^^
Either Linux or Cygwin on Windows can be used for the development environment.
The source has been built only using the GNU toolchain (see below). Other
toolchains will likely cause problems. Testing was performed using the Cygwin
environment.
GNU Toolchain Options
^^^^^^^^^^^^^^^^^^^^^
The NuttX make system has been modified to support the following different
toolchain options.
1. The Code Red GNU toolchain
2. The CodeSourcery GNU toolchain,
3. The devkitARM GNU toolchain,
4. The NuttX buildroot Toolchain (see below).
All testing has been conducted using the Code Red toolchain and the
make system is setup to default to use the Code Red Linux toolchain. To use
the other toolchain, you simply need add one of the following configuration
options to your .config (or defconfig) file:
CONFIG_LPC17_CODESOURCERYW=y : CodeSourcery under Windows
CONFIG_LPC17_CODESOURCERYL=y : CodeSourcery under Linux
CONFIG_LPC17_DEVKITARM=y : devkitARM under Windows
CONFIG_LPC17_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
CONFIG_LPC17_CODEREDW=n : Code Red toolchain under Windows
CONFIG_LPC17_CODEREDL=y : Code Red toolchain under Linux
You may also have to modify the PATH in the setenv.h file if your make cannot
find the tools.
NOTE: the CodeSourcery (for Windows), devkitARM, and Code Red (for Windoes)
are Windows native toolchains. The CodeSourcey (for Linux), Code Red (for Linux)
and NuttX buildroot toolchains are Cygwin and/or Linux native toolchains. There
are several limitations to using a Windows based toolchain in a Cygwin
environment. The three biggest are:
1. The Windows toolchain cannot follow Cygwin paths. Path conversions are
performed automatically in the Cygwin makefiles using the 'cygpath' utility
but you might easily find some new path problems. If so, check out 'cygpath -w'
2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic links
are used in Nuttx (e.g., include/arch). The make system works around these
problems for the Windows tools by copying directories instead of linking them.
But this can also cause some confusion for you: For example, you may edit
a file in a "linked" directory and find that your changes had no effect.
That is because you are building the copy of the file in the "fake" symbolic
directory. If you use a Windows toolchain, you should get in the habit of
making like this:
make clean_context all
An alias in your .bashrc file might make that less painful.
3. Dependencies are not made when using Windows versions of the GCC. This is
because the dependencies are generated using Windows pathes which do not
work with the Cygwin make.
Support has been added for making dependencies with the windows-native toolchains.
That support can be enabled by modifying your Make.defs file as follows:
- MKDEP = $(TOPDIR)/tools/mknulldeps.sh
+ MKDEP = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
If you have problems with the dependency build (for example, if you are not
building on C:), then you may need to modify tools/mkdeps.sh
NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
level of -Os (See Make.defs). It will work with -O0, -O1, or -O2, but not with
-Os.
NOTE 2: The devkitARM toolchain includes a version of MSYS make. Make sure that
the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
path or will get the wrong version of make.
NuttX buildroot Toolchain
^^^^^^^^^^^^^^^^^^^^^^^^^
A GNU GCC-based toolchain is assumed. The files */setenv.sh should
be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
different from the default in your PATH variable).
If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
SourceForge download site (https://sourceforge.net/projects/nuttx/files/).
This GNU toolchain builds and executes in the Linux or Cygwin environment.
1. You must have already configured Nuttx in <some-dir>/nuttx.
cd tools
./configure.sh zkit-arm-1769/<sub-dir>
2. Download the latest buildroot package into <some-dir>
3. unpack the buildroot tarball. The resulting directory may
have versioning information on it like buildroot-x.y.z. If so,
rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
4. cd <some-dir>/buildroot
5. cp configs/cortexm3-defconfig-4.3.3 .config
6. make oldconfig
7. make
8. Edit setenv.h, if necessary, so that the PATH variable includes
the path to the newly built binaries.
See the file configs/README.txt in the buildroot source tree. That has more
detailed PLUS some special instructions that you will need to follow if you
are building a Cortex-M3 toolchain for Cygwin under Windows.
NOTE: The cortexm3-defconfig-4.3.3 produces an older-style is OABI toolchain.
There is another configuration, cortexm3-eabi-defconfig-4.6.3, that will
build a newer, EABI, toolchain. Unfortunately, the 4.6.3 EABI toolchain is
not compatible with the NXFLAT tools. See the top-level TODO file (under
"Binary loaders") for more information about this problem. If you plan to
use NXFLAT, please do not use the GCC 4.6.3 EABI toochain; instead use the
GCC 4.3.3 OABI toolchain.
NXFLAT Toolchain
^^^^^^^^^^^^^^^^
If you are *not* using the NuttX buildroot toolchain and you want to use
the NXFLAT tools, then you will still have to build a portion of the buildroot
tools -- just the NXFLAT tools. The buildroot with the NXFLAT tools can
be downloaded from the NuttX SourceForge download site
(https://sourceforge.net/projects/nuttx/files/).
This GNU toolchain builds and executes in the Linux or Cygwin environment.
1. You must have already configured Nuttx in <some-dir>/nuttx.
cd tools
./configure.sh zkit-arm-1769/<sub-dir>
2. Download the latest buildroot package into <some-dir>
3. unpack the buildroot tarball. The resulting directory may
have versioning information on it like buildroot-x.y.z. If so,
rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
4. cd <some-dir>/buildroot
5. cp configs/cortexm3-defconfig-nxflat .config
6. make oldconfig
7. make
8. Edit setenv.h, if necessary, so that the PATH variable includes
the path to the newly builtNXFLAT binaries.
LEDs
^^^^
If CONFIG_ARCH_LEDS is defined, then support for the ZKit-ARM LEDs will be
included in the build. See:
- configs/zkit-arm-1769/include/board.h - Defines LED constants, types and
prototypes the LED interface functions.
- configs/zkit-arm-1769/src/zkitarm_internal.h - GPIO settings for the LEDs.
- configs/zkit-arm-1769/src/up_leds.c - LED control logic.
The ZKit-ARM LPC1768 has a single LEDs (there are more on the Embedded Artists
base board, but those are not controlled by NuttX). Usage this single LED by NuttX
is as follows:
- The LED is not illuminated until the ZKit-ARM completes initialization.
If the LED is stuck in the OFF state, this means that the ZKit-ARM did not
complete intialization.
- Each time the OS enters an interrupt (or a signal) it will turn the LED OFF and
restores its previous stated upon return from the interrupt (or signal).
The normal state, after initialization will be a dull glow. The brightness of
the glow will be inversely related to the proportion of time spent within interrupt
handling logic. The glow may decrease in brightness when the system is very
busy handling device interrupts and increase in brightness as the system becomes
idle.
Stuck in the OFF state suggests that that the system never completed
initialization; Stuck in the ON state would indicated that the system
intialialized, but is not takint interrupts.
- If a fatal assertion or a fatal unhandled exception occurs, the LED will flash
strongly as a slow, 2Hz rate.
ZKit-ARM Configuration Options
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
General Architecture Settings:
CONFIG_ARCH - Identifies the arch/ subdirectory. This should
be set to:
CONFIG_ARCH=arm
CONFIG_ARCH_family - For use in C code:
CONFIG_ARCH_ARM=y
CONFIG_ARCH_architecture - For use in C code:
CONFIG_ARCH_CORTEXM3=y
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
CONFIG_ARCH_CHIP=lpc17xx
CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
chip:
CONFIG_ARCH_CHIP_LPC1768=y
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
hence, the board that supports the particular chip or SoC.
CONFIG_ARCH_BOARD=zkit-arm-1769
CONFIG_ARCH_BOARD_name - For use in C code
CONFIG_ARCH_BOARD_ZKITARM=y
CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
of delay loops
CONFIG_ENDIAN_BIG - define if big endian (default is little
endian)
CONFIG_DRAM_SIZE - Describes the installed DRAM (CPU SRAM in this case):
CONFIG_DRAM_SIZE=(32*1024) (32Kb)
There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
CONFIG_DRAM_START - The start address of installed DRAM
CONFIG_DRAM_START=0x10000000
CONFIG_ARCH_IRQPRIO - The LPC17xx supports interrupt prioritization
CONFIG_ARCH_IRQPRIO=y
CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
have LEDs
CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
stack. If defined, this symbol is the size of the interrupt
stack in bytes. If not defined, the user task stacks will be
used during interrupt handling.
CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to board architecture.
CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
cause a 100 second delay during boot-up. This 100 second delay
serves no purpose other than it allows you to calibratre
CONFIG_ARCH_LOOPSPERMSEC. You simply use a stop watch to measure
the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
the delay actually is 100 seconds.

Configurations
^^^^^^^^^^^^^^
Each ZKit-ARM configuration is maintained in a sudirectory and can be
selected as follow:
cd tools
./configure.sh zkit-arm-1769/<subdir>
cd -
. ./setenv.sh
Where <subdir> is one of the following:
hello:
This builds an example application using apps/examples/hello. See
apps/examples/README.txt for information about the examples.
thttpd:
This builds the THTTPD web server example using the THTTPD and
the apps/examples/thttpd application.
NOTE: You will need to build the NXFLAT toolchain as described
above in order to use this example.

* must be provided by board-specific logic. They are implementations of the select
* and status methods of the SPI interface defined by struct spi_ops_s (see
* include/nuttx/spi.h). All other methods (including up_spiinitialize())
* are provided by common LPC17xx logic. To use this common SPI logic on your
* board:
*
* 1. Provide logic in lpc17_boardinitialize() to configure SPI/SSP chip select
* pins.
* 2. Provide lpc17_ssp0/ssp1select() and lpc17_ssp0/ssp1status() functions
* in your board-specific logic. These functions will perform chip selection
* and status operations using GPIOs in the way your board is configured.
* 3. Add a calls to up_spiinitialize() in your low level application
* initialization logic
* 4. The handle returned by up_spiinitialize() may then be used to bind the
* SPI driver to higher level logic (e.g., calling
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
* the SPI MMC/SD driver).
