+drivers. The form of the interface was inspired by the Linux Gadget APIs.
+
+At present USB device controller drivers are included for:
+* The NXP LPC214x. This driver has been verified and is an early alpha
+stage in quality.
+* TI DM320. Coding for this driver is complete but it is completely
+untested as of this release.
+
+A controller-independent class driver is also included for:
+* USB serial class device driver (emulates the Prolific PL2303
+serial-to-USB adapter). This driver has only been verified with
+the Linux host PL2303 driver.
+
+Other new features include:
+* Add an option to set aside a separate stack for interrupt
+handling (ARM only). This is useful when memory is constrained,
+there are multiple tasks, and the interrupt stack requirement
+is high (as when USB is enabled).
+
+A few bugs were also fixed:
+* Fixed the frequency of system timer interrupts in the NXP LPC214x port
+(off by 20x in nuttx-0.3.15)
+* Fixed serial driver bugs related to (1) open counts and (2) recognizing
+O_NONBLOCK on read.
+* Fixed an error in read(); it was not setting the errno on errors returned

+STR-P711 board.
+* The Hitachi SH-1 using the SH1_LCEVB1 (SH-1/US7032EVB1) board

+
+* A loop device that converts a file into a block device.
+* A block to character (BCH) driver that allow access a block device as
+if it were character device.
+* Added strcasecmp() and strncasecmp() libc functions.
+* Added the 'dd' and 'losetup' commands to NSH. These commands
+(along with mkfatfs and mount), give good management of filesystems
+on the target.
+
+Several bugs were fixed, the most important of which are:
+
+* Fixed a race condition workaround delay in LPC214X SPI logic.
+This was also the cause of some bad MMC/SD performance on that
+platform.
+
+* Fixed a recently introduced FAT file system problem: It would

+* Corrected two other important errors in the FAT lseek() implementation:
+1 - The sectors-per-cluster value was being reset to "1".
+2 - Important lseek logic was omitted when the seek position was zero.

+is under development but not ready for check-in yet.
+* Added support for fixed precision math.
+* Added support for outgoing multicast packets.
+
+Several bugs were fixed, the most important of which are:
+
+* Fixed an important bug in the TCP/IP buffering logic. When
+TCP/IP read-ahead is enabled and not recv() is in-place when a
+TCP/IP packet is received, the packet is placed into a read-ahead
+buffer. However, the old contents of the read-ahead buffer
+were not being cleared and old data would contaminate the newly

+This is the 15th release of NuttX and the 4th release containing
+the integration of a network subsystem and the uIP TCP/IP, UDP, and
+ICMP stacks into NuttX (see http://www.sics.se/~adam/uip/index.php/Main_Page).
+
+Many network-related problems have been fixed and the implementation
+has matured significantly. This release consists of:
+
+o TCP-related bug-fixes for disconnecting sockets
+o Correction of some TCP read-ahead logic
+o TCP performance improvements
+o Misc. additions and cleanup (See the ChangeLog for a complete list of
+changes).
+
+The level of network reliability is at an early beta release level. The
+baseline functionality of NuttX continues to mature and remains at
+post-beta. Open network-related issues include only:
+
+o Some minor unimplemented BSD socket functionality,
+o Thread safety issues: the same socket cannot be used concurrently on
+different threads.
+o Pending design changes necessary to support multiple network interfaces.
+o IPv6 support is incomplete.
+
+This release has been verified only on the Neuros OSD (DM320 ARM9)
+platform using the DM90x0 driver. Any feedback for improving the network
+reliability/performance would be greatly appreciated.

+preliminary port of NuttX to the ZiLOG z16f 16-bit microcontroller.
+This port was verified using the ZiLOG z16f2800100zcog Development
+and the ZiLOG ZDS-II toolchain. See http://www.zilog.com for
+further information.
+
+I emphasize that this is a preliminary release of the z16f port and
+is only alpha or, perhaps, pre-alpha quality as of this writing.
+There are a list of known issues in the TODO file in the root of
+the NuttX directory. The overall quality of NuttX (excluding the
+z16f port) continues to improve beyond the late beta level.
+
+The z16f port required numerous changes to NuttX to handle:
+
+* NEAR and FAR addressing, and
+* Use of a Windows native toolchain in a Cygwin build environment.
+
+In addition to the z16f port, at least one very critical bug was
+found and corrected in NuttX: The thread-specific errno value of one
+task was being randomly trashed when a different thread exited.
+
+This release were verified on the ZiLOG z16f2800100zcog, Neuros OSD

+(https://nuttx.apache.org/docs/latest/components/nxflat.html)
+
+A standard CGI interface is used: Information is pasted to the CGI
+program via POST commands and via environment variables. CGI socket
+I/O is redirected to stdin and stdout so that the CGI program only
+need to printf() to send its content back to the HTTP client.
+
+Another value to this THTTPD integration effort has been that THTTPD
+has provided a very good test bed for finding NuttX networking bugs.
+Several very critical networking bugs have been fixed with this
+0.4.11 release (see the ChangeLog for details). Networking throughput
+has also been greatly improved. Anyone using NuttX networking

+## Changes to Build System
+
+### Change CFLAGS, CPPFLAGS, CXXFLAGS, and AFLAGS from Recursive to Simple Assignment
+
+[PR-1890](https://github.com/apache/nuttx/pull/1890)
+(commit [2caf3a69e3d60ec550980f7ba897c732e7a39df7](https://github.com/apache/nuttx/pull/1890/commits/2caf3a69e3d60ec550980f7ba897c732e7a39df7))
+attempts to speed up compilation time for concurrent builds by changing
+assignment to makefile variables `*CFLAGS*`, `*CPPFLAGS*`, `*CXXFLAGS*`, and
+`*AFLAGS*` from recursive `=` to simple `:=`. This causes these compile
+options to be expanded only once during the build.
+
+If you are using NuttX on a custom board not in the NuttX repository, you may
+want to make a similar change to your `Make.defs` files. Change these
+recursive assignments:
+
+```
+CFLAGS = $(ARCHCFLAGS) $(ARCHWARNINGS) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe
+CXXFLAGS = $(ARCHCXXFLAGS) $(ARCHWARNINGSXX) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHXXINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe
+CPPFLAGS = $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS)
+AFLAGS = $(CFLAGS) -D__ASSEMBLY__
+```
+
+to simple assignments:
+
+```
+CFLAGS := $(ARCHCFLAGS) $(ARCHWARNINGS) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe
+CXXFLAGS := $(ARCHCXXFLAGS) $(ARCHWARNINGSXX) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHXXINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe
+CPPFLAGS := $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS)
+AFLAGS := $(CFLAGS) -D__ASSEMBLY__
+```
+
+### Not Necessary to Define `__NuttX__` in Make.defs
+
+[PR-2192](https://github.com/apache/nuttx/pull/2192)
+(commit [9208176f600d0d04446531909bf05710716a5ee4](https://github.com/apache/nuttx/commit/9208176f600d0d04446531909bf05710716a5ee4))
+refactors definition of the `__NuttX__` preprocessor symbol to
+`tools/Config.mk`, so it is no longer necessary to define it in each board's
+`Make.defs` file.
+
+If you are using NuttX on a custom board not in the NuttX repository, you may
+want to make a similar change to your Make.defs files.
+
+Remove lines like this:
+
+```
+ARCHDEFINES = -D__NuttX__
+```
+
+Or remove -D__NuttX__ from lines like this:
+
+```
+CXXFLAGS += $(ARCHDEFINES) $(EXTRAFLAGS) -pipe -std=c++11 -D__NuttX__
+```

+# Security Issues Fixed In This Release
+
+# Compatibility Concerns
+
+## Changes to Kconfig
+
+The names of some Kconfig settings have been changed to improve the naming consistency. Here is the list:
+
+| Old| New |
+|:------------------:| -----------------:|
+|LIB_BOARDCTL|BOARDCTL |
+|LIB_CRC64_FAST|LIBC_CRC64_FAST|
+|LIB_ENVPATH |LIBC_ENVPATH |
+|LIB_HEX2BIN |LIBC_HEX2BIN |
+|LIB_HOMEDIR |LIBC_HOMEDIR |
+|LIB_HOSTNAME|LIBC_HOSTNAME|
+|LIB_KBDCODEC|LIBC_KBDCODEC|
+|LIB_RAND_ORDER|LIBC_RAND_ORDER|
+|LIB_SLCDCODEC |LIBC_SLCDCODEC |
+|LIB_USRWORK |LIBC_USRWORK |
+|LIB_USRWORKPRIORITY |LIBC_USRWORKPRIORITY |
+|LIB_USRWORKSTACKSIZE|LIBC_USRWORKSTACKSIZE|
+|LIB_ZONEINFO|LIBC_ZONEINFO|
+|LIB_ZONEINFO_ROMFS|LIBC_ZONEINFO_ROMFS|
+
+When they appear in code, these identifiers begin with a `CONFIG_*` prefix (e.g., `CONFIG_LIB_BOARDCTL` is renamed to `CONFIG_BOARDCTL`).
+
+All in-tree boards have been updated, but users who maintain their own out-of-tree boards will have to update all instances of these identifiers.
+
+See PR-4266 https://github.com/apache/nuttx/pull/4266 and PR-4267 https://github.com/apache/nuttx/pull/4267 in the main NuttX repository.
+
+See also PR-820 https://github.com/apache/nuttx-apps/pull/820 and PR-821 https://github.com/apache/nuttx-apps/pull/821 in the NuttX apps repository.
+
+## Changes to MTD subsystem
+
+MTDIOC_XIPBASE, MTDIOC_FLUSH and MTDIOC_PARTINFO is removed and replace with BIOC_XIPBASE, BIOC_FLUSH and BIOC_PARTINFO:
+
+* Simplify the general driver(e.g. partition, flt) implementation
+* Reduce the confusion with the same IOCTL in the different layer
+
+See PR-4325 https://github.com/apache/nuttx/pull/4325
+
+## Changes to Build System
+
+### LD Now Called Through GCC
+
+When building NuttX with GCC toolchains, the linker is now called through $(CROSSDEV)gcc rather than $(CROSSDEV)ld. This requires all linker options to be prefixed with `-Wl,` (dash, capital W, lower-case L, comma). All boards in the NuttX tree have been updated, but any custom out-of-tree boards will need to apply this change in the relevant parts of their build scripts.
+
+The reason for this change is that GNU Binutils 2.36.x has added new error checking on command line arguments. This has had the effect that the NuttX build suddenly broke on host OS distributions that updated to the 2.36.x release line. Reports included Arch, Manjaro, and Ubuntu. Other host OSes are likely to be affected as well.
+
+#### Symptoms
+
+Your toolchain and board are affected if you see errors from LD like:
+
+```
+arm-none-eabi-ld: Error: unable to disambiguate: -nostartfiles (did you mean --nostartfiles ?)
+```
+
+or (following this change in NuttX) errors from GCC like:
+
+```
+arm-none-eabi-gcc: error: unrecognized command line option '--gc-sections'; did you mean '--data-sections'?
+```
+
+#### What to change
+
+The most common change expected to affect most boards:
+
+Change:
+
+```
+NXFLATLDFLAGS1 = -r -d -warn-common
+NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-pcrel.ld -no-check-sections
+```
+
+to:
+
+```
+NXFLATLDFLAGS1 = -r -Wl,-d -Wl,-warn-common
+NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-pcrel.ld -Wl,-no-check-sections
+```
+
+If doing a kernel build, you may need changes in your board's `kernel/Makefile` like:
+
+Change:
+
+```
+USER_LDFLAGS = --undefined=$(ENTRYPT) --entry=$(ENTRYPT) $(USER_LDSCRIPT)
+```
+
+to:
+
+```
+USER_LDFLAGS = -Wl,--undefined=$(ENTRYPT) -Wl,--entry=$(ENTRYPT) $(USER_LDSCRIPT) -nostartfiles -nodefaultlibs
+```
+
+Change:
+
+```
+$(Q) $(LD) -o $@ $(USER_LDFLAGS) $(USER_LIBPATHS) $(OBJS) --start-group $(USER_LDLIBS) --end-group $(USER_LIBGCC)
+```
+
+to:
+
+```
+$(Q) $(LD) -o $@ $(USER_LDFLAGS) $(USER_LIBPATHS) $(OBJS) -Wl,--start-group $(USER_LDLIBS) -Wl,--end-group $(USER_LIBGCC)
+```
+
+Depending on your board's customized build scripts, you may need to look out for other `make` variables in your board's `Makefile` or `Make.defs`.
+
+Some variables to look for:
+
+- `ARCHSCRIPT`
+- `ARCH_LIBS`
+- `CCLINKFLAGS`
+- `EXTRALINKCMDS`
+- `LDELFFLAGS`
+- `LDENDGROUP`
+- `LDFLAGS`
+- `LDLINKFLAGS`
+- `LDMODULEFLAGS`
+- `LDSTARTGROUP`
+- `NXFLATLDFLAGS1`
+- `NXFLATLDFLAGS2`
+- `USER_LDFLAGS`
+
+Anything that executes LD, such as:
+
+```
+$(Q) $(LD) --entry=__start $(LDFLAGS) $(LIBPATHS) $(EXTRA_LIBPATHS) \
+```
+
+Anything that processes LD flags, such as:
+
+```
+$(LIBPATHS) "-(" $(LDLIBS) "-)" $(LDFLAGS) -Map="$(TOPDIR)$(DELIM)nuttx.map"
+```
+
+In general, any command line options destined for LD must be prefixed with `-Wl,` (dash, capital W, lower-case L, comma) since they are now being passed through GCC.
+
+#### Examples
+
+Change:
+
+```
+EXTRALINKCMDS += @$(TOPDIR)/syscall/syscall_wraps.ldcmd
+```
+
+to:
+
+```
+EXTRALINKCMDS += -Wl,@$(TOPDIR)/syscall/syscall_wraps.ldcmd
+```
+
+Change:
+
+```
+LDFLAGS += -gc-sections
+```
+
+to:
+
+```
+LDFLAGS += -Wl,-gc-sections
+```
+
+Change:
+
+```
+$(LIBPATHS) "-(" $(LDLIBS) "-)" $(LDFLAGS) -Map="$(TOPDIR)$(DELIM)nuttx.map"
+```
+
+to:
+
+```
+$(LIBPATHS) "-(" $(LDLIBS) "-)" $(LDFLAGS) -Wl,-Map="$(TOPDIR)$(DELIM)nuttx.map"
+```
+
+Change:
+
+```
+NXFLATLDFLAGS1 = -r -d -warn-common
+```
+
+to:
+
+```
+NXFLATLDFLAGS1 = -r -Wl,-d -Wl,-warn-common
+```
+
+Change:
+
+```
+ifeq ($(CONFIG_CYGWIN_WINTOOL),y)
+LDFLAGS += -Map="${shell cygpath -w $(TOPDIR)/nuttx.map}" --cref
+else
+LDFLAGS += -Map=$(TOPDIR)/nuttx.map --cref
+endif
+```
+
+to:
+
+```
+ifeq ($(CONFIG_CYGWIN_WINTOOL),y)
+LDFLAGS += -Wl,-Map="${shell cygpath -w $(TOPDIR)/nuttx.map}" -Wl,--cref
+else
+LDFLAGS += -Wl,-Map=$(TOPDIR)/nuttx.map -Wl,--cref
+endif
+```
+
+Also, if you have assigned the LD variable, it would need to change as well:
+
+Change:
+
+```
+LD = $(CROSSDEV)ld
+```
+
+to:
+
+```
+LD = $(CROSSDEV)gcc
+```

+Compatibility Concerns
+
+#6276 - Remove -nostartfiles and -nodefaultlibs from individual board Make.defs.
+
+#6256 - Remove ARCHWARNINGS = -Wall -Wstrict-prototypes -Wshadow -Wundef and ARCHWARNINGSXX = -Wall -Wshadow -Wundef and then remove ARCHWARNINGS and ARCHWARNINGSXX from CFLAGS and CXXFLAGS.
+
+#5897 - Remove -fno-exceptions -fcheck-new from ARCHCFLAGS and ARCHCXXFLAGS and change ARCHCFLAGS = to ARCHCFLAGS += and ARCHCXXFLAGS = to ARCHCXXFLAGS +=. C++ exceptions are now managed centrally by Kconfig options CONFIG_CXX_EXCEPTION and CONFIG_CXX_RTTI.
+
+#6144 - Remove from each board:
+
+ifeq ($(CONFIG_DEBUG_SYMBOLS),y)
+ARCHOPTIMIZATION = -g
+endif
+
+and
+
+ifeq ($(CONFIG_DEBUG_SYMBOLS),y)
+LDFLAGS += -g
+endif
+
+as these are now managed centrally by Kconfig option CONFIG_DEBUG_SYMBOLS.
+
+#6155 - Remove from each board:
+
+ifneq ($(CONFIG_DEBUG_NOOPT),y)
+ARCHOPTIMIZATION += $(MAXOPTIMIZATION) -fno-strict-aliasing
+endif
+
+as these are now managed centrally by Kconfig options CONFIG_DEBUG_OPTLEVEL and CONFIG_DEBUG_FULLOPT.

+## Security Issues Fixed In This Release
+## Compatibility Concerns
+## API Changes
+Default Semaphore Protocol Changed
+
+When NuttX is built with priority inheritance (CONFIG_PRIORITY_INHERITANCE), priority inheritance can be enabled or disabled per semaphore and care must be taken to make the correct choice based on how each semaphore is used.
+
+When a semaphore is used as a mutual exclusion lock ("locking semaphore"), a thread that needs exclusive access to a resource waits on the semaphore, uses the resource, and then posts the semaphore. In this case, priority inheritance should be enabled for the semaphore (sem_setprotocol(sem, SEM_PRIO_INHERIT)) to mitigate priority inversion which could occur when multiple threads with different priorities compete for various resources.
+
+In contrast, when a semaphore is used to signal an event from one thread to another ("signaling semaphore"), one thread waits on the semaphore and another thread posts it when the anticipated event occurs. In this case, since the thread that posts the semaphore is different than the one that waits on it, priority inheritance must not be enabled for the semaphore (sem_setprotocol(sem, SEM_PRIO_NONE)).
+
+In earlier releases, priority inheritance was enabled by default for all semaphores whenever NuttX was built with CONFIG_PRIORITY_INHERITANCE. If a semaphore was used for signaling across threads, the non-standard API sem_setprotocol(sem, SEM_PRIO_NONE) had to be used to selectively disable priority inheritance for that semaphore.
+
+Starting with this release, the default is changed: priority inheritance is disabled by default for all semaphores. To enable priority inheritance for a semaphore, first NuttX needs to be built with CONFIG_PRIORITY_INHERITANCE, then priority inheritance needs to be enabled for the semaphore in question with sem_setprotocol(sem, SEM_PRIO_INHERIT).
+
+The benefit of this change is easier porting and maintenance of standards-compliant applications to NuttX by eliminating the need for 3rd party applications to call the non-standard API sem_setprotocol().
+
+In addition, this is a safer default: Having priority inheritance inadvertently enabled for a signaling semaphore can cause incorrect behavior, while the impact of having it inadvertently disabled for a locking semaphore is limited to reduced performance.
+
+This change was introduced in PR # 5070 https://github.com/apache/incubator-nuttx/pull/5070, git commits 4e1d967bcd0031bd07a6a46f022c75216cf98404, e5fbbd416d5f1e74e3f705677b2e99b0b8c544d3, 9a4b66fbb306d388e2ce431807a139848604a9f0, and 125de66b63b316a2c2a2912dd408f4bac2fc85c3.
+
+All semaphore uses within the NuttX repositories have been updated; those used for locking have been replaced with mutexes (mutex_t instead of sem_t). See PR # 6965, git commits 
+
+ef3919e4eb75b1ab854a21c98124d7e90e5c5e14, 590e0d5666c47dcb91ccd35faa57681ca26d4b1d, and 5db565c78d7c009eaea8517f01a2d138ab5f0028.
+
+Downstream users need to call sem_setprotocol(sem, SEM_PRIO_INHERIT) when setting up each semaphore used for mutual exclusion locking. In addition, they may optionally remove calls to sem_setprotocol(sem, SEM_PRIO_NONE) for signaling semaphores.

+
+Compatibility Concerns
+* [#8166](https://github.com/apache/nuttx/pull/8166) ESP32: Enable the allocation of Userspace heap exclusively in SPI RAM under Flat mode 
+
+Breaking change: ESP32_SPIRAM no longer auto selects XTENSA_IMEM_USE_SEPARATE_HEAP.
+XTENSA_IMEM_USE_SEPARATE_HEAP is now selected by ESP32_IMM_HEAP, which in turn is not enabled by default.
+
+Drivers that previously relied on XTENSA_IMEM_USE_SEPARATE_HEAP now bring in ESP32_IMM_HEAP if ESP32_SPIRAM is also selected, with the notable exception from ESP32_WIFI.
+
+ESP32_WIFI previously used XTENSA_IMEM_USE_SEPARATE_HEAP for allocating dynamic data into Internal RAM via a specific API.
+With this PR, there is now an alternative approach using MM_KERNEL_HEAP. So it is up to the user to either select ESP32_IMM_HEAP or MM_KERNEL_HEAP.
+In order to keep the current behavior, custom board users shall select ESP32_IMM_HEAP on Kconfig.  
+
+* [#7525](https://github.com/apache/nuttx/pull/7525) Improvements in TCP connections allocation.
+
+This is an attempt to fix the issues reported in #6960:
+
+Only a single connection is allocated, the one actually needed.
+In tcp_free() the connection is actually deallocated, instead of leaving it existing forever in the list.
+
+This is only the first step, possibly with more to come (list of pre-allocated connections, maximum connections limit etc).
+
+For the moment, this PR handles only TCP, till we determine all the details.
+Then the fix will be copied to all other connections that use similar logic.
+
+* [#8691](https://github.com/apache/nuttx/pull/8691) drivers/serial: Echo input in driver layer
+* [#8846](https://github.com/apache/nuttx/pull/8846) drivers/pty: Echo input by default
+
+Align the pty behavior to linux/bsd,
+Also fix the ECHO issue with microadb after #8691.
+adb shell will echo normally with this patch.
+
+* [#8235](https://github.com/apache/nuttx/pull/8235) board: Pass the assertion expression to board_crashdump too
+
+* [#8717](https://github.com/apache/nuttx/pull/8717) arch/armv8-m: DSP extension is optional
+The DSP extension is optional for armv8-m cores, so it should be explicitly set by chip configuration.
+Otherwise this can lead to hard to debug hardfaults for cores that do not support DSP.
+Breaking change for out-of-tree armv8-m chips.
+
+* [#8378](https://github.com/apache/nuttx/pull/8378) tools/makefile: silent all compile output
+In order to make compilation warnings and errors easier to be found out,
+this commit will disable the printing of the compilation process as much
+as possible, and also if you want to restore the log information of the
+compilation process, please enable verbose build on command line:
+
+$ make V=0
+OR
+$ make V=1
+
+| V=0: Exit silent mode
+| V=1,2: Enable echo of commands
+| V=2: Enable bug/verbose options in tools and scripts
+
+* [#8623](https://github.com/apache/nuttx/pull/#8623) include/signal.h:Expanding SIGNAL to be consistent with Linux
+build breaks if CONFIG_SCHED_HAS_PARENT is not defined because SIGCHLD will collide with the new values.

+Compatibility Concerns
+* [#8827](https://github.com/apache/nuttx/pull/8827) arch/nrf52: nvmc and flash should depends on ALLOW_BSD_COMPONENTS=y  
+
+Users using nvmc and flash must allow BSD components (CONFIG_ALLOW_BSD_COMPONENTS=y).
+
+* [#8992](https://github.com/apache/nuttx/pull/8992) stm32: Remove GPIO_{SPEED|MODE}_xxx and provide a legacy path for lazy migration  
+
+All boards board.h should be migrated using tools/stm32_pinmap_tool.py
+`tools/stm32_pinmap_tool.py --pinmap arch/arm/src/stm32h7/hardware/stm32h7x3xx_pinmap_legacy.h --addall --suffix _0 --report /include/board.h
+it will output 2 sections that should be used to update the board.h.
+
+* [#9527](https://github.com/apache/nuttx/pull/9527) sched/tls: remove PTHREAD_CLEANUP from Kconfig  
+
+use PTHREAD_CLEANUP_STACKSIZE to enable or disable interfaces pthread_cleanup_push() and pthread_cleanup_pop().
+Same as TLS_TASK_NELEM - It is no need to use two variables. Make the reserved entries more explicit
+
+* [#8985](https://github.com/apache/nuttx/pull/8985) drivers/pipe: make pipe and named pipe (mkfifo) POSIX-compliant (blocking open)  
+
+It would be a possible breaking change if any application was written specifically to expect an open for write-only 
+(and O_NONBLOCK cleared, of course) to be non-blocking even if there are no readers.
+Being able to port POSIX-compliant applications that expect open to block when opening for write-only with no readers
+would enhance NuttX's objective of "to achieve a high degree of standards compliance. The primary governing standards 
+are POSIX and ANSI standards". That is the case for RTP Tools, for instance.

+NuttX-4.14
+----------
+
+This is the 46th release of NuttX. The release extends the support
+for the STMicro STM32 microcontroller. Minimal support for the
+STM3210E-EVAL development board based around the STM32F103ZET6 MCU
+was released in NuttX-0.4.12 and extended in NuttX-0.4.13 to include
+initial USB support. This completes the STM32F103ZET6 and adds:
+
+New Generic RTOS Features:
+
+* Added generic support that can be included in any block driver
+to provide read-ahead buffering and write buffering for improved
+driver performance.
+* Added a generic worker thread that can used to defer processing
+from an interrupt to a task.
+* Defined a generic SD/SDIO interface can can be bound to a MMC/SD
+or SDIO driver to provide SDIO support.
+* Implemented a an SDIO-based MMC/SD driver using this new SDIO
+interface.
+
+New STM32 Features:
+
+* Add support to configure an STM32 input GPIO to generate an
+EXTI interrupt.
+* Added support for buttons on the STM3210E-EVAL board.
+* Implemented an STM32 version of the common the SDIO interface.
+* Added a configuration to exercise the STM32 with the USB mass
+storage device class example.
+
+This release also corrects some important bugs in the early STM32 release:
+
+* Correct error handling in the mount() logic.
+* Fixed several STM32 DMA-related issues. Integrated and debugged
+STM32 DMA functionality that was added in 0.4.12.
+* Fixed several bugs in the STM32 USB device-side driver.
+
+NOTE: This version, 4.14, is equivalent to what would have been
+called 0.4.14 to follow 0.4.13. The zero has been eliminated from
+the front of the version number to avoid confusion about the state
+of development: Some have interpreted the leading zero to mean
+that the code is in some way unstable. That was not the intent.
+Beginning in January 2010, I will switch to the 2010.nn versioning
+as many others have done to avoid such confusion.

+NuttX-5.0
+---------
+
+This is 47th release of NuttX and the successor to nuttx-4.14. This
+major revision number has been incremented to indicate that an
+incompatibility with previous nuttx releases has been introduced.
+This version adopts standard fixed width integer names as specified
+by the ANSI C99 standard. The core logic of NuttX is older than
+that standard and did not conform to it.
+
+If you have applications running on NuttX-4.14, those applications
+should continue to build and execute without problem on NuttX-5.0.
+However, if you have device drivers or other OS-internal logic, you
+will probably have to make some minor changes to your code to use
+this version. Below is a summary of those changes:
+
+* If you include sys/types.h to get the non-standard, fixed width
+integer types (uint32, uint16, ubyte, etc.), that is no longer
+necessary.
+* Instead, you will need to include stdint.h where the new fixed
+width integer types are defined (uint32_t, uint16_t, uint8_t, etc).
+* You will have to change all occurrences of the following types:
+
+uint32 -> uint32_t
+uint16 -> uint16_t
+ubyte -> uint8_t
+uint8 -> uint8_t
+sint32 -> int32_t
+sint16 -> int16_t
+sint8 -> int8_t
+
+* In addition, the non-standard type 'boolean' must replaced with
+the standard type 'bool'. The type definition for 'bool' is in
+stdbool.h
+
+This change in typing caused small changes to many, many files. It
+was verified that all configurations in the release still build
+correctly (other than the SDCC-based configurations). Regression
+testing was performed on a few configurations, but it is possible
+that minor build issues still exist. (If you encounter any, please
+let me know and I will help you to fix them.)
+
+In the course of the regression testing, several important bugs
+unrelated to the type changes were found and corrected.
+
+* Fixed an important error in the RX FIFO handling logic of the
+LM3S6918 Ethernet driver.
+* Corrected the handling of TCP sequence numbers in the TCP stack.
+* And other less important bugs as detailed in the ChangeLog.
+
+The primary focus of this release was standards compatibility, but
+a few new features were added including a (1) Flash Translation
+Layer (FTL) that will support filesystems on a FLASH device and (2)
+partial ports for the STM32F107VC and HCS12 C9S12NE64 MCUs. Those
+ports are very incomplete as of this writing.

+NuttX-5.1
+---------
+
+This is the 48th release of NuttX. This release adds support for
+two new MCU architectures in various states of development:
+
+* AT91SAM3U (http://www.atmel.com/products/at91/sam3landing.asp?family_id=605)
+
+This release adds support for the SAM3U-EK development board with
+the AT91SAM3U4E MCU
+(http://www.atmel.com/dyn/products/product_card_mcu.asp?part_id=4562).
+As with most NuttX architecture releases, the release will be
+rolled out in two parts: A basic port and an extended port.
+
+NuttX-5.1 includes the basic port for the SAM3U-EK board. This
+release passes the NuttX OS test and is proven to have a valid
+OS implementation. It supports the basic boot-up, serial console
+and timer interrupts. A configuration to support the NuttShell
+is also included.
+
+The extended port will also include support for SDIO-based SD
+cards and USB device (and possible LCD support). These extensions
+may or may not happen by the NuttX 5.2 release as my plate is
+kind of full now.
+
+* LPC3131 (http://ics.nxp.com/products/lpc3000/lpc313x.lpc314x.lpc315x/)
+
+This release also adds the complete implementation of the basic
+port for the NXP LPC3131 MCU on the Embedded Artists EA3131 board
+(http://www.embeddedartists.com/products/kits/lpc3131_kit.php).
+That port, unfortunately has stalled due to tools issues. Those
+tool issues have been resolved and I am confident that the verified
+basic port will be available in NuttX-5.2.
+
+The extended release will follow and should include SDIO-based
+SD card support and device USB.
+
+A few additional features and bugfixes of a minor nature were also
+incorporated as detailed in the ChangeLog.

+NuttX-5.10
+----------
+
+This is the 57th release of NuttX. This release includes a combination
+of some new features as well as several bugfixes. New features
+include:
+
+* TI/Luminary Stellaris LM3S9B96:
+Header file changes contributed by Tiago Maluta.
+* TI/Luminary Stellaris LM3S8962:
+Header file changes and support for the Stellaris LM3S8962
+Ethernet+CAN Evaluation Board contributed by Larry Arnold.
+* On-Demand Paging Support:
+The basic logic for the On-Demand Paging feature is complete,
+implemented for the NXP LPC3131, and partially tested. See
+https://nuttx.apache.org/docs/latest/components/paging.html.
+Some additional test infrastructure will be needed in order to complete
+the verification. See configs/ea3131/README.txt for details.
+* Two Pass Build Support:
+The make system now supports a two pass build where a relocatable,
+partially linked object is created on the first pass and that
+object is linked with the NuttX libraries to produce the final
+executable on the second pass. This two pass build is currently
+only used to support the On-Demand paging feature: The first
+pass link forces critical logic into the locked text region;
+the second pass builds the NuttX executable more-or-less as
+normal.
+* CONFIG_APP_DIR:
+Generalized the way in which applications are built and linked
+with NuttX. The new configuration CONFIG_APP_DIR replaces
+CONFIG_EXAMPLE. CONFIG_EXAMPLE used to identify the sub-directory
+within the NuttX examples/ directory that held the example
+application to be built. That made it awkward to configure to
+build an application that resides outside of the NuttX examples/
+directory. CONFIG_APP_DIR is more general; it can be used to
+refer to any directory containing the application to be built.
+
+For people who have their own configurations and/or Makefiles,
+you will need to make a couple of changes:
+
+- Replace all occurrences of CONFIG_EXAMPLE=foobar with
+CONFIG_APP_DIR=examples/foobar in all of the configuration
+files.
+- Replace any occurrences of examples/$(CONFIG_EXAMPLE) with
+$(CONFIG_APP_DIR)
+- Replace any occurrences of lib$(CONFIG_EXAMPLE)$(LIBEXT)
+with libapp$(LIBEXT) in your Makefiles.
+- Check any other occurrences of CONFIG_EXAMPLE.
+
+* Several bugfixes are included as well as code changes to eliminate
+some warnings. See the ChangeLog for details.

+----------
+
+This is the 59th release of NuttX. This is a critical bugfix release.
+
+* Fixed an important error in the signal trampoline logic.
+Essentially, interrupts are re-enabled while the signal handler
+executes, but the logic to re-disable the interrupts before
+returning from the signal handler trampoline was missing. Under
+certain circumstances, this can cause stack corruption. This
+was discovered by David Hewson on an ARM9 platform, but since
+the code has been leveraged, the bug has been propagated from
+ARM to Cortex-M3, AVR32, M16C, SH1, ZNEO, eZ80, Z8, and Z80 --
+almost every architecture. The correction has been incorporated
+for all architectures but only verified on a few.
+
+Other notable changes in NuttX-5.12:
+
+* A complete port for the AVR32 (AT32UC3B0256) is incorporated
+in the source tree. Testing of this port is underway now. This
+release was made before verifying this port in order to get the

+* AVR32, www.mcuzone.com AVR32DEV1
+
+The port for the www.mcuzone.com AVRDEV1 board based on the
+Atmel AT32UC3B0256 MCU was (almost) fully integrated. The port
+now successfully passes the NuttX OS test (examples/ostest).
+A NuttShell (NSH) configuration is in place (see the NSH User
+Guide at https://nuttx.apache.org/docs/latest/components/nsh/index.html).
+Testing of that NSH configuration, however, has been postponed
+(because it got bumped by the Olimex LPC1766-STK port -- see below)
+
+Current Status: I think I have a hardware problem with my serial
+port setup. There is a good chance that the NSH port is complete
+and functional, but I am not yet able to demonstrate that. At
+present, I get nothing coming in the serial RXD line (probably
+because the pins are configured wrong or I have the MAX232
+connected wrong).
+
+A complete port will include drivers for additional AVR32 UC3
+devices -- like SPI and USB --- and will be available in a
+later release, time permitting.
+
+* LPC1766, Olimex LPC1766-STK
+
+Support for the Olimex-LPC1766 is newly added to NuttX and is
+still undergoing development, test, and integration. Verified
+configurations for the NuttX OS test and for the NuttShell (NSH,

+NuttX-5.14
+----------
+
+The 61st release of NuttX, NuttX-5.14, was made on November 27,
+2010. This release includes multiple, important bugfixes as well
+as a new driver for the NXP LPC1766.
+
+This release corresponds with SVN release number: r3137
+
+Important bugfixes include:
+
+* Cortex-M3 Hard Fault. Fixed a hard fault problem that can occur
+if certain types of interrupts are pending at the time another
+interrupt returns. This problem has only been observed on the
+LPC1766 (returning from a SYSTICK interrupt with a pending
+Ethernet interrupt). However, it is assumed that all Cortex-M3
+ports could have this as a latent bug.
+
+* TCP/IP Sequence Number Bug. Corrected errors some important
+logic in the way that sequence numbers are managed when send()
+sends out packets before a previous packet has been acknowledged.
+Some of that send() logic was incompatible with logic in the
+uIP layer. Errors seen include: (1) The final final packet in
+a sequence of packets might be too large! In the THTTPD example,
+this might leave some garbage at the bottom of the display. Or
+(2) send() might hang with outstanding, unacknowledged data
+(and with no re-transmission requests). This was due to
+differences in sequence number handling in send() and in
+uip_tcpinput.c; uip_tcpinput.c thought (incorrectly) that all
+of the bytes were acknowledged; send.c knew that they were not.
+
+* One-Shot POSIX Timer Bug. Fixed an error in set-up of a one-shot
+POSIX timer. It was using the repetitive timer value (which
+is zero in the one-shot case), always resulting in a 10Ms timer!
+Found and fixed by Wilton Tong.
+
+Additional support has been included for the Olimex-LPC1766. Support
+for that board was added to NuttX 5.13. This release extends that
+support with an Ethernet driver. Verified configurations are now
+available for the NuttX OS test, for the NuttShell (NSH, see
+https://nuttx.apache.org/docs/latest/components/nsh/index.html),
+for the NuttX network test, and for the THTTPD webserver.
+(Additional USB configurations are in the release as well, but those
+have not yet been verified. Goals for NuttX-5.15 (and beyond) include:
+(1) Verified USB support, (2) SD card support, and (3) LCD support.

+The 62nd release of NuttX, NuttX-5.15, was made on December 12,
+2010. This release includes several bugfixes as well as feature
+enhancements, primarily for the Olimex LPC1766-STK board.
+
+Important bugfixes included:
+
+* Additional fixes needed with the TCP sequence number problem
+"fixed" in NuttX-5.14.
+* In the send() logic, now checks if the destination IP address
+is in the ARP table before sending the packet; an ARP request
+will go out instead. This improves behavior, for example, on
+the first on the first GET request from a browser
+* All USB class drivers need to call DEV_CONNECT() when they are
+ready to be enumerated. That is, (1) initially when bound to
+the USB driver, and (2) after a USB reset.
+* The SPI_SETBITS macro was calling the SPI setmode method.
+* And several other bug fixes of lower importance (see the
+ChangeLog for details).
+
+And feature enhancements:
+
+* The LPC176x Ethernet driver was using all of AHB SRAM Bank0 for
+Ethernet packet buffers (16K). An option was added to limit
+the amount of SRAM used for packet buffering and to re-use any
+extra Bank0 memory for heap.
+
+* Enabled networking and SD/MMC card support in the Olimex
+LPC1766-STK NuttShell (NSH) configuration.
+
+* The LPC176x USB driver is now fully fully functional.
+* Added an optional cmddata() method to the SPI interface. Some
+devices require an additional out-of-band bit to specify if the
+next word sent to the device is a command or data. The cmddata
+method provides selection of command or data.
+
+* A driver for the Nokia 6100 LCD (with either the Phillips PCF8833
+LCD controller and for the Epson S1D15G10 LCD controller) and
+an NX graphics configuration for the Olimex LPC1766-STK have
+been added. However, neither the LCD driver nor the NX
+configuration have been verified as of the this release.

+----------
+
+The 63rd release of NuttX, Version 5.16, was made on January 10,
+2010 and is available for download from the SourceForge website.
+This release includes initial support for USB host in NuttX. The
+USB host infrastructure is new to NuttX. This initial USB host release
+is probably only beta quality; it is expected the some bugs remain
+in the logic and that the functionality requires extension.
+
+Below is a summary of the NuttX USB host implementation as extracted
+from the NuttX Porting Guide:
+
+6.3.9 USB Host-Side Drivers
+* include/nuttx/usb/usbhost.h. All structures and APIs needed to
+work with USB host-side drivers are provided in this header
+file.
+* struct usbhost_driver_s. Each USB host controller driver must
+implement an instance of struct usbhost_driver_s. This structure
+is defined in include/nuttx/usb/usbhost.h. Examples:
+arch/arm/src/lpc17xx/lpc17_usbhost.c.
+* struct usbhost_class_s. Each USB host class driver must implement
+an instance of struct usbhost_class_s. This structure is also
+defined in include/nuttx/usb/usbhost.h. Examples:
+drivers/usbhost/usbhost_storage.c
+* USB Host Class Driver Registry. The NuttX USB host infrastructure
+includes a registry. During its initialization, each USB host
+class driver must call the interface, usbhost_registerclass()
+in order add its interface to the registry. Later, when a USB
+device is connected, the USB host controller will look up the
+USB host class driver that is needed to support the connected
+device in this registry. Examples: drivers/usbhost/usbhost_registry.c,
+drivers/usbhost/usbhost_registerclass.c, and
+drivers/usbhost/usbhost_findclass.c,
+* Detection and Enumeration of Connected Devices. Each USB host
+device controller supports two methods that are used to detect
+and enumeration newly connected devices (and also detect
+disconnected devices):
++ int (*wait)(FAR struct usbhost_driver_s *drvr, bool connected);
+Wait for a device to be connected or disconnected.
++ int (*enumerate)(FAR struct usbhost_driver_s *drvr);
+Enumerate the connected device. As part of this enumeration
+process, the driver will (1) get the device's configuration
+descriptor, (2) extract the class ID info from the configuration
+descriptor, (3) call usbhost_findclass() to find the class
+that supports this device, (4) call the create() method on
+the struct usbhost_registry_s interface to get a class instance,
+and finally (5) call the connect() method of the struct
+usbhost_class_s interface. After that, the class is in charge
+of the sequence of operations.
+* Binding USB Host-Side Drivers. USB host-side controller drivers
+are not normally directly accessed by user code, but are usually
+bound to another, higher level USB host class driver. The class
+driver exports the standard NuttX device interface so that the
+connected USB device can be accessed just as with other, similar,
+on-board devices. For example, the USB host mass storage class
+driver (drivers/usbhost/usbhost_storage.c) will register a
+standard, NuttX block driver interface (like /dev/sda) that can
+be used to mount a file system just as with any other other
+block driver instance. In general, the binding sequence is:
+
+1. Each USB host class driver includes an initialization entry
+point that is called from the application at initialization
+time. This driver calls usbhost_registerclass() during this
+initialization in order to makes itself available in the
+event that the device that it supports is connected. Examples:
+The function usbhost_storageinit() in the file
+drivers/usbhost/usbhost_storage.c
+2. Each application must include a waiter thread thread that
+(1) calls the USB host controller driver's wait() to detect
+the connection of a device, and then (2) call the USB host
+controller driver's enumerate method to bind the registered
+USB host class driver to the USB host controller driver.
+Examples: The function nsh_waiter() in the file
+configs/nucleus2g/src/up_nsh.c and the function nsh_waiter()
+in the file configs/olimex-lpc1766stk/src/up_nsh.c.
+3. As part of its operation during the binding operation, the
+USB host class driver will register an instances of a standard
+NuttX driver under the /dev directory. To repeat the above
+example, the USB host mass storage class driver
+(drivers/usbhost/usbhost_storage.c) will register a standard,
+NuttX block driver interface (like /dev/sda) that can be
+used to mount a file system just as with any other other
+block driver instance. Examples: See the call to
+register_blockdriver() in the function usbhost_initvolume()
+in the file drivers/usbhost/usbhost_storage.c.

+The 66th release of NuttX, Version 5.19, was made on March 12, 2011
+and is available for download from the SourceForge website. This
+release includes several new features in various states of integration
+and maturity:
+
+* 486SX QEMU port. This port supports the Intel 486SX architecture
+using the QEMU simulator. Initial functionality is in place a
+partially tested. There are still some outstanding issues with
+timer interrupts.
+* Platform specific application support. A new apps/ directory
+appears in this port. This apps/ directory provides a mechanism
+for applications using NuttX to have a highly customized
+initialization process. It supports a set of end-user applications
+than can be executed (1) standalone so you can have a fully
+customized application startup, or (2) on top of NSH. Think
+of it this way: In a buckled-up embedded application, your
+end-user programs will probably have their own dedicated start-up
+logic. But, during development, you might want to have you
+applications available and executable from the NSH command line.
+This apps/ add-on (and NSH hooks) was contributed by Uros to
+accomplish just that.
+* NSH was also extended to support application specific ROMFS
+/etc/init.d/rcS start-up scripts. This feature, as well, as
+all of the above-mentioned apps/ directory support was contributed
+by Uros Platise
+* Additional NSH improvements and bug fixes. See the Changelog
+for details.
+* This release also provides a new SLIP network driver. This
+driver should support point-to-point network communications to
+a host using TCP/IP or UDP. This driver is code complete, but
+not tested in this release.
+* New RAMTRON FRAM driver (contributed by Uros Platise)
+* New generic 16550 UART driver.
+* Cortex-M3 Power improvements: Waits for Interrupt (WFI) in idle
+loop for reduced power consumption (LPC17xx and STM32 only -
+contributed by Uros Platise))
+* New waitpid() system interface.

+
+NX was develop a couple years back on hardware that supported only

+This release of NuttX extends NX so that now renders directly to
+the LCD device via its serial or parallel interface. No in-memory
+copy of the screen memory need be maintained so this solution should
+also work in MCUs with very limited SRAM.
+
+This initial release of this feature includes the verified NX

+This is the 56th release of NuttX. This release is difficult to
+categorize; NuttX-5.9 was really released because there were too
+many changes accumulating in CVS -- a few important, some unfinished
+implementations, and a couple of important bugfixes.
+
+* By far biggest change in this release is the complete implementation
+of on-demand paging support. This feature will allow you to
+execute large programs on a mass storage device (such as SPI
+FLASH) in a small RAM. All of the core on-demand paging logic
+was completed
+(see https://nuttx.apache.org/docs/latest/components/paging.html)
+and support was implemented for the ARM-9 family. A test
+configuration is in place for the NXP LPC3131. It has been
+verified that this new logic does not interfere with normal
+fixed-page ARM9 operation, but otherwise this new on-demand
+paging feature is untested.
+* Add support for the CodeSourcery toolchain to the Olimex-lpc2378
+port and for the Neuros OSD port.
+* The Neuros OSD port has been updated to work with the production
+v1.0 OSD (previously it only worked with the development board).
+* And some miscellaneous feature enhancements as detailed in the
+ChangeLog.
+
+This includes several important bugfixes:
+
+* NXP LPC17xx - Fixed a critical bug in the GPIO configuration
+logic: When attempting to set no pull-up or pull-down (floating),
+it would, instead, select pull-down.
+
+* TI/Luminary LM3Sxxxx - Fixed:
+(1) A logic error in an address table lookup.
+(2) GPIO port encoding the limited support to only 8 GPIO ports.
+
+* Corrected the lease time in the DHCPC implementation: It was
+not in host byte order.

+* And several other less important bugs as documented in the
+ChangeLog: Warnings, cornercase compilation problems, etc.

+The 67th release of NuttX, Version 6.0, was made on March 21, 2011
+and is available for download from the SourceForge website. The
+version number of this release was bumped from 5.19 to 6.0. A
+change in the major revision number is used to reflect an incompatibility
+with previous versions. In this release, the NuttX core OS
+functionality has been separated from NuttX application-related
+functionality. These are provided as separate tarballs:
+
+* nuttx-6.0.tar.gz, and
+* apps-6.0.tar.gz
+
+The purpose of this separation is both to better organize and
+modularize the NuttX source tree, but also to provide better support
+for incorporation of end-user applications with NuttX.
+
+The incompatibility results from the changes to the board configuration
+logic needed to supported the separable application. The major
+changes to the configuration include:
+
+* CONFIG_APPS_DIR - This should not be set. The default is
+../apps. This should only be set if you have a custom,
+product-specific application directory in some different location.
+
+* appconfig - Each board configuration now requires a new file
+called 'appconfig.' As its name suggests, this file provides
+new configuration information needed by the logic in ../apps.
+
+In addition to this major reorganization in the directory structure,
+this release also includes some important extensions to existing
+features and some important bugfixes. These include:
+
+* The SLIP driver was been well debugged and significantly
+re-designed. Now you can have an Ethernet connection to you
+board even if you have no Ethernet hardware. How cool is that?
+
+* The QEMU i486 port is now functional. It has also been reported
+to work on the Bifferboard (see http://bifferos.bizhat.com/).

+6.0 release introduced a detach-able application environment to
+build applications outside of the NuttX source tree. The primary
+purpose of this release is to correct numerous build problems
+introduced by that architectural change:
+
+* In many newer environments, NuttX produced strange Makefile
+errors but built correctly in older environments. A fix provided
+by Rafael Noronha was incorporated and is reported to fix those
+build problems.
+* The apps/ directory build system would not handle Windows-native
+toolchains due to obscure path formatting issues.
+* And other problems as detailed in the Changelog.
+
+Many additional changes were made in the 6.1 release for another
+major architectural change: NuttX will now build as a separately
+linked microkernel. In this build option the RTOS builds as a
+kernel, applications build separately and interface with kernel via
+system calls. Applications run in user mode and kernel logic users
+in kernel-mode. This provides a secure environment for NuttX. This
+feature is fully coded in NuttX-6.1, but has not been tested due
+to higher priority tasks that have arisen.
+
+Related to this change, support for the Cortex-M3 memory protection
+unit (MPU) has been integrated with the NuttX kernel build to provide
+an even higher level of security.
+
+NOTE: This kernel build is an option; the default build configuration
+is still the standard, flat, unsecured RTOS as in previous releases.
+
+Additional new features in this release:
+
+* Support for LPC17xx GPIO interrupts (with much support from
+Decio Renno).
+* Basic timer support for STM32 (Contributed by Uros Platise)
+* A binfs file system. This is a tiny pseudo file system that
+lets named applications to be viewed and accessed in NSH under
+the /bin directory.
+* An I2C-based driver for the LIS331DL MEMS motion sensor.
+(Contributed by Uros Platise.)
+* A configuration for the Embedded Artists LPCXpresso LPC1768 board.

+NuttX-6.15
+----------
+
+The 82nd release of NuttX, Version 6.15, was made on February 12, 2012,

+that release consists of two tarballs: nuttx-6.15.tar.gz and
+apps-6.15.tar.gz. Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+This release corresponds with SVN release number: r4387
+
+New features and extended functionality:
+
+* General Drivers: Add support for (29-bit) extended CAN IDs. Add an
+infrastructure to support battery drivers. Add a driver for MAX17040x
+battery "fuel gauge". Add support for Composite USB drivers (in
+particular for a CDC/ACM with MSC USB composite driver).
+
+Added a new RAM logging driver. This will allow debug output into
+a RAM buffer associated with a character driver at /dev/ramlog.
+Added the new command 'dmesg' to NSH that can be used to dump the
+current contents of the log. This is useful for systems that do not
+have the usual serial console (for example, if you only have a
+Telnet console with NSH).
+
+* Networking: Add a lower level, primitive socket interface. Telnet
+driver:
+
+A New Telnet daemon was created. It wraps a Telnet session within a
+character driver that can serve as a "controlling terminal." The
+Telnet session will then be inherited by tasks created from the
+Telnet session and the stdin/stdout from the created task will
+still go through the same Telnet connection.
+
+* STM32 Drivers. PWM driver pulse count was limited to 128; now is
+(essentially) unlimited. Add support for (29-bit) extended CAN IDs.
+Add support for I2C3. The SDIO driver is (mostly) verified on the
+STM32 F4 platforms.
+
+* LPC17xx Drivers. Extended the CAN driver so that the TSEG1 and TSEG2
+bit times can be set via the NuttX configuration. Add support for
+(29-bit) extended CAN IDs.
+
+* PIC32 Drivers. The PIC32 Ethernet driver is code complete (but still
+untested).
+
+* FTPD. Add a new FTP server daemon. This is based loosely on
+the hwport_ftpd library provided by Jaehyuk Cho.
+
+* Library: Add support for on_exit(). Implemented tcsetattr() and
+tcgetattr(). Moved the old, too-smart fgets() to a new application
+library function called readline(). Dumbed down the original fgets().
+Add strcasestr(), avsprintf(), inet_ntop(), and inet_pton().
+Add support to enable or disable debug output.
+
+* Build system: Support for building a 32-bit simulation executable on
+a 64-bit Linux machine. Correct a dependency issue in the arch/*/src/board
+directory.
+
+Bugfixes:
+
+* System: Correct PTHREAD_MUTEX_INITIALIZER
+
+* FAT: Fix an error in the FAT statfs() reported by David Sidrane.
+
+* STM32: Fix clock frequencies for APB2 timers. Correct AFIO register
+offset.
+
+* PIC32. Correct GPIOs used for LEDs on the Sure PIC32MX board.

+handling provided by Mike Smith. Context switching support for the
+Cortex-M4 FPU registers is now provided (in both "lazy" and "non-lazy"
+modes)
+
+* General Drivers: Added a generic "upper half" Quadrature Encoder driver.
+The USB CDC/ACM serial driver can now be dynamically connected or
+disconnected from the host (programmatically or using NSH commands).

+The PIC32MX Ethernet driver not yet fully verified (and an
+unverified SPI driver is also available).
+
+* Networking. Added a lower-level, thread-independent socket layer.
+Parts of this layer were created in 6.15 to support the FTPD
+controlling terminal; this support has been extended in order
+to support an NFS file system (not yet released).
+
+* NuttShell (NSH). NSH will now support a USB serial connection for
+the console (such as CDC/ACM). This is useful in environments
+where there is no physical serial port on the board.

+
+This release corresponds with SVN release number: r4607
+
+New features and extended functionality:
+
+* Networking: Additional low-level, thread-independent socket
+interfaces (for NFS client support).
+
+* RTC: Added a new interface call clock_synchronize(). This function
+will reload the system time from an RTC and is required when the
+system re-awakens from certain deep-sleep modes.
+
+* Graphics: Add NxConsole. This is a character device driver that
+wraps an NX window and can be re-directed for stdout. This allows,
+for example, a pop-up graphics window that contains a NuttShell (NSH)
+session. A test of NxConsole is available at apps/examples/nxconsole.
+
+* Watchdog Drivers: Added an interface definition an "upper half"
+driver to support watchdog timers.
+
+* Calypso: Support for TI Calypso-based cellphones (as supported by
+the Osmocom-BB project) was contributed by members of the Osmocom-BB
+team. This includes configurations for the Compal e88 and e99 phones.
+
+* USB Device Interface: Needed to extend the USB device interface
+because there was no mechanism for passing endpoint OUT data that
+may need to accompany a setup request.
+
+* STM32 drivers: Added some power management controls for entering
+reduced power consumption states. An OTG FS driver was completed
+and partially verified (this driver seems to be functional but since
+it has been test so lightly, it might better be listed in the
+next section "Work in progress").
+
+* PIC32 drivers: The PIC32 Ethernet driver is now stable. The PIC32
+USB device controller driver is now functional (but not yet stable).
+
+* PIC32 boards: Added support for the Sure DB-DP11212 PIC32 General
+Purpose Demo Board. There is now a PIC32 Starter Kit that
+provides NSH only through a Telnet connection.
+
+* Build System: Some header files were moved into include/nuttx.
+The goal is to move any non-standard header files to include/nuttx
+or include/arch. Moved include/math.h to include/nuttx/math.h;
+this file is now only instantiated as the 'system' math.h if
+CONFIG_ARCH_MATH_H=y is defined.
+
+* Tools: Added tools/cmpconfig.c, a tool for comparing two
+configuration files.
+
+Work in progress. This release includes some partially completed
+work that is still not ready for prime time.
+
+* NFS Client: Work is progressing on support for an NFS client
+file system. This is a port of the BSD NFS client file system
+that is being done by Jose Pablo Rojas V.
+
+* Automated Configuration: Automated configuration based on the
+kconfig-frontends tool is being incorporated into the build
+system. The configuration is still not complete enough for
+general use in this release.
+
+* STM32 Drivers: Added files that will (eventually) hold an STM32
+OTG FS host driver. This is still a work in progress.
+
+Bugfixes:
+
+* Networking: Corrected a deadlock that only occurred when
+executing the NSH 'ifconfig' command over Telnet.
+
+* File system: Fix incorrect return errno value from read() when
+the file is opened write-only.
+
+* Graphics: Fix several compilation errors that have crept into the
+multi-user NX server because of lack of use.
+
+* STM32: In order to use CAN2, both CAN1 and CAN2 clocking must be
+enabled. Fixed a troublesome bug in the STM32 F4 I2C driver that
+resulting in timeouts.
+
+* LPC17xx: Fixes for errors the crept in the LPC17xx DAC logic
+Contributed by Lzyy).

+that release consists of two tarballs: nuttx-6.19.tar.gz and
+apps-6.19.tar.gz. Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+This release corresponds with SVN release number: r4847
+
+This release features new support for a Network File System (NFS) client.
+This feature allows a tiny, embedded MCU to mount a remote file system
+exported by an NFS server and then to access the file system as it would
+any local file system. Then the tiny MCU can effectively have terabytes
+of storage!
+
+This might be useful for data collection, for MCU configuration information,
+for software updates, for providing modular, loadable code modes, controlling
+a "farm" of MCUs, ... there are many possibilities and opportunities for
+innovation!
+
+The NuttShell (NSH) now supports the following command:
+
+nfsmount <server-address> <mount-point> <remote-path>
+
+That command will mount the remote NFS server directory <remote-path> at
+<mount-point> on the target machine. <server-address> is the IP address of
+the remote server.
+
+The NFS development was the graduation project of Jose Pablo Rojas V. who
+is a student at the Instituto Tecnológico de Costa Rica (ITCR, or TEC).
+A lot of effort went into understanding what a tiny, embedded NFS client should
+do and getting the target resource usage to a bare minimum. Only around a
+kilobyte or so of memory is required to run the NFS client (and most of that
+for I/O buffers). Jose Pablo has spent several months living with NFS and
+should be congratulated.
+
+Additional new features and extended functionality:
+
+* Drivers: SSD1289 LCD driver, MIO283QT2 LCD driver
+
+* LM3S: Additional register definition header files (contributed by Max
+Neklyudov).
+
+* STM32 Boards: The STM32F4Discovery will now support an SSD1289 LCD,
+The STM3220G-EVAL board support is now equivalent to the STM3240G-EVAL
+board support.
+
+* PIC32 Boards: The Mikroelektronika PIC32MX7 MMB board port is now
+functional, very complete, and stable.
+
+* Graphics: The NxConsole will now take keyboard input from the NX graphics
+subsystem. This means that if there are multiple NxConsole windows, only
+the top instance that has focus will receive the keyboard input.
+
+* apps/: Add the capability to use an arbitrary USB device as the console
+(not necessarily /dev/console). Additional enhancements for USB consoles.
+Added the 'mv' command.
+
+Work in progress. This release includes some partially completed
+work that is still not ready for prime time.
+
+* Automated Configuration. Automated configuration based on the
+kconfig-frontends tool is being incorporated into the build
+system. The configuration is still not complete enough for
+general use in this release.
+
+* STM32 Drivers. Added files that will (eventually) hold an STM32

+* General: sleep() and usleep() return values, sig_timedwait() errno setting
+on timeout.
+* Drivers: STMPE811 touchscreen driver, USB PLC2303, USB CDC/ACM

+NuttX-6.22
+----------
+
+The 89th release of NuttX, Version 6.22, was made on September 29, 2012,
+and is available for download from the SourceForge website. Note
+that release consists of two tarballs: nuttx-6.22.tar.gz and
+apps-6.22.tar.gz. Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+This release corresponds with SVN release number: r5206
+
+Note that all SVN information has been stripped from the tarballs. If you
+need the SVN configuration, you should check out directly from SVN. Revision
+r5206 should equivalent to release 6.22 of NuttX 6.22:

+
+Additional new features and extended functionality:
+
+* RTOS: Application entry point is no longer user_start, but can be
+configured using CONFIG_INIT_ENTRYPOINT. NuttX now supports two work
+queues: A lower priority work queue (for extended processing) and a

+NuttX-6.24
+----------
+
+The 91st release of NuttX, Version 6.24, was made on December 20, 2012,
+and is available for download from the SourceForge website. Note
+that release consists of two tarballs: nuttx-6.24.tar.gz and
+apps-6.24.tar.gz. Both may be needed (see the top-level nuttx/README.txt

+
+Or (HTTP):
+
+svn checkout -r5447 http://svn.code.sf.net/p/nuttx/code/trunk nuttx-code
+
+Additional new features and extended functionality:
+
+* RTOS:
+
+- Implemented the POSIX pause() function (still has some compiance
+issues).
+- Tasking logic is extended to support the notion of address
+environments. An address environment is the key notion underlying
+"process" vs. tasks. If tasks are created with address environments
+(by binfmt), the OS will propagate that environment to child threads
+and will destroy the address environment when the "process" exists.
+- If support for the PATH variable is enabled, the OS start up logic
+will create an initial environment containing the default PATH
+setting (CONFIG_PATH_INITIAL). This initial PATH will then be
+inherited by all tasks.
+
+* Binfmt
+
+- The NuttX binary loaders have been updated to support the PATH
+environment variable. Now, if the PATH is properly defined, programs
+can be executed from mass storage using only the file name. This
+feature is added to support more standard behavior (eventually, NSH
+will support execution of programs in file systems by just entering
+the file name, perhaps in 6.25?).
+- The NXFLAT and ELF binary loaders have been extended to create
+address environments for any new tasks executed from the file system.
+This feature requires that the architecture support a memory management
+unit (MMU) and the address environment interfaces declared in
+include/nuttx/arch.h (currently, this is only supported by the z180).
+
+* Drivers: LCD driver for the Univision UG-2864AMBAG01 OLED
+
+* STM32: Support for STM32F100 high density chips contributed by Freddie
+Chopin.
+
+* STM32 Drivers: Added optional RS-485 direction bit control (from
+Freddie Chopin).
+
+* STM32 Boards:
+
+- Support for generic STM32F100RC board contributed by Freddie Chopin.
+- stm32f4discovery/nxlines: STM32F4Discovery support for the
+UG-2864AMBAG01 OLED.
+- stm32f4discovery/winbuild: A version of the NuttX OS test
+configured to build natively on Windows.
+- stm32f4discovery/elf: Now uses the PATH variable to find ELF
+executables.
+- configs/cloudctrl: Added for Darcy Gong's CloudController board
+
+* PIC32 Boards: Update the Mirtool configuration for Release 2 of the
+Mirtoo module.
+
+* Calypso: Add Calypso keypad driver. From Denis Cariki.
+
+* ZiLOG:
+
+- Add support for the z180 chip family and, specifically, for
+the P112 retro hardware (see http://p112.feedle.net/).
+- All ZiLOG configurations updated to use the current ZDS-II
+and/or SDCC toolchains.
+
+* Graphics:
+
+- Add a semaphore handshake so that operations on buffers from
+the NXMU client will be blocked until the NX server operates on the
+buffer data (from Petteri Aimonen).
+- nxtk_subwindowmove() and nxtk_getwindow(): Improvements to clipping
+logic from Petteri Aimonen.
+
+* C Library: lib/ sub-directory renamed libc/ (there is a new lib/ sub-
+directory that is used to hold all archives).
+
+* C++: Exception stubs from Petteri Aimonen.
+
+* Applications:
+
+- Add NSH hexdump command to dump the contents of a file (or character
+device) to the console (contributed by Petteri Aimonen).
+- Extend the NSH ifconfig command plus various DHCPC improvements
+(from Darcy Gong).
+
+* apps/examples:
+
+- ostest: Replace large tables with algorithmic prime number
+generation. This allows the roundrobin test to run on platforms
+with minimal SRAM (Freddie Chopin).
+- keypadtest: A new keypad test example contributed by Denis Carikli.
+- elf and nxflat: If CONFIG_BINFMT_EXEPATH is defined, these examples
+will now use a relative path to the program and expect the binfmt/
+logic to find the absolute path to the program using the PATH
+variable.
+
+* Build system:
+
+- New top-level Makefiles: Makefile.unix and Makefile.win (along with
+numerous changes to other make-related files). This adds basic
+support for building NuttX natively under Windows from a CMD.exe
+window (rather than in a POSIX-like environment). This build: (1)
+Uses all Windows style paths, (2) Uses primarily Windows batch
+commands from cmd.exe, with (3) a few extensions from GNUWin32.
+
+This capability should still be considered a work in progress
+because: (1) it has not been verfied on all targets and tools,
+and (2) still lacks some of the creature-comforts of the more
+mature environments (like a function configure.sh script and
+'make menuconfig' support).
+
+- Example Windows native builds for STM32F4Discovery, eZ80, z16f, z8,
+Z80, and Z180.
+- Several configurations have been converted to work the kconfig-
+frontends mconf configuration tool: stm32f4discovery/nxlines, and
+all eZ80, z16f, z8, Z80, and Z180 configurations.
+- Architectures now include a common Toolchain.defs file that can be
+used to manage toolchains in a more configurable way (most of this
+contributed by Mike Smith).
+
+* Build tools:
+
+- Renamed tools/winlink.sh to tools/copydir.sh.
+- Several new tools/scripts to support the Windows native build:
+tools/mkdeps.bat, tools/mkdeps.c, tools/link.bat, unlink.bat, and
+copydir.bat.
+- tools/incdir.sh and incdir.bat now support an -s option to generate
+system header file paths.
+- tools/b16.c: Fixed precision math conversion utility.
+
+Bugfixes (see the change log for details). Some of these are very important
+(marked *critical*):
+
+* RTOS: Fix some backward conditional compilation in the work queue
+logic (Freddie Chopin).
+
+* File System: Uninitialized variable caused assertions (from Lorenz
+Meier).
+
+* Drivers: Partial fix for STM32 OTGFS device drivers and fix for short,
+unaligned writes in the flash translation layer (drivers/mtd/ftl.c),
+both from Petteri Aimonen.
+
+* STM32 Drivers:
+
+- Qencoder driver and TIM3 driver fixes from Ryan Sundberg.
+- Fix timeout delay calculation in the STM32 OTG FS host driver.
+
+* LPC17xx Drivers: Resources not being properly released when I2C
+driver is un-initialized.
+
+* Graphics:
+
+- Fix logic when the mouse drags outside of the window; fix
+another "blocked message" handling case (both from Petteri Aimonen).
+- nxtk_filltrapwindow(): Correct an offset problem (also from Peterri
+Aimonen).
+- nxglib_splitline(): Correct the "fat flat line" bug.
+
+* C Library:
+
+- nrand() changes to prevent coefficients from becoming zero which
+would "lock up" the random number generate.
+- Add rounding functions to the math library (contributed by Petteri
+Aimonen).
+
+* Build system: Changes to MIN definitions in all limit.h header files
+to avoid integer overflows. For example from (-128) to (-127 - 1)
+(from Petteri Aimonen).
+
+* Applications: Modbus fixes from Freddie Chopin.
+
+As well as other, less critical bugs (see the ChangeLog for details)

+NuttX-6.25
+----------
+
+The 92nd release of NuttX, Version 6.25, was made on February 1, 2013,
+and is available for download from the SourceForge website. Note
+that release consists of two tarballs: nuttx-6.25.tar.gz and
+apps-6.25.tar.gz. Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+This release corresponds with SVN release number: r5595
+
+Note that all SVN information has been stripped from the tarballs. If you
+need the SVN configuration information, you should check out directly from
+SVN. Revision r5595 should equivalent to release 6.25 of NuttX:
+
+svn checkout -r5595 svn://svn.code.sf.net/p/nuttx/code/trunk nuttx-code
+
+Or (HTTP):
+
+svn checkout -r5595 http://svn.code.sf.net/p/nuttx/code/trunk nuttx-code
+
+Additional new features and extended functionality:
+
+* OS Initialization
+
+- Removed support for CONFIG_BUILTIN_APP_START. This is not really a
+useful feature and creates a violation of the OS layered
+architecture.
+
+* Task Creation:
+
+- Implement a simple vfork(). In NuttX-6.25, this interface is
+available only for ARM7/9, ARMv7-M (Cortext-M3/4), and MIPS32
+(PIC32MX) platforms.
+- exec() now sets the priority of the new task to the same priority as
+the parent task (instead of the arbitrary value of 50).
+- New, partially compliant implementations of execv() and execl().
+These are only partially compliant because they do not overlay any
+existing "process space" but rather create the new task and exit().
+- Add a complete implementation of posix_spawn(). This standard
+interface is a better match for an MMU-less architecture than are
+vfork() plus execv() or execl().
+- Add a task start hook that will be called before the task main
+is started. This can be used, for example, to schedule C++
+static constructors to run automatically in the context of the
+new task.
+
+* Task Parentage
+
+- Repartitioned tasking data structures. All shared resources are now
+collected together in a "task group". A task group includes the
+original task plus all of the pthreads created by the task.
+- Added support for remember the parent "task group" when a new task is
+started.
+- Added optional support to record the membership of each thread in
+the "task group".
+- Implement support for retaining child task status in the "task group"
+after the child task exists. This is behavior required by POSIX.
+But in NuttX is only enabled with CONFIG_SCHED_HAVE_PARENT and
+CONFIG_SCHED_CHILD_STATUS
+- Add internal logic to "reparent" a task. This is useful,
+for example, where the child task is created through a trampoline
+task that redirects I/O. Reparenting allows the caller of posix_spawn()
+to be reparented for the eventual child thread.
+- Added support for SIGCHLD. Sent to all members of the parent task
+group when the file member of the child task group exits.
+- If SIGCHLD and retention of child task exist status are enabled, then
+a more spec-compliant version of waitpid() is enabled.
+- New interfaces waitid() and wait() are also enabled when SIGCHLD
+is enabled.
+
+* File System
+
+- dup() and dup2() can new be used with opened files in a mounted file
+system. This supports re-direction of output in NSH to files.
+- The binfs file system was moved from apps/builtin to fs/binfs. The
+binfs file system was extended to support execution of "builtin
+applications" using exec(), execv(), execl(), or posix_spawn().
+- Added logic based on SIGCHLD to automatically unload and clean-up
+after running a task that was loaded into memory.
+
+* Binary Formats
+
+- Much of the logic for "builtin applications" was moved from
+apps/builtin to nuttx/binfmt/libbuiltin. Includes some extensions
+contributed by Mike Smith.
+- A binary loader was added for builtin applications to support
+execution of "builtin applications" using exec(), execv(),
+execl(), or posix_spawn().
+
+* Drivers:
+
+- Added logic to marshal and serialized "out-of-band" keyboard
+commands (such as cursor controls and key release events) intermixed
+with normal ASCII keypress data. The encoding is partially integrated
+in the HID keyboard driver and the decoding full integrated into the
+apps/examples hidkbd and keypadtest (the latter contributed by Denis
+Carlikli).
+- Driver for the UG-2864HSWEG01 OLED contributed by Darcy Gong.
+- Add support for removable serial devices (like USB serial). This
+support is enabled by CONFIG_SERIAL_REMOVABLE.
+
+* ARMv7-M:
+
+- Added an option to use the BASEPRI register to disable interrupts
+(instead of the PRIMASK). This eliminates some innocuous hardfaults
+that interfere with some debug tools. You need to switch to the
+BASEPRI method only if you have such tool interference.
+
+* STM32 Drivers
+
+- Bring STM32 F1 DMA capabilities up to par with the STM32 F2/F4
+(contributed by Mike Smith).
+- Add support for USART single wire mode (Contributed by the PX4
+team).
+- Updates to support for SPI DMA on the STM32 F1/F2/F4. From
+Petteri Aimonen.
+
+* STM32 Boards:
+
+- New configuration to support the UG-2864HSWEG01 OLED on the
+STM32F4Discovery board.
+- Added a posix_spawn() test configuration for the STM32F4Discovery.
+
+* LM3S/LM4F
+
+- Files and directories repartitioned to support both LM3S and LM4F
+using the STM32 organization as a model.
+- Partial definitions for the LM4F contributed by Jose Pablo Carballo
+(this is still a work in progress).
+
+* LM3S Boards
+
+- Added scripts and documentation to use OpenOCD with the LM3S (from
+Jose Pablo Carballo).
+
+* LPC176x/LPC178x
+
+- Files and directories repartitioned to support both LPC175x/LPC176x
+and the LPC177x/LPC178x families using the STM32 organization as a
+model. The LPC1788 port is a work in progress by Rommel Marcelo.
+
+* LPC176x/LPC178x Boards:
+
+- Added a configuration to support the Wave Share Open1788 board.
+This is still a work in progress by Rommel Marcelo.
+
+* LPC2148 Boards:
+
+- Add basic support for the The0.net ZP213x/4xPA board (with the LPC2148
+and the UG_2864AMBAG01 OLED).
+- Add an nxlines configuration for the ZP213x/4xPA (with the LPC2148
+and the UG_2864AMBAG01).
+
+* Simulator:
+
+- Add an nxlines configuration for the simulator.
+
+* Networking:
+
+- Add logic to work around delayed ACKs by splitting packets
+(contributed by Yan T.).
+- Split net_poll() to create the internal interface psock_poll().
+
+* LCDs:
+
+- Added support for LCD1602 alphanumeric LCD (HD4468OU controller).
+
+* Graphics:
+
+- Added 5x8 monospace font. This tiny font is useful for graph
+labels and for small bitmapped display. Contributed by Petteri
+Aimonen.
+
+* Build System:
+
+- Add an options to better manage toolchain prefixes.
+- Redesigned how the context target works in the apps/ directory.
+The old design caused lots of problems when changing configurations
+because there is no easy way to get the system to rebuild the
+context. This change should solve most the problems and eliminate
+questions like "Why don't I see my builtin application in NSH?"
+
+* Kconfig Files:
+
+- There are several new configurations that use the kconfig-frontends
+tools and several older configurations that have been converted to
+use these tools. There is still a long way to go before the conversion
+is complete:
+
+configs/sim/nxwm
+configs/sim/nsh
+configs/stm3220g-eval/nxwm
+configs/stm32f4discovery/posix_spawn
+configs/olimex-lpc1766stk/nsh
+configs/olimex-lpc1766stk/hidkbd
+configs/olimex-lpc1766stk/nettest
+configs/open1788/ostest
+configs/stm32f4discovery/nsh
+configs/stm32f4discovery/usbnsh
+configs/lm326965-ek (all configurations)
+configs/mcu123-214x/nsh
+configs/ubw32/ostest
+
+* Tools:
+
+- tools/kconfig.bat: Kludge to run kconfig-frontends from a DOS shell.
+- tools/configure.c: configure.c can be used to build a work-alike
+program as a replacement for configure.sh. This work-alike
+program would be used in environments that do not support Bash
+scripting (such as the Windows native environment).
+- tools/configure.bat: configure.bat is a small Windows batch
+file that can be used as a replacement for configure.sh in a
+Windows native environment. configure.bat is actually just a
+thin layer that executes configure.exe if it is available. If
+configure.exe is not available, then configure.bat will attempt
+to build it first.
+
+* Applications:
+
+- New and modified examples:
+
+apps/examples/wlan: Remove non-functional example.
+apps/examples/ostest: Added a test of vfork(). Extend signal
+handler test to catch death-of-child signals (SIGCHLD). Add a
+test for waitpid(), waitid(), and wait().
+apps/exampes/posix_spawn: Added a test of posix_spawn().
+
+- NSH:
+
+NSH now supports re-direction of I/O to files (but still not from).
+The block driver source argument to the mount command is now
+optional for file systems that do not require a block driver.
+NSH can now execute a program from a file system using posix_spawn().
+Added support for a login script. The init.d/rcS script will be
+executed once when NSH starts; the .nshrc script will be executed
+for each session: Once for serial, once for each USB connection,
+once for each Telnet session.
+
+- Supports a new daemon that can be used to monitor USB trace outpout.
+- Removed non-functional wlan example.
+
+Bugfixes (see the ChangeLog for details). Some of these are very important:
+
+* Tasking:
+
+- Fixed a *critical* task exit bug. Here is the failure scenario:
+(1) sched_lock() is called increments the lockcount on the current
+TCB (i.e., the one at the head of the ready to run list), (2)
+sched_mergepending is called which may change the task at the head
+of the ready-to-run list, then (3) sched_unlock() is called which
+decrements the lockcount on the wrong TCB. The failure case that
+I saw was that pre-emption got disabled in the IDLE thread, locking
+up the whole system.
+
+* Signals:
+
+- sigtimedwait() would return a bad signal number if the signal was
+already pending when the function was called.
+
+* Drivers:
+
+- Some SD cards will appear busy until switched to SPI mode for
+first time. Having a pull-up resistor on MISO may avoid this
+problem, but this fix from Petteri Aimonen makes it work also
+without pull-up.
+
+* STM32 Drivers:
+
+- STM32 FLASH driver counting error (from Freddie Chopin).
+- STM32 F4 maximum SPI frequency was wrong (corrected by Petteri
+Aimonen).
+
+* STM32 Boards
+
+- Due to cloning of untested code, the logic to control on-board
+LEDs did not work on any STM32 boards.
+- Serial devices number /dev/ttyS0-5 is there is a serial console,
+but /dev/ttyS1-6 if there is no serial console.
+
+* Binary Formats
+
+- C++ static constructors execute now using a start taskhook
+so that they execute in the context of the child task (instead
+of in the context of the parent task).
+
+* File Systems:
+
+- Several FAT-related bugs fixed by Petteri Aimonen.
+
+* Networking:
+
+- Fix poll/select issure reported by Qiang: poll_interrupt() must call
+net_lostconnection() when a loss of connection is reported. Otherwise,
+the system will not remember that the connection has been lost and will
+hang waiting on a unconnected socket later.
+- Similar issues corrected for recvfrom() and send().
+- Telnetd would hang in a loop if recv() ever returned a value <= 0.
+
+* Libraries:
+
+- fread() could hang on certain error conditions.
+- Can't handle SYSLOG output to a character device from the IDLE task
+(because the IDLE task can't block).
+
+* Build System:
+
+- Serial was driver was not being built if there is no console
+device. Obviously, the serial driver may be needed even in
+this case.
+
+* Additional Bugfixes:
+
+- sig_timedwait() and clock_time2ticks.c: Timing "rounding" logic
+- ARM9 Compilation issue with low vectors.
+- readline() return value
+- Others as detailed in the ChangeLog: HID keyboard, LPC17xx bit
+definitions, strndup(), PL2303, SYSLOG error handling, AT25,
+apps/examples.

+NuttX-6.26
+----------
+
+The 93rd release of NuttX, Version 6.26, was made on March 15, 2013,
+and is available for download from the SourceForge website. Note
+that release consists of two tarballs: nuttx-6.26.tar.gz and
+apps-6.26.tar.gz. Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+This release corresponds with SVN release number: r5745
+
+Note that all SVN information has been stripped from the tarballs. If you
+need the SVN configuration information, you should check out directly from
+SVN. Revision r5745 should equivalent to release 6.26 of NuttX:
+
+svn checkout -r5745 svn://svn.code.sf.net/p/nuttx/code/trunk nuttx-code
+
+Or (HTTP):
+
+svn checkout -r5745 http://svn.code.sf.net/p/nuttx/code/trunk nuttx-code
+
+Additional new features and extended functionality:
+
+* OS Initialization:
+
+- Add an additional call-out to support board-specific driver
+initialization during the boot-up phase (available with
+CONFIG_BOARD_INITIALIZE=y).
+
+* Tasking:
+
+- New interface task_spawn() that is like posix_spawn(), but uses
+entry point addresses like task_create().
+- Additional data restructuring as a continuation of the task group
+changes of NuttX 6.25. These data structures were moved from the
+TCB structure into the task group: pthread join data,
+atexit/on_exit callbacks, waitpid data structures, and message
+queues.
+- TCBs for tasks and pthreads are now separate structures. This
+saves a little memory since tasks do not have to carry the overhead
+for threads and vice versa.
+
+* Kernel Build:
+
+- Extensive changes were made to support the kernel build mode. In
+this mode, NuttX is built as a monolithic kernel. NuttX is built
+as a separate kernel mode "blob" and the applications are built
+as a separate user mode "blob". The kernel runs in kernel mode and
+the applications run in user mode (with the MPU restricting user
+mode accesses). Access to the kernel from the user blob is only
+via system calls (SVCalls).
+- Extensive changes were made to the syscall, SVCall, and trapping
+logic. Many internal interfaces were renamed.
+- The memory manager was extended to support both kernel- and user-
+mode allocations. Logic within the kernel needs to use the
+correct kernel- or user-space allocator, depending upon the user
+of the allocated memory.
+- The user-space blob now contains a header built in at the beginning
+of the block that provides the same information that was previously
+provided by a kludgy, auto-generated header file (user_map.h).
+- Basic support implemented for the ARMv7-M family with fragments
+also implemetned for the ARMv6-M and MIPS32 families.
+- Kernel build supported added for the LPC17xx Open1788 and for
+the Atmel SAM3U-EK board. All testing is being performed on the
+Open1788 board.
+
+* Signals:
+
+- Delivery of signals to threads within a task group is now compatible
+with the way that signals are delivered to threads within a process.
+
+* Drivers:
+
+- Add a driver for the SST29VF NOR FLASH parts.
+- USB device trace/debug feature extended to decode device-specific
+trace events to make the trace output more readable (from Petteri
+Aimonen).
+- USB MSC device driver can not support names of differing sizes
+in the USB descriptor and the SCSI fields (from Petteri Aimonen).
+- Locking added to MMC/SD SPI drivers so that MMC/SD can co-exist on
+the same bus as other SPI devices. Frequency is reset each time
+that the MMC/SD SPI has the bus locked. (from Petteri Aimonen).
+
+* ARMv6-M (Cortex-M0):
+
+- Added support for the ARM Cortex-M0 family.
+
+* nuvoTon NUC120:
+
+- Added support for the nuvoTon NUC120 MCU (Cortex-M0).
+
+* nuvoTon NUC120 Boards:
+
+- Added basic support for the nuvoTon NuTiny-SDK-NUC120 board (Cortex-M0).
+
+* LPC17xx:
+
+- Added support for the LPC177x and LPC178x families. Most of this is
+the work of Rommel Marcelo.
+
+* LPC17xx Boards:
+
+- Added support for Zilogic System's ARM development Kit, ZKIT-ARM-1769.
+From Rashid.
+- The port for the WaveShare Open1788 board is now functional. Basic
+OS test and NuttShell (NSH) configurations are functional. More
+driver development and testing is needed (from Rommel Marcelo).
+
+* LPC17xx Drivers:
+
+- Added an SD card MSI driver for the LPC178x. The driver is marginally
+functional but requires DMA capability to be reliable.
+
+* STM32
+
+- Support extended to handle the STM32 F3 family (Cortex-M4 with F1-like
+peripherals).
+
+* STM32 Boards
+
+- Added support the STMicro STM32F3Discovery board (STM32 F3).
+
+* Stellaris LM3S/LM4F
+
+- Basic support for the LM4F120 family is in place, but untested (mostly
+from Jose Pablo Carballo).
+
+* Stellaris LM4F Boards
+
+- Add support for the LM4F120 LaunchPad (untested).
+
+* Networking:
+
+- select() should now allocate a little less memory.
+
+* Memory Management:
+
+- Extended to support multiple heaps. This is used as part of
+the kernel build in order to support separator user- and
+kernel-mode heaps.
+- The stand-alone memory manager test had to be removed. It
+was too entangled and made extension of the memory manager
+nearly impossible. This is a loss.
+
+* Build System:
+
+- Several configurations converted to use the kconfig-frontends
+configuration tool. There are still many more that need to
+be converted.
+
+* C Library:
+
+- Move the workqueue logic into the C library. There is now a
+special user-space version of the work queue (which will only
+be used with a NuttX kernel build).
+- Implementation of itoa() contributed by Ryan Sundberg.
+
+* Applications:
+
+- The NSH builtin task logic now uses task_spawn() to start builtin
+applications.
+- The OS test now includes a test cased to verify task_restart().
+
+Efforts In Progress. The following are features that are partially
+implemented but present in this release. Most are expected to be fully
+available in NuttX 6.27.
+
+* LM4F120 LaunchPad port. Code is in place, but nothing has been tested.
+
+* WaveShare Open1788 port. This port as actually complete and
+functional. However, there is still ongoing development and
+testing of drivers.
+
+* Kernel Build. Much progress has been made, but there kernel build is
+not yet fully functional due to several user resources that are not yet
+properly disentangled from the kernel blob.
+
+* Conversion of old configurations to use the kconfig-frontends
+tool is an ongoing effort that will continue for some time.
+
+Bugfixes (see the ChangeLog for details). Some of these are very important:
+
+* Tasking:
+
+- The wrong PID was being signalled with SIGCHLD. It should be
+the PID of the task that create the task group, not the ID of
+the last thread to leave the task group.
+- Added logic so that some internal resources and states are recovered
+when tasks are deleted or restarted. Handle cases where there are
+outstanding timed events pending when tasks are deleted or restarted.
+
+* ARMv7-M:
+
+- Several fixes to the MPU control logic.
+
+* Drivers:
+
+- Removable serial drivers race conditions fixed.
+- MAX11802 timing bug (from Petteri Aimonen).
+
+* STM32 Drivers:
+
+- Handle cases were SPI DMA logic fails if sem_wait is awakened
+by a signal. Need to clear error flags to prevent corruption of
+subsequent transfers. Also, bit count should not be changed while
+the SPI peripheral is enabled (from Petteri Aimonen).
+- Fixes to the OTG FS device driver from Petteri Aimonen.
+- Fix typos in DMA register header file (from Yan T.)
+
+* Graphics:
+
+- Correction to the hyphen in the SANS 17x22 font (from Petteri
+Aimonen).
+
+* Networking:
+
+- Corrected errors in the socket poll/select logic. Additional
+state logic was needed to detect if the socket is still connected
+before starting the poll wait. (bug reported by Qiang Yu).
+
+* Memory Management:
+
+- mallinfo() should hold the memory manager semaphore (from Petteri
+Aimonen.
+
+* Build System:
+
+- Resolved several build errors reported by Mike Smith.
+
+* Applications:
+
+- Fixed an NSH memory leak: Needed to detach after creating each
+pthread.
+- readline() now returns EOF on any failure (instead of a negated
+errno value). This is because the underlying read is based on
+logic similar to getc. The value zero (meaning end-of-file)
+was being confused with a NUL. So if a NUL was received, the
+NSH session would terminate because it thought it was the end of
+file.

+file for build information).
+
+Additional new features and extended functionality:
+
+* OS Initialization:
+
+- Add missing registration of /dev/zero. Registration of /dev/null
+should depend upon conditional compilation. From Ken Pettit.
+
+* Tasking:
+
+- Added a new interface to set aside memory on the task's stack. This
+is used (at least in the kernel build) to hold task arguments.
+- Remove up_assert_code(). One assertion routine is enough.
+
+* Kernel Build:
+
+- Extensive changes were made to support the kernel build mode. In
+this mode, NuttX is built as a monolithic kernel. NuttX is built
+as a separate kernel mode "blob" and the applications are built
+as a separate user mode "blob". The kernel runs in kernel mode and

+mode accesses). Access to the kernel from the user blob is only
+via system calls (SVCalls).
+- Kernel build configurations for the Open1788 board and for the
+STM32F4Discovery now execute correctly.
+- Changes were made to task and thread start-up routines, signal
+handling, data structures, ARMv7-M SVCalls, stack management
+interfaces,
+
+* Drivers:
+
+- Driver for the ST7567 LCD Display Module from Univision Technology
+Inc. Contributed by Manikandan.S
+- SPI initialize functions renamed so that multiple SPI blocks can
+be initialized.
+- Extended to support the RAMTRON FM25V01 device. Contributed by
+Lorenz Meier
+- Serial drivers: TIOCSERGSTRUCT ioctls now conditioned on
+CONFIG_SERIAL_TIOCSERGSTRUCT
+
+* ARMv7-M (Cortex-M3/4):
+
+- Added support for modifiable interrupt vectors in RAM
+
+* nuvoTon NUC1xx:
+
+- Added kernel build support
+
+* Freescale Kinetis:
+
+- Add kernel build support
+- Add support for the Kinetis L family of Cortex-M0+ MCUs. Contributed
+by Alan Carvalho de Assis.
+
+* LPC17xx:
+
+- Now holds off sleep mode in the IDLE loop is DMA is in progress
+(because sleep mode will disable CPU SRAM).
+
+* LPC17xx Boards:
+
+- ZKIT-ARM-1769: Now supports the ST7567 LCD display module. Added
+an nxhello configuration for testing (Manikandan.S).
+- ZKIT-ARM-1769: Add support for both CAN1 and CAN2. Contributed by
+M.Kannan
+
+- Open1788: Basic support for the WaveShare Open1788 board is complete
+with working OS test, NSH, and graphics configurations.
+- Open1788: Integrated the LPC178x LCD driver with the WaveShare display.
+Touchscreen support is included, however, there appears to be an
+issue with the Open1788 touchscreen interrupt signal.
+- Open1788: Now supports SDRAM (used to provide the LCD framebuffer).
+- Open 1788: Reversed sense of the IDLE LCD. It is now off when the
+LPC17 is sleeping and on when awake. That is much a better visual
+indication of the dynamic CPU load
+
+* LPC17xx Drivers:
+
+- Added an LCD framebuffer driver for the LPC177x/8x family.
+- Implemented LPC17xx GPDMA support.
+- Integrated the LPC17xx GPDMA support into the SD card driver.
+- SSP driver adapted to work with the LPC178x family.
+- Separate LPC176x and LPC178x GPIO logic; this logic is too different
+to maintain in one file with conditional compilation.
+- Re-design of the GPIO logic for the LPC178x family by Rommel Marcelo.
+
+* LPC43xx:
+
+- Added kernel build support
+
+* STM32:
+
+- Added support for kernel mode build.
+- Added architecture support for the STM32 F427/F437 chips. Contributed
+by Mike Smith
+
+* STM32 Boards:
+
+- Added a configuration to support a kernel mode build of the OS test
+on the STM32F4Discovery
+
+* Stellaris LM3S/LM4F:
+
+- Added kernel build support
+- Added support for the 7 UARTs on the LM4F120
+
+* Stellaris LM4F Boards:
+
+- Added scripts and instructions to simplify use of OpenOCD with ICDI
+(JP Carballo)
+- The basic for the Stellaris LM4F120 Launchpad is complete. This
+includes support for OS test and NSH configurations. Additional
+driver development is needed.
+
+* Build System:
+
+- Directories where the same sources files are used to build different
+objects in the first and second pass kernel builds need to keep those
+objects in separate directories so that they are not constantly
+rebuilt.
+
+* Applications:
+
+- apps/system/ramtest: Add a simple memory test that can be built
+as an NSH command.
+
+* Tools:
+
+- kconfig2html is a new tool which will replace the hand-generated
+documentation of the NuttX configuration variables with auto-
+generated documentation.
+
+Efforts In Progress. The following are features that are partially
+implemented but present in this release. Most are expected to be fully
+available in NuttX 6.28.
+
+* A port to the Freescale Freedom KL25Z is complete but not yet stable
+enough. The KL25Z is a low-cost Cortex-M0+ part with 128KB of FLASH
+and 16KB of SRAM. This is is the effort of Alan Carvalho de Assis.
+
+* Conversion of old configurations to use the kconfig-frontends
+tool is an ongoing effort that will continue for some time.
+At this time, only 32% of the configurations have been converted
+to use the kconfig-frontends tools.
+
+Bugfixes (see the ChangeLog for details). Some of these are very important:
+
+* Tasking:
+
+- Fixed a critical bug: When there is pending C buffered output
+and the system is very busy, the a pthread may be blocked at
+a critical point when trying to exit. Blocking at this critical
+point would cause crashes. All entire task/thread exit logic
+paths were reviewed and failsafe mechanisms were put in place
+to assure that exitting tasks never block after task teardown
+has been started.
+
+* ARMv6-M:
+
+- Fixed parameter passing for all system call inline functions with > 3
+parameters
+- Fixed a major problem: The Cortex-M0 has no BASEPRI register but the
+logic of NuttX-6.26 was using it to manage interrupts. Switch to
+using the PRIMASK instead. This means that hardfaults will (again)
+occur when SVC instructions are executed
+
+* ARMv7-M:
+
+- Corrected Correct MPU sub-region settings for unaligned regions.
+- In exception handling with CONFIG_NUTTX_KERNEL, need to explicitly
+set and clear the privilege bit in the CONTROL
+- Fixed parameter passing for all system call inline functions with > 3
+parameters
+
+* Drivers:
+
+- Support for O_NONBLOCK was not supported in the "upper half"
+serial driver.
+- PL2303 compilation errors
+
+* Stellaris LM3S/4F:
+
+- Corrected typos in alternate function definitions.
+
+* LPC17xx Drivers:
+
+- Added a work-around for an ADC errata. From Chris Taglia
+- Only one ADC pin was configured. Need to configure all that
+are in the ADC0 set. From MKannan
+
+* File Systems:
+
+- The FAT logic was not making a distinction between directory
+non-existence and file non-existence so when it you try to
+create a file in a non-existent directory, it would create a
+file with the name of the missing directory. Reported by Andrew
+Tridgell
+- Several fixes to the FAT file system from Ronen Vainish. These
+fixes mostly involve the logic to extend directory clusters for
+the case of long file names but also include a few important
+general fixes (such as for storing 32 bit FAT values)
+- mkfatfs was writing the boot code to the wrong location. From
+Petteri Aimonen
+
+* Networking:
+
+- Fixed a compilation error when socket options are are disabled.
+Reported by Daniel O'Connor
+
+* C Library:
+
+- Corrected an error in sscanf. If %n occurs in the format statement
+after the input data stream has been fully parsed, the %n format
+specifier will not be handled. Reported by Lorenz Meier
+- strchr(str, '\0') should return a pointer to the end of the string,
+not NULL. From Petteri Aimonen
+
+* Build System:
+
+- Fix naming of NuttX target if EXEEXT is defined.
+
+* Applications:
+
+- OS test: Fix timing error in non-cancelable thread test.
+- NSH: Correct the test of the skip input parameter. Was limiting the
+range to <= count. From Ken Petit.

+NuttX-6.28
+----------
+
+The 95th release of NuttX, Version 6.28, was made on June 14, 2013,
+and is available for download from the SourceForge website. Note
+that release consists of two tarballs: nuttx-6.28.tar.gz and
+apps-6.28.tar.gz. Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+Additional new features and extended functionality:
+
+* File Systems:
+
+- SMART FLASH file system (contributed by Add Ken Pettit).
+
+* MTD (FLASH) Drivers:
+
+- Add support of MTD partitions via a new MTD driver that manages a
+set of MTD devices, each managing a subset of the FLASH region
+managed by the parent MTD driver.
+- Extended the MTD interface to provide an (optional) method to
+perform byte oriented writes if supported by the FLASH part.
+- M25Px driver re-architected to use the byte write capability (when
+possible) and to use 4KB sectors for the erase block size when the
+part supports it (from Ken Pettit).
+
+* LCD Drivers:
+
+- New interface definitions to support audio devices (from Ken Pettit)
+and alphanumeric, segment LCDs.
+
+* Wireless Drivers:
+
+- Added new driver for the wireless nRF24L01+ transceiver (from
+Laurent Latil).
+
+* Calypso:
+
+- Added support for the Pirelli DP-L10 phone (from Craig Comstock via
+Alan Alan Carvalho de Assis)
+
+* STM32:
+
+- Added an option to conditionally disable the "wfi" sleep mode. This
+is needed with certain JTAG debuggers to prevent the debug session
+from being disconnected (from Ken Pettit).
+- Added support for the STM32L (STM32L15X/STM32L16x) family.
+- Added STM32F103C4 and F103C8 chip support (from Laurent Latil).
+- Added a new interface function, stm32_dmacapable() that can be used
+to determine if DMA is possible from the specified memory address
+(from Petteri Aimonen)
+
+* STM32 Drivers:
+
+- If CONFIG_STM32_DMACAPABLE is defined, the STM32 SPI driver now uses
+stm32_dmacapable() to determine if it is possible to perform DMA
+from the specified address. This change is important for the STM32
+F4 which may have SPI data buffers allocated on the stack in CCM
+memory which cannot support the DMA (from Petteri Aimonen).
+
+* STM32 Boards:
+
+- Support added for the MikroElektronika Mikromedia for STM32F4
+development board (from Ken Pettit) with the MIO283QT2 LCD and
+touchscreen. Several graphics configurations are included.
+- The HY-mini STM32v board now uses the common SSD1289 driver
+and supported the card detect interrupt. Several new
+configurations also added and some removed (from Laurent Latil).
+- Support added for the R65105-based LCD that comes with some
+HY-Mini STM32v boards (from Christian Faure).
+- Added basic support for the STM32L-Discovery board. Drivers
+for the on-board segment LCD are included.
+- Added support for the STM32 Tiny development board based on the
+STM32 F103C8T6 MCU. This includes support for the nRF24L01+
+wireless on the board (from Laurent Latil).
+
+* Stellaris LM3S/LM4F:
+
+- Support added for a TI/Stellaris internal FLASH MTD driver (from Max
+Holtzberg).
+
+* Stellaris LM4F Boards:
+
+- The LM3S6965-EK now has configurations for the UDP discovery tool and
+for the TCP echo server (both from Max Holtzberg)
+
+* Atmel ATSAM3/4:
+
+- Reorganized, renamed, and updated directory structure to better
+support additional members of the SAM3/4 family.
+- Added support for both the ATSAM4S and ATSAM4L families. The
+ATSAM4S is similar to the ATSAM3U, but the ATSAM4L is quite a
+different beast, really much more akin to the AVR32s SoCs but
+with a Cortex-M4.
+
+* Atmel ATSAM3/4 Boards:
+
+- Added support for the Atmel SAM4L Xplained Pro development board.
+This board features the ATSAM4LC4C MCU (Cortex-M4 with 256KB FLASH +
+32KB SRAM).
+- Added support for the Atmel SAM4S Xplained development board. This
+board features the ATSAM4S16C MCU (Cortex-M4 with 1MB FLASH + 128KB
+SRAM).
+
+* PIC32MX Boards:
+
+- Added support for the 1602 segment LCD on-board the Sure PIC32MX
+board. This board will now also support a USB NuttX console and
+the USB monitor test program.
+
+* Build System:
+
+- Clean-up of almost all .gitignore files: Made scope of ignore to be
+only the current directory; Ignore .dSYM files in directories where
+.exe's may be built. Also, in Makefiles, clean .dSYM files in
+directories where an .exe may be built.
+- Standardize and consolidated all build-as-an-NSH-application
+configuration settings. Now only CONFIG_NSH_BUILTIN_APPS is
+sufficient to build an application, test, or or example as an NSH
+builtin application.
+- Added support for a generic ARM, ARMv6-M and ARMv7-M Windows EABI
+toolchains.
+
+* Libraries:
+
+- Added encoder/decoder logic to marshal and serialize special segment
+LCD (SLCD) commands intermixed with normal ASCII data. This is the
+similar to the encoding/decoding logic that is used to marshal
+special commands from a keyboard.
+- Add dprintf() and vdprintf() (the latter from Andrew Tridgell).
+- Add an application that may be built as an NSH builtin command that
+will erase FLASH using a flash_eraseall NSH command (from Ken Pettit).
+
+* Applications:
+
+- Added an MTD partition test/examples. Currently used with (1) the a
+simulation configuration to test MTD partitions on a RAM emulation
+of FLASH and (2) with the Mikroe STM32F4 configuration.
+- Added a test/example to verify alphanumeric, segment LCDs.
+- Added a simple single threaded, poll based TCP echo server based
+on W. Richard Stevens UNIX Network Programming Book (from Max
+Holtzberg).
+- Added several tests of the SMART block driver and file system (from
+Ken Pettit).
+- Added a runtime configuration for the UDP discover utility (from
+Max Holtzberg).
+- Added an example application to demo the nRF24L01 driver (from
+Laurent Latil).
+- New and modified NSH commands:
+Added a -h option to the df command to show the volume information
+in human readable form (from Ken Petit).
+Add a new mksmartfs command (from Ken Petit).
+
+Efforts In Progress. The following are features that are partially
+implemented but present in this release. Most are expected to be fully
+available in NuttX 6.28.
+
+* Audio System:
+
+- A complete audio subsystem include CODECs, higher level management,
+interface definitions, and audio drivers was contributed by Ken
+Pettit. This work has not been completely verified as of this
+release and so is categorized as a work-in-progress. At present,
+progress is blocked due to issues interfacing with the VS1053
+audio DAC on the Mikroe STM32F4 board.
+
+* kconfig-fronted Configuration:
+
+- Conversion of old configurations to use the kconfig-frontends
+tool is an ongoing effort that will continue for some time.
+At this time, only 43% of the configurations have been converted
+to use the kconfig-frontends tools.
+
+Bugfixes (see the ChangeLog for details). Some of these are very important:
+
+* Tasking:
+
+- Modify assertion in the priority inheritance logic that is reported
+to cause false alarm assertions.
+
+* Kernel Build:
+
+- Typo in syscall proxying logic corrected by Ken Pettit.
+
+* Networking:
+
+- Poll setup/teardown logic should ignore invalid (i.e., negative)
+file descriptors (from Max Holtzberg).
+- When readahead data is available, the network poll() logic should
+set POLLIN (or POLLRDNORM), not POLLOUT (from Max Holtzberg).
+
+* LCD Drivers:
+
+- Correct power controls in the MIO283QT2 LCD driver.
+
+* USB Device Controller Drivers:
+
+- Change the default IN request buffer size from 64 to 96. This will
+avoid requests of exactly MAXPACKET size and, hence, avoid so many
+NULL packets. Also, fix the OUT request buffers size to exactly the
+max packet size. It really cannot be any other size.
+
+* STM32 Drivers:
+
+- Correct some bad STM32 F1 DMA definitions that crept into the system
+a few months ago a broke STM32 F1 DMA (from Laurent Latil)
+- Fixed an error in NULL packet handling in the STM32 F1 USB device
+controller driver: If the NULL-packet needed flag ever got set,
+then it was not being cleared and infinite NULL packets resulted.
+This only affects the CDC/ACM class and was the cause of the
+failures using the USB CDC/ACM device as a NuttX console. With this
+change the USB works well as an alternative NuttX console device for
+the STM32 F1 family.
+- Correct some bad condition compilation in the RCC logic (CONFIG_
+missing from setting names). This affects some STM32 FLASH pre-
+fetch settings (from Lorenz Meier).
+- Change for hardware flow control support for STM32. The change also
+fixes incorrect operation of USART2 and UART5 in current master
+(from Lorenz Meier and Mike Smith).
+- Fixed a backward conditional in USB OTG FS host controller driver
+that prevented detection of disconnection events (from Scott).
+
+* LPC17xx Drivers:
+
+- I2C interrupt control. Also correction for a single byte read
+timeout error (from M. Kannan).
+
+* Freescale Kinetis:
+
+- Freedom KL25Z pin multiplexing and LED control corrections (from
+Alan Carvalho de Assis)
+
+* PIC32MX:
+
+- Fix NULL packet handling in the PIC32 USB device driver. Without
+this fix the CDC/ACM driver cannot be used reliably with the PIC32
+USB. With this change the USB works well as an alternative NuttX
+console device.
+
+* Graphics:
+
+- Default priorities for NxWidget and NxWM threads should be 100,
+not 50, to be consistent with other default priorities.
+
+* Applications:
+
+- Remove the CONFIG_EXAMPLES_NXTEXT_NOGETRUN option from the NXTEXT
+example. The test logic was bad for the case where this options is
+not selected. Also, completed the empty Kconfig file.
+- C++ name mangling was occurring when this example is built as an NSH
+built-in application causing the entry to be undefined when called
+from C code.
+- Add some missing NSH library configuration values (from Lorenz
+Meier).

+NuttX-6.29
+----------
+
+The 96th release of NuttX, Version 6.29, was made on July 31, 2013,
+and is available for download from the SourceForge website. Note
+that release consists of two tarballs: nuttx-6.29.tar.gz and
+apps-6.29.tar.gz. Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+Additional new features and extended functionality:
+
+* Drivers:
+
+- Generalized the SSD1306 driver and added support UG-2832HSWEG04
+which is very similar to the existing support for the
+UG-2864HSWEG01.
+- Added support for a generic bit-bang SPI driver. This includes
+both a common "upper half" driver as well as a platformp-specific
+"lower half" dirvers based on a common "template."
+
+* ARMv7-A, Cortex-A5
+
+- Added support for the ARMv7-A architecture and the Cortex-A5 in particular.
+
+* ARMv7-M, Cortex-M3/4
+
+- Modified how some registers are copied during a context switch (with
+lazy FPU register saving). This should save some context switching
+time when the context switch is due to interrupt level processing.
+
+* STM32:
+
+- Added support for a separate CCM heap. This may be useful for
+segregating allocations for CCM (which cannot be used for DMA)
+from other allocations (that may be used used for DMA).
+
+* STM32 Drivers:
+
+- DAC: Added support for DAC DMA (contributed by John Wharington).
+- I2C: An I2C driver for the STM32 F3 family (from John Wharington).
+
+* Atmel AT91 SAM/4:
+
+- Add support for SAM3X and SAM3A chips
+
+* Atmel AT91 SAM/4 Drivers:
+
+- Re-architect the SAM3/4 SPI driver so that is it compatible with the
+SPI drivers of other MCUs.
+- Added register definition file for the SAM4L LCD peripheral.
+- Added SAM4L PDCA register definition file
+
+* Atmel AT91 SAM/4 Boards:
+
+- SAM4L-Xplained: Added support for the SPI-based SD card on the I/O1
+module.
+- SAM4L-Xplained: Added a driver for the LED1 segment LCD module.
+- SAM4L-Xplained: Added support for the UG-2832HSWEG04 OLED on the
+SAM4L Xplained Pro's OLED1 module
+- SAM4S-Xplained: Added support for on-board 1MB SRAM
+- Arduino Due: Basic support for the Arduino Due (SAM3X) is now
+included.
+- SAM3U-EK: The touchscreen is now functional.
+
+* Atmel AT91 SAMA5D3
+
+- Added support for the Atmel AT91SAMA5D3 Cortex-A5 chip family.
+
+* Atmel AT91 SAMA5D3 Boards
+
+- Added support for the Atmel SAMA5D3x-EK boards which use the AT9
+SAMA5D3x chips (x=1,3,4,5).
+
+* Freescale KL25Z Drivers
+
+- Freescale KL25Z TSI register definitions and example TSI driver for
+the Freedom KL25Z board from Alan Carvalho de Assis.
+- Added SPI driver and register definitions for the Freescale KL25Z.
+- Added a framework for controlling SPI-related discrete inputs and
+outputs. Taken from work by Alan Carvalho de Assis
+
+* Build System:
+
+- New sub-directories to hold SPI-related files: includes/nuttx/spi.h
+moved to include/nuttx/spi/.; SPI-related Kconfig info moved from
+drivers/Kconfig to drivers/spi/kconfig.
+- Finally... I changed the naming of configuration variables like
+CONFIG_DRAM_ to CONFIG_RAM_. This has bothered me for a long time
+since most boards don't have DRAM. The more generic RAM naming
+should not produce so much cognitive dissonance
+
+* Libraries:
+
+- Added CRC16 support.
+
+* Applications:
+
+- Added Zmodem file transfer support. This may be used as an embedded
+library or may be built as 'sz' and 'rz' commands that can be
+executed from NSH.
+- C++ initializers should be set once and, preferably, in the context
+of the task that uses any C++ statically initialized classes. This
+only becomes an issue if cxxtest or helloxx are built as NSH builtin
+applications. Then you want the initialization done in cxxtext or
+helloxx and not in NSH (and certainly not twice). Added
+configuration options to control who does the C++ initialization.
+NSH now does not do C++ initialization be default and must be
+configured to do otherwise. Conversely, cxxtest and helloxx
+will always do C++ initialization unless configured do otherwise.
+- examples/cxxtext: Add ostream test as provided by Michael.
+- NSH: Added a 'cmp' command that can be used to compare two files
+for equivalence. Returns an indication if the files differ.
+Contributed by Andrew Tridgell (via Lorenz Meier).
+
+Efforts In Progress. The following are features that are partially
+implemented but present in this release. They are not likely to be
+completed soon.
+
+* Audio System:
+
+- A complete audio subsystem include CODECs, higher level management,
+interface definitions, and audio drivers was contributed by Ken
+Pettit. This work has not been completely verified as of this
+release and so is categorized as a work-in-progress. At present,
+progress is blocked due to issues interfacing with the VS1053
+audio DAC on the Mikroe STM32F4 board.
+
+* kconfig-fronted Configuration:
+
+- Conversion of old configurations to use the kconfig-frontends
+tool is an ongoing effort that will continue for some time.
+At this time, only 45% of the configurations have been converted
+to use the kconfig-frontends tools.
+
+Bugfixes (see the ChangeLog for details). Some of these are very important:
+
+* File Systems:
+
+- Fixed compilation error if no file systems are enabled: Change
+error to ERROR.
+- Read-Ahead/Write buffering: Correct typos that can cause failures
+in some configurations (From Chia Cheng Tsao).
+
+* Drivers
+
+- Remove the wait for the touchscreen busy bit in the ADS7843E driver.
+From my reading of the ADS7843 spec, it would not be appropriate to
+wait for the BUSY bit to de-asserted anyway (since it is only de-
+asserted when we read the data). Most boards do not even bother to
+provide the BUSY bit.
+- MMC/SD SPI based driver: Driver needs to make sure that the SPI
+mode and data width are correct.
+- ENC28J60: Change buffer ordering to work around Errata. From Dave
+(ziggurat29).
+
+* USB Device Controller Drivers:
+
+- Fixed a typo in the composite device driver unitialization logic.
+DEV1 should be DEV2 in one case.
+- usbdev.h: Fix some typos that cause compiler errors when
+CONFIG_USBDEV_DMA and CONFIG_USBDEV_DMAMEMORY are selected (From
+Chia Cheng Tsao).
+
+* ARM9:
+
+- Fix a bug (uninitialized register error) that crept in the ARM9
+boot-up code several years ago. Obviously no one has used the
+ARM9 NuttX port for years!
+
+* STM32 Drivers:
+
+- Fix STM32 OTF FS endpoint allocation logic. Apparently the same
+endpoint can be allocated as both an IN or an OUT endpoint. The
+existing implementation only supported one allocation, either IN or
+OUT. This resulted in failures to allocate endpoints when used with
+the CDC/ACM + MSC composite driver (From Chia Cheng Tsao).
+- SDIO: Add support for the data block end (DBCKEND) interrupt to
+terminate transfers (From Chia Cheng Tsao).
+- DAC: Fixed numerous DAC driver errors and added support for DAC
+DMA (contributed by John Wharington).
+
+* SAM3/4:
+
+- SAM4S: Correct configuration of PIO pins for SAM4S B and C peripherals.
+- Need to disable write protection before configuring PIO pins.
+- GPIO configuration logic must protect against re-entrancy.
+- Clocking must be applied to the SMC module for the 3X and 3A family in
+order for the NFC SRAM to be functional.
+- Fixed some errors for interrupts on ports D-F.
+
+* SAM3/4 Drivers:
+
+- Common SPI driver: Fix SPI mode setting. In the SAM3/4 family, the
+clock phase control (CPHA) is inverted (NPHA). Also fixed an
+incorrect pointer test. Was checking if the wrong pointer was NULL.
+
+* SAM3/4 Boards:
+
+- SAM3U-EK: Fix polarity of the /PENIRQ signal (it is active low).
+The SAM3U-EK board now runs at 96MHz.
+
+* Applications:
+
+- apps/examples/nxhello: Minor fix for compilation error when the
+display resolution is low (< 8bpp) due to a typo that has been there
+for a long time. Also Correct default colors when in Y1 code mode.
+- apps/system/ramtest: The RAM test was not correctly built
+into the configuration and build system.
+- apps/examples/composite: Change to prevent some false alarm debug
+assertions (From Chia Cheng Tao).
