- * include/semaphore.h, sched/sem_holders.c, and lib/semaphore/sem_init.c:
- Fix some strange (and probably wrong) list handling when
- CONFIG_PRIORITY_INHERITANCE and CONFIG_SEM_PREALLOCHOLDERS are defined.
- This list handling was probably causing errors reported by Mike Smith
- * sched/sched_waitpid.c: Fix a possible issue with logic logic that
- should be brought into a critical section (suggested by Mike Smith)
- * sched/sched_setuptaskfiles.c: Should be 'struct socket' not
- 'struct sockets'. How did this compile before? (found by Kate)
- * syscall/syscall.csv: Fix prototype for usleep() and prctl() (also
- from Kate).
- * arch/arm/src/lpc17xx/lpc17_ethernet.c: Conditionally elide setting PHY
- speed/duplex. This does not work for certain PHYs. Still some unresolved
- issues (also from Kate).
- * tools/Config.mk, Makefile, configs/*/Make.defs: Add a new Makefile
- fragment to de-quote certain strings from the Kconfig logic that
- need to be used at path segments (Richard Cochran).
- * arch/arm/src/stm32/stm32_usbotghost.c: The STM32 USB host driver only
- works with debug turned on. The problem appears to be that with debug
- OFF, there are more NAKs occuring in more places than before and this
- reveals a variety of errors. This check in improves NAK robustness
- for control transfers but does not resolve all of the issues.
- * configs/stm3220g-eval/*/defconfig: Calibrated delay loop. It had
- never been calibrated was way off.
- * sched/sem_holder.c: Add logic to handler some priority inheritance
- cases when sem_post() is called from an interrupt handler. The
- logic is clearly wrong, but it is not known if this is the
- cause of any known bugs.
- * lib/stdio/lib_perror(): Add perror(). Contributed by Kate.
- * lib/string/lib_strerror(): Add option CONFIG_LIBC_STRERROR that
- is now required to enabled strerror(). Add an option
- CONFIG_LIBC_STRERROR_SHORT that can be used to output shortened
- strings by strerror().
- * arch/arm/src/stm32/stm32_usbotghost.c: Finally... the USB OTG FS
- appears to handle NAKing correctly.
- * configs/stm32f4discovery/*: Added and verifed support for USB OTG FS
- host on the STM32F4Discovery board.
- * configs/*/defconfig: Remove configuration documentation from config
- files. It is redundant, error-prone, and difficult to maintain.
- Configuration documentation is available in configs/README.txt for
- common configurations and in configs/*/README.txt for board and MCU-
- specific configurations.
- * configs/stm3240g-eval: Add USB host support.
- * sched/os_bring.c, configs/*/defconfig, tools/mkconfig.c, and others: Added
- configuration variable CONFIG_USER_ENTRYPOINT that may be used to change
- the default entry from user_start to some other symbol. Contributed by
- Kate. NOTE: This change does introduce a minor backward incompatibility.
- For example, if your application uses NSH as its start-up program, then your
- build will now fail because it will be unable to find "user_start". The fix
- for this link failure is to add the following to your configuration file:
- CONFIG_USER_ENTRYPOINT="nsh_main".
- * libs/stdio/lib_libfread.c and lib_*flush*.c: Correct a couple of
- error cases where the lib semaphore was not be released on error
- exits (thanks Ronen Vainish). Also, improved some error reporting:
- the generic ERROR was being used instead of the specific errno
- value; the errno variable was not always set correctly.
- * tools/mkfsdata.pl: The uIP web server CGI image making perl script was
- moved from apps/netutils/webserver/makefsdata to nuttx/tools/mkfsdata.pl
- (Part of a larger change submitted by Max Holtzberg).
- * configs/stm3240g-eval/script/ld.script: All of the identical ld.script
- files for the STM3240G-EVAL were replaced by one version in this directory.
- * configs/stm3240g-eval/webserver: Configuration submitted by Max Holtzberg
- for testing the changes to the uIP web server (see apps/ChangeLog.txt).
- * lib/stdio/lib_perror.c: Remove CONFIG_LIBC_PERROR_DEVNAME. What was I
- thinking? Arbitrary streams cannot be shared by different tasks.
- * tools/mksyscall.c, csvparser.c, and csvparser.h: Separate CSV parsing
- logic from mksyscall.c into files where it can be shared.
- * tools/mksymtab.c: Add a tool that can be used to convert a CSV file
- into a NuttX-style symbol table.
- * sched/work_cancel.c: Fix a bad assertion (reported by Mike Smith)
- * configs/stm3210e-eval/src/up_idle.c: Correct some power management
- compilation errors (reported by Diego Sanchez).
- * include/nuttx/wqueue.h, sched/work*, and others: Added logic to support
- a second, lower priority work queue (CONFIG_SCHED_LPWORK).
- * arch/arm/src/stm32/stm32_dma.c, chip/stm32*_memorymap.h: FSMC SRAM is
- only 16-bits wide and the SDIO DMA must be set up differently.
- * arch/arm/src/stm32/stm32_dma.c: Back out the 16-bit DMA change. It
- is incorrect.
- * configs/: Make use of UART4/5 vs USART4/5 consistent in all places.
- * Kconfig: Serial 2STOP setting must be integer 0/1, not a boolean.
- * lib/misc/sendfile.c and include/sys/sendfile.h: Add a Linux style
- sendfile() (non-standard!)
- * Kconfig: Refactor serial settings (moved from chip to drivers/serial).
- AVR "teensy" now builds with Kconfig (contributed by Richard Cochran).
- * Kconfig: Add configuration settings for the LPC17xx
- * Kconfig: Add configuration settings for the LM3S (from Richard Cochran).
- * Kconfig: Verify configuration settings for the STM32. This includes
- changes in the way that the external SRAM is configured: Define
- CONFIG_HEAP2_SIZE (decimal) instead of CONFIG_HEAP2_END (hex).
- * tools/configure.sh: Don't append the apps directory path setting
- if the correct setting is already in defined in the defconfig file.
- * fs/fat/fs_utils.c: Improperly constructed bool expression. This
- would cause many unnecessary writes to FLASH (Thanks Ronen Vainish).
- * Kconfig: Verify configuration settings for the LPC43xx. This includes
- some corrections to configuration variable names and defconfig settings.
- * Kconfig: Add and verify configuration settings for the LPC31xx.
- * arch/arm/src/stm32/stm32_uart.h and stm32_serial.c: Add logic to
- re-initialize the console UART as needed to enable DMA on the
- console UART (contributed by Mike Smith).
- * net/recvfrom.c, net/Kconfig, include/nuttx/net/uipopt.h: Remove delay
- after receiving data. That has historical reasons to be there (it
- was needed before read-ahead buffering was added), but kills performance.
- (Noted by Max Holtzberg).
- * configs/shenzhou: Add beginnings of a board configuration for the
- Shenzhou STM32107 board (see www.armjishu.com). Very little is in
- place as of this initial check-in.
- * QEMU: Fixes from Richard Cochran to build QEMU with Kconfig files.
- * arch/*/src/Makefile: Remove some old logic that was kicked off
- when CONFIG_BOOT_RUNFROMFLASH=y. The old logic used to use
- objcopy to move sections. Newer logic changes the load position
- of sections in the the linker script. As far as I can tell, there
- is nothing in the source tree now that depends on the old way of
- doing things (if I am wrong, they will need a change to the linker
- script).
- * configs/fire-stm32v2: Configuration for the M3 Wildfire board. I
- don't know very much about this board other than is has an
- STM32F103VET6 chip, LCD, touchscreen, and ENC28J60 network. Very
- little is in place on the initial check-in.
- * configs/shenzhou: Coding for the Shenzhou board port is complete,
- but tested has been deferred until I get the right tools.
- * arch/arc/include/stm32/chip.h and arch/arm/src/stm32/chip.h:
- Add support for the STM32F103VET6.
- * fs/fs_fdopen.c: Bad check for failure to allocate memory. (Noted
- by Ronen Vainish).
- * drivers/mmcsd/mmcsd_sdio.c: If the MMC/SD driver were ever
- uninitialized then there would be a double release of memory
- (Noted by Ronen Vainish).
- * fs/mmap/fs_rammap.c: Fix logic error and errno check (contributed
- by Kate).
- * arch/avr/src: Fixes from AVR32 build errors that have crept in
- over the time; incorporated Kconfig for AVR3 (Richard Cochran).
- * fs/fat and include/nuttx/fs/fat.h: The FAT file system allocates
- memory for sector I/O buffers used to exchange data with the
- configured block driver. In some contexts, the block driver may
- require DMA-capable memory. If CONFIG_FAT_DMAMEMORY is defined,
- then the FAT FS will use platform-provided DMA memory allocators
- to allocate the block driver I/O buffers.
- * CONFIG_NET_ENC28J60 renamed CONFIG_ENC28J60 to be consistent
- in all places.
- * drivers/enc28j60.c, include/nuttx/net/enc28j60.h, and
- olimex-strp711/src/up_enc28j60.c: No longer passes IRQ number
- as a parameter. Instead now passes a call table to manage
- ENC28J60 GPIO interrupts. That is because GPIO interrupts are
- handled in different ways by different MCUs and some do not
- support IRQ numbers for GPIO interrupts.
- * mm/mm_gran* and include/nuttx/gran.h: Add a simple granule-
- based allocator. The intent of this allocator is to support
- simple allocation of DMA I/O buffers. The initial check-in
- is code complete but untested (not event built into the
- mm/Makefile yet.
- * confgs/fire-stm32v2: The board port is basically functional.
- Not all features have been verified. The ENC28J60 network
- is not yet functional.
- * configs/stm3240g-eval/discover: A configuration for testing
- the UDP discovery utility. Contributed by Max Holtzberg.
- * mm/README.txt: Add a new README file.
- * include/nuttx/usb/usb.h, arch/*/src/*usb.c, and arch/*/src/*otg*.c:
- Add hooks to to use common, external DMA buffer allocation
- implementation.
- * net/recvfrom.c: Don't block in recvfrom if (1) read-ahead buffering
- is enabled and (2) some data was obtained from read-ahead buffers.
- Blocking is a bad idea in that case because there is no timeout!
- (submitted by Max Holtzberg).
- * configs/stm3240g-eval/xmlrpc: An example configuration for the
- Embeddable Lightweight XML-RPC Server at apps/examples/xmlrpc.
- See http://www.drdobbs.com/web-development/\
- an-embeddable-lightweight-xml-rpc-server/184405364 for more info.
- Contributed by Max Holtzberg.
- * configs/*/nxwm/defconfig and sched/task_exithook.c: Fixes for
- bugs that crept in during recent changes. (Submitted by Max
- Holtzberg).
- * arch/arm/include/armv7-m/irq.h: Fix a critical bug in irqsave().
- It looks like sometimes the compile will re-order some instructions
- inapproapriately. This end result is that interrupts will get
- stuck off.
- * drivers/mtd/w25.c: Beginning of a driver for the Windbond SPI
- FLASH family (W25x16, W25x32, and W25x64). The initial check-in
- is basically just the SST25 driver with some name changes.
- * arch/arm/include/armv7-m/irq.h and arch/arm/src/stm32/stm32_spi.c:
- Back out the last change in irq.h. It is (most likely) fine the
- way it was. The really interrupt related problem was in stm32_spi.c:
- When SPI3 is not enabled, then the irqrestore() falls in the
- else clause.
- * include/nuttx/compiler.h and other files: Moved always_inline
- and noinline __attributes__ here. Also replaced all occurrences
- of explicit __atributes__ in other files with definitions from
- this header file.
- * drivers/mtd/w25.c: The Windbond SPI FLASH W25 FLASH driver is
- code complete (but still untested).
- * arch/arm/src/stm32/stm32_i2c.c: I2C improvements from Mike Smith.
- Unified configuration logic; dynamic timeout calculations;
- I2C reset logic to recover from locked devices on the bus.
- * configs/*/*/Make.defs, tools/Config.mk, Makefile: Refactor all
- common make definitions from the various Make.defs files into
- the common tools/Config.mk. Add support for a verbosity options:
- Specify V=1 on the make command line in order to see the exact
- commands used in the build (Contributed by Richard Cochran).
- * drivers/net/enc28j60.c: The ENC28J60 Ethernet driver is
- now functional.
- * configs/fire-stm32v2: Add support or the fire-stm32v3 board as
- well (untested because I do not have a v3 board).
- * lib/stdio/lib_sscanf.c: Add %n psuedo-format (from Kate).
- * lib/stdio/lib_sscanf.c: There is an issue of handling input
- when (1) no fieldwidth is provided and (2) there is no space
- seperating the input values. No solutions is in place for this
- case now (either space or a fieldwidth must be provided). But
- at least some of the bad logic that attempted to handle this
- case has been removed (noted by Kate).
- * arch/arm/src/stm32/stm32_eth.c: DMA buffer sizes must be an
- even multiple of 4, 8, or 16 bytes.
- * arch/arm/src/stm32/stm32_idle.c: Fixes STM32F107 DMA issues:
- We cannot go into sleep mode while Ethernet is actively DMAing.
- * configs/shenzhou/src/up_ssd1289.c: Add infrastructure to support
- SSD1289 LCD. Initial checkin is just a clone of the
- STM32F4Discovery's FSMC-based LCD interface. The Shenzhou
- will need a completely need bit-banging interface; this
- initial check-in is only for the framework.
- * configs/shenzhou/src/up_ssd1289.c: Bit-banging driver is
- code complete.
- * configs/shenzhou/src/up_lcd.c: Oops. Shenzhou LCD does not
- have an SSD1289 controller. Its an ILI93xx. Ported the
- STM3240G-EVAL ILI93xx driver to work on the Shenzhou board.
- * configs/shenzhou/nxwm: Added an NxWM configuration for the
- Shenzhou board. This is untested on initial check-in. It will
- be used to verify the Shenzhou LCD driver (and eventually the
- touchscreen driver).
- * configs/shenzhou/src/up_touchscreen.c: Add ADS7843E touchscreen
- support for the Shenzhou board. The initial check-in is untested
- and basically a clone of the the touchscreen support for the SAM-3U.
- * tools/cfgparser.c: There are some NxWidget configuration
- settings that must be de-quoted.
- * arch/arm/src/stm32/Kconfig: There is no SPI4. Some platforms
- support SPI3 and some do not (still not clear).
- * nuttx/configs/shenzhou: Various fixes to build new NxWM
- configuration.
- * configs/shenzhou: Oops. The Shenzhou LCD is and SSD1289,
- not an ILI93xx.
- * configs/shenzhou/src/up_ssd1289.c: The LCD is basically functional
- on the Shenzhou board.
- * graphics/nxmu: Correct some bad parameter checking that caused
- failures when DEBUG was enabled.
- * arch/arm/src/armv7-m/nvic.h: Add bit definitions for the AIRCR
- register.
- * drivers/input/ads7843.c: Need semaphore protection in logic
- that samples the position.
- * drivers/lcd/ssd1289.c: On some platforms we are unable to
- read the device ID -- reason unknown; workaround in place.
- * drivers/input/ads7843.c: Add thresholding options and an
- option to swap X and Y positions. Fix some logic errors in
- the SPI locking/selecting logic.
- * arch/arm/src/armv7-m/up_systemreset.c: Add logic to reset
- the Cortex-Mx using the AIRCR register. Contributed by Darcy
- Gong.
- * arch/arm/src/stm32/up_eth.c: Add logic specifically for the
- DM9161 PHY. If the DM9161 failed to initialize, then use the
- up_sysemreset() logic to reset the MCU. Contributed by Darcy
- Gong.
- * arch/arm/src/stm32/stm32_gpio.c: Add missing logic to set bit
- for SPI3 remap. This fixes the XPT2046 touchscreen driver using
- drivers/input/ads7843.c
- * configs/shenzhou/src/up_ssd1289.c: Fix naming error in
- conditional compilation.
- * configs/shenzhou/nxwm/defconfig: Disable reading from the LCD.
- This does not work. The hardware and the driver support the
- capability, but there is some bug that causes memory corruption.
- The work around for now: Just disable reading from the LCD.
- * drivers/lcd/ssd1289.c: Add some logic to reduce the amount of
- output when CONFIG_DEBUG_LCD is enabled.
- * configs/shenzhou/nxwm/defconfig: Bug found and fixed... The
- original configuration had too much stuff turned on. Reducing
- stack sizes, some features, and buffer sizes made the
- configuration reliable (Reading from the LCD is still disabled).
- * net/uip/uip_icmpping.c: Fix problem that prevented ping from
- going outside of local network. Submitted by Darcy Gong
+ * arch/arm/src/stm32/stm32_rng.c, chip/stm32_rng.h, and other files:
+ Implementation of /dev/random using the STM32 Random Number
+ Generator (RNG).
+ * board.h file for shenzhou, fire-stm32v2, and olimex-stm32-p107:

+ by the STM32 watchdog driver.
+ * CONFIG_EXAMPLES_*: To make things consistent, changed all occurrences
+ of CONFIG_EXAMPLE_* to CONFIG_EXAMPLES_*.
+ * drivers/mtd/w25.c and configs/*/src/up_w25.c: Several fixes for the
+ W25 SPI FLASH.
+ * configs/*/Make.defs: All buildroot tools now use the extension

+ * configs/shenzhou/*/Make.defs: Now uses the new buildroot 4.6.3
+ EABI toolchain.
+ * lib/stdio/lib_libdtoa.c: Another dtoa() fix from Mike Smith.
+ * configs/shenzhou/src/up_adc.c: Add ADC support for the Shenzhou
+ board (Darcy Gong).
+ * configs/shenzhou/thttpd: Add a THTTPD configuration for the
+ Shenzhou board (Darcy Gong).
+ * include/termios.h and lib/termios/libcf*speed.c: The non-standard,
+ "hidden" c_speed cannot be type const or else static instantiations
+ of termios will be required to initialize it (Mike Smith).
+ * drivers/input/max11802.c/h, and include/nuttx/input max11802.h: Adds
+ support for the Maxim MAX11802 touchscreen controller (contributed by
+ Petteri Aimonen).
+ * graphics/nxtk/nxtk_events.c: Missing implementatin of the blocked
+ method. This is a critical bugfix for graphics support (contributed
+ by Petteri Aimonen).
+ * drivers/usbdev/pl2303.c, drivers/usbdev/usbmsc.h, and
+ include/nuttx/usb/cdcacm.h: USB_CONFIG_ATTR_SELFPOWER vs.
+ USB_CONFIG_ATT_SELFPOWER (contributed by Petteri Aimonen).
+ * arch/arm/src/armv7-m/up_memcpy.S: An optimized memcpy() function for
+ the ARMv7-M family contributed by Mike Smith.
+ * lib/strings/lib_vikmemcpy.c: As an option, the larger but faster
+ implemementation of memcpy from Daniel Vik is now available (this is
+ from http://www.danielvik.com/2010/02/fast-memcpy-in-c.html).
+ * lib/strings/lib_memset.c: CONFIG_MEMSET_OPTSPEED will select a
+ version of memset() optimized for speed. By default, memset() is
+ optimized for size.
+ * lib/strings/lib_memset.c: CONFIG_MEMSET_64BIT will perform 64-bit
+ aligned memset() operations.
+ * arch/arm/src/stm32/stm32_adc.c: Need to put the ADC back into the
+ initial reset in the open/setup logic. Opening the ADC driver works
+ the first time, but not the second because the device is left in a
+ powered down state on the last close.
+ * configs/olimex-lpc1766stck/scripts: Replace all of the identical
+ ld.script files with the common one in this directory.
+ * configs/stm3220g-eval/scripts: Replace all of the identical
+ ld.script files with the common one in this directory.

+ ld.script files with the common one in this directory.
+ * binfmt/elf.c, binfmt/libelf, include/elf.h, include/nuttx/elf.h: Add
+ basic framework for loadable ELF module support. The initial check-
+ in is non-functional and is simply the framework for ELF support.
+ * include/nuttx/binfmt.h, nxflat.h, elf.h, and symtab.h: Moved to
+ include/nuttx/binfmt/.
+ * arch/sim/src/up_elf.c and arch/x86/src/common/up_elf.c: Add
+ for ELF modules.
+ * arch/arm/include/elf.h: Added ARM ELF header file.
+ * include/elf32.h: Renamed elf.h to elf32.h.
+ * configs/stm32f4discovery/ostest: Converted to use the new
+ Kconfig-based configuration system.
+ * configs/stm32f4discovery/elf and configs/stm32f4discovery/scripts/gnu-elf.ld
+ Add a configuration for testing the ARM ELF loader.
+ * binfmt/libelf: Can't use fstat(). NuttX does not yet support it. Damn!
+ * binfmt/libelf: The basic ELF module execution appears fully functional.
+ * configs/shenzhou/src/up_relays.c: Add support for relays from the
+ Shenzhou board. Contributed by Darcy Gong.
+ * lib/fixedmath: Moved the old lib/math to lib/fixedmath to make room for
+ the math library from the Rhombus OS
+ * lib/math: Now contains the math library from the Rhombus OS by Nick Johnson
+ (submitted by Darcy Gong).
+ * include/float.h: Add a first cut at the float.h header file. This
+ really should be an architecture/toolchain-specific header file. It
+ is only used if CONFIG_ARCH_FLOAT_H is defined.
+ * lib/math: Files now conform to coding standards. Separated float,
+ double, and long double versions of code into separate files so that
+ they don't draw in so much un-necessary code when doing a dumb link.
+ * binfmt/libelf: The ELF loader is working correctly with C++ static
+ constructors and destructors and all.
+ * Documentation/NuttXBinfmt.html: Add documentionof the binary loader.
+ * configs/sim/ostest: Converted to use the mconfig configuration tool.
+ * configs/sim/cxxtest: New test that will be used to verify the uClibc++
+ port (eventually).
+ * include/nuttx/fs/fs.h, lib/stdio/lib_libfread.c, lib_ferror.c,
+ lib_feof.c, and lib_clearerr.c: Add support for ferror(), feof(),
+ and clearerror(). ferror() support is bogus at the moment (it
+ is equivalent to !feof()); the others should be good.
+ * configs/stm32f4discovery/include/board.h: Correct timer 2-7
+ base frequency (provided by Freddie Chopin).
+ * include/nuttx/sched.h, sched/atexit.c, and sched/task_deletehook.c:
+ If both atexit() and on_exit() are enabled, then implement atexit()
+ as just a special caseof on_exit(). This assumes that the ABI can
+ handle receipt of more call parameters than the receiving function
+ expects. That is usually the case if parameters are passed in
+ registers.
+ * libxx/libxx_cxa_atexit(): Implements __cxa_atexit()
+ * configs/stm32f4discovery/cxxtest: New test that will be used to
+ verify the uClibc++ port (eventually). The sim platform turned not
+ to be a good platform for testing uClibc++. The sim example will not
+ run because the simulator will attempt to execute the static
+ constructors before main() starts. BUT... NuttX is not initialized
+ and this results in a crash. On the STM324Discovery, I will have
+ better control over when the static constructors run.
+ * RGMP 4.0 updated from Qiany Yu.
+ * configs/*/Make.defs and configs/*/ld.script: Massive clean-up
+ and standardization of linker scripts from Freddie Chopin.
+ * net/netdev_ioctl.c: Add interface state flags and ioctl calls
+ to bring network interfaces up and down (from Darcy Gong).
+ * config/stm32f4discovery: Enable C++ exceptions. Now the entire
+ apps/examples/cxxtest works -- meaning the the uClibc++ is
+ complete and verified for the STM32 platform.

- Kate.
- * apps/netutils/webserver/httpd.c: Add support for Keep-alive connections
- (from Kate).
- * apps/NxWidget/Kconfig: This is a kludge. I created this NxWidgets
- directory that ONLY contains Kconfig. NxWidgets does not live in
- either the nuttx/ or the apps/ source trees. This kludge makes it

+ files.
+ * CONFIG_EXAMPLES_*: To make things consistent, changed all occurrences
+ of CONFIG_EXAMPLE_* to CONFIG_EXAMPLES_*.

+ networks where the ICMP ECHO round trip time may exceed the ping interval.
+ * apps/examples/nxtext/nxtext_main.c: Fix bad conditional compilation
+ when CONFIG_NX_KBD is not defined. Submitted by Petteri Aimonen.

- * Add patch submitted by Dimiter Georgiev to work around problems in building
- GDB 6.8 with versions of Cygwin > 1.7.
- * configs/i486-defconfig-4.3.3 - Builds an i486 cross development toolchain
- using gcc 4.3.3. Why wouldyou want such a thing? On Linux, of course,
- such a thing is not needed because you can use the installed GCC to build
- i486 ELF binaries. But that will not work under Cygwin! The Cygwin
- toolchain (and probably MinGW), build DOS MZ format executables (i.e.,
- .exe files). That is probably not usable for most NuttX targets.
- Instead, you should use this i486-nuttx-elf-gcc to generate true ELF binaries
- under Cygwin.
- * Makefile - Alter copy arguments to avoid permissions problems when
- copying NuttX header files.
- * toolchain/nxflat/nxflat.mk and Makefile - Fix include paths.
