The change log associated with the release is available here. Unreleased changes after this release are available in SVN. These unreleased changes are also listed here.
- The release of NuttX-6.3 follows only a nines days after the release of version 6.2. - This special back-to-back release was made so that the current released version of - NuttX will correspond to the initial release from the RGMP project. -
-- This release adds architecture support and build configuration for RGMP. - RGMP is a project for running GPOS and RTOS simultaneously on multi-processor platforms. - See the RGMP Wiki for further information about RGMP. -
-- This release also includes support for STM32 FLASH, build improvements, and initial, incomplete support for the MicroChip PIC32MX MCU. - Bug fixes are included for some build problems, USB host class driver error handling, NX graphics color mapping, and problems with C standard I/O buffer flushing. - See the ChangeLog for further details. -
-- Release notes for version 6.2 are retained because they are still relevant. -

+ A configuration is available for the NXP LPC17xx to demonstrate this functionality.
inet_addr() (contributed by Yu Qiang), strndup(), and asprintf().
version.h file is now automatically generated so that C code can now be version-aware.
+ fdopen() now works with socket descriptors allowing standard bufferedC functions to be used for network communications.
+ iconfig Extensions.
+ The NSH ifconfig command can now be used to set or change the IP address (contributed by Yu Qiang)
- In addition to these new feature, several important bugfixes are included in this release correcting problems with
- dup2(), LPC17xx GPIO interrupts, LPC17xx UART2/3, the FAT file system, build issues, and strrch().

- * arch/arm/src/lpc17xx/lpc17_gpioint.c: Correct errors in logic that maps
- and IRQ number into a register bit number.
- * Makefile: Fix an error introduced in the top-level Makefile in NuttX-6.1.
- This error only shows up if you have a /tftpboot directory. Then the
- make will fail with an obscure error about not being able to stat pass2.
- * configs/lpcxpresso-lpc1768/nsh: Add an NSH configuration for the
- LPCXpresso board.
- * configs/*/ld.script: Removed 'sh_link not set for section .ARM.edix' for
- a few of the builds. In you have this warning, it can be removed with the
- following change to the ld.script file:
-
- + __exidx_start = ABSOLUTE(.);
- .ARM.exidx : {
- - __exidx_start = ABSOLUTE(.);
- *(.ARM.exidx*)
- - __exidx_end = ABSOLUTE(.);
- } >sram
- + __exidx_end = ABSOLUTE(.);
+ * lib/drivers/cc1101: Add initial, functional CC1101 wireless driver
+ (contributed by Uros Platise)
+ * arch/mips and configs/pcblogic-pic32mx: The MicroChip PIC32MX port is now
+ code complete and ready to begin testing. Unfortunately, it looks like
+ testing will be delayed due to tool issues (My PICkit 2 will not work the
+ the MPLAB debugger on PIC32; I will need to get a PICkit 3).
+ * drivers/net/e1000.c/h: A PCI-based E1000 ethernet driver submitted
+ by Yu Qiang.
+ * lib/net/lib_inetaddr.c: An implementation of the inet_addr() function
+ submitted by Yu Qiang.
+ * arch/arm/src/lpc31xx and arch/arm/include/lpc31xx: Renamed from lpc313x
+ to make name space for other famiy members.
+ * arch/arm/*/lpc31xx: Added support for the LPC315x family (untested).
+ * sched/task_exithook.c: Functionality performed when a task exits or is
+ deleted has been moved to a common file task_exithook.c. Now exit()
+ functionality (like flushing I/O and calling registered atexit()
+ functions, etc.) will be performed when a task is deleted as well.
+ * mm/: Added support for CONFIG_MM_SMALL. Each memory allocation has a
+ small allocation overhead. The size of that overhead is normally
+ determined by the "width" of the address support by the MCU. MCUs
+ that support 16-bit addressability have smaller overhead than devices
+ that support 32-bit addressability. However, there are many MCUs
+ that support 32-bit addressability *but* have internal SRAM of size
+ less than or equal to 64Kb. In this case, CONFIG_MM_SMALL can be
+ defined so that those MCUs will also benefit from the smaller, 16-
+ bit-based allocation overhead.
+ * lib/string/lib_strndup.c: Add standard strndup() library function.
+ * net/getsockname.c: Added standard getsockname() to return the local
+ address associated with a socket.
+ * lib/stdio/lib_asprintf.c: Add asprintf()
+ * configs/olimex-lpc1766stk/ftpc: Add a configuration to support
+ testing of the FTP client shell.
+ * fd/fs_fdopen.c and net/net_checksd.c: Add support so that fdopen may
+ be used with socket descriptors.
+ * net/recvfrom.c: Fix an error found in receiving small files via FTP:
+ The small file is received a buffered in the readahead buffer, then the
+ socket is disconnected. When the app calls recvfrom, the socket is
+ already disconnected and the buffered data is stranded. Now, recvfrom
+ will continue to return success after the socket is disconnected until
+ the readahead buffer is drained.
+ * olimex-lp1766stk/ftpc/defconfig: Many configurations have the MTU
+ (CONFIG_NET_BUFSIZE) set to very small numbers, less then the minimum
+ MTU size that must be supported -- 576. This can cause problems in
+ some networks: CONFIG_NET_BUFSIZE should be set to at least 576 in
+ all defconfig files. This has only been fixed in this defconfig file.
- * arch/arm/src/lpc17xx: Correct some typos/bugs in configuration of LPC17xx
- UART2 and UART3.
- * nuttx/clock.h: Replace all references to the global variable g_system_timer
- with clock_systemtimer() (currently just a macro that that returns g_system_timer).
- * lib/string/strrch.c: Would fail if the searched-for character were the first
- character in the string.
- * tools/version.sh and mkversion.c: Tools to manage a NuttX version number
- file
- * sched/clock_getutc() and lib/time/lib_time.c: Add support for 1 second UTC
- interface.
- * net/net_dup2.c and include/nuttx/net.h: The conditional compilation for
- '#if CONFIG_NFILE_DESCRIPTOR > 0' was wrong in both of these files. It should
- be '#if CONFIG_NFILE_DESCRIPTORS > 0'. This causes a dup2() failure in THTTPD
- and a failure to get a CGI page. The consequence can be a very serious bug!
- * configs/lpcxpresso-lpc1768/usbstorage, thttpd, and dhcpd: Add an USB storage,
- THTTPD web server, and DHCP server configurations for the NXP LPCXpresso board.
- * drivers/lcd/ug-9664hswag01.c and ssd1305.h: Add support for Univision UG-9664HSWAG01
- OLED with Solomon Systech SD1305 LCD controller.
- * configs/lpcxpresso-lpc1668/nx: Add a NX graphics configuration for the LPCXPRESO
- board.
- * graphics/nxglib/nxglib_nonintersecting.c: Fix some single bit errors in
- calculation of non-intersecting regions. This was causing an anomaly
- in examples/nx in column 0.
- * drivers/mtd/rammtd.c: Added a RAM based MTD driver. This RAM driver simulates
- FLASH and is useful for testing purposes.
- * arch/arm/src/arm/up_head.S: Fix backward conditional compilation. This cause
- the configs/mx1ads configuration to fail to build but does not appear to affect
- any other ARM9 build.
- * fs/nxffs: Adding a tiny, wear-leveling FLASH file system for NuttX. This
- file system is intended to be small and will have some limitations. The
- implementation is incomplete on initial checkin.
- * apps/examples/nxffs and configs/sim/nxffs: Add a test a a configuration that
- will be used to verify NXFFS.
- * fs/fat/fs_fat32.c and fs_fat32util.c: Incorpated two bugs with fixed provided
- by Sheref Younan. Thanks!
- * fs/nxffs: After a couple of weeks of testing and bug fixes, NXFSS appears
- stable and functional.

-
- * Remove clock_getutc(). It is replaces with clock_gettime(CLOCK_ACTIVETIME).
- Add other RTC related changes provided by Uros Platise.
- * arch/arm/src/stm32/stm32_flash.c: Add support for access to on-chip STM32
- FLASH; beginning of integration with NXFFS (Uros Platise).
- * arch/mips: Added directory structure for PIC32 support
- * configs/pcblogic-pic32mx: Add directory structure for PCB Logic PIC32MX board
- * apps/include: Move include/apps to apps/include. A symbolic link is created at
- build time
- * Makefile: Removed support for Pascal pcode interpreter. Support for that
- interpreter has been moved to apps/interpreter/Makefile.
- * tools/mkdep.sh: Should not report an error if there are no files on the command
- line. This happens normally in certain configurations.
- * drivers/usbhost: Sheref Younan reported an error in the error handling when
- connection to a USB device fails. In certain fail cases, the logic would try
- to free the device class instance twice, the first was okay, but the second
- caused a crash.
- * graphics/nxbe/nxbe_colormap.c: Fix error noted by Bassem Fahmy. The function
- nxbe_colormap was change to nxbe_configure... apparently "search-and-replace"
- error. This error was not noticed before because most NX platforms do not use
- colormapping.
- * arch/rgmp and configs/rgmp. Add architecture support and build
- configuration for RGMP. RGMP is a project for running GPOS and
- RTOS simultaneously on multi-processor platforms. See
- http://rgmp.sourceforge.net/wiki/index.php/Main_Page for further
- information about RGMP.
- * lib/stdio/lib_fclose.c: Must flush all buffered data when the file is closed.
- Instead, it was discarding the buffered data.
- * lib/stdio: All output stream logic was modified to support CONFIG_STDIO_LINEBUFFER.
- If standard C buffered I/O is enabled (CONFIG_STDIO_BUFFER_SIZE > 0), then this
- option may be added to force automatic, line-oriented flushing the output buffer
- for putc(), fputc(), putchar(), puts(), fputs(), printf(), fprintf(), and vfprintf().
- When a newline is encountered in the output string, the output buffer will be
- flushed. This (slightly) increases the NuttX footprint but supports the kind of
- behavior that people expect for printf.

-
- * apps/interpreter: Add a directory to hold interpreters. The Pascal add-
- on module now installs and builds under this directory.
- * apps/interpreter/ficl: Added logic to build Ficl (the "Forth Inspired
- Command Language"). See http://ficl.sourceforge.net/.
- * apps/netutils/dhcpc, dhcpcd, and tftp. If these directories are included
- in the configuration but CONFIG_NET_UDP is disable (which is not very wise),
- then a make error occurs because tools/mkdep.sh is called with no files.
- * system/free: Move Uros' custom free command from vsn/free
- * system/install: Add a new install command submitted by Uros Platise.
- * examples/rgmp. Add a placeholder for an RGMP build example.
- RGMP is a project for running GPOS and RTOS simultaneously on
- multi-processor platforms. See http://rgmp.sourceforge.net/wiki/index.php/Main_Page
- for further information about RGMP. NOTE: This is an empty example
- on initial check-in.
+ * nshlib/nsh_netcmds.c: If a network device name and IP address are provided
+ with the ifconfig command, then this command will now set the network address.
+ (Contributed by Yu Qiang).
+ * netutils/ftpc: A library to support client-side FTP.
+ * examples/ftpc: A simple add-on to the NSH. From NSH, you can start
+ this simple FTP shell to transfer files to/from a remote FTP server.
