++ 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. +

+nuttx-6.2 Release Notes:
The 6.2 NuttX release includes several new features:

STATUS: - This port is complete but not stable with timer interrupts enabled. - There seems to be some issue when the stack pointer enters into the indirect IRAM - address space during interrupt handling. - This architecture has not been built in some time will likely have some compilation - problems because of SDCC compiler differences. + This port is has completed all basic development, but there is more that needs to be done. + All code is complete for the basic NuttX port including header files for all AT32UC3* peripherals. + The untested AVR32 code was present in the 5.12 release of NuttX. + Since then, the basic RTOS port has solidified: +
- QEMU/Bifferboard i486. - This port uses the QEMU i486 and the native - Linux, Cywgin, MinGW the GCC toolchain under Linux or Cygwin. -
-- STATUS: - The basic port was code-complete in NuttX-5.19 and verifed in NuttX-6.0. - The port was verified using the OS and NuttShell (NSH) examples under QEMU. - The port is reported to be functional on the Bifferboard as well. - This is a great, stable starting point for anyone interest in fleshing out the x86 port! -

++ RGMP. + RGMP stands for RTOS and GPOS on Multi-Processor. + RGMP is a project for running GPOS and RTOS simultaneously on multi-processor platforms + You can port your favorite RTOS to RGMP together with an unmodified Linux to form a hybrid operating system. + This makes your application able to use both RTOS and GPOS features. +
++ See the RGMP Wiki for further information about RGMP. +
++ STATUS: + This initial port of NuttX to RGMP was provided in NuttX-6.3. + This initial RGP port provides only minimal driver support and does not use the native NuttX interrupt system. + This is a great, stable starting point for anyone interest in working with NuttX under RGMP! +
++ PIC32MX460F512L. + A port of NuttX to the PIC32MX460F512L is underway. + This port uses the PIC32MX board from PCB Logic Design Co. + The board is a very simple -- little more than a carrier for the PIC32 MCU plus voltage regulation, debug interface, and an OTG connector. +
++ Development Environment: + This port uses the LITE version of the PIC32MX toolchain available + for download from the MicroChip website. +
++ STATUS: + This port is in its very earliest stages -- most just header file development. + Stay tuned for future releases including verified PIC32 support.
- There are partial ports for the TI TMS320DM270 and for MIPS. -

-nuttx-6.3 2011-xx-xx Gregory Nutt <spudmonkey@racsa.co.cr> +nuttx-6.4 2011-xx-xx Gregory Nutt <spudmonkey@racsa.co.cr> - * 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-chp 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-6.3 2011-xx-xx Gregory Nutt <spudmonkey@racsa.co.cr> - - * 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.
