The change log associated with the release is available here. Unreleased changes after this release are available in SVN. - These unreleased changes are listed here. + These unreleased changes are also listed here.
- The 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: + The 6.2 NuttX release includes several new features:

apps/ directory build system would not handle Windows-native toolchains due to obscure path formatting issues.
+ Support for NXP LPCXpresso LPC1768 board on the Embedded Artists base board.
+ The Code Red toolchain is supported under either Linux or Windows.
+ Verifed configurations include DHCPD, the NuttShell (NSH), NuttX graphis (NX), the NuttX OS test, THTTPD, and USB mass storage device.
version.h file is now automatically generated so that C code can now be version-aware.
- Many additional changes were made in the 6.1 release for another major architectural change: - NuttX will now build as a seperately linked micro-kernel. - In this build option the RTOS builds as a kernel, applications build separtate 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: -
-/bin directory.
- user_initialize() interface has been removed.
-
- And several bugfix are included.
- This includes chagnes associated with SD drivers, openddir(), signed 8-bit types (int8_t), and USB serial device. See the ChangeLog for details.
+ 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().
+ See the ChangeLog for more details.

Submited by - Decio Renno. - * Initialization for the CONFIG_APPS_DIR is now supported during the - earlier, 'context' build phase. - * arch/arm/src/lpc17_gpioint.c: Finish coding of the LPC17xx GPIO - interrupt logic. - * net/netdev_unregister.c: Add capability to un-register a network - device. - * drivers/mmcsd/mmcsd_sdio.c: extra effort to correctly handle cases - without the SDcard (but one issue still exists in STM32) - * arch/arm/src/stm32/stm32_tim.*: Added basic timer support TIM1..TIM8 - with output PWMs and interrupt logic - * config/vsn/src: added basic support for Sensor Interface (GPIO and - PWM Power Output, and the sif utility program) - * fs/: Reorgnize header so that file systems can be built outside - of the nuttx source tree - * apps/namedapp/binfs.c: Create a tiny filesystem that can be used - to show the internal named apps under /bin. - * fs/fs_opendir.c: Correct an error that occurs when a file system is - mounted in the root directory. This was discovered while mounting - the named app's /bin directory. - * lib/: Move all source files into a subdirectory of lib/ named after - the header file in which the library function is prototyped. - * sched/ and lib/pthread/: Move pthread attribute-related interfaces - from sched/ to lib/pthread where they more appropriately belong. - * sched/ and lib/semaphore/: Move some semaphore-related interfaces - from sched/ to lib/pthread where they more appropriately belong. - * syscall/: The beginnings of an optional syscall kernel interface. - * tools/mksyscall.c: Add a tool that will auto-generate syscall proxies - and stubs from a comma-separated-value (CSV) data file. - * arch/arm/src/cortexm3/mpu.h: Add a header file describing the Cortex-M3 - MPU registers. - * Numerous modifications to the build system. Various people have reported - build problems since the re-organization and release of NuttX-6.0. I am - unable to replicate the build problems in my environment, but the changes - have be incorporated in hope of correcting the build issues in other - environments. - * drivers/i2c/st_lis331dl.c: I2C-based driver for the LIS331DL MEMS - motion sensor. Contributed by Uros Platise. - * Makefile: The NuttX build system will now supported building NuttX as two - separately linked images: (1) a kernel-mode RTOS image, and (2) a user- - mode application image that communicates to the RTOS kernel via system - calls. A lot more still must be done. - * user_initialize(): Eliminated the user_initialize() initialization hook. - It is difficult to maintain and redundant: Board level initialization - an up_initialize() provide the same kind of capability. - * arch/*/include/*/type.h: On some compilers, char defaults as unsigned. - Explicitly add signed to integer types if signed is what is required. - * arch/*: For all architectures -- Global register state save structure - (usually called current_regs) should be marked volatile; Added general - capability to support nested interrupts (not fully realized for all - architectures). - * sched/task_create.c: Add support for starting kernel-mode thread. - * drivers/usbdev/usbdev_serial.c: Fix reported by Sheref Younan. USB - was being reset after serial driver was closed. As a result, you could - no reopen the serial driver. - * configs/lpcxpresso-lpc1768: Add a board configuration for the Embedded - Artists LPCXpresso LPC1768 board. - -apps-6.1 2011-04-10 Gregory Nutt <spudmonkey@racsa.co.cr> - - * Creation of auto-generated header files now occurs during the context - build phase. - * Added sdcard insert and eject, nsh command '?' and some code remarks - * Renamed nuttapp to namedapp - * namedapp/binfs.c -- Create a tiny filesystem that can be used - to show the internal named apps under /bin. - * Numerous fixes to build system required to support building with native - Windows toolchain. - -pascal-2.0 2009-12-21 Gregory Nutt <spudmonkey@racsa.co.cr> - - * Updated to use standard C99 types in stdint.h and - stdbool.h. This change was necessary for compatibility - with NuttX-5.0 (any beyond). - -buildroot-1.9 2011-02-10 <spudmonkey@racsa.co.cr> - - * configs/arm926t-defconfig-4.3.3: update arm926t-defconfig-4.2.4 - * configs/arm926t-defconfig-nxflat: NXFLAT-only configuration for - arm926 - * toolchain/gdb/gdb.mk - Remove ncurses dependency from gdb_target target. - * toolchain/gdb/gdb.mk - Added --disable-werror to GDB configuration line. - GDB 6.8 won't build because the tarbal was released with -Werror enabled and - the build stops on the first warning. - * Add support for Freescale m9s12x using binutils 2.18 and gcc 3.3.6 and - patches available from http://www.msextra.com/tools courtesy of James - Cortina. Add configs/m9x12x-defconfig-3.3.6. -- -
