Changelog FreeRTOS kernel for MCUXpresso SDK#

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]#

Fixed#

  • Temporary workaround for FreeRTOS-Kernel upstream bug #1480: stray URL (http://files.iar.com/ftp/pub/box/bxarm-9.60.3.deb) accidentally placed outside /* */ comment delimiters on line 466 of the IAR CM33/CM55/CM85 TrustZone non-secure portasm.s files (introduced in upstream commit 78e0cc778a, PR #1195). Fixed copies are placed under portable/IAR/ARM_CM{33,55,85}/non_secure/portasm.s and the CMakeLists.txt SOURCES entries for the cm33/cm55/cm85_trustzone.non_secure IAR toolchain blocks are redirected to those copies. Revert the three CMakeLists.txt lines once the upstream fix is merged and the freertos-kernel-upstream revision is bumped past it, then delete portable/IAR/ARM_CM{33,55,85}/ from this repo.

[9.0.0_rev3]#

  • New features:

    • Tickless idle mode support for Cortex-A7. Add fsl_tickless_epit.c and fsl_tickless_generic.h in portable/IAR/ARM_CA9 folder.

    • Enabled float context saving in IAR for Cortex-A7. Added configUSE_TASK_FPU_SUPPORT macros. Modified port.c and portmacro.h in portable/IAR/ARM_CA9 folder.

  • Other changes:

    • Transformed ARM_CM core specific tickless low power support into generic form under freertos/Source/portable/low_power_tickless/.

[9.0.0_rev2]#

  • New features:

    • Enabled MCUXpresso thread aware debugging. Add freertos_tasks_c_additions.h and configINCLUDE_FREERTOS_TASK_C_ADDITIONS_H and configFRTOS_MEMORY_SCHEME macros.

[9.0.0_rev1]#

  • New features:

    • Enabled -flto optimization in GCC by adding attribute((used)) for vTaskSwitchContext.

    • Enabled KDS Task Aware Debugger. Apply FreeRTOS patch to enable configRECORD_STACK_HIGH_ADDRESS macro. Modified files are task.c and FreeRTOS.h.

[9.0.0_rev0]#

  • New features:

    • Example freertos_sem_static.

    • Static allocation support RTOS driver wrappers.

  • Other changes:

    • Tickless idle rework. Support for different timers is in separated files (fsl_tickless_systick.c, fsl_tickless_lptmr.c).

    • Removed configuration option configSYSTICK_USE_LOW_POWER_TIMER. Low power timer is now selected by linking of apropriate file fsl_tickless_lptmr.c.

    • Removed configOVERRIDE_DEFAULT_TICK_CONFIGURATION in RVDS port. Use of attribute((weak)) is the preferred solution. Not same as _weak!

[8.2.3]#

  • New features:

    • Tickless idle mode support.

    • Added template application for Kinetis Expert (KEx) tool (template_application).

  • Other changes:
