+ The MPU port is not supported in this revision number.
+ The documentation for the static allocation functions in the header files has not yet been updated for this revision.
Kernel updates:
+ Simplify the static allocation of objects implementation.
+ Introduce configSUPPORT_DYNAMIC_ALLOCATION in addition to the existing configSUPPORT_STATIC_ALLOCATION so FreeRTOS can be built without providing a heap at all.
Demo application updates:
+ Update the demos to take into account the new configSUPPORT_DYNAMIC_ALLOCATION constant.
+ Add an MSVC demo that only uses static allocation, and does not include a FreeRTOS heap.
+ Update the MSVC project to use both configSUPPORT_STATIC_ALLOCATION and configSUPPORT_DYNAMIC_ALLOCATION.
+ Update the MingW project to use only configSUPPORT_DYNAMIC_ALLOCATION.
+ Added xTaskAbortDelay() function, which causes a task to exit the Blocked state even before the timeout has expired or the event the task is waiting for has occurred.
+ For efficiency and code size reasons on some architectures, replace many instances of "== pdTRUE" with "!= pdFALSE".
+ Added xPortIsInsideInterrupt() to RVDS ARM CM4F port - the same will get added to other ports in time.
Demo application code:
+ Added first pass Microchip CEC1302 demo for Keil.
+ Harden the new StaticAllocation.c standard demo tasks against integer promotion rules causing problems on 16-bit architectures.
Add a member to the TaskStatus_t structure that is used to return the base address of the stack used by the task being queried.
Add xTaskGetTaskHandle() that allows the handle of a task to be looked up from the task's text name.
Continue to document the macros that allow RTOS objects to be created using statically allocated memory.
Introduced vApplicationDaemonTaskStartupHook(), which allows initialisation that that needs to be executed after the scheduler has been started to be executed from the RTOS daemon task.
Call prvResetNextTaskUnblockTime() in xTaskResumeAll() if a task is moved from the pending ready list - this can prevent an unnecessary wake from sleep mode if a task is unblocked by an interrupt while in a low power tickless state.
Move structures used for static allocation of tasks and queues into FreeRTOS.h from their individual API header files.
Add SAME70 Xplained Atmel Studio project.
Update SAMV71 Atmel Studio project to use Studio 7.
Revert some changes to GenQTest.c standard demo task which only function correctly when a queue registry was used.
+ Introduced xTaskCreateStatic() to allow tasks to be created without any dynamic memory allocation.
+ When a task notification is used to unblock a task from an ISR, but the xHigherPriorityTaskWoken parameter is not used, then pend a context switch to occur during the next tick interrupt.
Demo application changes:
+ Updated TaskNotify.c to test the case where a task is unblocked by an ISR, but does not use its xHigherPriorityTaskWoken parameter.
+ Updated the Win32 MSVC project to test statically allocated tasks being created and deleted.
+ Introduced StaticAllocation.c standard demo task.
Bug fix - issue introduced in V8.2.2 when the current timer list is empty and the overflow timer list is not empty.
Add PIC32MZ EF (floating point) support and update the MZ demo project to test the flop context switching.
Improve efficiency of the stack overflow checking.
Add CLI to RX71M demo.
General tidy up of new RZ and RX projects - including ensuring the UART driver copes with 0 length strings.
Add stack overflow checking to the [old] PIC24 demo.
Add additional asserts into timers.c.
Trivial changes and changes in demo applications:
RX113 IAR project is not building and running.
Make FreeRTOS_SetupInterrupt() and FreeRTOS_ClearInterrupt() weak symbols in the Zynq SDK repository.
Correct typo in the port layer comments that was cut and paste into multiple files.
+ The timer task now blocks indefinitely if there are no timers active, allowing eTaskConfirmSleepModeStatus to return eNoTasksWaitingTimeout when configUSE_TIMERS is set to 1.
+ The next unblock time is calculated automatically after a task unblocks when waiting for a notification, allowing deep sleep to be entered earlier.
Remove redundant global definition vPortInstallFreeRTOSVectorTable from the GCC ARM_CA9 portASM.S file.
Ensure correct sequence of start up sequence when the Windows port is used on multi-core Windows machines by starting one thread in the suspended state.
Move initialisation of xNextTaskUnblockTime to the function that starts the scheduler, rather than from where the variable is declared - this fixes a compiler warning in newer IAR compilers.
Fix "elif (SELECTED_PORT == PORT_MICROCHIP_PIC32MX || PORT_MICROCHIP_PIC32MZ)" in the FreeRTOS+Trace trcHardwarePort.h header file.
+ Added vTimerSetTimerID() to compliment vTimerGetTimerID(). Now the timer ID can be used as timer local storage.
+ Updated comments and added some additional assert() calls.
Win32 port:
+ Some changes to allow easier 64-bit builds
PIC24/dsPIC port:
+ Added NOP after disable interrupt instruction.
Add a "query heap" command to the standard sample CLI commands.
Remove casting from configMAX_PRIORITIES setting in Win32 simulator demos as it was preventing a clean build.
Source code changes.
General tidy up and addition of assert points.
+ Fix a few compiler warnings.
+ Add TickType_t specific critical sections so critical sections are not used when accessing the tick count in cases where the access is atomic (32-bit tick count, 32-bit architecture).
Change INCLUDE_xTimerPendFunctionCallFromISR to INCLUDE_xTimerPendFunctionCall
Update event group trace macros to match the new trace recorder code.
Ensure parameter name consistency by renaming any occurrences of xBlockTime and xBlockTimeTicks to xTicksToWait.
Continue work on GCC/RL78 port - still a work in progress.
Adjust how the critical section was used in xQueueAddToSet.
Replace #define types with typedefs.
Rename all typedefs to have a _t extension.
Add #defines to automatically convert old FreeRTOS specific types to their new names (with the _t).
Reset the expected block time variable when a task is suspended or deleted in case the value held in the variables was associated with the task just suspended or deleted.
