Kernel source changes:
- Added xTaskNotifyStateClear() API function.
- Added the GCC Cortex-R port (existed for a while) into the main download.
- Improved the IAR RL78 port's handling of different memory model combinations.
- Removed some compiler warnings in heap_5.c.
Demo app changes:
- Added example use of xTaskNotifyStateClear() to the TaskNotify standard demo tasks.
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.
- Complete the demo projects for the RX113 using IAR, GCC and Renesas compilers by including a basic UART CLI.
Standard demo tasks:
- Add some volatile qualifiers to variables in IntQueue.c.
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.
+ Added Renesas RXv2 port for IAR.
Demo apps:
+ Demo/Rename the CORTEX_R4F_T_GCC_IAR_ARM directory to just Rename the CORTEX_R4F_T_GCC_IAR.
+ Add IAR project for the RX113.
+ Add RX231 e2studio projects for the RX231.
- Remove configASSERT() if a queue cannot be created, malloc failed hook will be called anyway.
Demo apps:
- RZ/T blinky demo working, but still lots to do to improve the port.
FreeRTOS+Trace:
- Add trace macros for task notifications.
- Update to the latest trace recorder library.
Demo projects:
- Only include the CLI command to show run time states if configGENERATE_RUN_TIME_STATS is set to 1.
- Back out changes that allow mutexes to be given from a semaphore after tests showed issues that would not be fast to fix.
Demo projects:
- Update the Microblaze Kintex 7 project and BSP to use version 2015.2 of the Xilinx SDK.
Zynq ZC702 demo application:
Update the memcpy, memset and memcmp implementations so they don't err with -O3 optimisation.
Update to use the 2015.2 version of the SDK.
Kernel changes:
- Remove an assert that was preventing xQueueSendFromISR() being used to give a mutex from an ISR (mutexes cannot be given using xSemaphoreGiveFromISR()).
- Introduce xTaskNotifyAndQueryFromISR() as the interrupt safe version of xTaskNotifyAndQuery().
Common demo task changes:
- Update IntSemTest.c to prove the theory that it is safe to give a mutex type semaphore from an interrupt using xQueueSendFromISR() instead of xSemaphoreGiveFromISR().
- Update TaskNotify.c to test the new xTaskNotifyAndQuery() from ISR fuction.
Add additional NOPs as required by hardware manual.
Microblaze:
Previously a task inherited the exception enable state from the context from which xTaskCreate() was called. Now tasks all have exceptions enabled if they are enabled in the hardware.
Windows/GCC:
Improve the implementation of portGET_HIGHEST_PRIORITY.
Common code:
Simplify the pointer use in xQueueGenericCreate()
Demo apps:
Remove jpg images that were used to create web pages.
Fix capitalisation issues in some demos where some header files are incldued with the wrong case, preventing building on Linux.
Remove the Microblaze demos that are using obsolete tools.
Update main_blinky for the Windows port demo to include a software timer example.
Windows port: Add code to ensure Windows threads are truely suspended before resuming another thread.
Typo correction to the task notification standard demo task.
Correct case of some include file names to fix build issues on Linux.
+ 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.
Update WinPCap NetworkInterface.c for FreeRTOS+UDP to correctly store a pointer to the network buffer structure at the beginning of the network buffer.
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.
