* Test features that are backported from version FreeRTOS 9.0.0.
|
|
*
|
|
* 1) Test backported timer functions
|
|
* - xTimerCreateStatic(), vTimerSetTimerId(), xTimerGetPeriod(), xTimerGetExpiryTime()
|
|
* 2) Test backported queue/semaphore functions
|
|
* - xQueueCreateStatic()
|
|
* - xSemaphoreCreateBinaryStatic(), xSemaphoreCreateCountingStatic(), uxSemaphoreGetCount()
|
|
* - xSemaphoreCreateMutexStatic(), xSemaphoreCreateRecursiveMutexStatic()
|
|
* 3) Test static allocation of tasks
|
|
* - xTaskCreateStaticPinnedToCore()
|
|
* 4) Test static allocation of event group
|
|
* - xEventGroupCreateStatic()
|
|
* 5) Test Thread Local Storage Pointers and Deletion Callbacks
|
|
* - vTaskSetThreadLocalStoragePointerAndDelCallback()
|
|
* - pvTaskGetThreadLocalStoragePointer()
|
|
*
|
|
* Note: The *pcQueueGetName() function is also backported, but is not tested in
|
|
* the following test cases (see Queue Registry test cases instead)
|
|
* For more details please refer the the ESP-IDF FreeRTOS changes documentation
