I port FreeRTOS to a new CPU.And it can run in simple 2 tasks which have the same priority using preemption.
Now I use vSemaphoreCreateBinary to create a Semaphore to let 2 tasks giving and taking Semaphore.But run fail when vTaskStartScheduler()
xTaskCreate( vTestTask, "Task 1", configMINIMAL_STACK_SIZE, (void *) &task1id,tskIDLE_PRIORITY + 2, NULL );
xTaskCreate( vTestTask, "Task 2", configMINIMAL_STACK_SIZE, (void *) &task2id,tskIDLE_PRIORITY + 2, NULL );
vSemaphoreCreateBinary( xSemaphore );
if(xSemaphore != NULL)
vTaskStartScheduler(); // FAIL HERE
