Hi, I am facing a Hardfault problem. And I trace it and find out it is caused by the last line of the xPortStartScheduler function which should not be executed in normal cases. I still have no idea how it goes to the last line. Here are some pics: Last line of xPortStartScheduler and Register Info …

I’m pretty sure that osDelay just wraps vTaskDelay. That shouldn’t cause any problems. But did you define configASSERT and enabled stack checking ? See FreeRTOS - stacks and stack overflow checking
