FreeRTOS debugging on stm32F401 is not possible

Hi everyone.

I use CubeIDE 1.10.1 and CubeMX 6.6.1 MCU stm32F401CCU6 stm32H750. StlinkV2 or J-link Ultra.

When I start debugging FreeRTOS I get stuck in the osKernelStart() -> vTaskStartScheduler-> xPortStartScheduler-> prvPortStartFirstTask-> and I stuck in my task forever but just during debugging !!!!

Without debugging program works fine. Why is it happening? Am I doing something wrong of this is a bug?

Please, can someone help me? I would be very grateful.

Hi @Walid ZRELLI​.

As a new member I cannot add links. I already watched it and searched through this site.

The problem is next. the arrows grayed out and I stuck in my task. Cannot go further. I cannot figure it out. And could you please tell me why osDelay() or taskYIELD() during debugging does not switch context. Why I cannot do step-by-step debugging?

Thanks for the response.0693W00000SvZF2QAN.png
