when I put break point right after the vTaskDelay with gcc compiler (00) optimization flag enabled, it doesn’t hit the breakpoint. Same code works well with the optimization (-O1) flag.
Apparently stack and heap is not an issue here.
Below is the code snippet :
Project is generated using cubemx for the mcu stm32H753.
below is the FreeRTOSConfig.h file

what could be an issue and how to resolve this without changing the gcc compiler optimization?
I’ve seen your completion edit of the initial post after posting …
