how to use variable in across different cores? how to debug FreeRTOS ?

[kavyamm]

Now, I am using the NUCLEO-H755ZI-Q board,  Could you share how to solve the issue of using the same (shared) variable in across different cores?

when I try to debug the code of freertos ,It is not going to debug after it enter this line  osKernelStart(); how to debug further. how to know my code is correctly working or not. (i am useing stm32cubeIDE)

Welcome to the forum.

That sounds like two separate questions. Best to keep to one question per thread.

You've already seen STM32H755Zi-Q~How to share data between cores - which was answered here.

Have you studied that Application Note?

Thank you for the response. For shared variable, I used hardware semaphore it is working .

for debugging the freertos ,I put a breakpoint for where I need.
