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)

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.

Welcome to the forum.

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

How to write your question to maximize your chances to find a solution.

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

Have you studied that Application Note?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
