Stm32H747I-DISCO Share Peripherals

[DMazz.1]

Hi 

Is it possible to share some peripherals between cores?

My goals is to share the SD card  trought CM7  and CM4 using hardware semaphore for the access(one SD hardware but both cores can write and read on it sharing the SD pins).

Using Stm32CubeIDE i have seen that for some peripherals  is possible flag both processors,decide who of those have to initialize it, but both can use it(as my understanding).

I have tried several time with the usart as well but right now i am stuck on this problem.

Is it possibile do that?

Is there some examples?

Thanks in advance
Best Regards
