Can we denied access of a peripheral for one of the CPU on the stm32h7 ?

Hi,

I am working on the dual core stm32h7 and I wonder if we can prevent one CPU to have access to a peripheral enabled by the other CPU.

There is a way to do this without using MPU protection on the peripheral registers ?

No

The FPB/DWT might be more amusing than the the MPU...

Thanks for your anwer !

I'm not sure FPB/DWT can help in my case as i'm not looking for a way to detect a bug ... I want to prevent unwanted access on a peripheral by the CPU which is not responsible of this peripheral to develop a safety mechanism.
