Question

Reset MPU independently of MCU

Hello.

I want to reset MPU core(s) while MCU is running firmware. Such reset shouldn't stop MCU.

I can make electrical changes if it can be achieved with power control. Or maybe it can be possible to use PWR (or some other) registers?

Hi @alexey.b​ 

This feature is not supported on STM32MP1 mostly for reason that on software side MCU is dependent of the reset on MPU side. ( resource management and configuration)
