STN32H747 Dual Core - only reset 1 core

I can perform a software system reset but what I want to do is have the M7 reset the M4 cpu - is there a way?

I have always written my own bootloader so the product can have firmware upgraded in the field.

With the Dual Core - the M7 will be updating the flash memory space for the M4 and I need to be able to have it start back at its reset vector.

Thanks

    If I read the documentation properly - it states that CPU1 can software reset CPU1 and CPU2 can software reset CPU2. I do NOT believe that it states CPU1 can reset CPU2 via that process.

    If my statement is correct - than it does not answer the question.

    Thanks for trying.

    I did not notice your request to reset the other CPU. I scanned RM0399 and did also not find anything.
