Hi @GRatt.1
Please refer to all documentation related to Low Power management on MP1 :
Wiki : https://wiki.st.com/stm32mpu/wiki/Power_overview
Then you can find a sample project in CubeFirmware Package under Projects\STM32MP157C-DK2\Applications\OpenAMP\OpenAMP_TTY_echo_wakeup
See scenario number 2 : System Run Mode with CA7 in CStop and CM4 in CRun
Which looks to be the one you are interested in. ( A7 wakeup from M4)
Note that shutdown/restart A7 while M4 is running is not supported.
