Hi All,

I am working on Power Management on IMX8QM-MEK + Android Automotive.

I needs to know what are possible way to suspend and resume the Application Processor (AP) by using M4 MCU (M4F).

Currently,

I am trying with System Controller API, But, there is no scope.

Thank you Igor for the reply.

I followed already. But, I found so many problem from here,

1. Given link for Linux (L4.14.78) and I am using Android (L4.14.98)
2. Given link for IMX8QXP and I am using IMX8QM-MEK
3. Power Mode Switch Application is difference
4. Unable to find out wakeup - /sys/bus/platform/devices/90000000.rpmsg/power/wakeup

I tried already but, there is no scope. Please provide is there any other way to control the Application Processor from M4 MCU.

Thanks & Regards,
