i.MX8M Nano - M7 Co-processor functionality

[evancornell]

Is it possible for the M7 core within the i.MX8M Nano to access the SD card directly and power down the A53 cores?

If so, are there any documents or example code to show how to do this?

Hello @evancornell 

Please refer to this AN13400 i.MX 8M Low Power Design By M Core Running In System
Suspend.

The information there is helpful.
