With AM335X android, I am facing an issue with suspend mode with my hardware and am seeing the same with the EVM as well.
I am finding that if USB stick is connected to the host port (in the EVM), the device does not go into suspend mode.
The screen goes blank, but the device has not gone into suspend mode (seen from the logs in the serial port).
Looks like some service is holding the wake lock when USB stick is inserted, hence preventing the device going into suspend.
Is this expected behaviour?
