Hi,

 

I set USB OTG to peripheral mode and to run some USB test.

 

About the suspend mode test.

 

When the host enter S3, the device (iMX7s) shall enter suspend mode too.

 

But my device still stay in run mode.


My question is if usb driver received suspend signal from host, can it make whole system enter suspend mode (suspend to ram) or just itself will enter suspend mode?

 

Thank you for your help.
