Re: why this API (SetSystemPowerState) can not change the system power state??

Hi, Michel

Could you tell me what is the IClass ID of the usb host driver?

I want to let the usb host driver keeping power on when the system get into
suspend mode. but I had not any better idea now.Maybe you can give me some
advice. Thanks.

Suspend/Resume is board (hardware) specific. You'd have to debug exactly
where it stops and ask a targeted question (with all necessary info like
BSP used, hardware used, GPIO setup, interrupt (wake source) setup etc).


Good luck,

Hi, Michel
Could you help me again? I got another problem, and maybe this problem
has relationship with the PM too.

When my system get in suspend mode, I can not resume it. This function,
OEMPowerOff(), has been called, and I used a GPIO interrupt as a wake up
source to wake up my system, and the system can recognize this wake up
source, those functions, XXX_PowerUp, has been called too, but not all
those functions had been called. Could you tell me what and how we should
do when we want to wake up our system?

Could you give me some advice? Thank you.

Best Regards

Ricky
