how to switch to power state 0 when wake up from suspend mode

Huai Hellen

Hi, all

I now tested the suspend/wakeup for evm2 board. when pressed pwr_on button, it will enter suspend state. And output the below debug message

"kernel IOCTL_POWER_SET setting state 3"

and when pressed the pwr_on button again, it will wakeup, and output the below debug message

"kernel IOCTL_POWER_SET setting state 2"

My question is how to directlly switch to power state 0 not 2 when wake up, that is output the below debug message:

"kernel IOCTL_POWER_SET setting state 0"

I believe this is the behavior of the default power manager. In order to do what you want you will have to make a copy of PM from WinCE public code and customize it. See file pwstates.cpp drivers/pm/pdd/default

Hi,

In the power management, whenever there is a wake-up event occur you call "SetPowerState(D0);"
