Hi. I am using iMX53 processor which runs on wince 7.I am using imx53 qsb BSP provided by adeneo.

I am working on power management which comes into effect when our product is battery operated.

 

But I'am facing issues while using setsystempowerstate api to systemidle. I am getting an error saying file not found and the powerstate return says -1 (unknown state).

Whereas useridle is working. When put to suspend my display is not going off . I really doubt if it has gone to suspend state, but I am getting all debug messages rather retail messages that I have put in to check if it passes all levels.

And I found that there are no power management function implemented for USB, FEC drivers. Whereas I need those drivers to go-to sleep when they are not used.

Are these drivers not implemented with power manager initially?? should i customize?

 

Regards

Sriram
