I am using iMX53 processor which runs on wince 7.I am using imx53 qsb BSP provided by adeneo.</P><P>I am working on power management which comes into effect when our product is battery operated.</P><P></P><P>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).</P><P>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. </P><P>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.</P><P>Are these drivers not implemented with power manager initially?? should i customize?</P><P></P><P>Regards</P><P>Sriram</P></BODY></HTML> Wed, 21 May 2014 08:47:11 GMT https://community.nxp.com/t5/i-MX-Processors/power-management/m-p/302133#M38200 srirammadhu 2014-05-21T08:47:11Z Re: power management https://community.nxp.com/t5/i-MX-Processors/power-management/m-p/302134#M38201 <HTML><HEAD></HEAD><BODY><P>Deactivated user, can you please comment on this topic?</P></BODY></HTML> Wed, 21 May 2014 12:54:31 GMT https://community.nxp.com/t5/i-MX-Processors/power-management/m-p/302134#M38201 jamesbone 2014-05-21T12:54:31Z
