Board is customer board, CPU is i.MX353, with MC13892.

 

Before this problem, Windows CE can suspend and resume regular, at one day, i build a trouble version OS for the board, and can't suspend. suspend process hang at function:

"extern "C" void HCD_PowerDown(DWORD hDeviceContext)"

return.

 

 

I clean the NAND flash, and re-burning old version (can suspend/resume) firmware, XLDR, e-boot, NK, but problem still exist, still can't into suspend, I'm only know some non-volatile memory like NAND-flash, eFUSEs at i.MX35 CPU, I clean all of NAND block and confirm eFUSEs does not change between suspend/resume workable board and this problem board.

 

and what i can insert debug message to any driver? I insert debug message at every  i can found driver that had "xxx_PowerDown" function, the lastest message at "void HCD_PowerDown(DWORD hDeviceContext)" function return.

 

any idea? 

 

thanks everyone.
