Hi,
I have a problem with the suspend wake-up procedure. I'm using the sam9263 with wince 6.0R2. I'm using a key button to wake-up the system.
I put in suspend mode the system using the menu start->suspend,
1) if I wake-up the system in about 30 seconds everything works fine
2) if I wake-up the system after 30 seconds the system hangs
KeyPadPowerOff customclass
KeyPadPowerOff
resetting RTT to delay rollover
BSPPowerOff
+SOCSaveAndDisableAllIntrBeforeSuspend()
SOCPioSaveAndDisableAllIntrBeforeSuspend()
+SOCPioControllerIntrEnable()
OALPowerWakeSource enable 17

SUSPEND CPU

+SOCRestoreAllIntrAfterSuspend()
+SOCPioRestoreAllIntrAfterSuspend()
BSPPowerOn
-----system hangs -----

any idea? (I have disabled all the timers in the PM power module)
thanks

Hi,

Did you ever figure this out? I'm experiencing the same problem at the moment.

This could be due to the data loss in SDRAM during suspend period.
To confirm it, you can try disabling all the SDRAM and PMC configure code in PLATFORM\AT91SAM9263EK\SRC\OAL\OALLIB\asmpower.s to let SDRAM and all the clock run as normal during suspend.

And see whether you still have this problem or not.
