Hi,

I am implementing suspend/resume for a PXA 270 based system, Windows CE 5.0.
At this stage, OEMPowerOff() is stubbed, so no real sleep is taking place.

I have the following drivers enabled: USB host, LCD, and DM9000 network,
connected directly to CPU.

In release version, pressing suspend flickers the screen, and hangs a USB
mouse for a relatively long period of time (10-20 sec)(why is that?), but
everything comes back online eventually. Including network...

In Debug, with KITL over DM9000 enabled, after resume:
1) Screen comes back on, but the "Start->Suspend" menu remains selected
2) KITL is ACTIVE, I can do a debug of the USB resume process.
3) USB performs all the resume actions.
4) The usb mouse doesn't work (no cursor movement on screen)
5) Activation of applications via KITL doesn't show anything on the display.

It looks like GWES is stuck, or some other part of the system prevents it
from operation.
Any help would be most welcome.

Thanks
Andrey.

Could be something in the display driver. What you are describing is
consistent with the display buffer being unchanged from before suspend,
meaning that the display driver never reinited and GWES never did a redraw.

This could be it, if not for the fact that I get this problem with two
display drivers -
one on PXA270, and another on Marathon 2700G accelerator.
The drivers are completely different, but the problem is the same....

Thanks,
Andrey.

maybe you could check if display driver is in cause by putting the Stub
display driver and using cerdisp for user interactivity, and check if you
have the same behavior.
