OMAP 3 EVM TMDXEVM3503 "/sys/power/state" standby problem

Hi,

I am a newbie using OMAP3EVM board with Linux PSP Revision 1.0.2

Board Name : Mistral TMDXEVM3503

In power management phase of the work, I simply tried to use cpuidle as follows:

echo -n "4" > /sys/power/cpu_idle_deepest_state (I tried for "2" and "3" state and also tried "mem" arguments instead of standby)
echo -n "standby" > /sys/power/state

After this the system suspends; lcd goes off power consumption reduces etc.
Then when a key is pressed the system cannot wake neither with pressing keys nor with touchscreen.

If aanyone inform me about the problem, I will be very pleased.

Thanks

Yunus
