S5PC100 suspend to ram debugging

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

I am trying to implement/test the "Suspend to RAM" feature on a
smdkc100 (processor S5PC100) based board. I am unable to see ant debug
messages when I do the following:

echo "mem" > /sys/power/state

The debug console is assigned to /dev/ttySAC0. My guess is that the
pm_prepare() function in mach-s5pc100/pm.c should  be implemented in
this case to view the debug messages.
Can anyone please guide me as to how this can be done? Also, are there
any modifications with respect to u-boot for resuming from the suspend
state in this case?

Thanks.

Best regards,
Shrirang.
