Dear Kevin,
I recently checked out the latest PM branch from your git repository
and put it on the Beagleboard (B5). I have been largely able to
reproduce the results others have reported on this PM thread, but I
believe my CORE and PER powerdomains are not hitting RET or OFF.
I think this based on the following:
after I
echo 1 > enable_off_mode
echo 1 > sleep_while_idle
echo mem > state
Suspending starts but upon resume I see the following:
...
Powerdomain (core_pwrdm) didn't enter target state 0
Powerdomain (per_pwrdm) didn't enter target state 0
Could not enter target state in pm_suspend
looking at debug/pm_debug/count/
I see that only the core_pwrdm and per_pwrdm have 0's next to OFF: and
RET:
Based on the thread, the resolution seems to be to disable USB and
upgrade u-boot. I think I have done both. My u-boot is 2009.03-rc2
from Steve Sakoman's tree, and I have disabled USB support in my
Kernel build. Is there something that I am overlooking? Also, I'm
curious if the two powerdomains linked (i.e. I need to fix PER before
CORE will shut off or vice versa).
Nick
