VDD1 voltage after resume from idle

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

 



Hi,
 
I am facing a strange problem on OMAP3EVM after resuming from idle.
When using OPP5, the VDD1 voltage ramps to 1.35V.
 
However, when i go thru the idle/wakeup cycle, the voltage never
ramps back to 1.35V but stays at 1.20V.
 
I don't notice many changes in smartreflex.c since 2.6.31-rc7 but
this problem is not observed there. Actually, here the voltage
did not drop during suspend at all.
 
While I continue to debug, any suggestions?
 
Best regards,
Sanjeev
