s3c64xx wake up question

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

 



Hi,

I am trying to get wake-up from IDLE and SLEEP working on my board based on S3C6410.

The problem I see is that once the CPU goes to SLEEP or IDLE state, it does not wake up despite configuring activity on Keypad.
I have verified the following:
1. VDD_ALIVE is powered up @1.2V
2. Dumped EINT_MASK and EINT0_MASK - reset with 0 (enable) for almost all the sources.
3. PWR_CFG is configured to be woken up for all sources (HSMMCx, RTC, KEYPAD etc)

So, not sure if have something else to verify or check.

I hope someone could provide some pointers on the problem.

Regards,
Madhvapathi Sriram
