Linux/AM3352: NRESETIN_OUT not functional in Deepsleep

Part Number:AM3352

Tool/software: Linux

The reset switch on my board is not triggering a reset when the device is in deep sleep. In the normal mode, it works as expected where pressing the switch asserts NRESETIN_OUT pin to low and the the device reboots immediately. While in sleep, though the NRESETIN_OUT is driven low, reset isn't observed.

Command used to enter deep sleep : rtcwake -m mem -s 120

Any leads on the root cause would be appreciated.

Thanks in advance,
