Hi Suren

I find in the academy of RTC usage, which need rtcwake source to move the device from deep sleep mode to normal operation.

But here is customer usage and want to check with you.

The control board based on AM62 will face the power off for more than 1 month. For this scenario, customer want to know if they can provide a battery and a crystal vibration to RTC module, RTC module can be running during the power off state and record the timestamp when power on. 

If this solution can not be feasible, they will need an external RTC silicon + battery +  crystal vibration to implement this function.

Providing backup power to retain the RTC on the Am62x is not a tested or support option.

After Power-up the RTC module can be configure and using the 32K clock can increment the time.
