AM3352: RTC-only mode (low power mode)

Seo SeungCheol

Part Number: AM3352

Hello TI team,

I have a question about low power mode.

I saw that AM62 do not support RTC-only mode at other forum.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1127716/am623-rtc-only-mode-power-consumption?tisearch=e2e-sitesearch&keymatch=rtc%25252525252520mode#

1) At AM3352 and latest SDK, Is RTC-only mode supported?

I entered the standby and deepsleep0 mode by typing 'echo standby > /sys/power/state' and 'echo mem > /sys/power/state'.

2)Then, How can enter RTC-only mode?

Please check.

Thank you.

Hello Kallikuppa,

Currently, our custom boards do not have an RTC.
We are going to add RTC to our new board.

Before that, we want to know the software way to enter RTC-only mode.
And we want to measure power consumption of RTC-only mode with BeagleBone Black.

Please refer.

Thank you.
