I want to use a regular battery instead of rechargable/cap for RTC. Going through other topics i found dts regarding the RTC battery is present in /hardware/nvidia/platform/t19x/galen/kernel-dts/common/tegra194-spmic-p2888-0001.dtsi.
backup-battery node status is in disabled condition right now. Do i have to make any changes to this for supporting regular battery?
One observation i had was,
When i checked vcc rtc on Jetson AGX Xavier Industrial SOM and Jetson AGX Xavier devkits (flashed default images).
On JAXindustrial → vcc rtc is 1.2v and
on JAX → vcc rtc is 2.9v.
