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?
Thanks,
Ashik P.
Suppose don’t need to enable for regular battery.
Thanks @ShaneCCC
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.
Why is this difference?
Could you dump the device tree to compare to figure out if any software configuration cause the different.
sudo dtc -I fs -O dts -o extracted_proc.dts /proc/device-tree
Hi Shane,
I have attached both files.
dts_Jax.dts (361.5 KB)
dts_JaxI.dts (362.7 KB)
What do you mean checking VCC_RTC on industrial SOM and Xavier devkit? Which point did you probe? What is the carrier board for both?
