I am difficulty setting up RTC on orin developer kit using Jetpack 5.0.2. I modified the 50-udev-default.rules but the problem still persists

hwclock from util-linux 2.34
System Time: 1675831391.280769
Trying to open: /dev/rtc0
Using the rtc interface to the clock.
Last drift adjustment done at 1675830560 seconds after 1969
Last calibration done at 1675830560 seconds after 1969
Hardware clock is on UTC time
Assuming hardware clock is kept in UTC time.
Waiting for clock tick…
hwclock: select() to /dev/rtc0 to wait for clock tick timed out
…synchronization failed

I checked the related posts at

Second one mentions to add a patch but I do know where to add this, can you please provide further instructions?

thanks,
Anil

Have successfully done this. Requires building custom Kernel and then replacing it in /boot

Thanks, this problem doesn’t seem to exist anymore with the new jetpack 5.1.
