I am working on Rock 3 A (8 GB and 128 GB) Ubuntu 20.04 LTS OS (rock-3a-ubuntu-focal-server-arm64-20220601-1033-gpt.img.xz). I’m facing some issues with RTC.
Initially I connected using POE with internet and date, time has been fetched automatically. Later I connected the RTC battery on the module and disconnected the internet connection. It was working good only, till I reboot the device. Once I rebooted without internet, date and time changing to old. I am checking “timedatectl” to check these details.
Could you please help me with this issue?
Thanks in advance.
