Hi,
I have a Pi 3b running bullseye.
I've installed a rtc-pcf8563. I've followed several sets of instructions for installing it, as nothing seemed to quite get it working, but finally it worked. It updated the time with ntp and
showed the correct time.
However, after a reboot, it's no longer working. Now the same command gives;
hwclock: Timed out waiting for time change.
Here are some commands I've tried and some file contents that ought to be relevant:
Thanks.
