[fedora-arm] Re: Not finding RTC with a different spin?

Use the pool Luke!

Install chrony (an NTP-like server). By default it uses the NTP POOL servers *

You can have milliseconds precision, without the drift of a RTC. 

Perhaps syncing with you other π with GPS/PPS over NTP -- join the pool.

I have a Raspberry Pi 4B running Fedora 38 (server edition) that I use
as a little occasional server for random things.  Since it doesn't
always have NTP available, I added an RTC module, and added
"dtoverlay=i2c-rtc,ds1307" to /boot/efi/config.txt (no other change);
all is good.

Now I have a short-term need to use it as a desktop, so I put the XFCE
spin on a different uSD card.  I made the same edit to config.txt... and
it doesn't work.  No RTC.

I've loaded all the Fedora updates, including the firmware with
"rpi-uboot-update", but it still doesn't work.  If I swap back to the
"server" uSD card, it sees the RTC.

The only difference I can see is that the original card is 32G and the
new card is 64G (so "SDXC")... would that be an issue to the firmware
