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 loader? -- Chris Adams <linux@xxxxxxxxxxx> _______________________________________________ arm mailing list -- arm@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to arm-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/arm@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
