You'll need to follow the general section for HAT support (it's basically any HW that needs an overlay) and reboot and it should work: https://fedoraproject.org/w/index.php?title=Architectures/ARM/Raspberry_Pi/H...
That RTC is supported by the rtc-ds1307 driver.
I missed the link at the end of the config.txt that was Fedora specific. Maybe you could put that Fedora specific comment at the start of config.txt in a future release?
I have followed the steps and the RTC is working. I would like to add a section on the RTC to the docs. If that is useful how do I go about doing that?
But I have lost the HDMI console. I can ssh into the system and it is otherwise working.
I see the boot sequence, u-boot, grub, last message on screen is the Fedoara kernel line announcing its version. After a few seconds where I would expect to see systemd messages instead the monitor goes into standby.
Do I need to change setting in config.txt to make the HDMI work?
Here is my config.txt:
$ cat /boot/efi/config.txt | grep -v -e '^#' -e '^$' [pi4] dtoverlay=upstream-pi4 arm_boost=1 dtoverlay=vc4-kms-v3d-pi4 dtoverlay=cma,cma-256 max_framebuffers=2 dtoverlay=i2c-rtc,ds3231 [cm4] otg_mode=1 [all] arm_64bit=1 kernel=rpi-u-boot.bin dtoverlay=upstream enable_uart=1 bootcode_delay=1 gpu_mem=32 start_x=1 camera_auto_detect=1 display_auto_detect=1 hdmi_ignore_cec_init=1
