In the serial console I see:

   U-Boot 2022.04 (Jul 01 2022 - 06:22:22 +0000)

   DRAM:  1.9 GiB
   RPI 4 Model B (0xb03115)
   Core:  196 devices, 13 uclasses, devicetree: board
   MMC:   mmc@7e300000: 3, emmc2@7e340000: 0
   Loading Environment from FAT... In:    serial
   ...

This was just, when stating 14.0-CURRENT. In the serial console I can scroll back, while on a HDMI screen this would rush away too quickly, but perhaps you would be able to take a photo, for finding out your model's revision.

In 13.1-STABLE the RTC issue was fixed as well. If I can't built a custom kernel on 13.1-RELEASE then I will stay with 14.0-CURRENT, even if I would have preferred RELEASE, but a working RTC is more important for me.

OK, here I just found out the build of a 14.0-CURRENT custom kernel does execute without any failure.

I forgot to mention, that I tried to get the 13.1-RELEASE custom kernels to work by installing the most recent u-boot.bin from the ports. This didn't help either.
