I think it would be good to know the exact HW revision of the used Pi5. It should the new D0 variant which uses a different device tree. So although 'Pi5', in combination with that RP1 it is quite possible some address mapping or so is wrong. There is a lot detailed info on https://www.raspberrypi.com/documentation/, what is missing is a brief architectural blocklevel overview. That would help pin-pointing the problem area.
