I updated an old 8 GiByte RPI4B's EEPROM and tested the microsd card
that was made earlier via an unmodified expansion (and dd) of

FreeBSD-14.3-STABLE-arm64-aarch64-RPI-20250724-f0a7a1bda375-272016.img.xz

and it booted the old 8 GiByte RPi4B from the microsd card just fine:

I do not have any access to 2 GiByte or less RPi4B's. Nor
to more modern 4 GiByte RPi4B's, just old v1.1's.

I do also have access to:

) 1 old RPi3B (so: both 64-bit and 32-bit capable)
) 1 old RPi2B v1.1 (so: 32-bit only)
) 1 old RPi2B v1.2 (so: also 64-bit capable)

(That last is basically a minor variation of the
RPi3B.)
