It is what I don't know. controlfile only says "incorrect checksum in

Endianness perhaps? Per comment in ControlFileData:

Footprint switch should help show you why it is incompatible and also
protect you during development to break some structure.
Apparently the footprint switch didn't provide any insight into the
Sparc 32/64-bit issue, so I'm not too impressed..
