On rp2350 CPUs, uf2 files created using elf2uf2-rs do not load correctly. Copying the file to the mounted RP2350 file system does not program flash and does not restart into application mode.

However a uf2 created from the same elf file using "picotool uf2 convert" works correctly.

RP2350 needs different family IDs depending on the CPU architecture.
that means RP2350 is not supported yet.
