We have a custom design based on STMP32MP133A na an spi NAND. On paper, using the u-boot diagnostic commands, everything is working correctly.

I tried also download only the multivolume file and it ends abruptly with this error:

It looks like it's working, but after writing 1.7MB it crashes.

The USB download gadget is always available while the procedure is running, I can't see any problem or disconnection.

Any Idea?
