2. The '=> mmc partconf 0 0 0 0' command needs to be issued after the

last dfu command, not before like you did in this patch.

Read above.

I wonder why it works here and fails for you. Are you booting from USB or eMMC when running the DFU? What version are you using?

The mmc partconf order does make a difference here though.

I could only flash it when I ran it after the dfu command.

This is a mystery to me; here we did update it several times without it failing.

Please try:

mmc partconf 0 0 0 0 reset

after boot just program it and see if it helps.
