Hi Thomas,

it was a great work, I am currently trying to use but unfortunately,
I didn't managed to run barebox on the Armada XP OpenBlocks AX3 from
Plathome :/

I get something like that:

kwboot -t -b barebix.bin.kw -B 115200 /dev/ttyUSB0
Sending boot message. Please reboot the target...-

[here I power up the AX3]

Sending boot image...

I also found typo in the command line example you gave to use kwbimage.

I will try the other platform soon.

I think it should be:
./scripts/kwbimage -c -i <path/to/kwbimage.cfg> -o <image>

Thanks!
