Hello Stefan,
these are another improvements for kwboot, please apply only after series
arm: mvebu: nandpagesize support for kwbimage v1
The main improvement is in patch 5, which changes where we inject the code
for changing baudrate

Could you try to upload some file in u-boot via xmodem at different
speeds? E.g. via loadx command:
loadx 921600
and
loadx 115200

Could you try to upload some file in u-boot via xmodem at different
speeds? E.g. via loadx command:
loadx 921600

loadx 115200
And compare if xmodem transfer is in

Perfect! So it really looks like that issue is in the code which resets

I have there another diff which removes usage of the stack in code which
resets baudrate back to default value:
diff --git a/tools/kwboot.c

The main improvement is in patch 5, which changes where we inject the code
