[PATCH u-boot-marvell v3 00/39] kwboot higher baudrate

[Stefan Roese]

Hi Marek, Hi Pali,

since now all is merged into master, I'm testing on my AXP target
again. Please see below.

I'm not getting this when using master:

Changing baudrate to 230400 Bd
Baudrate was not changed


xmodem: Protocol error
