Hello Mark,
thanks for getting back to me.
your diff works. I can connect to serial console
using speed 1500000. However when I use the
high speed the system does not boot. In order
to make system to boot I need to use the
OpenBSD preferred speed (115200). I've managed
to save the console when connected using high
speed so you should be able to see what's go wrong.

thanks for sharing the info. I think I'm going to stick to
booting using micro-SD.
your diff works as expected, it looks good to me, though
not sure my OK counts here. you may want to delete
the extra white space before committing it.

^^^^^
extra space here. otherwise looks as fare as I can tell.

Thanks and regards

This is the console when connected using the highs speed.
I can read everything, but nano-pc does not boot. The boot
process just freezes, I can not get to any command prompt
(uboot, nor boot loader).
