So here are the final comments on this:

1. Disable entire serial console, as documented here [1]

   echo 'hw.fdt.console=3D"NO"' >> /boot/loader.conf.local

BTW the man page of loader.conf or loader must sy about this =
undocumented=20
variable setting.=20


2. Set a lower speed of the serial console from 115200 to 9600 for =
example

uboot config.txt
init_uart_baud=3D9600


It would be nice whoever wrote this part to properly document these such =
way this is not
a mission impossible to find. I will test in coming days these things to =
see if they actually=20
work.=20

Thanks Ian for tips and support
