u-boot is the preferred option, and I just tried it on my Ci20, but it
seems the u-boot on this board doesn't find the network, so I can't
DHCP/TFTP (log below[1]).

If I just let the kernel boot that is flashed on the board, it boots up
an OpenWRT image and is able to DHCP and get an IP address, so I know
the network interface is working.

Maybe Ezequiel has a newer version of u-boot with working network
support I could try?  If so, please also send instructions for how to
(re)flash u-boot, (or maybe boot a new u-boot from the SD card?)
