Hi, I tried to run the bullseye installer from
http://ftp2.de.debian.org/debian/dists/bullseye/main/installer-armhf/current/ images/netboot/SD-card-images/ on a cubox-i using a serial console today. It seems the network interface does not come up properly: ~ # dmesg |grep eth [ 5.009246] fec 2188000.ethernet: Invalid MAC address: 00:00:00:00:00:00 [ 5.015982] fec 2188000.ethernet: Using random MAC address: 4a: 0d:a7:66:c1:e6 [ 5.028381] mdio_bus 2188000.ethernet-1: MDIO device at address 0 is missing.

This was buster based, but had a recent kernel. This indicates that the issue is related with the kernel. The same network cable works on a buster x86 system and even with the cubox-i with a SD card with and older xbian version without any issues. Any hint or idea what could be wrong is apprectiated. If anybody has a way to get debug data (e.g. dmseg output) easier from the cubox than copy and paste from minicom, that would also help. Many thanks Rainer -- Rainer Dorsch http://bokomoko.de/
