So far it works OK. I didn't do any special tests. Just set-up a WiFI accesspoint with hostapd (on bridge eth2/wlan0) and udhcpd. iptables for masquerading and just now accessing internet from my phone using
ifconfig shows three Ethernet interfaces. the two real ones are eth0 and eth2.
Let me know if I could be of any help. Would be a pleasure for me to give a bit back to Armbian :-)
Both, RockPi-E and OpiR1+ generate a Kernel panic at the end of "init 0" harmless AFAICS. Output is attached.
