Hello,

 

I tried Armbian_21.02.1_Orangepi4_bionic_current_5.10.12_minimal.img and Armbian_21.02.1_Orangepi4_buster_current_5.10.12.img

 

but these two version the eth0 doesn't work. This is the ifconfig printout

Tried using nmtui to activate but it does not activate and return

Same after upgrading my opi4

well you got a mac adress so hardware is seen

 

did you do a apt update /apt upgrade

 

seems more a systemd fault
