Cubieboard2 unreachable after switch restart


Recommended Posts

Cubieboard2 becomes unreachable on ethernet if the switch to which the CB2 connected to is rebooted/powered off then on.

Every other devices communicate after the restart, except CB2, it needs an on/off to make its networking work again. Why?


It has fixed IP, and also set fixed mac address, but no luck. It runs the latest armbian (5.38), with mainline kernel

Only deep analysis can answer such question. I don't have Cubieboard2 to recreate this situation and haven't noticed such problem elsewhere. I can only check on some most similar board - Olimex Lime. But it will take some time.
