I have found TinkerBoars 2s can set a new MAC address sometime after update to a new Android image ( Android 11 v2.0.3).
I can burn Androin image for a few times on the same board and get some different MAC. And sometimes this addresses can become the same on different boards.
Having some boards at the same time in the same LAN with the same MAC - and this cause problems with network communication.
Is this normal for changing to random and non-unique MAC addresses after flashing?
Can we change this MAC after flashing, restore original MAC or be sure to keep the same MAC as it was before reburn?
