[MAC-Address of eth0 changes on every boot.]

Same problem with a NanoPi Neo and Buster 20.11.3.

 

An entry in /boot/armbianEnv.txt failed - but old school interface settings worked for me.

 

Bevor I tried nmcli commands.

 

[NanoPi NEO-LTS support]

I belive that Armbian will probably work on every version of  the NanoPi Neo line.

I am the ower of some NanoPi units - different hardware revsions -  is seems there was no problem with armbian

 

At the beginning the NanoPi suffered unter a heat cunduction problem - this was fixed with the next hardware revision.

 

A LTS version is for interesset for an industrial custumer- it is ensured that the outcome of a EMF tests, etc are untouched by a new hardware revision.
