Das kann man auch aus verschiedenen Richtungen sehen, wäre es nicht möglich das die Board erst für das Unternehmen produziert wurden welches dann aber pleite ging weil es sich nicht gerechnet hat? Das Board ansich ist leistungsstark genug um damit einige Sachen zu machen und perfekt für so diy Leute wie uns 🙂

Software
Das System was ich hier teste ist ein Ubuntu mit LXDE Oberfläche.

Auf Debian Buster 10 sieht das dann so aus.

Damit weiß ich jetzt, das WiFi klappt, aber der Networkmanager
Ok, das bekomme ich auch noch irgendwie hin. -
Ok, manche Dinge MUSS man einfach lösen
So, der Networkmanager kaspert immer rum und will die WiFi-Verbindung nicht starten.

Lösung
Umsetzung
nano /etc/default/grubIn die Zeile GRUB_CMDLINE_LINUX_DEFAULT folgendes ergänzen
GRUB_CMDLINE_LINUX_DEFAULT="net.ifnames=0 console=ttyS0,115200n8"Das net.ifnames=0 verhindert das die Interfaces die neuen langen Bezeichnungen bekommen. Einige Treiber scheinen das nicht zu mögen, so auch der Treiber auf diesem AtomicPi Board.
Danach noch kurz den Bootloader aktualisieren.
sudo update-grubNeustarten. Problem gelöst!
