Software

Bez. Software: Mein Board wurde mit einem vorinstallierten Raspbian (wohl in Deutschland präpariert) auf SD-Karte geliefert. Der Anschluss einer Konsole ist sehr einfach, denn im Gegensatz zum RPi gibt es hier einen Debug-Port, an den man leicht einen Seriell/USB-Konverter anschließen kann. Der komplette Boot-Log ist am Ende des Artikels einsehbar.

Laut BPi GitBook sollen auch Images für Android und Ubuntu verfügbar sein. Beim mir allerdings hagelte es „404 – page not found“. Das wird sich hoffentlich bis zum Erscheinen des Boards noch ändern. Für den Typ M2 Ultra gibt es ein spezielles Linux, Tina-IoT von Allwinner, doch leider wird nicht erläutert, wie man das für M2 Berry anpassen könnte. Vielleicht läuft es direkt ohne Änderung – vielleicht aber auch nicht.

Der SD-Kartenslot des BPi (links)
ist breiter als beim RPi (rechts)

Fazit

BPi-M2 Berry zielt auf Leute, die sonst einen RPi einsetzen. Die Einführung nach dem Rollout des RPi3 sollte eigentlich erwarten lassen, dass BPi Berry mit der gleichen Leistung wie ein RPi3 aufwarten kann, doch leider liegt er nur auf dem Niveau von RPi2 v1.0 mit WLAN, Bluetooth 4.0 und SATA. Da BPi Berry aber preislich mit RPi3 vergleichbar ist, durfte allein sein SATA-Interface für BPi und gegen RPi (3 oder 2) sprechen.

Mein BPi-M2 Berry passte nicht recht in mein RPi-Test-Gehäuse, weil der SD-Kartenslot zu breit ist. Aber es handelt sich auch um ein Board der Vorserie, weshalb diese Inkompatibilität bei der Serie noch ausgebügelt werden könnte. Doch selbst wenn nicht hilft ein Teppichmesser und es passt. Problematischer sind da schon die inkompatiblen Anschlüsse für LCD und Kamera. Hier wurde auf Kompatibilität mit der BPi-Serie geachtet, aber ob die resultierende Inkompatibilität zu RPi das wirklich wert ist?

Boot-Log des Banana Pi M2 Berry

Linux-Experts finden in einem Boot-Log allerhand interessante Informationen. Also prangt es hier in voller Länge. Einloggen geschieht mit dem User „pi“ oder „root“; das Default-Passwort ist „bananapi“.
