Basisdaten
Hersteller ACME Systems
Typ Arietta G25
Zustand eingeschränkt nutzbar
Klassifizierung KlasseE-gruen.svg KlasseK-gruen.svg


Das Arietta G25 Board ist ein SoC ARM9@400MHz. Es ist aufgrund seiner Größe (25x53mm) und Preises von 20€ bzw. 30€ interessant.

Momentan ist das Lab selbst nicht im Besitz eines dieser Geräte. Einige Mitglieder z.B. Jürgen, Mose, Klaus und Schimmi besitzen eines, welches ggf. auf Anfrage genutzt werden könnte. Deshalb ist der Gerätestatus aktuell "eingeschränkt nutzbar".

SD-Card Image

Im Unterschied zum Board wie z.B. dem RaspberryPi gibt es für Arietta kein fertiges SD-Image, welches mit Programmen wie DD oder Win32DiskImager einfach auf die Karte geschrieben werden kann. Von ACME gibt es lediglich diese Anleitung, welche aber mit einem Windows System nicht durchführbar ist. Aus diesem Grund haben wir ein fertiges Image erstellt, welches einfach auf die SD-Karte geschrieben werden kann und anschließend bootfähig ist.

Debug Port Interface

Pinbelegung

Farbkodierung entsprechend FTDI-Standardbelegung

1 2 3 4 5 6
Vcc 3V3 EN5V (in) TxD (out) RxD (in) WKUP (in) GND

Einstellung Terminalemulator

Bootvorgang

Mit einem USB-Serial-TTL-Adapter kann man am Debug Port (DP) ein Terminal anschließen und den Bootvorgang beobachten. Nach erfolgreichem Bootvorgang dient der DP als Serielle Konsole /dev/ttyS0.

Fehler beim SD-Card-Zugriff

Bootversuch ohne/fehlerhafter microSD-Card bringt lediglich folgende Meldung

 RomBOOT

Bootversuch mit microSD-Card, aber fehlendem Kernel: (d.h. der Chip hat einen "minimal loader" im ROM)
