Atmel NGW100 SD-Card Compatibility

Das Atmel NGW100 ist ein Router/Network-Gateway als Entwicklungsplattform. Das NGW100 hat auch einen SD/MMC-Card-Slot und kann auch von einer SD-Karte starten. Aber es gibt gelegentlich Probleme mit verschiedenen SD- oder MMC-Cards.

Oft liegt es an einer alten Version des im internen Flash abgelegten Bootloaders U-Boot, wenn neuere bzw. grössere SD-Karten verwendet werden. In diesem kurzen Test wurde ein NGW100 im Lieferzustand (2010) getestet. Die Version des Loaders ist "U-Boot 1.1.4-at0 (Jan 3 2007 - 10:30:09)".

Alle getesteten Karten hatten eine Partition 1 mit maximal 200 MB Größe. Diese wurde mittels "mke2fs -I 128" formatiert, um eventuell vorhandene Kompatibilitätsprobleme mit grösseren Inodes zu vermeiden. Nach dem Einschalten des NGW100 wurden die Karten in der Shell von U-Boot mit den folgenden Befehlen "getestet":

mmcinit
ext2ls mmc 0:1
