IODATA WN-G300DGR OpenWrt #2

WN-G300DR が wr512-3gn の OpenWrt イメージで動いているとの情報をいただいた。
WN-G300DGR は，WN-G300DR のギガビット版。 WN-G300DGR #1
DGR では，tftp ブートでOpenWrt の起動は成功したが，LANが使用できない状況となった。以下がその経緯である。

シリアル接続では，tftp ブートの選択のみ可能で，ファームウェアのフラッシュ書き込みができない。
また，オリジナルの Web管理画面にあるファームウェア更新では「ファイルが正しくありません」でエラーとなった。

openwrt-ramips-rt305x-wr512-3gn-4M-initramfs-uImage.bin を ImageWN-G300DGR にリネームして，/tftpboot にコピーした。
つぎに，DGR にシリアルとLANで接続した。

minicom –s
/dev/ttyUSB0, 57600 8N1, no, no

すぐに1を押して，ｔｆｔｐブートを選んだ。
