2gbsd-noeclipse-sep062011.dd - SDへ書き込み Windowsでは、DD for Windows(シリコンリナックス株式会社)を使用しました。 http://www.si-linux.co.jp/techinfo/index.php?DD%20for%20Windows
SDから起動
- Jumper::Bootをショート(SD起動)
- MicroSDをセットする
- Serial-USBケーブルで、TS-7553のCOMポートに接続、Terminal起動(TeraTermとか) 115200bps, 8 data bits, 1 stop bit
- USBポート(USB Bコネクタ・でかいやつ)から電源供給
- SW1を押し続ける。
- TS-7533上のGreenLEDが消えて、RedLEDが点灯したら、SW1を離す。

- xnandimg(NANDイメージ)をダウンロード ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7500-linux/binaries/ts-images/xnandimg-sep062011.dd.bz2
- 解凍 =>
xnandimg-sep062011.dd(256MBのサイズ) - 適当なMicroSDをFAT(32)フォーマットして、ファイルをコピー。
- TS-7553をSDから起動して、プロンプトが出たら、xnandimgの入ったMicroSDを差し替える。
- 以下のようにタイプして、NANDへ書き込む。
blocksize=131072から 15分くらいで、書き込み完了
