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-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。
