Fonera 2202のときに作成したシリアルケーブル(Vcc pull up)にてCQW-MRBへのシリアルコンソールの接続はできたようです。
ただし、コンソールログインが有効となっていないらしく、linuxの起動後は、Enterキーに対して、echo backの改行となるだけです。
コンソールからのログインプロンプトを出すには、CQW-MRBのファームウェアを展開して、手を入れなければならないのでしょうか。
分解の手順は、以下の通りです。
- バッテリー収納部の蓋をスライドさせて外す。バッテリを外す。
- バッテリー収納部の周辺の小ねじx4を外す。
- 筐体の裏カバーを外します。
あるピン配置に対して、9600, 19200, 34800, 57600, 115200と試して行く途中で、JP2のプリントパターンをいれて検索してみることを思いつき、「CQW-MRB JP2」 で検索したところ、twitterにすでに発見されている方の記録がありました。
http://twitter.com/lapis_moon/status/22545742065
確認の手間が大分省けました。感謝です。
JP2横のpinは 3.3V出ています。Vccではないかと思われます。
Pin配置については、下図を参照してください。
Fonera 2202とは違い Vcc は接続しなくともシリアルケーブルによるコンソール接続は機能するようです。
CQW-MRBの電源ONの直後にコンソールから何かキー入力があると、Ubootのプロンプトが表示されます。

初期状態ではキー入力の待ち時間を示す環境変数bootdelayが 1 となっています。これを 3 に変更します。

環境変数 bootdelayの値を 3 (秒)として、保存・再起動します。
