AR9331な小さなオモチャにシリアルを生やす

先日紹介したAR9331な小さなオモチャ(zsun111)にシリアルを生やしました。
線を3本伸ばしただけです。
これでu-bootにアクセスし放題です。
シリアルのパターンは存在するものの、パターンサイズが小さいので細い線を用意してください。
あとは使い慣れたこてで頑張りましょう。
配列はこんな感じになっています。
写真上側から、GND、VCC、RX、TXになります。
面倒なのでVCCは付けずに3本にしています。VCCは無いからといって困らないので。
シリアル生やす作業自体は5分かからない簡単作業なので、みなさんもどうですか？
写真下側に存在するパターンは、Ethernetらしいのだが、RJ45ジャックを付けるのも面倒なので、シリアル転送でコーヒー飲みながら頑張るとしましょう。
u-bootのイメージを送るにはRJ45があった方が便利だが、パターンの小ささがすこし辛い。
とりあえずOpenWrtを起動してみますかねぇ。
恒例の純正ファームの起動ログは貼っておきます。
