HDLP-S500にシリアルをつなぐ

HDLP-S500をいじりたおしているうちに、ついに赤ランプ点滅、ブザーなりっぱなしで立ち上がらなくなってしまいました。。
このままではらちがあかないので何が原因でエラーなのかを探るべく、HDLP-S500にシリアルをつないでみました

実はパーティションサイズを変更してみようとboot時に自作のscript.shを実行させているのですが、こいつが悪さをしてHDLP-S500が立ち上がらなくなっているのでした
なのでシリアルをつないでエラーの原因を見ようと思ったわけです。

調査したところ、シリアルコネクタの割り当ては、以下の図のようになっていました。

シリアルの設定は図の中に記載してるとおり

115200 8bit stop 1 parity なし

でした。
なお、このコネクタへの入出力は +3.3Vなので、PCのシリアルに接続するには別途レベル変換が必要となります。
実際に取り付けてみました。

以下、boot時のシリアルのlogです。

ここまではうまく動いているようです
ですが、その後自作のscript.shを実行しようとして、、、(途中省略しています)

つまりスクリプトの実行パスにsmartctlがないために起動に失敗していることがわかりました。

boot時のエラーの原因を探るべくシリアルを接続してみました。
おかげでパーティションのきりなおしもうまくいって、現在は理想の形で復帰しています
この辺はまた別の機会にしようとおもいます。

いかがだったでしょうか
