起動と終了

5.1. 起動

電源入力インターフェースに電源を接続すると Armadillo-IoT ゲートウェイ G4 が起動します。起動すると CON6 (USB コンソールインターフェース) から起動ログが表示されます。

[注記]

Armadillo-IoT ゲートウェイ G4 の電源投入時点でのジャンパ JP1 の状態によって起動モードが変化します。 詳しくは 「JP1(起動デバイス設定ジャンパ)」 を参照してください。

以下に起動ログの例を示します。

[重要項目]

Armadillo BaseOS ではルートファイルシステムに overlayfs を採用しており、そのままではシステムが OFF すると内容は消えてしまいます。そのため persist_file コマンドが用意されています。このコマンドを利用することでファイル単位で変更を反映することができます。パスワードを設定した後には以下のコマンドを実行してください。

[armadillo ~]# persist_file /etc/shadow

5.3. 終了方法

安全に終了させる場合は、次のようにコマンドを実行し、「reboot: Power down」と表示されたのを確認してから電源を切断します。

[armadillo ~]# poweroff

[警告]

haltコマンドで終了させた場合、「reboot: System halted」と表示されてから約128秒後、Armadilloは自動的に再起動します。確実に終了させるためにもpoweroffコマンドを利用してください。

[警告]

電源を再投入する際は、コンデンサに蓄えられた電荷を抜くため、電源を切断後、一定時間以上待つ必要があります。 開発セット付属のACアダプタの場合に必要な時間は以下のとおりです。

  • DCプラグ側で電源を切断した場合 : 約5秒
  • ACプラグ側で電源を切断した場合 : 約1分

コンデンサに蓄えられた電荷が抜ける前に電源を再投入した場合、 電源シーケンスが守られず、起動しない等の動作不具合の原因となります。
