電源入力インターフェース (Armadillo-610 拡張ボード: CON12) に電源を接続すると、Armadillo-610が起動します。
本章では、保守モードに設定しているときの例を示します。 オートブートモードを選択した場合は、途中でコマンドを入力することなく起動が完了します。
初めて起動した時は、 U-Boot の環境変数が eMMC に書き込まれていないために、次のように Warning が表示されます。
env save すると、次の起動から表示されなくなります。 詳しくは 9章ブートローダー (U-Boot) 仕様 を参照してください。
Linux システム (Debian 9 "Stretch") を起動するには、次のように boot コマンドを実行してください。コマンドを実行するとブートローダーが Linux システムを起動させます。シリアル通信ソフトウェアには Linux の起動ログが表示されます。
