CON12 に電源を接続すると、Armadillo-IoT ゲートウェイ A6が起動します。
本章では、保守モードで起動したときの例を示します。 オートブートモードで起動した場合は、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、上記のような 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 10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 10 "buster") 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。
