Arduino Uno Q 2GB - Try out
kenichiro90Arduino Uno Q 2GB を購入したので、色々と試していきます。
これ以降、試したことや調べたことなどを書いていきます。
kenichiro90まずは、USBシリアル変換ケーブルを使って、シリアルポート(UART)からの出力を見てみます。
kenichiro90出力結果は、以下のとおりです。
（長いので、Linux が起動し始めるあたりまでの内容を、貼り付けておきます）

CPUについては、特筆することはないですね。
パーティションの方ですが、bbcblk0には70個近くのパーティションが居るようです…
よくわからないので、オプションをつけて再度実行してみました。

70個近くあるパーティションのラベル名は、上記のとおりです。
パーティションの後ろ側に、Linuxのrootfsなどが置かれてました。
mmcblk0boot0, mmcblk0boot1 は何のためのものか分からないので、後で調べようと思います。
kenichiro90gpioがどうなっているのか気になるので、gpioinfoを実行してみました。

gpioは、2つのチップで処理しているようです。この辺りの情報は、データシートを見ればわかると思うので、後ほど確認してみようと思います。
kenichiro90今日は、PC Hosted Mode を試してみようと思います。
kenichiro90とりあえず、Arduino App Lab をインストールして、起動してみます。
kenichiro90起動するとこんな画面が出ます。
kenichiro90Arduino Uno Q を接続していると、ボードを選択できるようになるので、選択します。すると、Network Setup画面が出てきます。ここでWi-Fi接続の設定ができるので、設定していきます。
kenichiro90接続に成功すると、Examplesが表示されるようです。画面左下に、ターミナルのアイコンがあるので、クリックしてみます。
kenichiro90クリックしてみると、ターミナルが表示されました。
SSHではなく、adbで接続されてますね。
kenichiro90SSH周りの設定がどうなってるか、/etc/ssh/sshd_config を確認してみました。
X11Forwarding が yes になってるのは、VPN接続するためでしょうか…

SSH経由で接続できるか、試してみたところ、普通につながりました。
