初歩的な質問となってしまうのですが、armadillo-x2でUSB/CAN変換デバイスを使おうと考えています。
変換デバイス：https://www.peak-system.com/PCAN-USB.199.0.html?&L=1
このような場合、armadillo-x2またはATDEでどのような対応(ドライバのインストール手順)を取るのが良いのでしょうか？
よろしくお願いします。

> ドライバーをインストールした後に /dev/can0 が生成されるはずなので、コンテナのコンフィグレーションに 「add_devices /dev/can0 」を指定していただければ使用可能になります。
上記方法を試したのですが、/dev/can0が生成されない状況です。

参考までに、カーネルアップデートはリンク先の方法を参考にしています。

また、SWUアップデート自体はアルマジロの出力から成功していると思います。

マルティネです。

了解しました。
最初の返事はデバイスメーカーのサイトだけを参考にしていましたので、
もう少し確認します。
> また、SWUアップデート自体はアルマジロの出力から成功していると思います。
この出力とコンフィグの画像で問題ないと思いますが、いくつか確認させてください：
- インストールされたカーネルが /proc/config.gz に反映されますので、まずは有効にした設定があるかとモジュールの存在の確認です：
armadillo:~# zcat /proc/config.gz | grep CAN_PEAK_USB CONFIG_CAN_PEAK_USB=m armadillo:~# modinfo peak_usb filename: /lib/modules/5.10.../kernel/drivers/net/can/usb/peak_usb/peak_usb.ko author: Stephane Grosjean <s.grosjean@peak-system.com> description: CAN driver for PEAK-System USB adapters license: GPL v2 alias: usb:v0C72p0014d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0C72p0013d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0C72p0011d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0C72p0012d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0C72p000Dd*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0C72p000Cd*dc*dsc*dp*ic*isc*ip*in* ...
- そのドライバは「alias」でリストされている usb vendor/product id がある場合にロードされますので、USB/CAN変換デバイスが接続されている状態で lsusb を実行してデバイス ID を確認させてください (「ID 0C72:00○○」があるはずです）。
ある場合にモジュールもロードされるはずです：
armadillo:~# lsusb Bus 003 Device 001: ID 1d6b:0002 Bus 001 Device 001: ID 1d6b:0002 ... armadillo:~# lsmod Module Size Used by Not tainted
- モジュールがロードされている場合は 「dmesg」 の出力に何かのエラーが表示されている可能性が高いので、そのコマンドの出力も添付していただければ助かります。
よろしくお願いします。

モジュールが無事にロードされましたね。
私の勘違いでお手数をお掛けしましたが、最初から /dev/can0 というデバイスがなくていいらしいです。
（can を linux で使ったことなかったので勘違いしていました）
おそらく 「ip link」でネットワークインターフェースを表示すると can0 のインタフェースがあると思いますが、どうでしょうか？
コンテナで使う場合は add_devices ではなく、「
set_network host<code>」で使用可能になります。 「<code>add_args --cap-add NET_ADMIN
」も必要かもしれません。
https://elinux.org/Bringing_CAN_interface_up / https://developer.ridgerun.com/wiki/index.php/How_to_configure_and_use_… によりますと、can0 インターフェースの bitrate を設定する必要があります（iproute2 の ip コマンドが必要だと思いますので、このコマンドも iproute2 がインストールされているコンテナで実行してみてください）
# ip link set can0 type can bitrate 125000 # ip link set up can0
コンテナに can-utils パッケージをインストールしていただければ candump/cansend コマンド等で確認できます。
（コンテナがアルマジロのネットワークを直接に使うことになります。厳密には can インターフェスだけをコンテナに提供することもできますが、複雑な手順になりますのでひとまずこれで確認していただければと思います）
よろしくお願いします。

自分でドライバの導入することに自信がある場合を除いて、この製品ではなく
FTDIやProlific, silicon labs等のLinuxカーネルにデバイスドライバが含まれる
製品を使うことをお勧めします。

ちなみにlsusbコマンドを実行すると、
armadillo:/sys/bus/usb-serial/drivers# lsusb ... Bus 001 Device 005: ID 067b:23a3 Prolific Technology Inc. ATEN USB to Serial Bridge ...
と表示される場合は、Prolific、つまり新規のドライバインストール無しで使用することが出来るのでしょうか？

> 変換デバイス：https://www.peak-system.com/PCAN-USB.199.0.html?&L=1
> このような場合、armadillo-x2またはATDEでどのような対応(ドライバのインストール手順)を取るのが良いのでしょうか？
このデバイスの Linux ドライバーの案内はこちらですね：
https://www.peak-system.com/fileadmin/media/linux/index.htm
確認したところ、標準のドライバで問題ないですが、Armadillo X2 のデフォルト状態では有効にされてませんので、まずは ATDE で Linux カーネルをビルドする必要があります。
以下の手順でビルド・インストールしていただければ、「menuconfig」のステップに 「
/」キーで検索モードに入って、「CAN_PEAK_USB」 を入力して、「1」で選択して、「m」でモジュールとして有効にしてください。https://manual.atmark-techno.com/armadillo-iot-g4/armadillo-iotg-g4_pro…
ドライバーをインストールした後に /dev/can0 が生成されるはずなので、コンテナのコンフィグレーションに 「add_devices /dev/can0 」を指定していただければ使用可能になります。
（ATDE で vscode のサンプルプロジェクトを使う場合は config/app.conf ファイルを編集してください）
このドライバで問題なければ、次のアップデートで Armadillo の標準なカーネルで有効にしようと思いますので、問題の有無を確認していただければ助かります。
作業で何か分からないところがあればまた聞いてください。
よろしくお願いします。
