Depuis plusieurs années l'installation de Xenomai sur un Raspberry Pi 1 se fait assez facilement, et les résultats en sont plutôt satisfaisants. 前回は、Raspberry Pi 3(以下RPi3)にRT Preemptカーネルを導入しました。今回は Xenomai カーネルを導入してみます。Xenomaiもリアルタイムカーネルの一種ですが、よりリアルタイム性の高い性能が特徴です。通常はノーマルなカーネルと互換的に動作しますが、専用のライブラリ(API)類を利用すれば、よりリアルタイム性が高いアプリケーションを作ることもできます。, 組み込み向けなCNC機器やロボットの制御では、Xenomaiを採用している場合が多いようです(LinuxCNCが有名)。音楽系ではあまり使われていませんが、Beaglebone Black用の音楽系の開発環境BelaはXenomaiを採用しています。, 専用のライブラリを利用しないとXenomaiの良さを十分に引き出すことができないとも言えますが、Xenomai KernelをRPi3向けにビルドして、実際に試してみたいと思います。, Xenomaiの現行のバージョンには、2系列と3系列があります。3系列が最新ではありますが、2系列とは異なる部分も多いようで、安定性を求める場合は2系列を利用することが多いようです。3系列は、ノーマルカーネル4 系列に対応しており、RPi3で利用するにはそのほうが問題が少ないと思われるため、今回は、Xenomai3を試します。(Xenomai2系列はノーマルカーネル3系列までの対応のようです)また、Xenomai3は、2種類あります。, という切り分けです。今回はCobaltを利用します。Xenomaiはこの記事を書いている時点で最新安定版のバージョン3.0.2を利用します。ノーマルカーネルのバージョンは、4.1.21を利用します。, Xenomaiもノーマルのカーネルにパッチをあてる形式ですので、RT Preemptの場合と同様の方法でビルドします。Xenomaiはフレームワークでもあるので、カーネルに加えてライブラリ類のビルドも行います。, カーネル本体のビルドは、Linuxを使いクロスコンパイルしますのでLinux環境が必要です。仮想環境で構いません。私はWindowsでは、VirtualBoxを、Mac上ではParallelsを利用し、Debian系のディストリビューションを使っています。, Xenomaiを導入するRPi3用に、新規にSDカードにRaspbianを書き込み、ネットワークの設定も行い、, も実行しておきましょう。Raspbianは通常版でもLITE版でもどちらでも構いません。, ノーマルカーネルのソースをダウンロードします。ダウンロード時間の短縮のためターゲットバージョンのソースだけダウンロードします。, つぎにビルド用に環境変数をセットします。これらは、一時的な設定ですので再起動/再ログイン等で元に戻ります。作業中は再起動しないでください。, これで自動的に設定が書き込まれます。これ以外の項目を設定するため設定ツールをビルド&起動します。, ビルドが正常終了すれば、自動的にツールが起動します。ツール中で以下の項目を設定します。[ ]はチェック無し(チェックを外す)、[x]チェック有り(チェックを付ける)です。, CPU Power Management  ---->CPU Frequency scaling  ---->    [ ] CPU Frequency scaling, CPU idle  ---->        [ ] CPU idle PM support, Kernel Features  ---->    [ ] Contiguous Memory Allocator    [ ] Allow for memory compaction, Kernel Hacking  ---->    [ ] KGDB: kernel debugger, Boot options  ---->    Kernel command line type ---->        [x] Extend bootloader kernel arguments, 設定を変更したら[Save]を選択して保存します。各項目ごとに[Save]しておいたほうが安全です。[Save]画面では、ファイル名を変更せず、そのままOKを押します。設定が完了したら、いよいよカーネル類をビルドしましょう。, マルチコアCPUの場合は、-j2 などのオプションを付けるとビルドが早くなります。数字はコア数です。, raspberrypi.localは、RPi3のIPアドレスでも良いです。パスワードを聞かれるので、変えていなければraspberryと入力します。, ここで再起動すれば、Xenomaiカーネルで起動しますが、ユーザーホームに戻りライブラリ類を作成しますので、そのまま続行します。, 必要なライブラリやツール、デモツール等を作成します。参考にしたサイトではクロスコンパイル環境でLinuxでビルドしていましたが、RPi3上でビルドしたほうが簡単だと思います。, こちらでもXenomaiのパッチ類をダウンロードします。この中にライブラリ郡のソースも入っています。ダウンロードしたら展開します。, 作成したモジュール類のインストール時に、Wifiのモジュールが削除されています。システム的にはインストールされていることになっているので、一旦削除し再度インストールします。, Xenomaiは基本的にRootアカウントで動作する前提になっていますので、利用する場合はRootでログインしてしまったほうが簡単です。スタンドアロンで利用するのであれば大きな問題ないと思いますが、セキュリティ的な懸念がありますので、理解の上ご利用ください。, 起動時にユーザー名が聞かれるようになりますので、rootアカウトでログインします。, でテストが走れば、ライブラリ類の動作やインストール問題無いでしょう。 このツールはCtl+Cで停止します。, これでXenomai3のビルド&導入が完了しました。いくつか注意点があります。ノーマルのRaspbianは、CPU Governor の変更ができるようになっています(CPUのクロック数が可変ということ)が、Xenomaiではリアルタイム性に影響がでるため使えないようになっています。オーバークロックは試していませんが、おそらくはできると思います。, ディレクター、プロデューサー、ギタリスト。mimiCopyをはじめ弊社リリースの全てソフトウェア製品の企画を担当。ネイティブアプリ開発がメインでOS問わず対応可。dubバンドのギタリストとしても活動中。, artteknikaさんは、はてなブログを使っています。あなたもはてなブログをはじめてみませんか?, Powered by Hatena Blog Периодическая нить не работает в режиме реального времени в Xenomai (1) .

As described in previous post, most important work to obtain realtime EtherCAT Master on Raspberry pi is the realtime capable driver for Network controller, W5500 chip in this case.W5500 is controlled via SPI interface, writing driver for W5500 is mostly about working with SPI on Raspberry pi. Pull down and deploy. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.
