AM335x - カスタムボードSystemdを実行するとき

TIフォーラムに質問をしてみましたが、フィードバックがあまりないので、ここで幸運を試してみようかと思いました。

ここで私がTIと進行中の議論を見ることができます。https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1158936/am3359-caught-segv-when-distro-s-systemd-starting

私たちはしばらくTI AM335x-ICEV2ボードを使用して組み込みLinuxアプリケーションを開発し、独自のカスタムボードデザインを受けました。多くのデバッグと読み込み後にU-Bootを正しくロードすることができました。 /または実行中断が発生します。

当初、私たちはDDR3マッピングのハードウェア問題を疑っていましたが、デザインはTIのすべての要件を尊重しているようです。さらに、ディスクの起動中は常に凍結/セグブが発生します。 U-BootまたはLinuxカーネルの起動中に単一の競合/停止/segvを見たことはありません。

私が始めることができる唯一の成功した構成は、SysVinitを使用してモジュールをまったくロードしないTI-Linux-SDKの小さなファイルシステムです。これまで、すべてのsystemd OS（DebianとArago）が失敗しました。既存のDebian 10イメージでSystemdをSysVに置き換えようとしましたが、失敗しました。

同じUboot +カーネルはTI IceV2開発で完全に実行されますが。板。

私はLinuxブートローダ/カーネルの専門家から遠く離れています。誰もがいくつかの質問に答えたいと思っている場合は、いくつかのデータを喜んで共有します。

起動時のコンソール出力は次のとおりです。

以下のアップデートを更新するために、文字数制限のためにこのコンテンツを削除しました。

これは私のFDTファイルです。

この問題はTIフォーラムで解決されており、興味のある方は以下のリンクをたどることができます。

全体的に問題は、私のVDD_MPU（1.1V）が私のPMICによって駆動され、PMICドライバが正しく初期化されていないことです。システムが CPU 周波数を上げる場合を意味します。 800MHzでは、1.1Vが低すぎるため、MPUの電源が切れ、破損します。解決策は、手動でVDD_MPUをより高い値（1.3V未満）に上げるか、CPU周波数に応じて電圧を自動的に管理するようにPMICを設定することでした。
