私は組み込みボード用のカスタムLinux OSを構築するためのノブです。私の無知を無視してください。NanoPiネオボードでのカスタムLinuxビルド
カスタムDebian Linuxを搭載したNanoPi NEOというボードがあります。これで、ボードには.imgファイルが付属しています。これはSDカードにフラッシュしてスロットに差し込むことができ、ボードはカードから起動します。
私は自分のカスタムLinuxとフラッシュをSDカードに構築しようとしています。私はフォーラムやマニュアルを読んで、これまでのところこれを達成しました。
問題
私は、次の3つのコンポーネントが
- BOOT0カスタムビルドでlinuxにあることを理解 - 多くのブートローダの一つ - ブートローダ
- U-ブートをロードする事を。 （プロジェクトはこれを使用します）。
- Rootfs - ファイルシステムとそれ以外のすべて。
ボード製造元のWebサイトには、カスタムOSの構築手順が記載されています。these私はその指示に従って、SDカードの適切なパーティション分割（boot0用の空き領域、uImageとScript.binを持つブートパーティション、rootfs用のパーティション）を含むすべてを行った。
問題は、ボードがカーネル起動時にはファイルシステムをマウントせず、ユーザープロンプトを表示しません。
これはDmesg出力です。

最後に、「VFS：デバイス179：2上のマウントされたルート（ext4ファイルシステム）」です。問題はありません。もし「No working init found」パニック検出されなかったか、またはマウントされなかった。 – Notlikethat
それでは、systemdを起動させない原因は何ですか？いくつかのカーネルビルド設定が誤って設定されていますか？ – azmath
おそらく、もし最近のシステムであれば、3.4カーネルでは使えないかもしれませんが（https://cgit.freedesktop.org/systemd/systemd/tree/README#n38） 'init =/bin/sh'（または同等のもの）で起動しようとしましたか？それがOKになったら、おそらくsystemdの問題です。 – Notlikethat
