Yocto：Beagleboardが動作しない：フレームバッファーデバイスなし

Question

私はビーグルボードBB-MB-000 Rev. C4を持っており、レシピを使ってYoctoとuImage 4.4.9をmeta-ti-layerから構築していますlinux-ti-staging_4.4.bb。 mmcから起動できないため、私はBeandleboardをnandから起動しようとしました。しかし、それは今問題ではありません。

のxserverが起動することはできません行方不明FB0デバイスのため、次が見つからないためフレームバッファデバイス用のxinitの

yoctoとインターネットを検索私はもっと年配の人はいません。誰か助けてくれますか？

Answer 1

local.confにX11とウェイランドを削除します。

DISTRO_FEATURES_remove = "x11 wayland"

をあなたはまた、U-ブートuEnv.txtに "解放" しなければなりません。

Qt5を使用していますか？
