Yoctoでビルドしたイメージのありかと書き込み方
題名の内容、メモして書き残します。
ビルドの方法とかはここに記載。
Yoctoでビルドした成果物は、最初にoe-init-build-envで指定したビルドディレクトリ（今回は rpi_build ディレクトリを指定しているのでそこ）以下に生成されます。
一応YoctoのManualを見ると、ちゃんと在り処まで記載されているのですがこのManualは膨大過ぎて見るのが嫌になります・・・
bitbakeの実行結果ですが、2019/6月時点でrpi-basic-imageをビルドするとこんな感じでした。
SATAのSSDに仮想マシンのファイルを立てて、Ryzen7 2700のフルコア/8GB RAMを割り当ててこの時間でした。ただし回線速度が結構遅いのでそれが問題かもしれません。

※横幅がブログ幅に入り切ってませんが大した情報ではないです
さておき、rpi-basic-imageのイメージはビルドディレクトリ/tmp/deploy/以下に格納されてます。
当該ディレクトリをそのまま載せると下記の通りめっちゃファイルがあります。

見ると、デバイスツリーやらU-Boot、Kernel Image（zImage）とかやらが散在しているのがわかります。
rpi-basic-imageはcore-image-minimalをベースにしているので、sdカード用の書き込みイメージが用意されます。

これです。
あとはddコマンドでSDに書き込めばOKです。自分はVMWareでここまで作業していますが、カードリーダーにSDを刺すとUbuntu側で認識するかどうか聞かれて、普通に/dev/sdbとして出てきたので楽でした。
sudo dd if=rpi-basic-image-raspberrypi-20190608085409.rootfs.rpi-sdimg of=/dev/sdb status=progress
※lsblkコマンド等で書き込み先（of=）のデバイス・ファイル名は確認すること
あとはRaspiにSDを差し込み、電源を入れればBootするハズです。
起動しない場合はSDの書き込み失敗や、容量不足を疑う。また諸々カスタムしていて起動しない場合は、UART接続を試みて何か出るか（Kernel Panic等）をCheckする。
Kernelまで行ってない場合は、rpi本体のROMコードを見てUARTで何を拾っているか確認したいところ・・・
