【yocto】特定のタスクでbitbakeを停止する方法

はじめに

• do_patch等でbitbakeを停止したい人向け
• 特定のタスクでbitbakeを止め、tmpディレクトリ以下(主にはtmp/work)を解析することで、どのタスクで問題が発生しているか等を解析できたりする。

方法

• cオプションを指定して、停止したいタスク(do_xxx)を指定する

bitbake -c do_xxx recipe-name

例

• ビルド準備

takeshi@X250:~/yocto/poky$ source oe-init-build-env 
(略)

• ビルド

takeshi@X250:~/yocto/poky/build$ bitbake -c do_patch core-image-minimal
(略)

• do_patchまででビルドが終わっているかを確認(★参照)
