Yocto Linux で tmp/deploy/images/ 以下を再生成する

Background

build/tmp/deploy/images 以下にはカーネルやユーザランドのイメージファイルが生成される。ディスク掃除の一環でそれらを消したあとに runqemu すると以下のようなエラーが出る。

$ runqemu
runqemu - INFO - Running bitbake -e  ...
ls: cannot access '/home/tomoki/poky/build/tmp/deploy/images/qemux86-64/*.qemuboot.conf': No such file or directory
runqemu - ERROR - Command 'ls -t /home/tomoki/poky/build/tmp/deploy/images/qemux86-64/*.qemuboot.conf' returned non-zero exit status 2.
runqemu - INFO - Cleaning up
runqemu - INFO - Host uptime: 449.42

$ runqemu
runqemu - INFO - Running bitbake -e  ...
runqemu - ERROR - KERNEL not found: /home/tomoki/poky/build/tmp/deploy/images/qemux86-64/${@bb.utils.contains("INITRAMFS_IMAGE_BUNDLE", "1", "bzImage-${INITRAMFS_LINK_NAME}.bin", "bzImage", d)}, /home/tomoki/poky/build/tmp/deploy/images/qemux86-64/bzImage or /home/tomoki/poky/build/tmp/deploy/images/qemux86-64/bzImage*
runqemu - INFO - Cleaning up
runqemu - INFO - Host uptime: 155.84

このとき bitbake をしても再生成がされなくて困る。

$ bitbake core-image-sato

対処方法

clean してからもう一度 bitbake すれば大丈夫。ビルドは走らない。

$ bitbake linux-yocto -c clean
$ bitbake core-image-sato -c clean
$ bitbake core-image-sato

ちなみに clean は以下のように説明されている。

$ bitbake linux-yocto -c listtasks
...
do_clean                              Removes all output files for a target
do_cleanall                           Removes all output files, shared state cache, and downloaded source files for a target
