# Raspberry Pi 4でYocto Project入門 (2022/7/12) [Raspberry Pi 4とWSL2を使ってYocto Project入門 - Qiita](https://qiita.com/y-tsutsu/items/cbae3a2da083d42421c1) に従って試してみる。(Beelink-u59にて) ``` bitbake-layers add-layer ../meta-raspberrypi/ ``` まで実行。ツールが足らないとか言われてる。そうそう、ツール類をインストールするのを忘れていた。 ``` $ sudo apt install -y gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat cpio python python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping libsdl1.2-dev xterm ``` と言われるがままに実行。すでにインストールしているものはたくさんあるが、していないものもそこそこあるため。 今度は成功。 meta-raspberrypiが追加されたみたい。ここから先は明日にしよう。 (2022/7/13) 続きをやってみた。 ``` $ cd ~/yocto/poky $ git clone git://git.openembedded.org/meta-openembedded $ cd meta-openembedded $ git checkout -b gatesgarth origin/gatesgarth $ cd ~/yocto/poky/rpi-build $ bitbake-layers add-layer ../meta-openembedded/meta-oe/ $ bitbake-layers add-layer ../meta-openembedded/meta-python/ $ bitbake-layers add-layer ../meta-openembedded/meta-multimedia/ $ bitbake-layers add-layer ../meta-openembedded/meta-networking/ ``` で、conf/bblayers.confに、add-layerしたものが追加されていることを確認して、local.confに、 ``` MACHINE ?= "raspberrypi4-64" ``` と設定して、 ``` $ cd ~/yocto/poky/rpi-build $ bitbake core-image-base ``` を実行。(HDDの空き容量を確保した上で) ``` beelink-u59:~/yocto/poky/rpi-build$ bitbake core-image-base Loading cache: 100% |############################################################################################################################################################| Time: 0:00:00 Loaded 3330 entries from dependency cache.
