チュートリアル: Raspberry Pi 3 B+ 参照イメージを使用した Device Update for Azure IoT HubのRaspberry Pi OSイメージを作成してみて、どんな手順なのかを体験しようと思います。

手順はこちらです。

作業環境はWSLのUbuntu 20.04を使います。

作業ディレクトリを用意して、環境変数proj_rootに設定しておきます。

mkdir adu-os-image
cd adu-os-image
proj_root=`pwd`

Clone the Yocto projectを実行。

cd $project_root/yoctoは間違い。正しくはcd $proj_root/yocto。

yocto_release=honister
adu_release=main
git clone https://github.com/Azure/iot-hub-device-update-yocto -b main $proj_root
cd $proj_root/yocto
git clone --depth 1 --branch $yocto_release git://git.yoctoproject.org/poky

meta layer 6個をClone。

git clone --depth 1 --branch $yocto_release  https://github.com/sbabic/meta-swupdate
git clone --depth 1 --branch $yocto_release  git://git.openembedded.org/meta-openembedded
git clone --depth 1 --branch $yocto_release git://git.yoctoproject.org/meta-raspberrypi
git clone --branch $adu_release http://github.com/azure/meta-azure-device-update
git clone --branch $adu_release http://github.com/azure/meta-iot-hub-device-update-delta
git clone --branch $adu_release http://github.com/azure/meta-raspberrypi-adu

Install Build Dependencies and Toolsを実行する前に、ディレクトリがマズいので移動しておきます。

cd $proj_root

Install Build Dependencies and Toolsを実行。

sudo ./scripts/install-deps.hは間違い。正しくはsudo ./scripts/install-deps.sh。

sudo ./scripts/install-deps.sh
cd yocto/poky
git fetch
git checkout -t origin/honister -b my-honister
git pull
source oe-init-build-env

Build The Projectを実行する前に、ディレクトリがマズいので移動しておきます。

cd $proj_root

Build The Projectを実行。
引数の意味が分からないので、とりあえず掲載されているものをそのままで実行してみます。

yocto_release=honister
adu_release=honister

build_type=debug
build_number=1.0.1
build_output_dir=~/adu-yocto-build-output
./scripts/build.sh -c -t $build_type -v $build_number --adu-src-uri $adu_src_uri --adu-git-branch $adu_git_branch --adu-git-commit $adu_git_commit --do-src-uri $do_src_uri --do-git-branch $do_git_branch  --do-git-commit $do_git_commit --adu-delta-src-uri $adu_delta_src_uri --adu-delta-git-branch $adu_delta_git_branch --adu-delta-git-commit $adu_delta_git_commit -o $build_output_dir

9:36に開始して13:46に完了。約4時間かかりました。

Surface Book 3 (Quad-core 10th Gen Intel Core i7, RAM 32GiB, 1TiB PCIe SSD)

Azure Virtual Machineで試したところ、約1時間でした。

Standard D16ds v5 (vCPU 16, RAM 64GiB, OS Disk 256GiB)

まとめ

手順に軽微な間違いがいくつかあったが、雰囲気で乗り切れた。あとで手順訂正のPR出そう。
消費ディスク量は約67GiB。
所要時間は約5時間。長かった...。今度はAzure VM使おう。
