[メモ] RaspberryPi向けyoctoのビルド (Vagrant,VirtualBox使用)

Last updated at 2017-03-30Posted at 2017-03-28

概要

Building Raspberry Pi Systems with Yoctoにしたがって、console-image をビルドするとこまで。
ビルドは通ったっぽいが、らずぱいでの動作は、まだ確認していない...確認できたら、記事を更新する予定。
関連: @Nao1215さん - Raspberry Pi3 with Yocto Project：環境構築

環境

ホスト: Windows 10 64bit
- Vagrant
- Virtualbox
- Git for Windows
ゲスト仮想機:
- ubuntu/xenial64
- 120GBのディスクサイズに拡張してる(けど、80GBくらいでもだいじょうぶかも?)
Raspberry Pi 2/3実機

手順

Vagrant, Virualbox, git for windowsを使えるようにする
Vagrantのdisksizeプラグインを導入:
vagrant plugin install vagrant-disksize

Vagrantfile

Vagrantfile

# Vagrantfile
# mt08

#VB_NAME="build-VM"
VM_MEMORY=8192
VM_CORES=2
#VM_HOSTNAME="build-yocto_poky-morty.local"

Vagrant.configure("2") do |config|
	config.vm.box = "ubuntu/xenial64"
	#config.vm.network "public_network", bridge: 'Intel(R) Ethernet Connection I217-LM'
	config.ssh.username = 'ubuntu'
	config.disksize.size = '120GB'

	config.vm.provider "virtualbox" do |vb|
		vb.gui = true
		#vb.name = VB_NAME
		vb.memory = VM_MEMORY
		vb.cpus = VM_CORES
	end

	config.vm.provision "shell", inline: <<-SHELL
		#echo 'Acquire::http::Proxy "http://apt-cache-server:3142";' | tee /etc/apt/apt.conf.d/02proxy

		export DEBIAN_FRONTEND=noninteractive

		apt-get update
		apt-get -y upgrade

		apt-get -y install build-essential chrpath diffstat gawk git libncurses5-dev pkg-config subversion texi2html texinfo
		apt-get -y install bc python2.7
		ln -sf /usr/bin/python2.7 /usr/bin/python
		dpkg-reconfigure dash
	SHELL

	config.vm.provision "shell", privileged: false, inline: <<-SHELL
		cd ${HOME}
		git clone -b morty git://git.yoctoproject.org/poky.git poky-morty
		cd poky-morty
		git clone -b morty git://git.openembedded.org/meta-openembedded
		git clone -b morty https://github.com/meta-qt5/meta-qt5.git
		git clone -b morty git://git.yoctoproject.org/meta-raspberrypi

		cd ${HOME}
		mkdir rpi
		cd rpi
		git clone -b morty git://github.com/jumpnow/meta-rpi

		cd ${HOME}
		mkdir -p ${HOME}/rpi/build/conf
		source poky-morty/oe-init-build-env ${HOME}/rpi/build

		cd $HOME/rpi
		cp meta-rpi/conf/local.conf.sample build/conf/local.conf
		cp meta-rpi/conf/bblayers.conf.sample build/conf/bblayers.conf
	SHELL
end

仮想機起動、再起動、sshログイン:
vagrant up && vagrant reload && vagrant ssh
...待つ...
仮想機sshログイン
1. 設定編集 bblayers.conf(編集する必要ないと思う):
  vi $HOME/rpi/build/conf/bblayers.conf
2. 設定編集 local.conf:
  vi $HOME/rpi/build/conf/local.conf
  1. MACHINE : raspberrypi2(RPi2/3向け) or raspberrypi (1/Zero向け)
  2. DL_DIR : 指定しないと、$HOME/rpi/build/downloads
  3. SSTATE_DIR: 指定しないと、$HOME/rpi/build/sstate-cache
  4. TMPDIR: 指定しないと、$HOME/rpi/build/tmp
3. ビルド開始
  ビルド

cd $HOME
source poky-morty/oe-init-build-env ~/rpi/build

time bitbake -c fetchall console-image # ファイルの取得のみ行う

time bitbake console-image

    4. 待つ
    5. `$HOME/rpi/build/tmp/deploy`中に成果物ができるはず。

## その他
- VM_CORESとVM_MEMORYはバランスよく。CPU増やしてもメモリが足りないと、落ちたり不安定になったりする。並列にビルド走るけど、ディスクアクセスも頻繁におこるようにもなるし、むずかしいね。
- ビルド後: `/dev/sda1       117G   46G   72G  39% /`

- (追記2017-0330)メモ : 2cores/8GBRAMで、fetchに137分、ビルドに309分
