概要

TinkerBoardで使えるOSイメージをビルド
(2017-3-21現在)
- ここでビルドしたものでは、WifiとBluetoothは使えない
- ASUSが、TinkerOSとか、カーネルのソースコード・ビルド手順を~~出してないよね?~~
  => https://github.com/TinkerBoard/debian_kernel ここにある。(2017-09-26更新... ずっと前から、みんな知ってるよな! 記事更新してなかった)
基本的に [TUTORIAL] Build a Tinker Board development image にそってます。
Windowsで、VirtualBox上に、Ubuntu16.04の仮想機を作って、そこでビルド。
作成したイメージは、sshが有効になっていて、ユーザ名: linaro / パスワード: linaroで、ログインできる。
3840x2160での表示(を縮小したもの)....

環境

ASUS TinkerBoard
仮想機ホスト: Windows 10 64bit
- Vagrant 1.9.2
- Virtualbox 5.0.32
- 仮想マシン: Ubuntu 16.04
  - ベースイメージ ubuntu/xenial64 (20170320.0.0) 使用
  - CPU:2コア / RAM: 4GB (お好みにより変更)
  - ソースコードとか生成物を置く、16GBの外部ディスクイメージを作成(/vagrant/disk-ext4.img, /vagrantは Windowsから提供される共有フォルダ)
    sudo mount -t ext4 -o loop /vagrant/disk-ext4.img /mnt/tinker
    にて、マウント。起動ごとにうまくマウントすること.

手順

Windowsでの作業

インストールして使えるようにしとく::
- Vagrant
- Virtualbox
- git for Windows

C:\Vagrant\TB-Dev フォルダを作成して、Vagrantfileを作る

Vagrantfile

# Vagrantfile
# mt08

VB_NAME="Build-TinkerOS-MoDoKi"
VM_MEMORY=4096
VM_CORES=2
VM_HOSTNAME="TB-MoDoKi.local"

Vagrant.configure("2") do |config|
	config.vm.box = "ubuntu/xenial64"
	config.ssh.username = 'ubuntu'

	config.vm.provider "virtualbox" do |vb|
		vb.gui    = false 
		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

		apt-get update
		apt-get upgrade -y
		
		apt-get install -y git build-essential bc libssl-dev
		apt-get install -y gcc-arm-linux-gnueabihf u-boot-tools device-tree-compiler mtools parted  binfmt-support
		apt-get install -y qemu-user-static
		apt-get install -y python-dbus python-debian python-parted python-yaml python-apt

		# python-support for Ubuntu 16.04
		wget http://launchpadlibrarian.net/109052632/python-support_1.0.15_all.deb
		dpkg -i ./python-support_1.0.15_all.deb
		rm -fv ./python-support_1.0.15_all.deb
		apt-get install -f
	SHELL
end

Git Bashをひらいて、
1. 仮想機起動:
  vagrant up
2. ... 返って来るまで、待つ ...
3. 16GBのファイル(disk-ext4.img)を作る
  fsutil file createnew disk-ext4.img 17179869184
4. sshログイン
  vagrant ssh

Ubuntuでの作業

ファイルの確認:
ls -l /vagrant/disk-ext4.img
ext4でフォーマット
mkfs.ext4 /vagrant/disk-ext4.img

マウントして、作業フォルダ作成・移動

sudo mkdir /mnt/tinker
sudo mount -t ext4 -o loop /vagrant/disk-ext4.img /mnt/tinker/
ls -l /mnt/tinker  #確認
cd /mnt/tinker     #移動
sudo mkdir tinkeroscustom
sudo chmod 777 tinkeroscustom
sudo chown ubuntu.ubuntu tinkeroscustom
cd tinkeroscustom

ソースコード・スクリプトなど取得

結構、時間かかるよ

cd /mnt/tinker/tinkeroscustom
git clone https://github.com/rockchip-linux/kernel.git
git clone https://github.com/rockchip-linux/u-boot.git
git clone https://github.com/rockchip-linux/rk-rootfs-build.git
git clone https://github.com/rockchip-linux/build.git

ビルド

uboot:
build/mk-uboot.sh miniarm

参考

real    0m32.818s
user    0m26.388s
sys     0m2.136s

rootfsイメージ作成

cd rk-rootfs-build/
# 必要なパッケージ導入
sudo dpkg -i ubuntu-build-service/packages/*
sudo apt-get install -f

# ビルド

カーネルビルド

cd /mnt/tinker/tinkeroscustom
build/mk-kernel.sh miniarm
	#参考time
	#real    8m38.834s
	#user    14m12.372s
	#sys     1m20.440s

仕上げ

rk3288の編集: vi build/extlinux/rk3288.conf
root=/dev/mmcblk2p7 を root=/dev/mmcblk0p7へ

こんな感じ/mnt/tinker/tinkeroscustombuild/extlinux/rk3288.conf

label kernel-4.4
	kernel /zImage
	fdt /rk3288-miniarm.dtb
	append  earlyprintk console=tty1 console=ttyS2,115200n8 rw root=/dev/mmcblk0p7 rootfstype=ext4 init=/sbin/init

sdイメージ作成

build/mk-image.sh -c miniarm -t boot
build/mk-image.sh -c miniarm -t system -s 4000 -r rk-rootfs-build/linaro-rootfs.img

out/system.img

system.imgをSDにやく

ubuntu@ubuntu-xenial:/mnt/tinker/tinkeroscustom$ ls -l ./out/system.img
-rw-rw-r-- 1 ubuntu ubuntu 1974607872 Mar 21 17:20 ./out/system.img

Windows側へコピー:
cp out/system.img /vagrant/
=> Windowsから、いつものツールで、SDに焼く
