說明
由於需要用到全志的芯片的orangepi_zero的開源板子做項目，需要定制linux系統，對系統添加內置程序，修改鏡像大小和ubuntu系統版本。需要對源碼編譯生成ubuntu系統鏡像。
使用編譯環境
編譯內核使用的是docke容器，比較方便。封裝打包內核生成鏡像使用實體機ubuntu16.04 64位。因為打包鏡像在docker內運行會出錯。
docker地址
docker pull registry.cn-shenzhen.aliyuncs.com/qusir/orangepi_zero:0.2
源碼地址
https://github.com/QUSIR/orangepi_h2_linux
依賴項安裝
設置dtc編譯uboot
運行容器
docker run -it -v /home/orangepi_h2_linux:/data registry.cn-shenzhen.aliyuncs.com/qusir/orangepi_zero:0.2 bash
說明：將orangepi_h2_linux源碼目錄映射到容器的data文件夾
編譯dtc
dtc下載地址 鏈接：https://pan.baidu.com/s/1sndX30T 密碼：c2mw
7z x dtc.7z
cd dtc
make
設置dtc環境變量
export PATH=/data/dtc/:$PATH
設置交叉編譯器環境變量
export PATH="$PWD/brandy/gcc-linaro/bin":"$PATH"
編譯過程
編譯uboot
make CROSS_COMPILE=arm-linux-gnueabi- orangepi_zero_defconfig
編譯內核
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- sun8iw7p1smp_linux_defconfig
make -j8 ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage modules
編譯文件生成文件拷貝
cp -rf ./linux-3.4/output/lib/* ./build/lib
cp -rf ./linux-3.4/arch/arm/boot/uImage ./build/uImage
cp -rf ./u-boot-2016.7/u-boot-sunxi-with-spl.bin ./build/uboot
cp -rf ./build/lib/* ../OrangePi-BuildLinux/orange/lib/
cp -rf ./build/uImage ../OrangePi-BuildLinux/orange/
cp -rf ./build/uboot/u-boot-sunxi-with-spl.bin ../OrangePi-BuildLinux/orange/
cp -rf ./build/uboot/boot.scr ../OrangePi-BuildLinux/orange/
依賴項安裝
實體機上
apt-get install debootstrap qemu-user-static chroot
生成鏡像
./create_image
./image_from_dir linux-trusty orangepi ext4 zero
說明：linux-trust為執行create_imge所生成系統目錄，orangepi為生成鏡像名稱。
