安卓镜像构建指南

本文针对GDK8硬件介绍构建安卓镜像的基本步骤。
环境 Ubuntu18.04

安装工具

apt-get install python3 make gcc git gcc-aarch64-linux-gnu bison flex
ln -s /usr/bin/python3 /usr/bin/python
rm -rf .git*
git init
git config --global user.name "test"
git config --global user.email "test.com"
git commit --allow-empty -m "first commit"
git commit --allow-empty -m "first commit"

构建安卓内核

下载内核构建脚本:https://gedu.oss-cn-beijing.aliyuncs.com/build_kernel.sh

将build_kernel.sh放在kernel目录下
chmod +x build_kernel.sh
export CROSS_COMPILE=aarch64-linux-gnu-
./build_kernel.sh

报错:

gcc: error: unrecognized command line option '-mlittle-endian'; did you mean '-fconvert=little-endian'?

解决方案:

sudo apt-get install gcc-aarch64-linux-gnu
export CROSS_COMPILE=aarch64-linux-gnu-

打包镜像

由于安卓内没有dd命令,因此把kernel.img单独烧录到GDK8内,并不是太方便;因此采取打包完整镜像后,再进行烧录的策略。
下载GDK8镜像制作包:https://gedu.oss-cn-beijing.aliyuncs.com/gdk8_image_make.tar.gz

tar -xvf tar -xvf gdk8_image_make.tar.gz
cd gdk8_image_make
将内核中编译出来的*.img文件复制到gdk8_image_make/Image/目录下
./mkupdate_rk3328.sh
geduer@gdk:~/gdk8_image_make$ ls
afptool  Image  mkupdate_rk3328.sh  package-file-box  rkImageMaker
geduer@gdk:~/gdk8_image_make$ ./mkupdate_rk3328.sh
