安装ubuntu12.04

在这里建议用户使用64bit的ubuntu12.04的操作系统,已经真机编译验证过。

安装openjdk1.7

运行一下命令安装openjdk1.7
sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
sudo apt-get update
sudo apt-get install openjdk-7-jdk
$ sudo gedit /etc/profile
增加以下环境变量
export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$PATH:$JRE_HOME/bin
$ source /etc/profile
$ java –version
(看到版本为1.7.0_101就表示成功)

安装编译Android系统所需要的库

(详细信息,请看网站http://source.android.com/source/initializing.html)
$ sudo apt-get install git gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386
$ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so
$ sudo apt-get install uuid uuid-dev
$ sudo apt-get install zlib1g-dev liblz-dev
$ sudo apt-get install liblzo2-2 liblzo2-dev
$ sudo apt-get install lzop
$ sudo apt-get install git-core curl
$ sudo apt-get install u-boot-tools
$ sudo apt-get install mtd-utils
$ sudo apt-get install android-tools-fsutils

下载源码并解压源码

4.1下载源码

登陆http://www.myzr.com.cn下载专区下载Android5.1源码
Android5.1.1的分卷压缩解压后的源码包:myzr_android-5.1.1.tar.bz2

解压源码

$ mkdir ~/myandroid5.1
$ cd ~
$ tar -jxvf myzr_android-5.1.1_r1.tar.bz2

编译源码(Android系统)

设置环境变量

$ export ARCH=arm
$ export CROSS_COMPILE=~/myandroid5.1/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-
$ export PATH=~/myandroid5.1/bootable/bootloader/uboot-imx/tools:$PATH

编译uboot

$ cd ~/myandroid5.1/bootable/bootloader/uboot-imx
$ make distclean
$ make myimx6ek200-6q_android_defconfig (EK200-6Q-1G配置)
或 $ make myimx6ek200-6q-2g_android_defconfig (EK200-6Q-2G配置)
或 $ make myimx6ek200-6qp_android_defconfig (EK200-6QP-1G配置)
或 $ make myimx6ek200-6s-1g_android_defconfig (EK200-6S-1G配置)
或 $ make myimx6ek200-6u_android_defconfig (EK200-6U-1G配置)
或 $ make myimx6ek314-6q-2g_android_defconfig (EK314-6Q-2G配置)
或 $ make myimx6ek314-6q_android_defconfig (EK314-6Q-1G配置)
或 $ make myimx6ek314-6u_android_defconfig (EK314-6U-2G配置)
$ make

编译kernel

$ cd ~/myandroid5.1/kernel_imx
$ cp myzr.config .config
$ make uImage LOADADDR=0x10008000

编译bootimg (uImage和ramdisk)

$ cd ~/myandroid5.1
$ source build/envsetup.sh
$ lunch myimx6ek_6dq-user
$ make bootimage

编译system

$ cd ~/myandroid5.1
$ source build/envsetup.sh
$ lunch myimx6ek_6dq-user
$ make
结果如下图所示:

注意:生成的u-boot.imx在~/myandroid/bootable/bootloader/uboot-imx目录下,boot.img和recovery.img和system.img在~/myandroid/out/target/product/myimx6ek_6dq目录下。
