=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。<br>

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

=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<br>
Android5.1.1的分卷压缩解压后的源码包：myzr_android-5.1.1.tar.bz2<br>

==解压源码==
$ mkdir ~/myandroid5.1<br>
$ cd ~<br>
$ tar -jxvf myzr_android-5.1.1_r1.tar.bz2<br>

==编译源码（Android系统）==
===设置环境变量===
$ export ARCH=arm<br>
$ export CROSS_COMPILE=~/myandroid5.1/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-<br>
$ export PATH=~/myandroid5.1/bootable/bootloader/uboot-imx/tools:$PATH<br>

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

===编译kernel===
$ cd ~/myandroid5.1/kernel_imx<br>
$ cp myzr.config .config<br>
$ make uImage LOADADDR=0x10008000<br>

===编译bootimg (uImage和ramdisk)===
$ cd ~/myandroid5.1<br>
$ source build/envsetup.sh<br>
$ lunch myimx6ek_6dq-user <br>
$ make bootimage<br>

===编译system===
$ cd ~/myandroid5.1<br>
$ source build/envsetup.sh<br>
$ lunch myimx6ek_6dq-user <br>
$ make<br>
结果如下图所示：<br>
[[文件:MY_I.MX6_DEMO_Android5.1.1_2.png]]<br>
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。<br>
