MYZR-I.MX6-DEMO Android5.1.1环境搭建

安装ubuntu12.04(install ubuntu12.04)

(如果使用下载明远智睿的虚拟机，请直接跳到 下载源码并解压 这一节)
（if virtual machine downloaded from MYZR is going to be used,please skip to the section"download source code and decompress"
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。
here it is recommended to users to use operating system of 64bit ubuntu12.04 of which has been proven in compilation by real machine

安装openjdk1.7(install openjdk1.7)

运行一下命令安装openjdk1.7
execute command to install 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
add the following environment variables
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）
(when version 1.6.0_45 is seen,which represent a success)

安装编译Android系统所需要的库(install libraries needed to compile Android system)

编译源码（Android系统）(compile source code(Android system))

设置环境变量(set environment variables)

$ 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(compile uboot)

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

编译kernel(compile kernetl)

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

编译bootimg (uImage和ramdisk)(compile bootimg (uImage and ramdisk))

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

编译system(compile system)

$ cd ~/myandroid5.1
$ source build/envsetup.sh
$ lunch myimx6ek_6dq-user
$ make
结果如下图所示：
results as the following figures showed

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。
note:u-boot.imx generated is in the directory of ~/myandroid/bootable/bootloader/uboot-imx，boot.img and recovery.img and system.img are in the directory of ~/myandroid/out/target/product/myimx6ek_6dq
