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JDK1.6 SE(install JDK1.6 SE)

登陆http://www.myzr.com.cn的下载专区，下载jdk-6u45-linux-x64.bin文件
login in downloads of http://www.myzr.com.cn, to download jdk-6u45-linux-x64.bin
$ cd /usr
$ sudo mkdir java
$ cd java
$ sudo cp ~ /jdk-6u45-linux-x64.bin ./
$ sudo chmod 777 ./jdk-6u45-linux-x64.bin
$ sudo ./jdk-6u45-linux-x64.bin
$ sudo gedit /etc/profile
增加以下环境变量
add the following environment variables
export JAVA_HOME=/usr/java/jdk1.6.0_45
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

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=~/myandroid/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi- $ export PATH=~/myandroid/bootable/bootloader/uboot-imx/tools:$PATH

编译uboot(compile uboot)

$ cd ~/myandroid/bootable/bootloader/uboot-imx
$ make distclean
$ make mx6q_sabresd_android_config (四核配置)
$ make mx6q_sabresd_android_config (quadruple core configuration)
或 $ make mx6dl_sabresd_android_config (双核简化配置)
or $ make mx6dl_sabresd_android_config (dual core tile configuration)
