I.MX6 mkuserimg.sh 使用

/***********************************************************************
*                  I.MX6 mkuserimg.sh 使用
* 说明：
*     每次都要对Android源码进行模块化编译的时候，经常会遇到要重新制作
* system.img的问题，而普通的方式等待时间实在让人难以接受，而通过这个
* mkuserimg.sh来直接完成对system目录的打包正符合要求。

一、参考文档：
make_ext4fs制作system.img http://www.360doc.com/content/13/0419/13/12052771_279450163.shtml 
二、解读shell命令：
mkuserimg.sh out/target/product/sabresd_6dq/system out/target/product/sabresd_6dq/obj/PACKAGING/systemimage_intermediates/system.img ext4 system 293601280

三、步骤：
1. 293601280 / 1024 / 1024 = 280M
2. mkuserimg.sh out/target/product/sabresd_6dq/system out/target/product/sabresd_6dq/system.img ext4 system 293601280

四、reimg.sh
echo "begin to make system.img"
source build/envsetup.sh
lunch sabresd_6dq-eng
mkuserimg.sh out/target/product/sabresd_6dq/system out/target/product/sabresd_6dq/system.img ext4 system 293601280

五、运行现象：
myzr@myzr:~/myandroid$ ./reimg.sh
begin to make image
