如果是一个ARM-Linux的开发者,不难很快分析出来的Android的分区。
关于分区,可以看一下如下文章:
<>

一.检测Android 手机各种信息
首先安装HTC的USB 驱动。
基本上用Android SDK自带的命令行工具adb 就可以分析各个分区了.
运行如下命令进入Android精减的shell : toolbox
adb shell
下面是直接执行相应命令,这个应当是LINUX开发者比较熟悉一些指令了。
查看Nand flash的分区(即一般人称为ROM)的分区,这是我的HTC G8的分区
adb shell cat /proc/mtd
- E:\huisen\android\sdk\tools>adb shell cat /proc/mtd
