错误: request_suspend_state: wakeup init: untracked pid 123 exited

原因：（1）检查发现这是由于init.rc里面会重新mount根文件系统为只读，导致init.rc不能创建子目录。

      （2）如果在ICS启动时，串口输出init: untracked pid之类的错误，说明init程序所在的分区权限不够，需要修改，在Telechips的代码中。

解决方法：需要修改init.rc,注释掉：mount yaffs2 mtd@system /system ro remount语句即可。

                    有这样一行：mount rootfs rootfs / ro remount。把它注释掉就可以了


 

同步Android代码时遇到错误：fatal: empty ident  <wyp@ubuntu.(none)> not allowed

是你没有正确设置电子邮箱和用户名

//看上边这句话，貌似说“告诉你是谁？”
//Run就是解决方法咯（这是系统提示的）
Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: empty ident  <wyp@ubuntu.(none)> not allowed
//具体做法如下
wyp@ubuntu:~/android_source$ git config --global user.email "renjiameng@yeah.net"
wyp@ubuntu:~/android_source$ git config --global user.name "rjm"
wyp@ubuntu:~/android_source$ repo init -u https://android.googlesource.com/platform/manifest

Your identity is: rjm <renjiameng@yeah.net>
If you want to change this, please re-run 'repo init' with --config-name
