///  xinit  增加：  xinit    /usr/local/bin/xfreerdp  192.168.1.196

1,修改 android/device/    init.sun7i.rc

........(略)

#add by jiangdou
    chmod 777 /system/bin/hello
    chmod 777 /system/bin/dou.sh
service init-setup /system/bin/dou.sh
    class main
    user root
    group root
    oneshot

........(略)

2,在device/softwinner/sugar-cubieboard2/新建dou.sh  文件，内容：

#! /system/bin/sh

#hello是C编译的文件，是静态编译，，放在system/bin/
/system/bin/hello     

#or

hello

echo "jiangdou"

exit

3,vi device/softwinner/sugar-cubieboard2/sugar_cubieboard2.mk   ///目的是执行make -j48  复制到out/target/product/sugar-cubieboard2/system/bin/

........(略)

#add by jiangdou 
PRODUCT_COPY_FILES += \
        device/softwinner/sugar-cubieboard2/hello:system/bin/hello \
        device/softwinner/sugar-cubieboard2/dou.sh:system/bin/dou.sh

........(略)

4,开机，，效果

root@android:/ # ps | busybox grep hello
root      1409  1     652    108   c006bf0c 0001090c S /system/bin/hello
root      1411  1     652    108   c006bf0c 0001090c S hello
root@android:/ # 

证明开机自动运行了

5, C代码内容,,,,编译$  arm-linux-androideabi-gcc -o  hello hello.c  -static

1. #include<stdio.h>  
2. #include <signal.h>  
3. int main(void)  
4. {  
5.   
6.    int i;  
7.     signal(SIGCHLD, SIG_IGN);  
8.   
9.     daemon(0, 0);//fork 强制后台运行!    daemon祥见下面的文章
10.    // for(i = 0; i < 10; i++)  
11.    while(1)  
12.     {  
13.      sleep(1);  
14.      printf("hello......by jiangdou\n");  
15.     }  
16.  return 0;  
17. }
