1,修改 android/device/ init.sun7i.rc
增加:- ........(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)
复制代码 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
复制代码 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)
复制代码 4,开机,,效果,,运行了两个hello
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- #include<stdio.h>
- #include <signal.h>
- int main(void)
- {
- int i;
- signal(SIGCHLD, SIG_IGN);
- daemon(0, 0);//fork 强制后台运行!
- // for(i = 0; i < 10; i++)
- while(1)
- {
- sleep(1);
- printf("hello......by jiangdou\n");
- }
- return 0;
- }
