/// 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- #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;
- }
