我准备在Linux主板命令行启动后网络SSH 下用shell脚本进行命令行功能测试 控制部分硬件测试。从IO控制-灯闪开始。
板手册中LED例:
**应开发板上的 RUN 灯 为例进行LED灯测试
root@myd-yr3562:~# cd /sys/class/leds
root@myd-yr3562:/sys/class/leds# echo 0 > run/brightness
root@myd-yr3562:/sys/class/leds# echo heartbeat > run/trigger
在板上使用shell脚本语言简单明了开发效率高便于调试修改动态性强资源利用灵活但实时性不足。
shell脚本是linux中壳层与命令行界面用户可以在shell脚本输入命令来执行各种各样的任务。可根据提供程序快速实现功能。
连接12V的电源 开发板上的eth0网线到路由```

进行IO控制其实不需要上显示和这么大的系统
实时性也不十分好。
转接网线/无线登录为root 用户，密码
在/etc目录下建立led.sh内容如下
#!/bin/sh
echo 0 > /sys/class/leds/user/brightness
while true; do
echo 1 > /sys/class/leds/run/brightness
sleep 2
echo heartbeat > /sys/class/leds/run/trigger
sleep 2
echo 0 > /sys/class/leds/run/brightness
echo 1 > /sys/class/leds/user/brightness
sleep 2
echo heartbeat > /sys/class/leds/user/trigger
sleep 2
echo 0 > /sys/class/leds/user/brightness
done
加x权限
root@myd-yr3562:/etc# chmod u+x
root@myd-yr3562:/etc# chmod u+x
执行shell脚本
root@myd-yr3562:/etc# sh ./led.sh
LED r g 灯正常 ****
设置下次开机启动，修改文件/etc/init.d/S99autorun.sh
#!/bin/sh
echo "user startup xxx.sh"
ifconfig eth1 down
/etc/myir_test/wifi_on_sta -ssid mali？？na12 -passwd 194？？？18
sh /etc/led.sh
