正运动技术 - Linux上电自启动程序说明

打开linux控制器中/etc/rc.local文件，将第一行#!/bin/sh -e修改为#!/bin/sh，在最后一行exit 0前添加要执行的语句。

注：若执行的程序需要依赖zmotion.lib库，则需加5s延迟

例子：VPLC516E控制器需开机执行/home/zmotion/test程序，修改/etc/rc.local后内容如下所示

#!/bin/sh

#

# rc.local

#

# This script is executed at the end of each multiuser runlevel.

# Make sure that the script will "exit 0" on success or any other

# value on error.

#

# In order to enable or disable this script just change the execution

# bits.

#

# By default this script does nothing.

chmod 777 /dev/ttyS*

dev="/dev/ttyUSB3"

if [ -c "$dev" ];then

sleep 3s

pppd call quectel-ppp &

else

echo "no exit ttyUSB"

fi



df | grep "4515168" | grep "root"

if [ $? -eq 0 ];then
