My board connected a USB WIFI, I don't want to log in to enter root at console.
1) Auto Login
Edit file:
/lib/systemd/system/serial-getty@.service
[Service]
Environment=TERM=vt100
ExecStart=-/sbin/agetty -a root -s %I 115200
2) Start Service
Create file:
/lib/systemd/system/robot.service
[Unit]
Description=Robot
After=syslog.target network.target network-online.target
[Service]
Type=simple
ExecStart=/usr/bin/run.sh
[Install]
WantedBy=multi-user.target
3) Script file
Create file:
/usr/bin/run.sh
#!/bin/sh
cd /home/root
./run_service.sh
4) Service file
/home/root/run_service.sh
#!/bin/sh
cd /sang/driver
insmod rfkill.ko
insmod cfg80211.ko

5) run /etc/profile after reboot

6) Start WIFI script file

killall wpa_supplicant
ip link set wlan0 up
iw dev wlan0 set power_save off
wpa_supplicant -B -D wext -i wlan0 -c /etc/wpa_supplicant.conf
