2、编辑/etc/wpa_supplicant.conf文件
root@rk3588-buildroot:/# cat /etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
update_config=1
network={
ssid="HONOR70"
psk="13572468"
key_mgmt=WPA-PSK
}
root@rk3588-buildroot:/#
3、【只需执行一次，下次重启就会自动连接了】
然后杀掉已经存在进程
killall wpa_supplicant
重新启动 wpa_supplicant 连接热点
wpa_supplicant -iwlan0 -Dnl80211 -c /etc/wpa_supplicant.conf -B
获取IP地址
udhcpc -i wlan0
连接成功
ifconfig wlan0
【可选：直接使用ifconfig】
【但是你不执行这些操作，直接重启，就会内核跑飞的！可以这个命令执行了一些操作/写配置文件！^_】
20250823给荣品RD-RK3588开发板刷Rockchip原厂的Buildroot【linux-5.10】时调通AP6275P的WIFI【源码部分】

【我是先将这个DTSI文件中的代码块直接搬到rk3588-evb7-lp4.dtsi中，然后就可以上网了。接着就微调到最终版本！】
