RK3588 Android12 广和通L716 4G模块调试记录
调试前先找模块厂获取相关资料
Kernel修改：
可用RK的参考配置来控制，把原理图对应角位配置上就行。
rk_modem: rk-modem {
compatible="4g-modem-platdata";
pinctrl-names = "default";
pinctrl-0 = <<e_vbat <e_power_en <e_reset>;
4G,vbat-gpio = <&gpio4 RK_PD0 GPIO_ACTIVE_HIGH>;
4G,power-gpio = <&gpio4 RK_PC6 GPIO_ACTIVE_LOW>;
4G,reset-gpio = <&gpio4 RK_PD4 GPIO_ACTIVE_LOW>;
status = "okay";
};添加模块VID,PID

如未生成对应节点先排查供电是否正常。
在排查主控对应USB phy节点是否打开
模块需保证 VBUS 信号连接到 5V 供电，若此信号悬空，USB 口无法正常枚举

输入AT指令到对应端口号查看是否检测到SIM卡
开两个adb端口，一个执行echo,一个执行cat
echo -e "AT+CPIN?" > /dev/ttyUSB2
cat /dev/ttyUSB2
CPIN: READY
查看信号强度：
echo -e "AT+CSQ\r\n" >/dev/ttyUSB2
cat /dev/ttyUSB2
+CSQ: 14,999.3 ifconfig -a查看网卡是否启动，如未启动，手动执行ifoconfig usb0 up，或者进入设置--网络选项
9.4 ping网络测试
如有问题请确认ril库是否对应模块及Android版本，系统是否已经加载上了ril库
adb logcat –b radio –v time 分析日志，结合AT指令排查，或将log发给模块厂帮忙看看。
