RK3588 Android12 广和通L716 4G模块调试记录

移动开发 2023-09-18 22:51:03 阅读次数: 0

调试前先找模块厂获取相关资料

Kernel修改：

  1. 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 = <&lte_vbat &lte_power_en &lte_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";
};

  1. 添加模块VID,PID

  1. 内核编译配置项

平台已默认打开配置，按如下配置在检查下

CONFIG_PPP=y
CONFIG_PPP_MULTILINK=y
CONFIG_PPP_FILTER=y
CONFIG_PPP_ASYNC=y
CONFIG_PPP_SYNC_TTY=y
CONFIG_PPP_DEFLATE=y
CONFIG_PPP_BSDCOMP=y

  1. 将模块注册成usb0网卡

  1. 以上修改完成后编译烧录进机器查看是否生成对应设备

  1. 问题排查：

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

Android修改：

1.启动ril进程

2.打开系统4G服务

3.打开BOARD_HAS_RK_4G_MODEM选项后会有一些报错，添加如下补丁：（如打开宏没有报错不用添加下面补丁，rk3568可以直接编译，目前发现rk3588 android12会报错）

4.添加模块厂提供ril库编译并指定ril库路径

所需文件：libreference-ril-l716.so

ght_ril_config.ini

将文件拷贝到/device/rockchip/common/lib64目录

8.系统界面显示

FAQ：如有问题按如下方式排查：

9.编译完成后查看系统属性是否已经设置成功

[ro.ril.ecclist]: [112,911]

root         19667  2210 3 10:43:59 ttyFIQ0 00:00:00 grep rild

9.2AT指令排查

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: 14,99

9.3 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。
