RK3568 开发板 安卓系统之4G模块驱动调试（十四）-rk3588 开发板

4.11 在RK3568开发板上调试4G(EC20)驱动

4.11.1 查看 RK3568 关于4G模块的原理图，获取需要配置的信息

4.11.2 需要配置的信息如下

1 4G模块电源使能引脚GPIO4_C3

2 4G模块W_DISABLE1引脚GPIO4_B5

3 4G模块复位引脚GPIO4_B4

4.11.3 DTS配置如下

{ rk_modem: rk-modem { compatible=”4g-modem-platdata”; pinctrl-names = “default”; pinctrl-0 = <&lte_vbat &lte_reset &lte_pwr>; 4G,vbat-gpios = <&gpio4 RK_PC3 GPIO_ACTIVE_HIGH>; 4G,power-gpios = <&gpio4 RK_PB5 GPIO_ACTIVE_LOW>; 4G,reset-gpios = <&gpio4 RK_PB4 GPIO_ACTIVE_HIGH>; status = “okay”; }; };

4.11.4 内核驱动增加对EC20的支持

由于改动较多，步骤不详细叙说，具体参数移远提供的移植文档《Quectel_LTE&5G_Linux_USB_Driver_User_Guide_V2.0.pdf》，说得很详细。

修改驱动

4.11.5 关闭selinux，打开4G模块支持

4.11.18 编译固件后，烧写固件验证

在启动的时候，可以看到串口打印有以下信息，说明正常识别到EC20的PID和VID了

开机会，等一段时间后，可以看到在状态栏上有4G图标了，执行以下操作

通过以上信息，可以看到，已经可以正常联网了。

4.11.19 调试过程中碰到的问题，能正常上网，但没图标

问题是在device/rockchip/rk356x/overlay/frameworks/base/core/res/res/values/config.xml添加信息不全造成的。

注意：以下这一行不加会导致能正常上网，但在状态栏无移动数据的图标
