article 2025/1/5 13:35:04

前言

平台：RK3568
系统：Android 11
需求：MEIG-SLM3XXX 4G模块适配

Kernel驱动配置

rockchip_defconfig需要配置ppp驱动与usb串口驱动

+ CONFIG_USB_SERIAL_GENERIC=y
+ CONFIG_USB_SERIAL_OPTION=y
+ CONFIG_USB_SERIAL_QT2=y

添加HID配置

对于Android8.0及以上版本，需要配置HIDL。

一般device下都有个宏DEVICE_MANIFEST_FILE配置了对应的manifest.xml文件，需要在此文件中配置radio相关的hidl，telephony service才能找到rild service,否则RIL跑不起来。

device/khadas/kvim/BoardConfig.mk:183:
DEVICE_MANIFEST_FILE:= device/khadas/common/products/mbox/manifest/manifest_aosp.xml 
+ <interface> 
+ <name>IRadio</name> 
+ <instance>slot1</instance> 
+ </interface> 
+ </hal>

+ </hal> 
+ <hal format="hidl"> 
<name>android.hardware.bluetooth</name> 
<transport>hwbinder</transport> 
<version>1.0</version>

添加网络属性相关配置

在网络属性中添加移动网络支持，在frameworks/base/core/res/res/values/config.xml配置，一般在对应device下overlay掉这个配置，需要注意以overlay下的config.xml为准。

添加RIL配置
1. 将附件的RIL适配.rar解压Android源码根目录下vendor/meig目录下
2. mk中添加美格ril配置，注意区分32跟64位，如我的平台是rk3568 64bit
