硬件原理与准备1.1 硬件拓扑SoC:RK3568OS:Android14Kernel:Linux6.14G 模块:Quectel EM060K (M.2 接口走 USB 3.0/2.0 协议)双卡方案:SIM1 连接到模拟开关通道 ASIM2 连接到模拟开关通道 B模拟开关输出连接到 EM06K 的 SIM 接口1.2 准备工作RK3568 Android 14 源码环境移远官方提供的驱动包Quectel_Linux_USB_Serial_Option_DriverQuectel_Android_RIL_Driver (注意获取适配 Android 14 的版本)二、内核驱动移植 (Kernel)在 Android 14 (Kernel 6.1) 中首先要确保 EM06K 被识别。2.1 添加 USB VID/PID修改 drivers/usb/serial/option.c在 usb_device_id 列表中添加 EM06K 的 ID通常移远模块 VID 为 0x030b/* Quectel EM06K */#defineQUECTEL_PRODUCT_EM060K0x030b{USB_DEVICE_AND_INTERFACE_INFO(QUECTEL_VENDOR_ID,QUECTEL_PRODUCT_EM060K,0xff,0x00,0x40)},{USB_DEVICE_AND_INTERFACE_INFO(QUECTEL_VENDOR_ID,QUECTEL_PRODUCT_EM060K,0xff,0xff,0x30)},{USB_DEVICE_AND_INTERFACE_INFO(QUECTEL_VENDOR_ID,QUECTEL_PRODUCT_EM060K,0xff,0xff,0x40)},2.2 驱动移植参考移远文档推荐使用qmi_wwan_q.c将文件放到放到kernel-6.1/drivers/net/usb。文档说可以和内核自带的qmi_wwan.c可以共存但编译起来还是有点差异我就把qmi_wwan.c注释掉了不影响正常使用kernel-6.1/drivers/net/usb/Makefile配置如下#obj-$(CONFIG_USB_NET_QMI_WWAN)qmi_wwan.oobj-$(CONFIG_USB_NET_QMI_WWAN)qmi_wwan_q.o和配置rockchip_deconfigCONFIG_USB_NET_QMI_WWANy移植完成后查看日志[568.184715][T86]usb1-1:Product:EM060K-GL[568.184755][T86]usb1-1:Manufacturer:Quectel[568.184792][T86]usb1-1:SerialNumber:5b050a26[568.338560][T86]option1-1:1.0:GSMmodem(1-port)converter

Driver版本需要大于V4.0.0。3.1 移植 RIL 库在 Android 的 RIL (Radio Interface Layer) 架构中libril.so 和 libreference-ril.so 是两个处于不同层级、承担不同职责的关键动态链接库。libril.so 对接上层它负责与 rild (RIL Daemon 守护进程) 配合接收来自 Android Framework (电话服务进程) 的请求在 Android 8.0 以后通过 HIDL/AIDL 接口早期通过 Socket而 libreference-ril.so 是模组厂商参考 Google 标准写的“硬件操作员”负责对接 4G/5G 模块比如将标准请求翻译成该模组能听懂的 AT 指令如 ATD10086;并通过串口/dev/ttyUSB2 等发送给 4G 模块。这是移远提供的ril库但短信功能不能使用我会将ril相关库放到附件。然后将ril相关文件到系统源码将libril.so以及libreference-ril.so 放到vendor/rockchip/common/phone/lib下将chat、ip-down、ip-up 放到vendor/rockchip/common/phone/bin下将ql-ril.conf放到vendor/rockchip/common/phone/codec下3.2 修改系统配置修改device/rockchip/rk356x/BoardConfig.mkdiff--git a/device/rockchip/rk356x/BoardConfig.mk

默认不知道你有两张物理卡我们需要通过给em060k模块发指令来“欺骗”模块让它重新读卡。6.1 切换流程查询卡槽防止不知切哪个卡槽指令ATQUIMSLOT?切卡指令QUIMSLOT: 1。重置模块通过 CFUN0/1 或者复位引脚让 EM06K 重新初始化并读取新的 SIM 卡信息。这一步移远自动处理系统点击重启即可6.2
