RK3576+kernel6.1+Android14移远5G模组(RG200U-CN Mini PCIe)调试

CV牛马工程师 2025-03-21 00:01:03
简介RK3576+kernel6.1+Android14移远5G模组(RG200U-CN Mini PCIe)调试

这篇文章主要是5G模组的配置过程，包括底层调试，一些较新的SDK许多4G、5G的相关配置和服务都没有添加，因此需要添加添加配置和增加5G服务，遇到的问题及解决处理方法

一，底层调试

原理图

dts

这个 5G 模组是 usb 接口，所以需要查看模块的 PID 和 VID ， lsusb查看是 2c7c:0900
再查看 drivers/usb/serial/option.c 这个文件是否包含此 ID 的枚举。发现是具备的，就不做修改，如果没有就需要添加
查看 dev 下的 ttyUSB* 枚举了几个，查看是枚举了 ttyUSB0~ttyUSB4 。仔细查看他们的权限都是 666 。这个需要在 rc 服务操作
文件路径： device/rockchip/common/rootdir/ueventd.rockchip.rc 操作 ttyUSB0~ttyUSB4 的权限
添加移远自己的驱动 
kernel-6.1drivers
etusb
+ qmi_wwan_q.c   
kernel-6.1drivers
etusbMakefile
+ obj-$(CONFIG_USB_NET_QMI_WWAN) += qmi_wwan_q.o

二、添加配置和增加5G服务

由于此 sdk 比较新，许多 4G 、 5G 的相关配置和服务都没有添加，所以第一步就是添加配置和服务。下面代码的修改大部分在 device 目录
路径 device ockchipcommondevice.mk
chip/common/device.mkockchip/common/device.mkrockchip/common/device.mkr
ockchip/common/device.mk
作用：引入 4g_modem.mk，让系统编译时包含 4G 模块相关的配置。
路径 device ockchipcommonBoardConfig.mk

作用：使能4G

路径 device ockchip k3576BoardConfig.mk

+#4g 
+BOARD_HAS_RK_4G_MODEM := true 
+BUILD_BROKEN_ELF_PREBUILT_PRODUCT_COPY_FILES := true  #此添加项是为了防止编译报错
