增加USB辨认

增加配置到config.txt

echo -e "enable_uart=1 \notg_mode=1" >> /boot/config.txt
也能够在Windows上，间接批改boot分区下的config.txt

装置ipk包

opkg updateopkg install usb-modeswitch kmod-mii kmod-usb-net kmod-usb-wdm kmod-usb-net-qmi-wwan uqmi

可选ipk包

ADD SUPPORT FOR MBIM DEVICES
kmod-usb-net-cdc-mbim Kernel module for MBIM Devices
umbim MBIM modem utility

opkg updateopkg install kmod-usb-net-cdc-mbim umbim

ADD SUPPORT FOR PC INTERFACE (TTYUSB0) - YOU NEED IT IF YOU WANT TO SEND AT COMMANDS, FOR EG. TO CHECK YOUR BALANCE BY USSD.

kmod-usb-serial-option
kmod-usb-serial
kmod-usb-serial-wwan

opkg updateopkg install kmod-usb-serial-option kmod-usb-serial kmod-usb-serial-wwan

查看设施是否存在

装置lsusb命令，可不装

opkg install usbutils

重启设施利用驱动程序

此时曾经能够查看到EC25

编译拨号软件

下载Quectel_QConnectManager_Linux软件拨号

Quectel_QConnectManager_Linux

因为扩大了零碎空间，抉择间接将此压缩包放在openwrt设施上解压

opkg update && opkg install unzip make gcc#解压压缩包unzip Quectel_QConnectManager_Linux_V1.6.0.16.zip

编译

在编译过程中发现缺失两个lib库 pthread,dl

抉择从工具链中间接复制两个库到设施

下载工具链并解压到linux零碎下

# 文件地位# pthread<YourPath>/openwrt-toolchain-22.03.2-bcm27xx-bcm2711_gcc-11.2.0_musl.Linux-x86_64/toolchain-aarch64_cortex-a72_gcc-11.2.0_musl/lib/libpthread.a# dl<YourPath>/openwrt-toolchain-22.03.2-bcm27xx-bcm2711_gcc-11.2.0_musl.Linux-x86_64/toolchain-aarch64_cortex-a72_gcc-11.2.0_musl/lib/libdl.a

将这两个文件放到openwrt零碎/usr/lib目录下，而后进入方才解压拨号软件的文件夹中，执行make命令

cd quectel-CMmake release

期待执行完结即可失去quectel-CM二进制文件，执行后即可拨号

./quectel-CM
