检查系统是否已经识别到设备

# lsusb ......Bus 001 Device 002: ID 2c7c:0125......

加载 EC20 模块驱动MYIMX6EK200、MYIMX6EK314、MYIMX6EK336 加载方式

# insmod ~/my-demo/MY_EC20_GobiNet_L31452_IMX6A9.koGobiNet: Quectel_WCDMA&LTE_linux&AndroID_GobiNet_Driver_V1.3.0GobiNet 1-1.5:1.4 eth2: register 'GobiNet' at usb-ci_hdrc.1-1.5, GobiNet Ethernet Device, 96:0d:4d:7d:fb:27creating qcqmi2usbcore: registered new interface driver GobiNet

MYIMX6EK14P 加载方式

# insmod ~/my-demo/MY_EC20_GobiNet_L31452_IMX6A7.koGobiNet: Quectel_WCDMA&LTE_linux&AndroID_GobiNet_Driver_V1.3.0GobiNet 1-1:1.4 eth2: register 'GobiNet' at usb-ci_hdrc.1-1, GobiNet Ethernet Device, 2a:19:b8:ca:f8:86creating qcqmi2usbcore: registered new interface driver GobiNet

执行 EC20 的拨号程序（后台运行）

关闭 EC20 的后台拨号程序

# pkill MY_EC20_Quectel*[01-23_13:15:17:527] requestDeactivateDefaultPDP err = 0[01-23_13:15:17:528] ifconfig eth2 down[01-23_13:15:17:791] GobiNetThread exit[01-23_13:15:17:794] main exit

从系统卸载 EC20 模块驱动

# rmmod GobiNet_EC20usbcore: deregistering interface driver GobiNetGobiNet 1-1:1.4 eth2: unregister 'GobiNet' usb-ci_hdrc.1-1, GobiNet Ethernet Device
