openwrt移植LTE模块

Openwrt移植LTE模块

1．  增加具体设备驱动

文档位置：/drivers/usb/serial/option.c 注意：是target开头目录下的文件

在文件中添加如下内容：

static conststruct usb_device_id option_ids[] = {  

{USB_DEVICE(0x19d2, 0x0536) },

...

}

0x19d2 和 0x0536 是模块设备的VID 和 PID

可以插入到linux系统上lsusb可以查看其VID和PID的值。

3．编译内核

驱动添加需要配置系统

Linux系统内核，配置方法如下：make menuconfig

这些可以多选，例如我就选了很多，可能我有的没有选全，根据需求自己选择需要的。

然后还需要进入内核编译配置：makekernel_menuconfig进入配置界面

然后设置ppp拨号的配置项：

注意上面选不出*号的话选M就行了

执行make V=s

编译成功截图：

如果想在源码中一键编译实现该功能，首先在源码dl目录下解压linux-3.10.14-p112871.tar.xz

然后重复上诉修改option.c，然后重新打包后，同时修改.config文件，这样就可以实现一键编译了。
