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。
