DM368+MT7601U通过wifi可以正常出图

       经过一段时间的研究，学习、baidu，我的DM368的主板终于可以通过WIFI传视频图像了。现在来记录一下的过程；

       一、USB驱动的正常识别；

              1) 、将USBWIFI模块插到DM368的硬件接口时，发现没有任何反应；

              2）、确认硬件接口：usb的工作模式：device模式 or host模式

                   

            3) 、确认硬件后，还是没有信息输出；只能修改内核代码：

                

                在串口中进行下面的确认：说明USB接口及驱动没有问题；

               

可以在 demsg | grep usb命令下看到下列结果：

二、在网下下载相关MT7601U的wifi模块的代码，编译USB-WIFI驱动‘

      

   http://www.mediatek.com/en/downloads1/downloads/

     其它的方法，可以参考网上的其它文档；

     值的注意的是，wirelessTools的版本，最好自己编译；否刚可能会出现下面的情况：

  

 

三、记录一下加载的过程：
