当前是基于文章 [二、海思平台USB转网口在Win10上的使用 ][USB_Win10_]的基础上进行的。

一、开发板分配PC主机局域网下的IP地址[  ][USB_Win10_]

从图中,我们可以看到PC主机的局域网信息为

IP地址：172.19.0.2    
    网关：172.19.0.1

那么我们给开发板给分配一个IP地址，如： 172.19.0.250 执行命令如下：

ifconfig usb0 172.19.1.250 netmask 255.255.0.0;route add default gw 172.19.0.1

如下图

二、配置Windows10下网络参数

1、将USB转网口配置成,如下图

2、将本地网络跟USB虚拟网口 同时选中后 进行桥接

桥接成功之后，会出现如下图标

通过命令行查看

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhbjEyMDU3NjY2NA_size_16_color_FFFFFF_t_70 4][]

IP地址已经换成 172.19.121.140

三、开发板与外网通信

通过查询可以知道百度某个服务器的IP地址为  [14.215.178.61][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhbjEyMDU3NjY2NA_size_16_color_FFFFFF_t_70 5][]

在开发板上面执行

ping 14.215.178.61

结果如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhbjEyMDU3NjY2NA_size_16_color_FFFFFF_t_70 6][]

可以看到开发板已经可以访问外网了。

四、开发板与PC互PING

至此,开发板已经成功连接到局域网了
