1.使用wifi实现上网 100ask_v853-pro全功能底板上板载有全志xr829，烧录的开发板系统已经进行了适配，可以直接使用，在开发板上输入ifconfig，可以显示已经使能的网络设备。

检查安装完成后，在开发板的串口终端输入wifi -s

接下来可以进行连接wifi进行上网，输入wifi -c ssid [passwd]，其中ssid为wifi名，passwd为密码
假设我现在连接的wifi名称为100ask，密码为12345678，则需要输入wifi -c 100ask 12345678

当网线插入开发板后，开发板的串口终端则会输出以下信息，表示有线网络已经连接成功
root@tinalinux:/# [ 3318.532310] sunxi-gmac gmac0 eth0: link is up - 100mbps/full - flow control rx/tx[ 3318.540797] ipv6: addrconf(netdev_change): eth0: link becomes ready 此时需要为开发板设备的有线网口获取ip，输入udhcpc eth0

当网线插入开发板后，开发板的串口终端则会输出以下信息，表示有线网络已经连接成功
