100ASK-V853-PRO development board supports WIFI and wired network card
0. Preface
Through the previous chapter, we have successfully downloaded the Tina SDK package, completed compiling and programming the Tina Linux system, and then show how the 100ASK_V853-PRO development department can access the Internet through WIFI and wired network cards.

1. Use WIFI to realize Internet access
100ASK_V853-PRO is equipped with Allwinner XR829 on the full-featured bottom board. The burned development board system has been adapted and can be used directly. Enter ifconfig on the development board to display the enabled network devices.

After the enable is completed, because the system has built-in wifimanager-v2.0, you can quickly realize the network configuration, input wifi -h, and get parameter help

Next, you can scan wifi. Note that you need to check whether the antenna is installed before scanning. The installation position is shown in the figure below.
After checking that the installation is complete, enter in the serial port terminal of the development boardwifi -s

After the scan is completed, it will print Wi-Fi scan successful and the time used. You can see that the ssid in the output information is the scanned WIFI name. Note that if the WIFI name contains Chinese characters, it may not be displayed.
Next, you can connect to WIFI to access the Internet, enter wifi -c ssid [passwd], where ssid is the WIFI name, passwd is the password
Assuming that the name of the WIFI I am connected to is 100ASK, and the password is 12345678, you need to enterwifi -c 100ASK 12345678

It can be seen that when we complete the input, the development board will automatically connect to WIFI and automatically obtain an IP address. At this time, we can execute ping www.100ask.net to test whether the wifi can ping the official website of Baiwen.com, press Crtl+C to end the test.

2. Use a wired network card to achieve Internet access
For the wired network card, we have supported it in our patch file, but it is not enabled by default. We need to enable it manually. Enter the serial port terminal of the development board to view all supported network devices. We can see that after the ifconfig -ainput A device with an eth0 wired network card will appear.

Confirm that the device of the eth0 wired network card exists, and enter it at this time ifconfig eth0 upto enable the wired network card.
root@TinaLinux:/# ifconfig eth0 up

At this time, lead out a network cable from the router and plug it into the wired network port of the development board.
When the network cable is inserted into the development board, the serial port terminal of the development board will output the following information, indicating that the wired network has been successfully connected
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
At this time, you need to obtain the IP for the wired network port of the development board device, enterudhcpc eth0
root@TinaLinux:/# udhcpc eth0
udhcpc: started, v1.33.2
udhcpc: sending discover

At this point, we can execute ping www.100ask.net to test whether the wifi can ping the official website of Baiwen.com, and press Crtl+C to end the test.
