4. Connection[edit source]

Connect the micro USB Type-B to USB Type-A cable between your laptop and the ST-LINK/V2-1 port of the board
Connect the USB Type-C™ to USB Type-C™ cable to the 5V/3A power supply
Connect the USB Type-C™ to USB Type-A cable betweenn your laptop and the USB Type-C™ OTG port of the board
Optionally connect the Ethernet cable between your Ethernet network and the Ethernet port of the board

5. Check the host computer Internet access[edit source]

An Internet access through http and https protocols must be provided.

The command below allows to check for Internet access through http/https protocols:

 wget -q www.google.com && echo "Internet access over HTTP/HTTPS is OK !" || echo "No internet access over HTTP/HTTPS ! You may need to set up a proxy."

If a 'OK' message is returned, the network is well configured. In such case, skip the rest of this section and jump to next one (Install extra packages).

Any other situation likely indicates the need for a proxy for http/https protocols.
The best solution to set a proxy for http/https protocols is via the shell variables http_proxy and https_proxy:

 export http_proxy=http://<MyProxyLogin>:<MyProxyPassword>@<MyProxyServerUrl>:<MyProxyPort>
 export https_proxy=http://<MyProxyLogin>:<MyProxyPassword>@<MyProxyServerUrl>:<MyProxyPort>

Check again the Internet access with command:

 wget -q www.google.com && echo "Internet access over HTTP/HTTPS is OK !" || echo "No internet access over HTTP/HTTPS ! You may need to set up a proxy."
