Find IP address of your board¶

Note

This section assumes you have connected your board to a network with a DHCP server - e.g. your home network where your router is the DHCP server. Your board will be assigned a dynamic IP address which means it can change over time or if you reset your router or your board. In practice most routers Will assign the same IP address to the same device, the IP address may change and you will need to follow these steps again to find the new IP address for your board.

You can find the IP address in several ways.

Ping¶

The default hostname of a board is pynq. Your network may support hostname resolution. This means that if you try to connect to the hostname of your board, the hostname will used to lookup the IP address to the board.

From a command prompt or terminal on your host PC run:

ping pynq

This may automatically resolve the hostname to the IP address, and you can return to previous section to connect to your board.

Serial terminal¶

This is a good way to get the IP address of your board and general troubleshooting. Follow the instructions if you need help Opening a USB Serial Terminal.

Connect a USB cable and open a serial terminal to the board
Run the following to report information about the board’s network adapters

ip a

This will return info similar to the output below:

Check your router¶

You can usually find details of all devices on your network, including the IP address that has been assigned to each device. Check the manual for your router or look for log-in details on a sticker on your router.

Scan your network¶

Apps are available for smart phones and PCs that allow them to scan WiFi networks and identify devices connected to the network. This can be a convenient way to find the IP address of your board.

Search your App Store for “network scanner” or similar to find a suitable App. Fing which is available for Windows, Apple and Android is one example.
