Setting Up Internet on BeagleBone Black via Ethernet Using an Ubuntu Laptop

Connecting the BeagleBone Black (BB Black) to the Internet via an Ethernet cable while using an Ubuntu laptop requires a few steps. This guide will walk you through the entire process, from connecting the hardware to configuring the network settings. If you have encountered difficulties with setting up the BB Black on Windows using a USB connection, we will show you how to achieve the same result with Linux.

Hardware Preparation

To begin, you will need a compatible wireless USB dongle with a Ralink 5370 chipset for initial configuration. This chipset is known to work well with BeagleBone Black. Additionally, you will need a standard Ethernet cable and a 5V power supply for the BeagleBone Black.

Step 1: Setting Up the Wireless Connection

Plug the compatible wireless USB dongle into the USB port of the BeagleBone Black. After the dongle is detected, follow the on-screen instructions to connect the BB Black to your Wi-Fi network. This is crucial as we need the BB Black to connect to the Internet before setting up the Ethernet connection.

Step 2: Disconnecting from Wi-Fi and Powering Down

Once the wireless connection is established, power off the BeagleBone Black. We will be powering it up using only the 5V power supply and an Ethernet connection from now on.

Step 3: Connecting the Ethernet Cable

Connect the BeagleBone Black to your Ubuntu laptop using the Ethernet cable. This will establish a direct network connection between the two devices.

Step 4: Booting Up the BeagleBone Black

Power on the BeagleBone Black using only the 5V power supply. This step is critical as it ensures that the BeagleBone Black is in a state where it can be configured as a network interface.

Step 5: Setting Up Network Configuration

Open a terminal on your Ubuntu laptop and use the GUI network settings or the command line to set up the Ethernet connection. In the terminal, use the following command to show the network interfaces:

ip a

Look for the interface associated with the Ethernet connection (commonly labeled eth0). If the interface does not appear, ensure that the Ethernet cable is properly connected and the network settings are configured correctly.

Step 6: Accessing the BeagleBone Black via SSH

Once the network configuration is in place, you can SSH into the BeagleBone Black. First, you need to find the IP address of the BeagleBone Black:

ifconfig

Note the IP address of the eth0 interface. Then, use the following command to SSH into the BeagleBone Black from your Ubuntu laptop:

ssh root@ip-address

Replace ip-address with the actual IP address you identified earlier. Enter the root password when prompted to access the command line interface of the BeagleBone Black.

Conclusion

By following these steps, you can successfully connect the BeagleBone Black to the Internet via an Ethernet cable while using an Ubuntu laptop. This method offers a stable and efficient way to manage your BeagleBone Black, especially for tasks that require a reliable network connection.
