Jetson TX2: Troubleshooting Ethernet Connection Issues
This article focuses on helping you diagnose and resolve Ethernet connection issues with your Jetson TX2 Developer Kit, specifically when connecting it to a laptop running Ubuntu 20.04 via an Ethernet cable.
1. Checking the Physical Connection
First, ensure that the Ethernet cable is properly connected to both the Jetson TX2 Developer Kit and the laptop. It's essential to double-check that the cable is not damaged and is working correctly.
2. Verifying Ethernet Settings on Jetson TX2
Access the Jetson TX2 and check its Ethernet settings. To do this, open the terminal and run the following commands:
sudo ip link set
sudo ip addr add
sudo ip route add
These commands will help you set up the IP address, netmask, and default gateway for the Ethernet interface.
3. Configuring Ethernet Settings on Ubuntu 20.04 Laptop
On your laptop, open the terminal and run the following commands to configure the Ethernet settings:
sudo nano /etc/netplan/01-netcfg.yaml
Modify the file as follows:
network:
ethernets:
enp0s3:
dhcp4: no
addresses: [/24]
gateway4:
nameservers:
addresses: [8.8.8.8,8.8.4.4]
Replace enp0s3 with your actual Ethernet interface name, and set the correct IP address and gateway for your network configuration.
After modifying the file, apply the changes with the following command:
sudo netplan apply
4. Pinging and SSH Connectivity
Now, try pinging the Jetson TX2 from your laptop and vice versa:
ping
If ping is successful, try connecting via SSH:
ssh @
5. Further Troubleshooting
If you still can't connect, try resetting the network manager:
sudo service network-manager restart
Additionally, you can check the status of the network interfaces:
nm
ip a
