Hi,

I am trying to connect my Jetson Nano 2 GB with Raspberry Pi 3B(Not +) The expectation is to connect each card at 100 Mbps Full Duplex. However, I can’t get to any reasonable point at connecting each other. I can connect RPi with the same cable and config to my Ubuntu Laptop. However, I can’t connect to to Nano.
Below is the out put of ethtool of Nano:
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Supported pause frame use: No
Supports auto-negotiation: Yes
Supported FEC modes: Not reported
Advertised link modes: 10baseT/Half 10baseT/Full

1000baseT/Full
Advertised pause frame use: No
Advertised auto-negotiation: Yes
Advertised FEC modes: Not reported

Also this is the output of RPi ethtool:

I tried both cross and straight cables. Straight detects the link.

What do you see from “ifconfig” and “route” on both the Jetson and the RPi? Without a router you’ll need to make sure both systems are correctly assigned addresses.

That’s the problem! Not sure how but, although the address that I entered through the edit network connections gui shows, ifconfig is showing the opposite. Couple of times taking the eth0 from dhcp to manual, the nano, realized there is an ip. ifconfig hows the ip and It works now. Thanks for your help.
