Ethernet setup Drive AGX Thor devkit SKU10

Hi @rforsberg
We had the same trouble, getting the network running and assigning a static IP.
For us the only Connection that worked was the Eth 1 connector as shown in your image.
This mapped to mgbe2_0:

mgbe2_0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1466
        inet 192.168.178.5  netmask 255.255.255.0  broadcast 192.168.178.255
        inet6 fe80::4ebb:47ff:fe5c:7586  prefixlen 64  scopeid 0x20<link>
        ether 4c:bb:47:5c:75:86  txqueuelen 1000  (Ethernet)
        RX packets 7230  bytes 586525 (586.5 KB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 1173824  bytes 104443441 (104.4 MB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

This is our netplan config:

network:
  version: 2
  renderer: networkd
  ethernets:
    mgbe2_0:
      dhcp4: no
      addresses:
        - 192.168.178.5/24
      gateway4: 192.168.178.1
      nameservers:
        addresses:
          - 8.8.8.8
          - 8.8.4.4

Hope that helps
