ConnectCore 6UL Eth0 NetworkManager Problem

0 votes
I am having trouble using the ETH2 port on the ConnectCore 6UL Pro.

From what I read, the Ethernet hardware is mapped to Linux like this:

PHY | LINUX
ETH2 | eth0
ETH1 | eth1

So, in Linux, I tried to connect to eth0 (which uses the physical ETH2) using networkManager (nmcli). I set a static IP, manual ipv4 method and connect. With eth1, this works 100% of the time.

With eth0, I can see the connection using `nmcli con show` but in `ifconfig eth0` I see no ipv4 address assigned, and the connection does not work. I can then assign an IP to eth0 with `ifconfig eth0 ###.###.###.###` and the connection will work for a few seconds. After those few seconds, the connection disappears from `nmcli con show` and the IP disappears from `ifconfig eth0`.

What Is up with ETH2 (Linux eth0)? Is there something I am missing when setting this up in Linux? Is there something I should be doing in the device tree when compiling the OS?
