Hello,
we are using production som jetson xavier-nx on our custom carrier board.
We observed that when RJ45 cable is connected network status updated as shown below
if RJ45 cable is removed then the network status updated as shown below
There is no update in status bar, but it updates in case of development som. Please refer pic below
What could be the issue? Please guide us to fix this issue.
Hello,
Any updates on above please?
I probably can’t help with a fix, but I will suggest that if you run “dmesg --follow”, which continuously shows log additions, that seeing the output at the time of the failure might offer clues.
Additionally, device tree normally controls lane routing for various pins which have multiple function. I am guessing that if it runs ethernet at all, then device tree might be valid. However, if the ethernet is brought up and back down every time, then it might be related to device tree incorrectly routing lanes.
Another possibility is signal quality. If the interface is not the correct impedance, or is too long, or has too much inductance or capacitance, then the signal quality will drop.
Thanking you for the response linuxdev,
We’ll consider your suggestions.
