I’m unable to bring up Jetson AGX Orin Devkit onboard ethernet. Similar cases and documentation I’ve been able to find on this forum relate to custom carrier boards and their device trees which I not using. I have the default P3737 carrier board with P3701 module as per Jetson AGX Orin [32GB developer kit version]. The ports rx/tx lights appear permanently illuminated and reflashing (both JetPack 6.0 DP and JetPack 5.1.3) has made no difference.
I’ve listed some relevant commands and outputs below: dmesg:
[ 12.569313] mdio_bus 6810000.ethernet: MDIO device at address 0 is missing.
[ 12.569328] nvethernet 6810000.ethernet: failed to connect PHY
[ 12.569332] net eth0: ether_open: Cannot attach to PHY (error: -19)
nmcli:

Attempting to bring interface up with ip link set eth0 up results in same dmesg output as listed above :
RTNETLINK answers: No such device
I’d appreciate any insight on what may be causing this - happy to provide additional detail if required.
Hi,
Have you checked the corresponding device tree? I suspect that the problem is caused by the PHY chip. Is the PHY chip welded properly? Has the pin of the chip been measured?
As for the soldering of the PHY chip - since this isn’t a custom carrier board I wouldn’t expect any issues here. Would this require me to measure voltages coming to U2701? Which test pads could I use to verify correct soldering/voltages?
