I just bought an Nvidia Jetson AGX Xavier, and it arrived a few days ago. I successfully installed JetPack 4.1.1 with the other included packages (Cuda, opencv, etc.) using the connection via USB-c through the host option (running the host in Ubuntu 16.04).
After booting, the Ethernet port does not seem to detect any connections at all. I rebooted the access point and tested the connection with another device using the same port and Ethernet cable, and it works perfectly with that other device. The switch even has an light indicator which turns on when a device is connected, and it turns on with the test device I used; however, it fails to do so with the Nvidia Jetson AGX Xavier.
I even tried out all the solutions discussed in this forum with no success. I also tried to reflash the device but now using the connection through the Ethernet cable option for the other included packages, and, as expected, it can only install the OS but not the other packages (because the OS is installed though the USB-c connection).
I followed anti ESD precautions during the whole process. Is this a possible manufacturing error?
