The TX2 eth0 can not ping other ip,and other pc can not ping the TX2.
In kern.log I find the eth0 is only 100Mbps, it is abnormally.
How can I debug this problem,and How to know the hardware is normal?

Some ethernet cards will require a “crossover” cable to connect directly. I’d suggest first adding a switch in if you can, or if not, then try a crossover cable. Possibly this is an issue.
I’ll need to the “ifconfig” and “route” output from both the Jetson and the host PC (the two work together). Also, verify that you’ve set your host PC up to act as a DHCP server (or that you’ve assigned a static IP address to the Jetson…without a router this is mandatory for the Jetson to have an address). Also verify if the micro-B USB cable is connected from Jetson to host PC.
There have been cases in the past where some high end managed switches have options not compatible with all ethernet, and there have also been rare cases where inexpensive older network hardware has had some unidentifiable fluke causing an error. Were you able to confirm eth0 works with different network hardware? I’m not sure if you consider this closed from your view or not.
