I also look others information, but i don not know how to resolv it.Could you give me some helps?
Thanks very much!
Is eth1 an add-on NIC? Or eth0? Is this wired through a switch and then router? What is the output of the “route” command? Can I verify the ping is being run from the machine with the 192.168.1.107 address (self-ping)?
Thanks for your answer!
I update OS image by sdkmanager, and add an usb interface by modify dts file.After compiled, only update dtb file.
eth0 is the origin network interface, and works.And eth1 is an add-on interface.
Following two machine get ip address from the same router:
Tx2 eth1 IP: 192.168.1.107
Another machine ip:192.168.1.181
before show:no buffer space available
192.168.1.107–ping–192.168.1.107: ok
192.168.1.107–ping–192.168.1.181: ok
after show:no buffer space available
192.168.1.107–ping–192.168.1.107: can not
192.168.1.107–ping–192.168.1.181: can not
192.168.1.181–ping–192.168.1.101: can not
Should i modify some configurations of network interface?
I have limited knowledge of the ethernet PHY (especially in custom setups). However, the “no buffer space” seems to me to be most likely a case of the hardware the buffer wants to talk to not being correctly wired, e.g., a signal pair swapped (I am assuming your device tree changes are valid, but invalid device tree might also cause such a thing).
On the other hand a very important piece of evidence is to verify that the 192.168.1.181 address was assigned by DHCP, versus knowing if it was assigned statically in the Jetson itself. How was the interface address assigned prior to failing? If you assigned it manually, then I’d say the wiring or device tree (or both) are incorrect, but if DHCP assigned this, then it becomes a mystery (but possibly incorrect physical wiring could be ruled out).
Note that dropped TX packets are for one direction, and perhaps RX is valid. In your case there are dropped TX packets, which would normally occur when traffic exceeds the connection’s throughput. A cut or missing wire will of course always have traffic exceed throughput (naming the wrong wire in a device tree is as good as a physically cut wire).
Btw, you might also post the output from this command for the non-working eth1:
sudo ethtool eth1
First: TX2 get ip address by dhcp. And i change device tree according to this blog(JetPack4.2.2系统上修改TX2配置为配置3_RMBR的博客-CSDN博客), and in Jetpack3.1, everything is ok.

There are a segment error about network adapter.1
Is there a reason the link is only running at 100Mb/s? This NIC is capable of gigabit, and if the router can handle auto negotiation, then this kind of sticks out. Although this is not an error, it is peculiar. Certainly a 10-to-1 reduction in speed, if gigabit is expected, could change behavior. Are you able to access this port’s setup through “nm-connection-editor”? If so, then perhaps you could go to the “Ethernet” tab and set “Link negotiation” to manual, followed by selecting speed as gigabit.
The dmesg logs indicates an outright kernel error. A driver did not respond and the watchdog software is complaining. The error is listed between the display controller unblank and eth1 starting, but doesn’t really offer a lot of clues.
If you monitor “dmesg --follow”, can you provide a log of what you see from bring eth1 down and back up?
sudo ifdown eth1
sudo ifup eth1
…I’m curious if the act of dropping or bringing up eth1 provides more clues.
First, Thank you very much for your patient answer.
sudo ifdown eth1:
[619.541868] r8168: eth1: link down
sudo ifup eth1:
[621.636440] r8168: eth1: link up
And i change eth1 speed to 1000M by mii_tool, The phenomenon still exists.
I read some blogs find that realtek NIC RTL8111e/RT8168 is not fully compatible with ubuntu18.04.
in Jetpack4.2.2, should i change NIC firmware version and which version is suggested for tx2?
I don’t know about the non-integrated NIC. There is a reasonable chance that if a firmware update is available (which would be through the NIC vendor) that this would be required; also, if there is some incompatibility with the driver, then the firmware might fix this (or require a completely new driver). I do not know about this particular chipset, but it would probably be worth researching this. Unfortunately I have no way to answer anything related to drivers for external or custom devices.
Considering the link down and up went without error, does networking then succeed after restarting the interface? If not, then I’m thinking there is some obscure wiring error. Firmware can be the equivalent of changing wiring if the wrong firmware release is used. Firmware being mismatched with a driver can also make a perfectly good driver fail as if it were the wrong API.
I had the same problem log.log (8.1 KB)
There is no such problem in nano r32.2.1, but there is such problem in tx2r32.2.1
Is this the development kit carrier board? Also, for the failure case, you might want to provide a complete boot log via serial console. Something did time out, but it is hard to say from that trace what it was which caused the failure to respond in time. For serial console information, see:
http://www.jetsonhacks.com/2017/03/24/serial-console-nvidia-jetson-tx2/
You might also want to describe the physical wiring scheme for the TX2 networking, e.g., wired ethernet going to a switch or going directly to a router (acting as a switch), and whether other hosts on the same network (since I see a ping which might be from a different system or from the Jetson itself) use the same subnet, so on. Anything which describes how the networks are wired.
hi all
I turned off the driver of r8168.c in TX2 r32.2.1, and my PCIe device will automatically recognize the driver version of 8169.c.This version has no problems and can be used normally
In R28. X, 8111 series drivers use 8169.c
