DISTRIB_DESCRIPTION=“Ubuntu 18.04.2 LTS”
Our equipment is as follows:20 tx2 boards, even on a switch.with 100M/bit Ethernet cable;
One of the ping another, The results are as follows:some time the ping delay is so big,After a few seconds,ping delay is restore normal.
We run the same software on TK1 board is no problem.but now update with TX2-4Gb had this problem.
Our switch chip is BCM53286XM-20FE Ports+4 GbE Interface.We determine It’s not a switch problem.
Our software is processing the video stream,with rtsp or 28181 agreement.
Thanks for your answer.
1.Can i only update Kernel and DTB file ? because upgrade sdkmanager all of 20s TX2 modules is so difficult.
2.Sorry i can’t set up the test environment.we have’t enough nvidia devkit.
Thanks for your answer.
1.sorry ,we can’t do the test.because which Involves update our software,so diffcult .Finally, if no other way I can do this test.
2.sorry we can’t do the test,on our board ,the switch is fixed connection with TX2.
Tomorrow we will update kernel an dtb file of 20 tx2 modules to test.
In addition,if not run our software ,ping is normal dealy. but we used tk1 board have’t this problem.
Hi,
Please do not compare TK1 with any board on rel-32 anymore. The software on TK1 hasn’t been updated for 3 years. TK1 case does not help here.
You need to share more detail about your software or we may not able to help you.
Also, it does not make sense to upgrade all 20 TX2 modules if you claimed the issue can be reproduced by 2 pieces of TX2.
Why not just power down other TX2 and make test?
Thanks for your answer.
Because if recompile our software is trouble, our software is very large, and if it doesn’t cooperate with the new SDK, it will be very trouble.
and if we only run two TX2 is so difficult ot reproduced.we need to deal with more than 20 channels 1080P video, it is good for it to reproduced the problem.In this case,every ten minutes or so will appear again .
So, only upgrade kernel and dtb file is the fastest best test.
Thanks for your answer again ,Please wait for our test results.
Hi,
What kind of “software” are you talking about here if kernel and dtb could be the official one?
not the official one,just i doubt whether the kernel driver bug.
Had a discussion with 504566020 over forum private message.
Here is a brief description of this system.
-
20 tx2 nodes. One of the TX2 devices is a master node with extra PCIe based 1GbE NIC and remaining 19 nodes as child nodes.
-
The video stream will pass through the PCIe NIC on the master node to the switch and then to child nodes.
-
Each child node will process at most 4 video stream and each stream is with size 2MB. After the process, child nodes will send the result back to master node.
-
This issue only happens when total stream # > 30 and with data from real camera. When error happens, each node will have ping delay up to 1000 ~10000 ms.

Hi,
Please check if you would see the increment in mmc_rx_fifo_overflow when you hit the error.
Hi,
mmc_rx_fifo_overflow no increase.
we run “watch ‘date >> txt.txt;ethtool -S eth0 >> log.txt;’” when delay error is recurrenced.

Hi,
During the test, did you enable jetson clocks and nvpmodel to mode 0?
not enable jetson clocks and nvpmodel to mode 0.
But I have tested nvmodel mode 0.Has no effect on this error
But I have tested nvmodel mode 0.Has no effect on this error
Do you remember to run jetson_clocks but not only the nvpmodel?
only run“ nvpmodel -m 0”.
