Hi,
I am running into a NiC issue with the latest version of the Jetson AGX Xaiver Developer kit (32 GB) and hoping someone on this forum might be able to help solve it.
I have program that connects to an Ethernet camera and grabs images from it on a periodic basis (1 to 2 frames per second). Very slow! I have a 16 GB version of the Xavier Developer that runs this program without issue, for days. The 32 GB version does not. I has intermittent failures associated with the camera dropping from the network because the Xavier’s NIC had rx overruns and can’t seem to maintain a connection. I have 4 of the 32 GB Xaiver development kits and they all exhibit the same behavior. So, I do not believe it to be specific to a single kit, but rather a systemic issue with either the kits, the L4T version or Jetpack.
For my part, this is the same exact code running on both platforms except for that the 16GB version has Jetpack 4.2.3 installed, where as the newer 32 GB version has Jetpack 4.3 installed:
16 GB Xavier
* Linux 4.9.140-tegra #1 SMP PREEMT Tue Nov 5 13:37:19 PST 2019 aarch64 aarch64 aarch64
GNU/Linux
* Jetpack 4.2.3 → Release R32. Revision 2.3
* CUDA 10.0.326
32 GB Xavier
* Linux 4.9.140-tegra #1 SMP PREEMPT Mon Dec 9 22:52:02 PST 2019 aarch64 aarch64 aarch64
GNU/Linux
* Jetpack 4.3 → Release R32, Revision 3.1
* CUDA 10.0.326
Does anyone have similar issues, or run into issues like this? Did you solve it? If so what did you do?
Did anything change in the NIC drivers between the 4.2.3 release and 4.3 release that might help explain what I am seeing?I tried to find the kernel source to do my own diff, but can’t seem to find it. Where does the SDK manager download this code to?
Any suggestions on what I can do to debug this issue further?
