NIC Delays issues

Hi all,

I am using a TX2 with Astro carrier board.

I connected my camera on the non native NIC.
Somes frames were dropped.

So i decided to use the native NIC & every things went ok.
And so by pinging an IP through the other NIC (the non native one) i saw there were losts of ping delays very high :

nvidia@tegra-ubuntu:~$ ping

Do you have the same issue ?
I think this is why i had frame drops.


i forgot to mention i am running l4T 28.2

Try the same experiment after maxing out performance (no energy savings):

sudo nvpmodel -m 0
sudo ~ubuntu/

Hi francoisBilberry,
Have you checked the bandwidth via iperf?


i am already in nvpmodel 0.
i also did jetson_clocks

i think more about a hardware issue but i may be wrong.
i will try to go on testing.

i stremaed my camera on one port & it seems ok. (native NIC of TX2)
on the other it seems NOK. (non native NIC)


We don’t have experience in using NIC display. So does it transmit frame buffers via ethernet or wifi? What do native NIC and non-native NIC mean?
