I recently worked on AGX xavier,L4T 32.3
I want to use two chips gmsl Deser 9296 with 8 cameras. which use Ser9295.
But I am not sure how to setting the vi and csi currectly…
Our hardhare design is fist 9296/9295 uses 4 lanes csi A+B
the others use csi C+D.
Thanks for your reply.
If I use 8 cameras,the port of VI should be 0-7 and the channel should be 0-7 ?
Now I can get 8 video point,it was video0-7,there is only four video point(video[4-7]) which are one group can get the video streaming.
When open video0-3,it occur an error.

thanks for your reply
I had solved this issue.
But I have a little confused.
The official introduction platform has 16 VI ,I connect 8 cameras why vc-id should be 0-3 only.
Could you help explain that ?
The CSI 2.0 spec tell the VC-ID is two bit.
Jetson have 6 CSI 2 lanes can connect 6 bridge like 9296, should be able support 6x4 =24 sensors
But for the performance issue we only support to 16.
