This question is about the combination of CSI-2 cameras that can be connected to the Xavier AGX. The Xavier AGX SOM has 6 camera processors and a total of 16 CSI D-PHY lanes. Is the following configuration supported:
Three 4-lane cameras (12 lanes total) and three 1-lane cameras (3 lanes total).
This fits within the 16 lanes available on the SOM, but may not work based on how the lanes must be connected to the SOM. Referring to Table 50 (CSI Configurations, D-PHY Mode) of the Jetson Xavier OEM Product Design Guide, if I connect one 4-lane camera to CSI 2&3, another 4-lane camera to CSI 4&5, and a third 4-lane camera to CSI 6&7, that leaves CSI 0 and 1 (4 lanes total) for the three 1-lane cameras. The design guide says I can place a 1-lane camera where each 2-lane camera is shown (shaded in green), but can I split a 2-lane bundle into two 1-lane interfaces? The total camera count would be 6, which is the limit, but can the lanes be assigned as I show? Or would I be limited to only two 1-lane cameras?
I think I cannot do it because the clock for each CSI interface is for both lanes of each CSI, so I can’t split a 2-lane CSI into 2 separate cameras.
