Can tx2nx support 8 lanes to capture the frames

Can tx2nx support 8 lanes to capture the frames in jetpack 4.6 or later?

hi AlfredNG,
Yes, you can set 8lanes in TX2 NX, need set in DTS and VI driver will adopt that, reference

Hello!
I know that. But I don’t know when I use 8 lanes, if I can use “/dev/video0” or “/dev/video0”+"/dev/video1" to capture the frame?
If “/dev/video0”+"/dev/video1" maybe very slowly.
When I use 8 lanes,(csi0+1+2+3), which clk do I use? clk0 or clk2?

Using video0, and for clock you don’t need to handle the driver will handle it. And clk0 and clk2 both need enable.

Hello,I know the clock will handle it . But I connect to fpga that should know that. That means clk0+clk2.

Right you can take them as two independent source but capture to one 2x size buffer.
