MIPI 2 lane CSI-0 and CSI-1 can't get video on Orin NX

[sammyb7qw7]

Our FPGA output 4 channel (MIPI 2 lanes) to Orin NX CSI-0~CSI3 on our Orin NX customer board.

But we only see the video2 and video3 on Orin NX.

But this FPGA had verify all video0~3 are working on our AGX Orin customer board.
We move the AGX Orin CSI setting to Orin NX, and we only see the video2 and video3 is working.
MIPI CSI-0 and CSI-1 can’t get video on Orin NX.

May I to know which AGX Orin CSI setting are different with Orin NX?
or any advice?

Please add “lane_polarity=6;” in the device tree of sensor mode for CSI0 and CSI1

Thanks

I had add “lane_polarity=6;” for CSI0 and CSI1 in our .dtsi, but it seem not work.
How to verify it?
Could I read register from Orin NX to double check it?

Get the trace log to check if get any data from the sensor.
