Confirm connector placement of MIPI CSI H3+H4

2026-06-10 7:04

Hi,
I have tried to bring up two OV9732 MIPI CSI cameras. I have come to a point where in principle everything has been tried. Driver and the whole pipeline is fully functional and I can read back that the cameras are streaming during capture but I get no data at all. Nor do I get any error flags or anything indicating something is not right with the signals from the cameras. The last thing to check is whether I have got the connector placement switched. From the wiki I see that the CSI0 (H3) is closest to the microphone and the CSI1 (H4) is closest to the Ethernet jack. Can you confirm that is the
case? It would be nice to have a component placement drawing with component names.

Thanks!

The interface shown in the illustration is CSI0, and the one near the RJ45 connector on the other side is CSI1.

In addition, are there any extra components in the MIPI signal path or are there any special considerations that can have an impact?

Thanks,
