@Alex-Kushleyev I'm unfortunately still seeing the same result with no cameras being detected from voxl-camera-server -l. I've tried J6 with the Lower slot on M0084 and the appropriate camera config which loads the correct .bin file to /usr/lib/camera/. I get the same result with both the AR0144 and the OV7251. Though I do hear the OV7251 when it's connected. Any other ideas you have to try other than replacing the M0084 connection cable?
