Hi christoph ,
I am not entirely sure. It looks like you connected cameras correctly, and command/cam_test execution was correct as well. 2 notes; could you try with latest main branch, and could you try with USB3 cable?
Thanks, Erik

    Hi Erik,
    I compiled the last main and ran it again. Basically the same output

    I also tried different cables. Seems to make no difference as well. The communication to the FFC seems also fine, so I hope this is not the issue.

    Any other suggestion? Anything I could check on the Hardware maybe.

    Best,
    Christoph

      Hi christoph ,
      Sorry about the issue, after checking a bit closer it might be that you got FFC camera modules that have ERRATA - could you check the markings on the voltage regulators?

      If that's the case, you can either cut the pin, or we can send you replacement camera modules.
      Thanks, Erik

        Hi Erik,

        thank you the information.

        So I definitely have the K28 mark on the voltage regulator U3 of all four cameras I do have. It seems like Pin 4 is already disconnected. I did not disconnect it, I guess it was delivered like this. It seems like I still have the issue that it is not detected. If it is possible it would be great if you could sent 4 new ones, what would be the approach to get them replaced?

          Hi Erik,
          so I got the replacement cameras, same issue. I think something is seriously wrong here. I realized that my SOM and FFC Board are turned 180 degrees to the picture on your website https://docs.luxonis.com/projects/hardware/en/latest/pages/DD2090.html. I added a picture to this thread so you can see it. I was wondering if you guys reworked the carrier board so that the SOM is switched 180 degrees now or if I got the part incorrect delivered? Is it save for me to turn the SOM, just wanted to verify, before I break something.

            Hi erik,
            I connected them similar to the picture above so I am pretty sure they are correct. For me it seems like the OAK FFC is working, at least the python examples are able to connect to it. Is there any way to check the subsystems individually? So we could at least see where the issue is coming from? My first idea was to connect the cameras to a rpi, just to see if I get a picture, but they seem to have a different size connector, so maybe this is also not a possibility. Could I flash the SOM Pro again and give this a chance, I am not sure if this is possible.

                Hi christoph ,
                Could you share again output of cam_test.py script eith the latest main version of depthai?
                Thanks, Erik

                    Hi erik,

                    so I went into depthai-python, pulled the last main, installed it wit pip and this is the output .

                        Hi christoph ,
                        Perhaps the reworked units weren't properly tested, but no other customer reported this issue - so it's strange it doesn't work as expected. If you have tried different cable connections (so it's connected properly), perhaps best if you send email to support again, and we'll try to send you units that weren't reworked.
                        Sorry for the inconvenience.
