Pi Dog camera is not being detected. Rest of PiDog is working great!

Robotic kit for Raspberry Pi
1

Assembled the PiDog and everything works except the camera.

I checked the connections based on the diagrams and photos in the forums. They look same except instead of blue color on one side, the cable connector is black on one side.

Here are the outputs from the Pi 4 B.

Let me know if you need any more info.

Thanks,

Can you provide photos of both side of cable connected. The coloured side must be in top, on the same side than the lock.

@SunFounder_Moderator Is this issue because of connections or the camera module?

Thanks,

Please provide images of your camera wiring to help us diagnose the problem.

We suggest trying a different FFC cable to see if the camera is then recognized and works.

To test the camera, please run the libcamera-hello command.

@SunFounder_Moderator I have posted images of the camera wiring earlier in this thread.

libcamera-hello output is also in thread.

Unfortunately, I don’t have another FFC cable. I did take it out and tried to connect it couple of times but the camera is not detected by the Pi in libcamera-hello

I had a similar problem. Directly above the camera lens there is a tiny flat cable with a rectangular tan coloured tab on the top end. The back of the tab is a connector that plugs into a tiny connector behind it. Press on the front of the tab and it may snap into the connector,
That worked in my case.

Thanks Rob. I finally solved this using a new cable and reconnected everything again.
