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

Robotic kit for Raspberry Pi

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.

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.
