I just connected a new PTZ camera to my raspberry pi. Unfortunately nothing seems to work.
Launching ‘python FocuserExample.py’ exits with an error.
Trying ‘raspistill -o image.jpg’ also results in the following error:
mmal: Cannot read camera info, keeping the defaults for OV5647
mmal: mmal_vc_component_create: failed to create component ‘vc.ril.camera’ (1:ENOMEM)
mmal: mmal_component_create_core: could not create component ‘vc.ril.camera’ (1)
mmal: Failed to create camera component
mmal: main: Failed to create camera component
mmal: Camera is not detected. Please check carefully the camera module is installed correctly
This is with the camera cable installed with the blue up. If I install it with the blue down, the red light comes on the camera, but I get a different error.
Also, from the other thread, I tried ‘i2detect -y 1’ but nothing is detected.
Here is how I connected the boards. Currently I don’t have the camera motors plugged into the PTZ board, but it didn’t work any differently when I did.
pi@raspberrypi:~/PTZ-Camera-Controller/pyCode $ python FocuserExample.py

The odd thing is, if I flip the cable going into the camera so the blue side is down, it seems to get further, but still fails:

Camera control callback cmd=0x4f525245mmal: No data received from sensor. Check all connections, including the Sunny one on the camera board
This is the correct connection method, but raspberrypi cannot receive the camera data. There are two possibilities:
1. The connection is loose
2. The camera is damaged
Please confirm the connection of the cable again, if the same error persists, please let me know, and I will let our sales staff contact you.
I’ve also tried with 3 raspberry pis now with the same issue.
I also confirmed the pi I’m testing with now worked with the generic raspberry pi camera. Also tried that cable with the PTZ camera, but no luck. Still get the red light coming on, on the camera board but the No data received error.
