I just received the FFC-3P with the IMX-378 and OV9282 (pair). The two OV9282's are attached to the CAM_L and CAM_R connectors and the IMX-378 is attached to the CAM_C connector. They are attached to the FFC-3P and the cameras with the conductors facing the boards. My understanding is the two main causes of the camera not being detected are the cable on the camera board coming loose and using an unsupported camera. Neither seem to be the case here.
The following is from running hello_world.py from the tuturial, but it happens with calibration and depthai_demo.py:
[1844301011713F0E00] [3.1] [49.351] [system] [warning] Calibration Data on device is empty
[1844301011713F0E00] [3.1] [49.567] [system] [error] Attempted to start Color camera - NOT detected!
LSUSB and device_manager show the movidius.
The cameras I received do not look like the ones in the photo. My sensors are connected on the same side of the board .
I'm using the main branch of depthai-python and depthai.
Any help would be appreciated.
