Testing the oak-ffc-4p device, I found that there is a issue at CAM_D.The issue is that the CAM_D will not respond after I restart the program.
Firstly, run the simple testing program:
depthAI version: v2.22.0
# os.environ["DEPTHAI_LEVEL"] = "debug"
import depthai as dai
pipeline = dai.Pipeline()
camMono = pipeline.createMonoCamera()
device = dai.Device(pipeline)
test_q = device.getOutputQueue("mono",4,False)
timer = time.time()
data = test_q.tryGet()
if data is not None:
frame = data.getCvFrame()
if cv2.waitKey(1) == ord('q'):
Then press q or ctrl-c to exit and rerun the program.
The reason why I think this is a hardware issue is that our team had lay a board that refer to the OAK-FFC-4P schematic which don't have this issue.
