Oak D Pro W - Camera Not Detected on Socket Error

rovuser

Hello,

When trying to install DepthAI on my NVIDIA Jetson Nano I am getting an issue where the camera is not being detected on the socket. This is the case for all the cameras (RGB, Left, Right, Mono). Basically, I am trying to run any of the python files on the examples code in the depth ai repo but they all give me the same error and run into what seems like an infinite loop at around the point where the code is trying to access a video (e.g. in ColorCamera at rgb_video.py in videoIn = video.get() the program will just keep running until you stop it. Other than that, I downloaded everything necessary for the Jetson installation according to the documentation. Where is this issue stemming from? Additionally does the Jetson have the necessary architecture to support the Oak viewer gui?

This is depthai V3? The OAKs shouldn't have any problem running on Jetson. Oak viewer is not supported, since it only runs on x86 on linux.

Thanks,
Jaka

Yes. this is on depthai V3, everything is up to date but the issue is still happening. The USB connection is fine and the computer detects the camera connection, but the program detects no connected cameras.

Following up on this, I am not getting the socket issue anymore. It is now telling me this issue when running camera_preview.py:

$$
python3 camera_preview.py
Device name: OAK-D-PRO-W
Usb speed: SUPER
Connected cameras: [{socket: CAM_A, sensorName: OV9782, width: 1280, height: 800, supportedTypes: [COLOR, MONO], hasAutofocus: 0, hasAutofocusIC: 0, name: }, {socket: CAM_B, sensorName: OV9282, width: 1280, height: 800, supportedTypes: [MONO, COLOR], hasAutofocus: 0, hasAutofocusIC: 0, name: }, {socket: CAM_C, sensorName: OV9282, width: 1280, height: 800, supportedTypes: [MONO, COLOR], hasAutofocus: 0, hasAutofocusIC: 0, name: }]

RuntimeError: Cannot connect to device with name "2.1.3", it is used by another process. Error: X_LINK_DEVICE_ALREADY_IN_USE
$$

When running cam_test, the camera streams are at least showing up, but I am not sure why another process is using the device. When running ps aux | grep depthai only one process is showing up though so I am not sure why it is giving that issue. Additionally, when trying to kill the process, the device just changes its PID so not sure how to make sure only one process is using the device.
