RuntimeError: Failed t...after booting, error message: X_LINK_DEVICE_NOT_FOUND

CodingArcher

Hi,
so i am having the following issue:
python3 main.py [192.168.1.7] [88.288] [system] [warning] Calibration Data on device is empty Conected to 192.168.1.7 Conected to 192.168.1.6 Conected to 192.168.1.5 Traceback (most recent call last): File "main.py", line 27, in <module> device = stack.enter_context(dai.Device(pipeline, device_info)) RuntimeError: Failed to find device after booting, error message: X_LINK_DEVICE_NOT_FOUND

This is the code i have been using:

import pprint

import cv2
import depthai as dai
import contextlib

# Start defining a pipeline
pipeline = dai.Pipeline()

# Define a source - color camera
cam_rgb = pipeline.createColorCamera()
cam_rgb.setBoardSocket(dai.CameraBoardSocket.RGB)
cam_rgb.setResolution(dai.ColorCameraProperties.SensorResolution.THE_1080_P)
cam_rgb.setInterleaved(False)

# Create output
xout_rgb = pipeline.createXLinkOut()
xout_rgb.setStreamName("rgb")
cam_rgb.preview.link(xout_rgb.input)

q_rgb_list = []

# https://docs.python.org/3/library/contextlib.html#contextlib.ExitStack
with contextlib.ExitStack() as stack:
    for device_info in dai.Device.getAllAvailableDevices():
        device = stack.enter_context(dai.Device(pipeline, device_info))
        print("Conected to " + device_info.getMxId())
        # Output queue will be used to get the rgb frames from the output defined above
        q_rgb = device.getOutputQueue(name="rgb", maxSize=4, blocking=False)
        q_rgb_list.append(q_rgb)


    while True:
        for i, q_rgb in enumerate(q_rgb_list):
            in_rgb = q_rgb.tryGet()
            if in_rgb is not None:
                cv2.imshow("rgb-" + str(i + 1), in_rgb.getCvFrame())
        if cv2.waitKey(1) == ord('q'):
            break

To my hardware:
PC: Ubuntu 20.04 LTS
2x OAK-D POE
1x OAK-1 POE

I also get duplicate IP addresses when just getting all connected devices listed. not sure how to go about this

Hello CodingArcher ,
this is really strange, we apologize for this inconvenience. We have 2 questions in order to debug this as quickly as possible:

How many networks interfaces do you have? Output of ifconfig would be very helpful here
Have you tried using any of the example code (so running on just 1 device)? We are interested if it works as expected.

Thanks, Erik

Hi Erik,
thank you so much for getting back to me so soon.

And then you have asked me to run it with only one device, which i used a OAK-1 POE and it worked as intented.
❯ python3 main.py [192.168.1.7] [7360.230] [system] [warning] Calibration Data on device is empty Conected to 192.168.1.7

Could it be because im having OAK-D and OAK-1 POE combined? i would assume that that should not be an issue.

Kind regards,
Markus

erik

Hello CodingArcher ,
so the 2x listing is because you are connected to the same network via 2 interfaces (wifi and ethernet). This is a bug in our bootloader that should be fixed this/next week, thank you for finding/report it!
I would suggest trying to disconnect from the WiFi network and try running the multiples POE devices code again. If that doesn't work I'm really interested in the output (if it's any different).
Thanks, Erik

CodingArcher

Hi erik
Oh always the small things. Ive now disconnected form wifi and we can see that it actually only gives me 1 IP address back.
❯ python3 main.py [192.168.1.7] [904.691] [system] [warning] Calibration Data on device is empty Conected to 192.168.1.7 Conected to 192.168.1.6 Conected to 192.168.1.5

Not sure why the OAK-1 POE has no calibration.

thank you so much for the help. looking forward to that fix

regards,
Markus

erik

Hello CodingArcher,
thank you, it's great to know this fixes it - we will add it to our POE troubleshooting docs. I just have a final question; were you connected to the same LAN via the WiFi and ethernet? That's quite strange, but I assume that's what happened since the device discovery found every device twice.
Thanks again, Erik

CodingArcher

Hi erik ,
yeah i was on the same network. I didnt realise that Ubuntu 20.04 doesnt just kill the wifi connection when pulled into ethernet.

So my network is the following:

router -> ethernetcable -> POE switch -> Host PC (Ubuntu 20.04)
---> wifi ---> Host PC (Ubuntu 20.04)

Hope that helped for the documentations 🙂

Cheers,
Markus

erik

CodingArcher makes sense, I thought that would be the case.
Thanks again for checking! Erik
