RuntimeError: Failed to find device after booting, error message: X_LINK_DEVICE_NOT_FOUND with OAK-D Pro PoE

[YoshiyasuIzumi]

Check if issue already exists I found this post, but I couldn't solve my issue.

Describe the bug I run the simple python scripts in this section but I got following error.

Traceback (most recent call last):
  File "sample.py", line 16, in <module>
    with dai.Device(pipeline, device_info) as device:
RuntimeError: Failed to find device after booting, error message: X_LINK_DEVICE_NOT_FOUND

To Reproduce [Environment] PoE Hub: NETGEAR GS108PE (15.4W/port) Architecture: x86_64 OS: Ubuntu 20.04.4 LTS IP address and subnet mask: 169.254.1.1, 255.255.0.0 (Success to ping to 169.254.1.222) Python version: 3.8.10 Depthai version (installed by pip): 2.17.1.0

Run following scripts.

import cv2
import depthai as dai

pipeline = dai.Pipeline()

camRgb = pipeline.createColorCamera()

xoutRgb = pipeline.createXLinkOut()
xoutRgb.setStreamName("rgb")
camRgb.preview.link(xoutRgb.input)

device_info = dai.DeviceInfo("169.254.1.222")
device_info.state = dai.XLinkDeviceState.X_LINK_BOOTLOADER
device_info.protocol = dai.XLinkProtocol.X_LINK_TCP_IP

with dai.Device(pipeline, device_info) as device:
    qRgb = device.getOutputQueue(name="rgb", maxSize=4, blocking=False)
    while True:
        cv2.imshow("rgb", qRgb.get().getCvFrame())
        if cv2.waitKey(1) == ord('q'):
            break

Expected behavior A window show images captured by camera should be given.

I am running into the same issue with the ROS example (stereo inertial node) on jetson Xavier. I can run the camera just fine using the depthai_demo python script. For the ROS node, the camera is detected, and it prints the "Device Mx ID" but then fails after with the exact same runtime error mentioned above.

[hamzaMahdi]

I would like to mention, I have tried the ROS example on an x86 computer and it was fine. Could this be related to the fact that the jetson platform is ARM based?

[Luxonis-Brandon]

Asking. Sorry about the trouble.

[saching13]

@hamzaMahdi similar issue was seen here will be following up in that issue on ROS side..

[saching13]

@YoshiyasuIzumi is static IP set in this ? cc: @Erol444

[YoshiyasuIzumi]

@saching13 Thank you for your response. I don't change OAK-D Pro PoE's ip adress and I set my laptop's ip address to 169.254.1.1 (static). Please check attached image.

[YoshiyasuIzumi]

@saching13 I've tried with windows 10 environment as well but I reproduced same error. I can ping with camera successfuly but I got same error as well.

[themarpe]

@YoshiyasuIzumi Do you mind running the following example under depthai-python repository: examples/calibration/calibration_dump.py and post back the results

[YoshiyasuIzumi]

@themarpe I ran this code. Then I got following error. Could this code run with OAK-D Pro PoE?

Traceback (most recent call last):

[Luxonis-Brandon]

Sorry about the trouble.

Would you mind shooting an email to support@luxonis.com? We'd like to send you equipment that should help to debug what is going wrong here.

[themarpe]

@YoshiyasuIzumi

Sorry for the issue - do you mind checking out the branch eeprom_version_v7_multi_cam_support_4lane in depthai-python repository, then run the python3 examples/install_requirements.py and afterwards the python3 examples/calibration/calibration_dump.py

Also, do still shot over an email to support, referencing this issue, so we can debug this down further.

Thanks!

@Luxonis-Brandon @themarpe I am having the same issue with Oak-D-Pro.

I can run depthai_demo without any problem. Here is the output when I run depthai_demo.py

However, same launch file works on my own x86 machine, so I am a bit suspicious it is about arm64 & ROS.

@Luxonis-Brandon @themarpe I sent an email to support@luxonis.com a few days ago. So please check it as well. But let me share current situation.

I cloned depthai-python repository and checkout it to "eeprom_version_v7_multi_cam_support_4lane" branch. Then I ran "examples/install_requirements.py", I got the following error.

Traceback (most recent call last):
  File "install_requirements.py", line 39, in <module>
    import find_version
ModuleNotFoundError: No module named 'find_version'

So I tried the steps on README of depthai-python repo, then I successed to run "examples/install_requirements.py" and "examples/calibration/calibration_dump.py". Please check this output. response.txt

In this environment, when I run the simple python script in this section, I get the following error.

Traceback (most recent call last):
  File "examples/sample.py", line 12, in <module>
    device_info = dai.DeviceInfo("169.254.1.222")
TypeError: __init__(): incompatible constructor arguments. The following argument types are supported:
    1. depthai.DeviceInfo()

Invoked with: '169.254.1.222'

Please give me advice to setup. Thank you!

[Luxonis-Brandon]

Will check. Sorry about the delay.

[themarpe]

@YoshiyasuIzumi

Do you mind running some other script like so: DEPTHAI_LEVEL=debug python3 examples/ColorCamera/rgb_preview.py And if it doesn't work, post the log of that as well.

Otherwise, looks good on the output of calibration_dump.py

[YoshiyasuIzumi]

@themarpe @Luxonis-Brandon Thank you for your help. This script run successfuly and it provides color images! DEPTHAI_LEVEL=debug python3 examples/ColorCamera/rgb_preview.py

[themarpe]

Great - thanks for the follow up @YoshiyasuIzumi !

[samialperen]

Changing depth-ai version worked for me. https://github.com/luxonis/depthai-ros-examples/issues/57

[calebc01]

I'm running into this same issue when running the DepthAI demo on Windows10, connecting to the . When starting DepthAI, I hear an audible click in the camera, then this error dialog opens.

[Erol444]

Hi @calebc01, which OAK camera are you using? Which depthai version and which depthai repo commit? Thanks, Erik

[calebc01]

Hi @calebc01, which OAK camera are you using? Which depthai version and which depthai repo commit? Thanks, Erik

I'm using the OAK-1 PoE camera (link lights are on and I can ping it from the computer). I actually used the Windows installer to run all the setup, so maybe that's related. Looks like the default branch is labelled v3.2.0, on commit eefc4dfd77a6dc0a41010c098561268be74a07c1.

EDIT: I checked out the main branch and tried again, with the same affect. Here's what shows up in the terminal - it does see the device, but fails to connect:

[Erol444]

Hi @calebc01 , This is interesting. I would first try to update depthai (pip install depthai -U) and skipping version check with depthai-demo (python depthai_demo.py --skipVersionCheck). If that doesn't work, I would suggest looking at POE troubleshooting docs. Let us know if the issue will persist. Thanks, Erik

[calebc01]

Thanks for your help!

It looks like the issue was that we had the machine on WiFI and the camera on a cable. It shares a network, but maybe something caused the TCP connection to fail.

@calebc01 how to deal with it, my error may be is this , thank you

This was the problem for me:
