error message: X_LINK_DEVICE_NOT_FOUND

Nemo

Hi,

I get the following error when i try to run the demo application from depthai. I have oak FFC 6P board and im using rvc3_develop branch, also tried develop branch. Im able to ping and ssh into the oak board. I also did installed all the requirements as mentioned in documentation.

RuntimeError: Failed to connect to device, error message: X_LINK_DEVICE_NOT_FOUND

Best Regards,
Nemo

Hi @Nemo
Please run journalctl -u depthai_gate and paste the log here.

Thanks,
Jaka

Nemo

I get the following.

-- Logs begin at Tue 2023-11-21 22:10:22 CET, end at Wed 2024-02-07 14:36:27 CE>

-- No entries --

Im using USB 3.0 cable. Should i do any os update as shown in the docs before first use Luxonis RVC3 / S3 Dev Kit and Getting started - Google Docs .

Best Regards,

Nemo

MatevzMorato

@Nemo please update to the latest available OS (https://luxonisos.fra1.digitaloceanspaces.com/index.html?prefix=release/1.14/) then reboot the board and your issue will hopefully be resolved.

Nemo

@MatevzMorato I updated and still i get this problem. Any other checks i can do to find the root cause of the problem?

One more additional information, I can only see PG LED glowing, is that alright?

MatevzMorato

@Nemo could you run systemctl status depthai_gate and post the output again?

As well as the output of python3 -c "import depthai; print(depthai.__version__);"

Nemo

Hi,

I get
systemctl status depthai_gate
Unit depthai_gate.service could not be found.

python3 -c "import depthai; print(depthai.__version__);"

2.23.0.0.dev0+8d005436cd31d671f33b4a2f2aad50383a895eea

jakaskerl

Hi @Nemo
If you have installed the OS, you should have depthai_gate service enabled. Just to be sure, are you are running the command from inside the device? Running this on your PC would result in the output you have provided.

Thanks,
Jaka

Nemo

HI,

sorry for the confusion>

@Nemo are the two devices on the same subnet?

Do you want to run your app directly on the FFC 6P or do you want to run it from host?

Nemo

MatevzMorato
yes, Im trying to run from host device (jetson nano)

MatevzMorato

Interesting, that should work then.

Are the devices on the same subnet? I mean the FFC6P and your jetson nano.
You have the FFC6P connected directly to the Jetson right?

Nemo

MatevzMorato Yes its on the same subnet, I can ssh into it from my jetson. FFC6P is connected to jetson usb.

Also, when i run list_devices, i get the following output.

desktop:~/depthai-python$ python3 list_devices.py

but when i run cam_test.py as mentioned in the documentation i get the following output.

Hi @Nemo
Very strange..
Could you try some standard RGB or Mono examples at depthai-python/examples/*. Also manually specifying the IP using with dai.Device(pipeline, dai.DeviceInfo("192.168.197.55")) as device:

Thanks,
Jaka

Nemo

I get the following:

Nemo

@**jakaskerl @MatevzMorato @erik

Is there any other possibilities, which I'm missing out for this error?**

MatevzMorato

@Nemo sorry for the delay.

After an attempt to run the app, could you please run this again, on the RAE itself and send the output over?
