OAK-FFC-6P: No available devices

bitterisland6

Hi, I have a problem with the OAK-FFC-6P baseboard. I'm trying to go through the "Getting started" section of this tutorial. The setup that I have is almost the same as the one described there (I'm using OV9282-W instead of OV9282 cameras). The problem is, that when i try to run the cam_test.py script, it can't detect any device:

python3 utilities/cam_test.py -cams left,m right,m

Enabled cameras:

left : mono

right : mono

DepthAI version: 2.19.1.0.dev+0ac8dcd8248b13cf7d54ad3599daa69df8a54f4f

DepthAI path: /home/olo/.local/lib/python3.10/site-packages/depthai.cpython-310-x86_64-linux-gnu.so

Traceback (most recent call last):

File "/home/olo/jammy/praca/depthai-python/utilities/cam_test.py", line 209, in <module>

with dai.Device() as device:

RuntimeError: No available devices

I'm running the command on the host machine, with the depthai-pythonlibrary installed (installed dependencies both with commands provided in github README.md and withinstallrequirements.py script - everything executed while being on rvc3_develop branch).

The FFC-6P baseboard is detected on the host machine when connected (I have also installed the required udev rules)

The USB cable that I use for connection between the baseboard and host machine is the stock cable that I got with the FFC-6P (it's for sure connected to USB-3 port and cable is working as it was successfully tested with OAK-D W).

Here is the photo of the setup

The OS on the host machine is Ubuntu 22.04.

Okay. I fixed the problem by installing the luxonisos-1.9 OS image and flashing fip-oak-ffc-6p-rvc3-1.2.0.bin firmware.

I just received a FFC-6P and I have the same problem (no available devices) with the minimalest code sample:

import depthai as dai
device = dai.Device()

I followed the instructions here, I am in the rvc3_develop branch.

Another info : Only the "PG" LED is green, all the other LEDs are off.

Would installing the luxonisos-1.9 image and flashing the firmware solve the issue as indicated in the best answer of this post ? If so, where can I find documentation on how to do that ?

Thanks !

Hi apirrone
Good chance it would, yes. Docs here.

Thanks,

Hi jakaskerl

I reflashed the os and firmware with the latest version following the docs you provided.

I still get the same error, and the only led that is on is still the "PG" one.

Traceback (most recent call last):

File "<…>/test_6p.py", line 13, in <module>

device = dai.Device()

RuntimeError: No available devices

Any thoughts ?

Thanks !

FYI, I have the exact same issue with the other 6P we ordered.

apirrone

Hi guys, sorry to insist but I am still unable to use the two FFC-6P I ordered.

I had actually installed the luxonisos-1.11 (the latest available version) so I tried to install the luxonisos-1.9 version to match @bitterisland6 's configuration. It is still not detected, and now I can't ssh into the board anymore :/

I tried the older and newer ips without success

On the other 6P board we have, I haven't updated anything, I am able to ssh into it, and I noticed errors in the file ~/hddl_logs/hddl_device_service_0.log.last`

Any thoughts ?

Thanks !

Hi apirrone ,
You can't use 2x FFC-6P at the same time, as there's IP clash. Optionally, you can change IP of one, so both of them would work. For the .log, please create an issue on depthai-core.

Hi Erik, the two boards were never plugged at the same time. I can't ssh into them anymore after trying different versions of the os, should I try the recovery procedure?

erik

apirrone I see. I would proceed with the recovery procedure, as it seems something went wrong.

apirrone

Hi @erik, the recovery procedure went well, but I still have the same issues as before.

Thanks for your help !

apirrone Could you create an issue on depthai-core about this, and copy paste the terminal output? So firmware guys can help directly.
