[BUG] OAK-FFC-6P RVC3 No available devices

[RaymondCM]

We received two OAK-FFC-6P devices today. Neither of the devices work in any of the following configurations:

• depthai-python (on the rvc3_develop branch)
• depthai-core (on the rvc3_develop branch)
• depthai-core (on the rvc3_develop branch) and updating the OS to 1.10 and the FIP to latest
• With no modules plugged in or with one or multiple
• With DC and USB input or with only USB input

We can successfully ssh into the device, but we cannot get either depthai-core examples or depthai-python utilities or examples to discover the 6P device.

Expected behaviour of plugging in the device and installing the development branch of rvc3 support was for the camera to be connected. Neither 6P device, whether updated, nor works.

@RaymondCM

Please run with following set: DEPTHAI_LEVEL=debug utilities/cam_test.py --cameras rgb,c

Also, make sure that you have installed examples/install_dependencies.py under the selected rvc3_develop branch

[RaymondCM]

@themarpe - install deps was run, no difference all 3 6P boards. Cameras are accessible via SSH on 192.168.197.55 despite their SSH host key rotating.

@themarpe Any update? We can successfully get the devices to work on Windows, but not Linux based systems.

[themarpe]

@RaymondCM wrt Linux, if you can ssh - I assume it has to do with firewall blocking UDP broadcast. I'd check that first (port 11491).

Otherwise, we are transitioning away from ETH adapter approach into native bulk USB EP's, but will take a bit longer to have ready. This will however drastically improve UX and interoperability

[RaymondCM]

@themarpe This was the issue. I can now see the device.

As a note, the port mappings (CAM_D is CAM_F) are wrong, i.e. an IMX477 in CAM_A doesn't work, but in CAM_D launched with CAM_F does work. The device at the moment is incredibly delicate, with intermittent connection issues and multiple cameras not working (defeating the purpose of the 6P board!), I.e. IMX477 in CAM_F only supports a single mono camera being plugged in, any more and everything breaks. I think the switch to USB will be helpful!

Also having an issue where the Xout Queue only provides a single frame and is then empty. I'll close this issue for now waiting for a more stable device.

[RaymondCM]

For context, the single queue issue was due to colour preview being enabled (resulted in RTEMS_FATAL_SOURCE_ASSERT)

Hello, I have the exact same problem that @RaymondCM had, but I can't seem to fix it (I'm on linux).

• depthai and depthai-python are on the rvc3_develop branch
• only the PGLED is lit, the others are unlit
• I tried to update the os and firmware and nothing changed
• disabling the firewall changed the error I got

My test_6p.py file consists of only two lines :

import depthai as dai
device = dai.Device()

SSHing into the device, I noticed have the following errors (no pcie device found in XLinkPlatform.cpp) reported in hddl_device_service_0.log

Any idea of what's going on ?

Thanks !

[themarpe]

@apirrone

Which OS are you currently on? (on device: cat /etc/os-release)

You may update by transferring latest 1.11 (https://luxonisos.fra1.digitaloceanspaces.com/release/1.11/luxonisos-1.11.dm-verity.mender) to device & flashing with mender -install [os.dm-verity.mender] && reboot

[apirrone]

Hi @themarpe, I am on Ubuntu 22. I already tried flashing this version of the os, did not work :/

Thanks !

[apirrone]

I tried again to install the 1.11 version on the second board I ordered. It still does not work and now I can't ssh into it anymore

[themarpe]

@apirrone I'd suggest trying the flashtool method - CC: @jakaskerl for instructions

[apirrone]

Hi @themarpe .

I followed the recovery procedure with flashtool as explained here :

(I used the latest available luxonisos version, luxonisos-1.12.zip and the fip-oak-ffc-6p-rvc3-1.2.0.bin fip )

The procedure seems to have been successfull

But I still have the exact same problems as before : no available devices, I still can't ssh into the board with ip 192.168.197.55 and only the PG LED is lit.

What's next ?

Thanks !

@RaymondCM why was this ticket closed, I have the OAK-FFC-6P and am using the rvc3_develop branch and have installed the correct requirements and I can not get the device to be recognized at all. Any luck yourself how can I pull up the cameras?

[sferoze]

@apirrone I am having the same issue the PG led is lit but the other unlit and the device is not recognized.

[RaymondCM]

@sferoze Ensure your firewall is disabled, update the camera firmware over SSH, unset the manual connection information in your system settings and leave auto DNS. If this still doesn't work, follow the instructions here to manually set it up. Verify your camera is connected by checking SSH connection.

[RaymondCM]

@apirrone follow the instructions in the link above. If you still cannot connect, verify your network settings and firewall. You shouldn't need to set the IP manually with the latest firmware, I find it's best to update the device when SSH'd in, once you get it working.
