VOXL 2 Camera Connected but Not Feed

[Wesley Gunawan]

Hi Tom, I only have the access to the device several days a week, please let me know the complete information you need if further information is needed. Here is the outputs requested:

voxl2:~$ cat /etc/modalai/voxl-camera-server.conf
/**

• voxl-camera-server Configuration File
• Each camera has configurations for up to 4 HAL3 streams:
• • preview stream for raw unprocessed images from CV cameras
• • small_video 720p (ish) h264/h265 compressed for fpv video streaming
• • large_video 4k (ish) h264/h265 for onboard video recording to disk
• • snapshot ISP-processed JPG snapshots that get saved to disk
• on QRB5165 platforms (VOXL2 and VOXL2 mini) you can only have 3 of the 4 enabled
• This file is generated from default values by voxl-configure-cameras.
• Do not expect arbitrary resolutions to work, the ISP and video compression
• pipelines only support very specific resolutions.
• The default video compression mode is cqp or Constant Quantization Parameter

@Wesley-Gunawan Hi Wesley, I faced a similar issue recently. I was using IMX678 Hires Camera in J7U. The camera was detected when I run voxl-camera-server -l, even the green led light on the sensor glows but I didn't get any data run I run voxl-inspect-cam -a. I had an alternate IMX678 camera and without changing any config, I replaced it and it worked. I don't know what is wrong with the first sensor. I should probably do RMA, but yeah, if you have another sensor, give it a try!

[Moderator]

@Wesley-Gunawan can you please share a picture of your setup? It needs to match a camera config found here: https://docs.modalai.com/voxl2-camera-configs/

Often when a camera can't be found:

1. it's installed backwards
2. the cable isn't fully connected or the connector is damaged
3. the wrong camera config has been configured during setup

[Wesley Gunawan]

@Moderator

Hi, the camera is connected correctly because when the configuration or installation setup isn't correct, voxl-camera-server wouldn't even detect the camera's connection, in this case it does, but no input from the camera has ever been acquired. Here is the image of the setup:

Is there any other information you need to help me debug this issue? It's been over a week and I need it working as soon as possible or else I have to return the whole kit. As for the camera defect possibility suggested by a user in this forum last week, I already tried swapping the camera and it still doesn't work.

[Moderator]

@Wesley-Gunawan It looks like you are using a C08 config. https://docs.modalai.com/voxl2-camera-configs/#c8---hires-only

Have you tried voxl-configure-cameras 8 ?

voxl-camera-server documentation for troubleshooting recommends running voxl-camera-server -d0. Can you try that and paste the output?

[Wesley Gunawan]

@Moderator It is camera configuration 8, the board wouldn't detect the camera otherwise (tried that before) so I'm assuming the camera configuration is correct.

@Wesley-Gunawan that looks like it's running properly. Can you open another terminal and run voxl-inspect-cam -a ?

[Wesley Gunawan]

@Moderator I already tried that in the past, even before I consulted this forum, the output has always been like this

[Moderator]

@Wesley-Gunawan Can you please set and run inspect-cam again?

[Moderator]

@Wesley-Gunawan did voxl-inspect-cam show anything while voxl-camera-server was running? it looks like you restarted voxl-camera-server while voxl-inspect-cam was running.

I think the proper steps are:

1. update config (done)
2. reboot VOXL 2
3. run voxl-inspect-cam -a

This is after power cycle (poweroff -f, power source off, turn on again)
