@Alex-Kushleyev I have now found the correct file in the /usr/share/modalai/chi-cdk directory. Now everything works as it should. Many thanks for your support!

@Alex-Kushleyev the chi-cdk directory does not exist. here is the content of the /etc/modalai/ directory:

voxl2-mini:/etc/modalai$ ls
extrinsics.conf voxl-camera-server.conf voxl-px4-hitl-set-default-parameters.config
extrinsics.conf.thermal voxl-cpu-monitor.conf voxl-px4.conf

@Alex-Kushleyev The most current file name in the list in the directory is com.qti.sensormodule.imx412_flip_2.bin.

We have ordered and installed this camera:

Image Sensor 4k High-resolution, Low-light Sensor for VOXL (Starvis IMX412 w/ micro-coax & M12-style Lens) (MSU-M0161)

@Alex-Kushleyev We use the ISP mode (“ae_mode”: “isp”) and the hires_small_encoded pipeline.
Thank you very much for your support.

@TomP Any ideas? There should be a rotation parameter somewhere.

Hello everyone,
I have accidentally turned my camera 180 degrees. Turning it round does not work because it is firmly attached to a bracket.
How can I rotate the video stream 180 degrees again? Where can I configure this?

Best regards,
Tom

@TomP Wonderful! So glad to hear. And I would really love to hear how the flight testing goes. We've never tried a VOXL 2 (or VOXL 2 mini) on a fixed wing (with ArduPilot) so be careful and triple check to make sure everything looks setup correctly before launching.

It is an honor for me to report. We will be careful. Of course, a crash can also occur independently of the VOXL2. This is a new drone that we are building.

What might be relevant for you is that we have found a gimbal that will fit one of your cameras with a bit of hardware hacking. The gimbal can also be controlled via serial interface using Ardupilot. We have already successfully tested this with the VOXL2-Mini.

voxl-2-io

It works! Many thanks for the great support!
The firmware upgrade was the solution.

@Eric-Katzfey said in ArduPilot on Voxl2:

@TomP A new voxl-ardupilot package with debug information added. But we may not need that. Try voxl-2-io detect and then if that is successful then try voxl-2-io scan

@Eric-Katzfey said in ArduPilot on Voxl2:

Yep, that all looks fine. Shoot. I may need to send you a new package with extra debug information to help debug this since by default there really isn't much we can see.

What do you mean by that?
"a new package with extra debug information"
