    Ok i resolved the issue. You actually need to run voxl-mavlink-server and voxl-vision-px4 to get Autopilot enabled for Mavsdk.

    Hi, You will need to install the openmp package for voxl which can be found here http://voxl-packages.modalai.com/stable/. The easiest way to do this would be to follow these steps: Edit the /etc/opkg/opkg.conf file and change the last line from src/gz modalai http://voxl-packages.modalai.com/dists/apq8096/stable/binary-arm64/ to src/gz modalai http://voxl-packages.modalai.com/stable/ Run opkg update Run opkg install openmp Redit the /etc/opkg/opkg.conf file to change the last line back to the original i.e. src/gz modalai http://voxl-packages.modalai.com/dists/apq8096/stable/binary-arm64/ Rerun opkg update Let me know if there are any issues.

    Hi @ryan-langlois1 , I don't know of a way to do this at this point that is equivalent to say a hard drive clone... In general, we are doing this using Yocto/Bitbake to generate the original system image, and customize it using recipes etc. In our production line, we flash the bare minimum system image, and then load debian packages needed to get the functionality that we want. We do this via the "Platform Release" (https://developer.modalai.com/). There's a few scripts and a bunch of packages in there, you can see this for reference, e.g. the offline-install.sh is a good example: [image: 1660146627309-1c84cb2c-e2ad-4281-b5f4-cca7c2094c49-image.png]

    @Adrian-Hidalgo Correct, this is on an m500 drone. I intend to fly to GPS waypoints in mission mode (I have done this a few times successfully before noticing the local_position_ned was drifting). I didn't see the vehicle drift while in flight but wanted to double-check before flying again. I am not sure when the local_position_ned began drifting. I have tried resetting qvio - seeing that doing so had resolved local_position_ned issues for someone on another forum. I have the drone on my desk and powered from a 12V 3A wall power supply - I believe that is why the battery status reports zero (when I use a lipo, the battery status looks correct). & yes the vehicle parameters have been loaded.

    Hi, we only support ModalAI products on this forum. Have you seen the PX4 support forum and Slack? That might be a better place to start: https://docs.px4.io/main/en/contribute/support.html

    @Dong-Liu Unfortunately that is a bug with the SD865 SOM. We've had a ticket open with Qualcomm for a long time with no solution yet. Checkout this thread for a solution: https://forum.modalai.com/topic/794/how-to-set-up-a-static-ip-in-rb5/15?_=1659465332297 You basically just need to create a systemd service file to set the IP on boot.

    @Chad-Sweet yes I have! In fact, I'm quite certain that it has been configured properly and the vibration levels are manageable. As I have said, my flights are predominantly indoors and the drone performs fantastically in an apartment/cluttered environment. But i noticed that it drifts in almost all 3 axis when travelling down an empty hallway/corridor and the feature points tracked by QVIO seems to be further down at the end of the hallway (more than 20-30m away)

    We have never used the Flir Vue camera. The only experiments we have done with aux pwms is documented here. Hopefully that helps.
