Hi team,

I'm working with a VOXL-based drone (VOXL m500), and PX4 seems to be completely missing from the system. Here's what I’ve observed:

🔍 Issue Summary
Running voxl-inspect-services shows no entry for voxl-px4.

PX4 command is not found (px4: command not found).

No mention of PX4 binaries or service on the system.![WhatsApp Image 2025-06-16 at 4.17.14 PM.jpeg](https://forum.modalai.com/assets/uploads/files/1750054647744-whatsapp-image-2025-06-16-at-4.17.14-pm.jpeg)

PX4 cannot run on VOXL, only on VOXL 2. On an m500 it will be running on the separate flight core board.

@Eric-Katzfey Thank you for the response. Where can I find the documentation for the same? Could you provide the link to the specific docs?

@Avishkar-Seth It's kind of scattered around in the docs. But here is the high level architecture: https://docs.modalai.com/how-to-connect-voxl-to-flight-core/

@Eric-Katzfey Thanks for that. I had to start the qvio server and mavlink servers. Also, had to connect the flight controller to qgroundcontrol using the makeshift cable. The RC connection also works fine. Wondering what are the functionalities since the product is reaching its EOL and no new upgrades would be coming in terms of autonomous applications and PX4 integration. Thanks.
