Hi
I managed to build the px4 firmware, following the guide:
https://docs.modalai.com/voxl2-px4-build-guide/

But I couldn't figure out how to upload the px4 firmware to VOXL2.
I want to make changes to the firmware.

Could anyone please let me know how?

I'm using Flight Deck and have the adb connection.

Thanks

@Youngjoo-Kim It's best to use the instructions in this project: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-px4/-/tree/dev. That project has a convenience script called make_package.sh. After building the code and running that script you will get a Debian package that can be pushed to the target with adb and installed with dpkg.

@Eric-Katzfey Thanks, it works! I didn't know the last part (push the debian package and install there).
