Hello,

Just a generic question. For running PX4 on the DSP, I noticed that they typically come pre shipped on 1.14. However, I do see support for mainline in the docs. Is 1.14 still the most stable, or can I follow a process to upgrade?

Thank you,
John

Our upcoming SDK 1.8.0 will have a release 1.18 based version of PX4. The package we are testing with can be found here: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-px4_1.18.0-1.0.9-202610051650_arm64.deb. PX4 parameters are different in this release than the 1.14 based versions so that needs to be considered. Our voxl-px4-params utility has been updated for this already and will be part of SDK 1.8.0. Directly building the tip of mainline should also work although that hasn't been tested for a few months.
