Copter-4.6.0-dev: DroneCAN over MAVLink broken? #28175

Closed rmackay9 closed 2 months ago

Copter-4.6.0-dev seems to have broken something that causes MP's DroneCAN/UAV screen to be unable to communicate DroneCAN enabled devices (e.g. a Here4 GPS)

This is what MP's screen shows when Copter-4.6.0-dev (on a CubeOrange with Here4 GPS: image

This what it looks like using Copter-4.5.6. image

Problems occur with DroneCAN GUI Tool too.

Connect with mavcan over USB, autopilot shows up correctly. Screenshot 2024-09-21 111832

Switch to bus 2, all traffic disappears Screenshot 2024-09-21 111843

Switch back to bus 1, all traffic still gone Screenshot 2024-09-21 111858

This persists until you reboot the autopilot.

You can connect initially on bus 2, and get the correct traffic, but if you switch busses, it locks up until you reboot.
