I was trying to get a reverse tri copter VTOL plane (as in this link https://discuss.ardupilot.org/t/reverse-tricopter-vtol-plane/39829/71) working using the NAVIO2.
As the code to support this motor mixing is not in v 4.0.0-stable I tried to get the precompiled 4.1.0-dev from here https://firmware.ardupilot.org/Plane/latest/navio2/.
Before starting this exercise I have updated the Raspian image to the latest Buster image provided by Emlid.
Then following the instructions given here -> Navio2 Arducopter upgrade, I updated the binary.
Then running sudo emlidtool ardupilot, I can see that the Arduplane program starts up as per Emlidtool (see screenshot) - however note that the version is displayed as 4.0 instead of 4.1
During this process of start up I was expecting to see the calibration light switch between red and blue (which works when I use the build supplied by Emlid as part of the Raspian image) but this did not happen. Also once the startup is complete the green light flicks on and off. This also is not happening with the pre-built binary.
But upon connecting to Mission Planner I can see that the version has been updated to 4.1.0 Dev.
I also tried to go back to the prebuild binary 4.0.0 - stable and tried to run that. Now this is the same version shipped with Emlid’s Raspian OS. However this also did not turn the light on during calibration and startup.
Is there something I am missing?
Any help would be appreciated.
