I think this project is really cool!
I think there’s a lot of complementarity with Stephen’s Rpanion Server project. ping @stephendade
By the way, the default OBAL RPI image could be a version of Rpanion Server… (flight controller + linux + networking management)
As @ppoirier pointed, an RT Kernel in the future would really be interesting. I would like to have more confidence that the Ardupilot code won’t lose space for scripts/programs in the OS would be interesting. If you wish, you could test some flights while running something like sysbench or geekbench.
I’ve had problems using RPi Zero as companion computers when it was some interpreted code… Today I prefer to use RPi 4 to be able to use pyhton and pymavlink at will.
I really enjoyed it, and I hope to build a unit when I have time.
