Companion Computer: RPi 4B Dronekit : 2.9.2 Dronekit sitl: 3.3.0

I received this two errors:

Hi @Turbullance , you get the first error because Dronekit-SITL doesn't support ARM builds (like Raspberry Pi).

Here's the link on the subject: https://dronekit-python.readthedocs.io/en/latest/develop/sitl_setup.html

You can make it work by passing in a binary and set of parameters to use. The binaries can be downloaded from firmware.ardupilot.org or compiled from source.

My PR here: https://github.com/dronekit/dronekit-sitl/pull/145 was attempting to allow automated download using ArduPilot's manifest files, but you might notice I haven't looked at it in some time.

Yeah, sure. It can be tried. It could probably work. But 100% I'm not sure.

I had the same problem 3-4 months ago. I ran the SITL on a normal laptop to test the codes I wrote. Obviously, if you don't have to, you'd better use normal laptop instead of Raspberry Pi.
