I have recently been trying to simulate a hardware environment on the Cube Orange Plus. I am using PX4 1.14 on it and I was having issues running HITL on it that matches the issues posted here: [Bug] HITL simulation motors not spinning PX4 v1.14.0 · Issue #22625 · PX4/PX4-Autopilot · GitHub
As an alternative, I was considering running SIH on the Cube Orange Plus. However, when putting the vehicle into SIH mode, it was not showing on the map on QGC and arming / taking off was not working. I figured out it was because CONFIG_MODULES_SIMULATION_SIMULATOR_SIH=y was not included on the default.px4board for cubepilot_cubeorangeplus.
I was thinking it was quite odd that other boards had SIH support but the Cube Orange Plus did not, so I did some investigating. I found with the regular Cube Orange, it did have SIH, but it was removed to save flash memory.

I added the argument back on Cube Orange Plus and SIH worked for me, but I was curious if it is a bad idea to have SIH enabled on the cube orange plus. I am not very familiar with the low level architecture of it. Does SIH waste enough flash memory where it would be a problem to have on it?
