Can't build SIH firmware for ARKV6X

PX4 Autopilot
1

In boards/ark/fmu-v6x, I made a file called sih.px4board with only one line: CONFIG_MODULES_SIMULATION_SIMULATOR_SIH=y

But when I run make ark_fmu-v6x_sih to build the SIH firmware, I get a flash overflow error. This is strange because if I repeat this process for the Cube Orange+, the SIH firmware builds successfully.

Here’s the error:

Try with current main. If that still doesn’t fit, turn off some unused modules.

I just built current main with CONFIG_MODULES_SIMULATION_SIMULATOR_SIH=y and it barely fits.
