Pixhawk 6X - Flash overflow PX4 v 1.12.3 - MATLAB support package

Hey y’all,

I’ve encountered a problem with the flash size using the MATLAB support package and the Pixhawk 6X with PX4 version 1.12.3

I can confirm that the PX4 Matlab Support Package generally works with the Pixhawk 6X hardware board.

However, when trying out simple test scripts (like the Getting Started uORB example), we run into a flash overflow error when trying to flash. The flash size for the standard

The flash size of the standard PX4 build is already 99% of the available flash size:

We have tried to edit the CMakefile (to exclude certain sensors etc.) like detailed here, yet ran into problems, because of dependencies in the code.
I would greatly appreaciate any help!
