After all the core projects have been created, configure and build the secure CM33 project first and then the non-secure CM33 project. The CM33 project contains a non-secure-callable file, and it must be built before the non-secure CM33 project. There is nothing to configure for the CM55 core.

The project creation process creates and adds postbuild commands automatically. For the secure CM33 project, the postbuild command will sign and shift the hex file. For the non-secure CM33 project, the postbuild command will shift the hex file. For each project, the postbuild command will also generate a combined file if all projects have been built at least once.
