Build a TrustZone example application {#GUID-AD3F048E-11BB-4AA5-83AA-0064F54B30AF}

This section describes the particular steps that must be done in order to build and run a TrustZone application. The demo applications workspace files are located in this folder:

<install_dir>/boards/<board_name>/trustzone_examples/<application_name>/<core_type>/iar/<application_name>_ns/iar

<install_dir>/boards/<board_name>/trustzone_examples/<application_name>/<core_type>/iar/<application_name>_s/iar

Begin with a simple TrustZone version of the Hello World application. The TrustZone Hello World IAR workspaces are located in this folder:

<install_dir>/boards/lpcxpresso55s69/trustzone_examples/hello_world/cm33_core0/hello_world_ns/iar/hello_world_ns.eww

<install_dir>/boards/lpcxpresso55s69/trustzone_examples/hello_world/cm33_core0/hello_world_s/iar/hello_world_s.eww

<install_dir>/boards/lpcxpresso55s69/trustzone_examples/hello_world/cm33_core0/hello_world_s/iar/hello_world.eww

This project hello_world.eww contains both secure and non-secure projects in one workspace and it allows the user to easily transition from one project to another. Build both applications separately by clicking Make. It is requested to build the application for the secure project first, because the non-secure project must know the secure project, since the CMSE library is running the linker. It is not possible to finish the non-secure project linker with the secure project since CMSE library is not ready.
