You have created a project that uses the multi-core, one application per core programming model for the ADSP-21573 processor. In this approach, each core is treated as a separate processor, and each project is built individually. Effectively, multiple single-core applications are built independently, and run in parallel on the processor. The shared memory areas, both internal and external, are left to the developer to arrange for shared, serializable access from each of the cores.
If you selected the 'Add template code to the application' option in the Project Wizard, your project will contain template code to help you get started, including a 'main' function for all the cores. If you did not select the option, you will need to declare your own 'main' functions. A 'main' function must be declared for all the cores.
To get started with your application, begin adding your source code to the 'main' function in all the projects. If you are defining your own, you must include a call to the adi_core_enable function in your core 1 project. This function allows core 1 to enable core 2, and is declared in adi_core.h. If you selected the 'Add template code to the application' option this function call is automatically added to your 'main' functions in each project.
