In Run in Kernel mode or Priority mode, you must first create an executable target application. The Simulink^® Coder™ code generation software creates C code from your Simulink model. The bundled C compiler compiles and links that C code into a real-time application.

This procedure uses the model sldrtex_model. To open this model, in the MATLAB^® Command Window, type:

openExample('sldrtex_model')

It assumes that you have already loaded that model.

1. In the Simulink Editor, from the Apps tab, click Desktop Real-Time.

   This operation selects configuration parameters for use by the Simulink Coder code generation software. See Set Run in Kernel Mode or Priority Mode Code Generation Parameters.

2. On the Desktop Real-Time tab, click Run in Real Time.

• The Simulink Coder code generation software creates the C code source files sldrtex_model.c and sldrtex_model.h.

• The build process creates the makefile sldrtex_model.mk from the template makefile sldrt.tmf.

• The build process creates the real-time application by using sldrtex_model.mk. On Windows^®, the build process creates the binary file sldrtex_model.rxw64. On macOS, the build process creates the binary file sldrtex_model.rxm64.

  The binary file sldrtex_model.rx*64 is referred to as a real-time application. You can run the real-time application with the Simulink Desktop Real-Time™ kernel.

After you create a real-time application, you can exit MATLAB, and restart MATLAB again, and connect and run the executable without rebuilding your code. For more information, see Execute Real-Time Application in Run in Kernel Mode or Priority Mode by Using Step by Step Commands.
