= Changing application stack size =

To change the application stack size, perform the following steps:

 1. From the Simulink model window for your application model, select the ''Simulation'' menu, then click ''Model Configuration Parameters...''
    * On earlier versions of Matlab, this will be ''Simulation -> Configuration Parameters...''
 1. Under the ''Code Generation'' tab on the left, select ''OpenECU code generation...''
    * On earlier versions of Matlab, this will be under the ''Real-Time Workshop'' tab on the left
 1. Change the stack size by entering a new number in the ''System stack size'' edit box, as shown below in the red circle.
