Hello @C_Zuercher_APR ,
The problem is caused by the Fuzzy block which inserts the variable declaration code inside our step function. The variables' sizes are so large that it causes a stack overflow.
There are two ways of solving this.
1. One of them is to try forcing the block to declare the variables from lines 310 to 323 as global so as they do not end up on the stack, on each step function execution. I've tried that but I was not successful so you should consider contacting MathWorks Support. I am sure that they can help you with this.
2. You can use a custom linker file that contains an increased stack size. This is the faster workaround for your scenario. I have attached the linker file with a higher stack size.
Let me show you how to install and use this linker file.
a. in Matlab, type the following command:
cd(fullfile(mbd_find_mpc_root, '\mbdtbx_mpc574x\src\linker\gcc'))
This will change the directory to where the linker files are stored. In this folder, you should copy the attached MPC5744P_flash_IncStack.ld file.
b. In your model, Open the main config block. Go to "Build Toolchain", uncheck the "Default linker..." and select the newly added file.
If the added linker is not displayed there, just replace the 'MPC5744P_flash.ld' with the one attached.
Hope this helps,
Marius
