Error while generating code for STM32F4 Discovery board

Hello,

I am trying to communicate with a STM32F4 - Discovery board to let a LED blink. The task has to be done by calling a matlab function which then calls c code. When I run the simulink model with the call to Matlab it shall generate the code for the hardware. Unfortunetely, this results in an error.

If I am correct the error tries to look for a file called matlabfoo_sfun which I do not know why.

I would appreciate your help! Thanks!

Sebastian
