Hello,
I am having troubles trying to get any simple project to work when I create it with the "Target Support Package - STM32 Adapter" toolbox provided by STM for Simulink.
For example, I followed the steps described in a youtube video titled "STM32F429 DISCOVERY - SIMULINK EXAMPLE 01" to program a discovery board using Simulink, STM32cubeMX and Keil toolchain.
I just load my simulink blank model, configure the setup with my cubeMX .ioc file with the port configuration and link one input with an output, as simple as that.
The problem comes when I compile the proyect from Keil. I got this log:

The kind of errors look like there is something wrong with the automatic generation of the code.
I have been able to load succesfully some examples that I downloaded from the Keil toolchain.
I am using the latest version of the toolchain, Keil V5 and the pack for my controller is updated. (In the video a previous version of Keil is used, but it should make no difference since my controller is still fully supported).
I even reinstalled all the programs but still got the same result.
In the video I mentioned before, the user only makes sure that the port is switched to SW and also that there is a flash loader set. I also tried following the steps for known problems wich appear at the bottom of the Readme file located, in my case, in C:/MATLAB/STM32-MAT/STM32/Readme.html. But neither erasing the " Configuration" string nor completing the Define statement worked for me. In fact I always got the same log.
Any idea about where can be the problem? I followed the video step by step and the rest of settings in my computer are as default.
