Simulink compilation error: Launchpad F28069M

Hello,

i am having an issue while downloading the code to the mcu using simulink code generation. My matlab version is 2016b and i am using the embedded coder add-on for TI C2000 processors. Untill now everything has been working nicely, but now i've been getting the following compilation error when building the code.

if true
%

(((((Error cannot open source file "multiword_types.h"))))))

end

What could be causing the error? I have used the same simulink model with the mcu and compiled the code without any issues. Maybe i changed something and now it cannot find the header file "multiword_types.h". Thanks in advance!

Looks like your model is stuck in external mode configuration which happens to be a intermediate config set that is used in background when running external mode. If external mode terminates with a error then the model could be stuck in this configuration and could result in this error. Please try to switch to default config from model explorer and see if this helps.

Thanks for the quick answer! it solved my issue when setting the configuration values again from a default configuration. What could be the cause of this error, in order to avoid having the same issue again? From what i know, my simulink didn't terminate the external mode with an error. I stopped the simulation normally and when i tried to run it again i had this error.
