Model Error Code generation file does not exist SIMULINK and ARDUINO
Show older comments
Deer all programmer,
Since last week, I can not continue my experience on simulink, du to an file error I suppose when I try to run any files on my arduino ardware (I use arduino uno and mega)
I try to re-upload Matlab and Simulink or create new files but failure perist.
thanks to your support
Baptiste

However, if you are missing that file, chances are that you are missing others.
Yes, it is compatible with Simulink. All of the arduino details are loaded in directly from Arduino-supplied code.

The cores directory would have to be installed to /Users/baptistesalaun/Documents/MATLAB/SupportPackages/R2020b/3P.instrset/arduinoide.instrset/Arduino.app/Contents/Java/hardware/arduino/avr/cores

Same error on macOS, instead on windows the same script works.

I get the same error and tried already the answer of Catalin Stefan Teodorescu, but I didn't work.

Hi, I got the same error an the problem was caused by a space in the folder location (e.g. C:\Users\stefa\New Folder\test, please note the space as in "New Folder"). Another thing you might want to try is to change the path to something short, as close to C: as possible (e.g. C:\test).

Hi, what file is this exactly? I have the same problem but I dont know which file I should move.

I beliueve they mean to create a folder in the C drive and call it Test. That way you have a VERY short path for simulink to go to.

Hi, the advice helped me. What I did was: I again made my blink with pin 13, in a new Simulink model and when I saved it I changed the folder path to c:\proyectosSIMULINK, I created the folder proyectosSIMULINK. Then I went to MATLAB and redirected the folder path where I saved my project in Simulink. I went back to Simulink and clicked built.

My understanding is that you are facing an error due to the gmake command with the error message as “No rule to make target”.
The following cases typically give rise to this error:
1. The file: `/Users/baptistesalaun/Documents/MATLAB/SupportPackages/R2020b/3P.instrset/arduinoide.instrset/Arduino.app/Contents/Java/hardware/arduino/avr/cores/arduino/wiring_pulse.S' could be missing in the given directory
Verify the existence of the file through File Explorer.
2. The above-mentioned file could also be dependent on another file that has been updated making it necessary to regenerate the file: ‘wiring_pulse.S'.
3. The project or source/include file path contains white spaces that “make” cannot handle.
4. The compiler version used during run time is not correct. Use the correct version of the compiler used originally in the project.

Simulink default hardware settings were set to the incorrect COM port for my micro controller. Hope it helps.

I finally resolved the issue by re-doing the 'Setup Hardware'.
I assume it is due to me manually moving the simulation file and messing up the file path.
