Model Error Code generation file does not exist SIMULINK and ARDUINO

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

If really needed you could install https://github.com/arduino/ArduinoCore-avr

[BAPTISTE SALAUN]

Wich file, and it is compatible with simulink, thanks for your quick reply

[Walter Roberson]

https://github.com/arduino/ArduinoCore-avr/blob/master/cores/arduino/wiring_pulse.S

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.

[BAPTISTE SALAUN]

I install all the file, but I already have the same error when I want to bulid model on my arduino board.

However, it worked well two weeks ago and it always work on arduino's application

[Walter Roberson]

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

[Alex Gaina]

Baptiste, did you get it to work? I have the same problem

[BAPTISTE SALAUN]

Hello Alex, after one complete reinstallation, I never succeded to find solutions or the location of problematics files. One of my technologie teacher who actually have similars problème on severals pc at my school says that problems come from "hand made update" (I don't know how to translate well).

Actualy to use Matlab I have to change of computer for the moment.

I sincerely hope than you will found solutions.

[Alex Gaina]

Thanks Baptiste, I'll keep digging...

[ashwini]

HI Alex, Baptiste , Have you got any solution for this problem?

I am also getting same error.

[Matteo D'Onorio]

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

[Filip Poloczek]

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

[Aditya Chari]

Has anyone got the solution for the problem? I am also getting the same error

[Ernst Wierenga]

Me too. I use macOS.

On windows it works fine?

[prudhvi]

Remove all the cache file .slxc, slprj folder and rtw folders

Answer 1

[Catalin Stefan Teodorescu]

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).

[LUIS ENRIQUE CONTRERAS PALOMINO]

Catalin, after hours trying to find a solution your answer solved my problem. Thank you very much!

[Po-Yen Lin]

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

[Jeffrey Darwish]

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.

[Rodrigo]

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.

Answer 2

[Gargi Patil]

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.

[abdullah]

I have the same error, did you solve it ?

Answer 4

[Eric Hayes]

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

[Tinotenda Ashley Mwarunzika]

Did you manage to solve it?

Answer 5

[Lars]

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.
