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

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).

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.

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.
