Building simulink model on Arduino Mega 2560

16 views (last 30 days)
Hello,
I've been trying to get my Simulink model onto the Arduino Mega 2560 for some time now. Unfortunately, I always get an error message. After I was able to solve some error messages, there is this error message which is just not solvable for me:

Is it possible, that the space in the path:
C:\Program Files\MATLAB\R2021a\rtw\c\ert\ert.tlc
(Space in Program Files)
results in a problem?

It shouldn't be a problem. However, you can try changing the location to one where there are no spaces in the path, and then try to compile the model.

Hi Filip Poloczek,
It seems like there is an error during the build process of your Simulink model for the Arduino Mega 2560 target. From the log, we can see that 'gmake' has encountered an error while compiling Real_Model.c. This typically indicates a syntax error. I would suggest you to review the model for any unsupported blocks. Try the following example to make sure everything was set correctly, https://www.mathworks.com/help/supportpkg/arduino/ref/getting-started-with-arduino-hardware.html
In addition, try the below general troubleshooting steps,
  1. Ensure that your Simulink model is configured correctly for the Arduino Mega 2560 target. Check the target settings, including hardware configuration, compiler options, and other relevant settings.
  2. Make sure you are using the latest version of MATLAB and the support packages for Arduino. Updates often include bug fixes and improvements that could resolve the issue you're encountering.
  3. Finally, examine the generated C code (Real_Model.c and other related files) to identify any errors or inconsistencies.
Hope this is helpful.
