Simulink Support Package For Arduino Hardware Issue, CAN Receive Block

Hello,

I am learning to program Arduino on Simulink. I am currently following the tutorial "Transmit and Receive Data Using Arduino CAN Blocks" on Mathworks when I received this error of exceeding memory. I am using R2024B version. The board I use is Arduino Uno R3.

So far I have tried:

- Changing Hardware Module to another board, upload to receive fail message then change back to Uno and upload.

- Run in I/O mode instead of on-board.

Neither of these worked and I still get the same error message.

What should I do next? Could this be a Simulink-related issue? Any help would be greatly appreciated.

Thank you.

I recommend to check this page:

Hello Jährig, thank you for the response. I checked the page you mentioned and the "Build Configuration" in my example model.

In the example model, the parameter is set to "Faster Runs" by default. I have also tried changing it to other options then back to "Faster Runs" to see if it would change anything. Unfortunately Simulink still gave the same error message.
