Matlab 2022 Arduino Simulink Exceeding Memory Error

Hi,
I've done Simulink on Arduino with Matlab 2019b with success.
However, super annoyingly, Simulink Support Package For Arduino Hardware does not include much on Matlab 2019b. So I installed Matlab 2022 + needed add-ons and got way more features to aid my programming. Great!
Now, I suddenly get this error, even with a tiny program to make Digital Output 13 ( onboard LED) to blink with a impulse generator.
ERROR:
Top model targets built: Model Action Rebuild Reason ==================================================================== untitled Failed Code generation information file does not exist. 0 of 1 models built (0 models already up to date) Build duration: 0h 0m 11.414s
The following error occurred during deployment to your hardware board: The generated code exceeds the available memory on the processor. It uses 134.2% of available program memory and 48.6% of available Data memory.
This doesnt make any sense. I then go back to my Matlab 2019b and make the same program without problems. So I would assume the problem is with Matlab 2022 version.
I've googled the error, but people are just saying "your program is taking to much space, try to make it smaller", which I dont think is the correct solution in my case.
Any ideas?
Hardware: Arduino Uno
COM : Automatically
Baudrate: 115200 ( Default)

Hola, lograste solucionarlo?
Just installed 2022a for an arduino project and am running into whole bunch of issues. 2022a does not even allow me to set hardware configuration in the simulink. I then installed 2021b and it does nothing on arduino (same blinks program). With 2020b however the Arduino Due board works just fine.
It's a shame Mathworks released these hardware support packages without testing them with the new matlab versions.
could you resolve the issue. I am facing the same with arduino mega 2560? Thanks
Disclaimer: I am completely new to simulink
I experienced the same issue while trying to "Run on the hardware" with "Monitor and Tune". When trying "Build, Start and Deploy" the build worked as expected. My assumption is that the code needed to monitor and tune is much to large for the UNO. Again, i am new to all of this and would love a proper explanation.

Hello,
This may be a few years late but I recently face the same problem with version 2023. The teaching assistant for my unit found out that if you go to hardware settings -> change the board to Arduino Mega (any version) -> try to run it -> let it fail -> then change the board settings back to Arduino Uno it will work.
I tried it and it worked for me. I dont know why this works, I dont know how she figured this out, Im just confused.
Regards.

Thank you! This worked for me as well.
Thank you for existing. You saved me after two days of cursing.
You also just saved me after hours of headache and confusion. I would have never thought to do that!
You are a G, thank your TA for me
Thanks! This worked for me as well.
Thanks, worked for me!
