Simulink generator ROS node code generation failed

Hi folks,

I'm trying to deploy the ros node usnig one of the model in my Simulink project.

I tried simple testing subscripter and publisher model and they deployed perfectly onto my Raspberry Pi.

However, when I tried to deploy my other larger model, I got the following error message:

% code generation assertion 'false' failed in 'B:\matlab\src\simulink\sl_engin\rtwgen.cpp:3286'

Has anyone encountered this problem before or have any solutions?

Thanks!

Hi Jagadeesh,

Thanks for the prompt response! I'm using MATLAB 2022B.

However, I'm very sorry that I can't share the Simulink project, which is the intellect property of my company.

The above mentioned error happens when I tried to build/run the Simulink project as a ros node on my Raspberry Pi, to which my Simulink connect.

Sincerely,

Haowen

Hi Haowen,

Are you using the Prerelease version of 2022b ?

I can understand the company restrictions on intellect property. You can reach us through the MathWorks Technical Support Team.

You should atleast send us the complete error log. Try to reduce the model to representative of your actual model to reproduce the issue. Otherwise it is hard for us to help with you the error that you are seeing.

Thanks,

Jagadeesh K.

I had a similar error. This problem was worked around by changed parameter "CodeInterfacePackaging" from "C++ class" to "Reusable function".
