Failed to run led demo in external mode at the raspberry pi 4B with simulink

I have tried different 32bit bullseye raspberry OS, and different matlab version, but the issuse is still exsisted, could somebody kindly please tell me about the stable version raspberry OS and Matlab for running external mode on raspberry 4B.

matlab :2023b; 2024a;

raspberry pi os: 32-bii-bullseye-armhf_2024-10-22

In addition, it can run in matlab, but the name is wrong, I suspect that this name might lead to this error.

r=raspi('xxx.xxx.xxx.xxx','pi','raspberry')

r =

Answer 1

I think that the rapsberry pi OS might not be suitable for the matlab 23b or 24a, so I download the matlab 21b and use matlab customized raspberry OS, then all things are fine.

Answer 2

[Madheswaran]

Hello Chen,

Upon reviewing the error log, it appears that the file 'tmwtypes.h' cannot be located during the code build process. This header file is essential as it contains type definitions required by the generated code. To address this issue, you can copy the 'tmwtypes.h' file from the '<MATLAB_ROOT>/extern/include' directory into your project folder. Alternatively, placing the file in the '<MATLAB_ROOT>/simulink/include' directory can also resolve the problem.

To determine the path for '<MATLAB_ROOT>', you can execute the command 'matlabroot' within MATLAB command window: https://mathworks.com/help/matlab/ref/matlabroot.html

I hope this resolves the issue!

Thank you very much!
