Hi Meruzhan,
The error message you're encountering indicates that the problem is with the deployment process of the MATLAB code onto the Raspberry Pi. Kindly ensure the following points as these are potential root cause of this error, such as incorrect paths, missing libraries, or configuration problems.
  1. Check File Paths: Kindly ensure that all file paths in the script are correct and accessible. The error message references paths "/home/pi/MATLAB_ws/R2024a/C/Meruzhan/Yolov3/codegen/exe/deploy_tracing_raspberry_pi". Make sure these directories exist and are writable that is having write access.
  2. Library Dependencies: The error mentions that libraries like "-lSDL", "-lmmal" and "-lmmal_core". Verify that these libraries are installed on the Raspberry Pi. You need to install these missing libraries using "apt-get".
If the issue still persists, it would be best handled with MathWorks tech support. Could you submit a technical support request?
