Hello
Thank you for checking with various versions of matlab. The version I'm using is R2022A. Embedded Coder Support Package for ARM Cortex-M Processors is installed.
However, mbd_dsc_pth.m was not running.
Also, the date data was dd-mmm-yyyy hh: mm: ss by default in my environment.
I reviewed the advice I received and the installation folder.
1. The default installation folder Add On and a space were included, so specify a folder that does not have it and reinstall. 2. Execute mbd_dsc_pth.m. 3. Corrected the date data format mmm to mm.
Even if I did these things, I got an error in the model saved before modification, but when I opened the sample model again, it became normal.

Thank you for solving the problem.
Best regards.,
