Hi,

This looks to be an error in assembly code. There is an advisory in the errata (SPRZ357K) that explains what this error is about: "FPU: FPU Register Write Followed by F32TOUI32, FRACF32, UI16TOF32, or F32TOUI32".

Do you know what revision of the silicon you are using? You can determine silicon revision in the manner described in section 3 "Device Markings" in the same errata. Are you writing this code yourself or is MATLAB generating it? If MATLAB is generating the code is there a way you can figure out which codegen version its using?

thank you for your answer
the code is generating using Matlab/Simulink

Ok, do you know the C2000 compiler version MATLAB code generation tools use?

Did you try the basic example model that is included in the Embedded Coder Support Package for Texas Instruments C2000 F28M3x Concerto Processors? Does that work?

Here's the Getting Started doc link (login might be required) which includes info on the models and how to get things configured:
