Codedescriptor.dmr not found

Does anyone know how I can resolve this? I am trying to do a standalone setup on my Arduino Due. This warning show up every time I build and the LED on my board stays solid. When I press reset on the board nothing changes.

### Starting build procedure for: Experiment_1_2_b

Warning: File 'codedescriptor.dmr' not found.

Warning: File 'codedescriptor.dmr' not found.

"codedescriptor.dmr" is an artifact file that is created in the "model_xxxxx_rtw" code generation folder for targets such as ert.tlc or slrealtime.tlc. The file is used by Simulink in subsequent (re-)build processes. If you are not encountering any adverse behavior, I think you can simply ignore these warnings.

You can try to remove the warning by running the following commands to reset your MATLAB path:

>> restoredefaultpath
>> rehash toolboxcache

Re-run the build. If this resolved the issue, save the new settings by executing:

>> savepath

Hope it helps!!

I just started seeing this same warning, but I'm not using Simulink Realtime, just generating to run offline on ARM platform. I tried running the commands you suggested to reset paths and toolboxes, but still no luck. Any other suggestions? Thanks!

This essentially happens when an unrelated 'codedescriptor.dmr' file is found on the search path during the model build stage. Please refer to the MATLAB Answers link below for more information:

And just to add: as Ritish mentioned, in most cases, you can usually ignore these warnings.
