When I built the code use grt. It caused error:
Internal error while creating code interface description file: codeInfo.mat. Aborting code generation.
Caused by:
  • Time object cannot be empty
How can I solve the problem and what the reason?

I have the same problem. Is there a solution yet? It is not an issue of having duplicate codeInfo.mat files as stated in the answers.

First verify that there are no duplicate "coderInfo.mat" files on the MATLAB path by entering the command
>> which codeInfo.mat -all
If there are more than one instances of this file, remove the one unrelated to the project from the path and try code generation again.

The same problem occured for me, when I was compiling Simulink Models into C code using Embedded Coder. Since I was varying the subsystems I used Embedded Coder for, each time a new subfoulder was created in my current directory (name: "subsystemname_rtw"). They all contained a "codeInfo.mat". After I deleated the created folders, the error disappeared.
I assume that
>> which codeInfo.mat -all
and deleting all leftovers is a more elegant way, but the command just gave me an error. That's why I didn't know where to look for "codeInfo.mat"

Hi all. We have the same issue also without others codeInfo.mat in the Matlab. We are building a model for real-time target. Did someone find out a definitive resolution to this problem?
Thanks in advance
