This task is about DTMF signal detection using Correlation, RTDX, and FFT. Code Composer Studio was used in this process. After loading all the files including c file, cmd file etc.
But the following error message keeps recurring
Please help!

Hi Abdallah,
I think it is due to using wrong memory model in the compiler. In the Build Properties -> C6000 Compiler -> Runtime Model Options, there is a selection for "Data access model (--mem_model:data). The default may be near, and that may be incompatible with one or more of the libraries since they use the .far section. Change this to either "far" or "far_aggregate" and see if the linker works better.
Hi Abdallah,
Actually i am not sure about CCSv3.1.
I will suggest you to use CCS latest versions.
I am using CCSv5.5.
Right click on project --> Select Properties --> CCS Build --> C6000 Compiler --> Advanced Options --> Run-time Model Options
You will see a screen like this, and you can do the required changes.
