CCS/TMDX5535EZDSP: Problem with TIesr Demo

Part Number: TMDX5535EZDSP

Tool/software: Code Composer Studio

Hello,

This is my first time working with DSP's and I need to implement a voice recognition software for a system i'm working on. I bought the eZdsp 5535 to do this task and the TIesr engine, now I'm trying to do the Tiesr Voice Trigger Demonstration but i'm facing some problems:

Q1:

- The guide talk about importing projects to the workspace:  TIesrDemoC55 and TIesrEngine.

But I only found  the TIesrEngineC55 folder and the TIesrDemoC55 doesn't seems to be anywhere inside the TIesr_src folder.

Then:

There isn't a TIesrDemo here or anywhere else :(

Q2: 

I don't know if the OLED stopped working because at the beginning it appeared '' Play audio from the PC '' and after doing some other demo projects, when connected by micro USB (J1), I can't record anything or hear anything from the PC and the OLED also stop sending that message. I don't know if this is normal, I think it is but I want to be sure. (I did the test_led project to verify the usb connection and it worked, but only that demo)

Q3:

I also tried to do some other Demos, like the getting started that comes with the TMS3205505. And I could make the Target connections, debugging and running. But I couldn't manage to get audio files with the mic, maybe it is because im using a TMS3205505 demo project with a eZdsp 5535 board.

Maybe this are very simple question, but i'm having difficulties to understand and make the eZdps work,

I'd appreciate any help you could give me...
