Is there any explanation how to work with VLYNQ Interface block in MATLAB 2008a, that came in board support package?
By the way do you have any new knowledge about my previous messages?

The DaVinci processor (VLYNQ Interface) block in MATLAB has integrated HTML documentation.
Double-click on the block to access it's parameters, then press on the Help button to access this documentation.

Thank you it helped a little, but I wish there was more information.
Any way I tried to recreate algorithm based on led_demo:
I did model in simulink and complimented to CCStudio project, that takes status of DSP SW10, turning DSP leds accordingly and sending this status to FPGA by block "VLYNQ REG write". This block calculates register address by command "vlynq_mmap.led".
Beside that I did model in simulink and generated ISE project by system generator, that receive status register and turning FPGA leds accordingly. This model contained "VLYNQ Interface",which mapping memory for register and make M5 (DSP reset) be high.
First of all I checked if DSP and FPGA leds working without VLYNQ, and they worked perfectly.
But when I tried to compliment it with VLYNQ it didn't work.
First of all when I run DSP part of the project I see leds swiching one after other in the cycle. And when I am trying to compile ISE project I get message that ISE cannot locate source file "Name of the project_cw.bmm".
I tried to show it location in "sysgen"directory, that placed in project directory, but then when compiling I get the following error: NgdBuild:989-Failed to process BMM information "Name of the project_cw.bmm".
I tried not to show it location also, then it success to compile but still don't work.
All usual Jumpers are in defaults positions,
JP7 open, JP14 closed, JP9 M0|M2.
So I guess my problem is in "Name of the project_cw.bmm". So what should I do? (Sorry for so long question )

This may take a long to diagnose using dialog on forum ...
Can you archive the ISE project (into a ZIP file) and put it on our FTP server (http://xfer.avnet.com/).
I will look at the project and try to find the problem ...
