C code generation from simulink model...

When I built the simulink model I got the folloeing error :

Error building Real-Time Workshop target for block diagram 'dspafxr'. MATLAB error message: 
Error using ==> callMakeHook.p>callMakeHook at 47 
The call to ccslink_ert_make_rtw_hook, during the entry hook 
generated the following error: 
Error using ==> i_entryHookpoint at 52 
Error while creating the link for IDE.
The build process will terminate as a result.

can someone tell me why I am getting this error please ??? I am using Matlab R2007A CCS V3.1 DSP/BIOS 4.90.

Plz sombody help me ???

Sujeet: Could you try running one of the demos for the product? You will need to browse the documentation Contents pane to find one. I suspect that there is something wrong with your CCS setup, but I don't know enough to tell what exactly.

I have followed each and every step of the webinar but still I am getting the same problem. Do you have any other idea... ??

If you have a license that is on maintenance, consider contacting MathWorks Tech Support.

Hi all: I have the same error with you and now I can run it well. R2007a + CCS3.1 + F2812 DSP Maybe steps below will help you 1.Check the connection with your DSP and emulator. 2.Open CCS setup and right click -->properties (on the device you use) then you have to choose the gel file for your DSP.(This step is very important) 3.Then open CCS3.1 and connect to the DSP. 4.Open R2007a and enter "cc=ccsdsp" in the command line. You will see: CCSDSP Object: Processor type : TMS320C28xx Processor name : TMS320C2800_0 and so on... 5.Open the model and build it.
