Simulink support for Arduino Duemilanove

HI,

I tried building a code from simulink model and then downloading the code generated using simulink support package for the Arduino into the Duemilanove board.

I got the following errors:

/**1. The call to arduino_make_rtw_hook, during the after_make hook generated the following error:
Could not open file .\DECU_modified.hex. No such file or directory.

  1. Could not open file .\DECU_modified.hex. No such file or directory.

The build process will terminate as a result.**/

The build process was succesful for the demo model that was given as example with the simulink support package.

Please help me if anyone is aware of this problem.

Thnq,
Chiru
