Why do I see 'Unable to determine error string' message during profiling a program that includes DSP/BIOS functionality in Embedded IDE Link CC 3.3 (R2008b)?

When I try to profile a program that includes DSP/BIOS functionality, I get the following error message at the MATLAB command prompt:

 ??? Unable to determine error string.

The following steps generate the error message:

   1. Build a DSP/BIOS model.

   2. Load and run the program on your processor.

   3. Halt the program and enter any of the following commands at the prompt:

    * profile(CCS_Obj,'tic')

    * profile(CCS_Obj,'raw')

    * profile(CCS_Obj,'report')

where CCS_Obj is the name of the IDE handle you assigned in the configuration parameters for your model.

To prevent the error message from appearing, refresh the Statistics View window in CCS before you request the profiling report. Follow these steps to refresh the window and get the profile results from running your program:

1. In MATLAB, generate code for your DSP/BIOS model.

2. Load your generated code to the processor.

3. Run the program.

4. Switch to CCS.

5. Halt the program in CCS.

6. Select DSP/BIOS > Statistics View from the menu bar in CCS. This step opens the Statistics View window.

7. In the Statistics View window, right-click and choose Refresh window from the context menu.

8. Switch to MATLAB and enter one of the following commands to access the profile report:

 profile(CCS_Obj,'tic') 

 profile(CCS_Obj,'raw') 

 profile(CCS_Obj,'report')

where CCS_Obj is the name of the IDE handle you assigned in the configuration parameters for your model.
