PROC_load return 0x800b

Hi 

   In dmai(DVSDK 4.03), after run:

/* Load the executable on the DSP */
status = PROC_load (processorId, dspExecutable, 0, NULL);
if (DSP_FAILED (status)) {
printf ("PROC_load () failed. Status = [0x%x]\n",
(Uint16)status) ;
retVal = -1;
goto DSPmsgqClose;
}

 I got error, PROC_load  return 0x800b!  It means DSP_EINVALIDARG!

  What's problem about this?

 Does it need open DSP when system start?

  Thanks very much!
