McBSP0 problem on DSK C6713?

[muoinhohn]

Hi all
I've a problem in using McBSP0 on DSKC6713 board.
My program :
---------------------------------------------
#define CHIP_6713 1
#include <stdio.h>
#include <csl.h>
#include <csl_mcbsp.h>
void main()
{
MCBSP_Handle hMcbsp0;
Uint32 SampleRateGenDelay;
CSL_init();
hMcbsp0 = MCBSP_open(MCBSP_DEV0,MCBSP_OPEN_RESET);
//.....
}
-----------------------------------
This program is on CCS 3.1.
If I use the C6713 simulation, there isn't any problem. MCBSP_open() always returns the value != INV. This is ok.
But, when I connect DSK C6713 board with CCS and run debug, I always receive the value INV returned by MCBSP_open(). This is error.

Do you have the some comments or ahvices for me?

Best regards
Muoinho
