McBSP problem on DSK C6713?

Started by muoi...@yahoo.com ●February 21, 2006
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

Have you checked that McBSP0 is enabled in DEVCFG register?

Hi
I've verified DEVCFG
---------
#define CHIP_6713 1
#include
#include
#include
void main()
{
MCBSP_Handle hMcbsp0;
Uint32 SampleRateGenDelay;
CHIP_Config config;
CSL_init();
CHIP_getConfig(&config);
hMcbsp0 = MCBSP_open(MCBSP_DEV0,MCBSP_OPEN_RESET);
//.....
}
-----------------------------------

The velue of config is 0x01000000. So that McBSP0 is always enable.
However, I can't open McBSP0. The MCBSP_open() always returns INV value.Mike <d...@mikeroper.net> wrote:

Can you step into MCBSP_open and see why it gets the bad handle? Looking at the CSL source the only way that you should get an invalid handle is if MCBSP_DEV0 is already open or there’s memory corruption of the device table.

Hi
Thank you very much for your advice.
My problem come from the lnk.cmd file.
I used BIOS/API configuration tool to create other lnk.cmd file and it's ok now.
