HPI and DSP/BIOS

Started by aine_canby ●August 18, 2003
Hi everyone,

I'm trying to implement a HPI handshake between a windows app and my
c6711dsk.

I have this working without DSP/BIOS, but I can't get it to work
using DSP/BIOS.

This is my dsp code (I'm using the same code for both non-DSP/BIOS
and DSP/BIOS) -

#define ID_0 0x12345678
#define ID_1 0xf1f2f3f4
#define ID_2 0x08070605

#pragma DATA_SECTION(handShakingBuffer, "my_DataSect")
int handShakingBuffer[HS_BUFFER_LEN];

/*
* ======== main ========
*/
void main()
{

handShakingBuffer[0] = ID_0;
handShakingBuffer[1] = ID_1;
handShakingBuffer[2] = ID_2;
handShakingBuffer[3] = 0;
handShakingBuffer[4] = 0;

return;
}

Actually, the DSP/BIOS version also includes -

#include "audiocfg.h"
#include "audio.h"

My windows app loads the dsp program to the dsp board, and polls
until the following are set -

handShakingBuffer[0] = ID_0;
handShakingBuffer[1] = ID_1;
handShakingBuffer[2] = ID_2;

My windows app looks something like the following -

sBoardFile = "F:\\ti\\c6000\\dsk6x11\\doc\\ti_ppdsk.cfg";

pBoardFile = fopen( sBoardFile, "r" );
fclose(pBoardFile); dsk6x_open(sBoardFile,&hBd) )
dsk6x_reset_dsp(hBd,0,1) )
dsk6x_hpi_open(hBd))
dsk6x_coff_load(hBd,coffNam,bVerbose,bClr,bDump))
dsk6x_hpi_generate_int(hBd))

do
{
readLength = HS_BUFFER_LEN*4; /* 4 bytes for 1 word */
/*----------------------------
---*/
/* Test if handShakingBuffer actually read
(completely) */
/*----------------------------
---*/

if (!dsk6x_hpi_read(hBd, handShakingBuffer, &readLength,
DSPHS_BUFFER_ADDRESS) || readLength != HS_BUFFER_LEN*4)
{ /* evm6x_hpi_read() failed */
continue; // try again
}

/*----------------------------
---*/
/* Test if handShakingBuffer contains correct
ID */
/*----------------------------
---*/

handShakingFlag = 0; // reset hand shaking flag
if(handShakingBuffer[0] != ID_0)
handShakingFlag = 1;
if(handShakingBuffer[1] != ID_1)
handShakingFlag = 1;
if(handShakingBuffer[2] != ID_2)
handShakingFlag = 1;
} while (handShakingFlag == 1);

The DSP/BIOS version is getting trapped in the while loop, because
the dsp is obviously not setting the handShakingBuffer, or the app is
not reading this buffer correctly. THe non DSP bios version does not
get trapped.

My non-DSP bios project also includes a vector.asm file -

} My DSP/BIOS project contains a cdb file, and a cmd file. The cdb file
is not set up to do anything other that to define the chip - c6711
etc. Is there anything else I should be setting up in the DSP/BIOS
version?

Thanks,

Aine.

This is my cmd file for the DSP/BIOS version, in case it gives any
clues. Thanks.

One obvious problem is your INT13 vector below has only NOPs -- which means your
dsk6x_hpi_generate_int() call is wishful thinking. Another possibility is that
DSPINT is not enabled in the IER register.

Try reconfiguring DSP/BIOS or patching in some code somewhere that enables
INT13.
