hi,
I'm working on the simulator c54x(ccs v2). In my c code i'm inputing
two *.dat files through probe points and also taking the output in
two *.dat files . I'v converted the wav file to dat file through c
code and store them in teh project folder and included the ccs header
into the dat files. when i'm
running code, i get this message

open error: Invalid file ID (32768)in CIO message!

The code for the programm is #include <stdio.h>
#include <stdlib.h>

#define NO_OF_TAPS 700
#define STEP_SIZE 0.09
#define BUFFSIZE 300

int input1[BUFFSIZE];
int input2[BUFFSIZE];
int output1[BUFFSIZE];
int output2[BUFFSIZE];
float mue=STEP_SIZE;
int M=NO_OF_TAPS;

static void dataIO();
static void lms_algorithm();

void main()
{
FILE *fp;
fp=fopen("base.dat","rb");

while(!feof(fp))
{
dataIO(); /* here i'm putting probe point */

lms_algorithm();
}
}

static void dataIO()
{
/* do data IO */
return;
}

static void lms_algorithm()
{
int size=BUFFSIZE;
int i,j;
float W[300]={0.0};

while(size--)
{
for(i=0;i<M;i++)
output1[size] = output1[size] + W[size]*input1
[size-i];

output2[size]=input2[size]-output2[size];

for(j=0;j<M;j++)
W[size]=mue*input1[size]*output2[size];
}
return;
}
How anyody help me in this regurd.

just give us the dat file.
There may be something wrong in that file.
