Hi Boaz,

Try removing the code in the Desc box . .  I recall that there were some additional checks on content made recently, and some code postings are not accepted.  Just a guess on my part, but let's see - you can post the code in a .txt document.

Okay. Look like this forum is not different. I cannot post my problem reply. The reply consists of text and code. Here's the text.

You have allocated 0x800 or 2kB bytes for stack but the image_array of 256kB is declared on the stack. Also, SHRAM is only 128kB in size. The compiler cannot detect stack overrun due to large local variables.

You should move image_array off the stack. Make it a global rather than local variable. The compiler can check global memory usage.

To reduce memory usage, you can reduce image_array to an array of bytes instead of 4-byte "int". First read it in as a 4-byte int, then convert it to a byte.

You should check to see if the file opened successfully. You may be using fscanf with a null FILE handle.

Try attaching the code as a text file.

#include <stdio.h>

unsigned char image_array[256*256]; // 256*256 = 64kB

int main()
{
  int i;
  int a;
  FILE *image;
  image = fopen("image_cameraman_tiff.txt","r");
  if(image == NULL)
  {
    printf("Open failed\n");
    return;
  }

  for(i=0;i<5;i++)
  {
    fscanf(image, "%d", &a);
    image_array[i] = (unsigned char)a;
  }
}

#include <stdio.h>

unsigned char image_array[256*256]; // 256*256 = 64kB

int main()
{
  int i;
  int a;
  FILE *image;
  image = fopen("image_cameraman_tiff.txt","r");
  if(image == NULL)
  {
    printf("Open failed\n");
    return;
  }

  for(i=0;i<5;i++)
  {
    fscanf(image, "%d", &a);
    image_array[i] = (unsigned char)a;
  }
}

Test using rich text editor.

In the quick reply window, I just pasted both text and response into the window. I pre-typed my reply in Windows notepad. Pressed "Reply"

In the rich text window, I pasted in my text first. Then clicked on the Syntaxhighlighter "</" and pasted my code in the code window. Closed code window. Everything looks okay in the rich text window. Press "Post".

That was me impersonating your account and posting from inside TI's network as a test.
