Hi,
I am using a TMS320F28335 DSP with code composer V4.1.3
I am using a large array to strore an image in memory (static Uint16 [144][89]). I have modified the linker to expand the .ebss section to 16K which should be plenty large to contain this array. Relevant linker code below. I am getting no errors at compile.
RAMIMG : origin = 0x00C000, length = 0x004000 /* BB modified code */
.ebss : > RAMIMG, PAGE = 1
My question is twofold.
First I am trying the initialize the array to zero. I have tried setting a value to zero and hoping the compiler would initialize the rest. This does not work. I have also tried the following code :
static Uint16 image[144][89] = {[0...88] = 0x00};
I get the following compilation error :
Severity and Description Path Resource Location Creation Time Id
expected a field name SeniorDesign PixelCapture.c line 29
expression must have struct or union type SeniorDesign PixelCapture.c line 29
I have check the enable support for GCC extensions in the language properties section of project properties.
So since I was unable to initialize the array I tried to set all the values to zero using the following code :
//Initialize Image Array
for (i=0; i<144; i++)
{
for (j=0; j<89; j++)
{
image[i][j] = 0;
}
}
This code runs for ever when I debug on chip. If I pause there are no symbols available and I cannot see where I am in code or the values of any variables. When I step through the code I cannot find the location at which the program crashes.
I believe the problem may be with accessing indexes to far to jump. Do I need some sort of far address?
Thank You for any help,
Brett
