int yy;
t1struct xyz;
boolean v;
};
typedef struct six sixstruct;

void datacopy(t1struct *T)
{
T->y =1;
}
void start(sixstruct *data)
{
datacopy(&(data->xyz));

Hi Saida

one can look at map file to find correct "main" address and run from

that address. More hints can be found on:

thank you for your reply

i am using startup.s file which i found in ds5 archieves

i am running so many applications from same memory address

my scatter file address is 0x20000000

while debugging

i am observed that when calling this routine datacopy(&(data->xyz));

then it is aborted

if i comment all this kind of function calling then it is working

i have done small test also

just used this test code

struct rt

{ int x;

float y;

}

typedef struct rt rtstruct;

rtstruct *ptr

if i call ptr->x

then also it is aborting

it is somthing pointer and structure formation problem

it is giving memory aborts

if possible can you try in ds5 and run it

from this community i have learned more and solved few issues also

i hope i can solve this problem with all your help

i thank all the people who are supported me

regards
