Problem using gdbserver
Hi,
The set up for GDB as remote debugger (target=arm-linux, host=i386) is
successful.
The following is my sample test program "test.c"
/******************************************************/
#include <stdio.h>
int main()
{
int i;
printf("Hello World \n");
for(i=0; i<3; i++)
printf("Checking counter %d \n", i);
return 0;
}
/***************************************************/
I compiled the above program using arm-linux-gcc with -g option and kept in
the target.
These are the following snap shots while debugging this program
/********************************* TARGET*********************** *****/

I don't know why things are going wrong. Am I missing some thing?? One can
observe that "Hello World" is printed seperately on the Target. Any kind of
help is appreciated in this regard.
Thanks & Regards,
Balaram.
