With GDB works fine, but I want to write a script in RedBoot that will be
executed at boot time and then which executes my program. The program that I
have executed with GDB is one as follow:

/* this is a simple hello world program */
// led_blink.c
#include <stdio.h>

extern void set_leds(int val);

int main(void)
{
  int i=0;
  while(1)
  {
    set_leds(0x04);//red LED
    for(i=1;i<100000;i++);
    set_leds(0x02);//green LED
    for(i=1;i<100000;i++);
  }

  return 0;
}

// end of led_blink.c

This program runs fine with GDB but not with "go"  command within RedBoot.

So, I don't  know what is the error.

Thanks !
