[ECOS] microsec delay

[ECOS] microsec delay

[Natarajan, Mekala (CTS)]

Hi,
	i am trying out with the micro-sec delay MACRO to  get microsec
delay. This is the sample program that i am trying. But when i run this
program from gdb it gives SIGILL-illegal instruction.       


#include <cyg/kernel/kapi.h>
#include <pkgconf/redboot.h>
#include <pkgconf/hal.h>
#include <cyg/hal/hal_if.h>
#include <cyg/hal/hal_tables.h>
#include CYGHWR_MEMORY_LAYOUT_H

int main(void)
{
  int i = 2;
  int j = 0;
  int ticks;
  diag_printf("\ni=%d\n",i);
  ticks=do_ms_tick();
  diag_printf("\n ticks = %d\n",ticks);
  return 0;
}


unsigned long
do_ms_tick(void)
{
    static unsigned long ticks = 0;
    CYGACC_CALL_IF_DELAY_US(1000);   // Wait for 1ms
    return ++ticks;
}

Can someone help on this..
