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..
