In Nios program.

Say you have a spare PIO port named led_out, possibly connected to LEDs.

Then you can toggle the first pin by calling periodically this function: 

# include "altera_avalon_pio_regs.h"
 
void PIO_pin_toggle(void)
{
   alt_u8 pio;
   pio = IORD_ALTERA_AVALON_PIO_DATA(LED_OUT_BASE);
   IOWR_ALTERA_AVALON_PIO_DATA(LED_OUT_BASE, pio ^ 1);
}

This way you can easily monitor if your Nios program starts, keep running or hangs at some time.
