Description
Yes, you can reset a Nios II processor within your software application by using a function pointer set to the reset address of your processor. A software reset is illustrated in the code segment shown below:
#include <stdio.h>
#include "system.h"
#include "nios2.h"
#define HAL_PLATFORM_RESET()
NIOS2_WRITE_STATUS(0);
NIOS2_WRITE_IENABLE(0);
((void (*) (void)) NIOS2_RESET_ADDR) ()
int main()
{
printf("Hello from Nios II!\n");
HAL_PLATFORM_RESET();
return 0;
}
The HAL_PLATFORM_RESET macro disables interrupts and then calls a pointer to a function set to the reset address. This causes the processor to jump to the hardware reset address.
