NIOSII RST pin

Dear guys, I would like to implement a reset of NIOS II processor by software. So I have included by SOPC builder a simple output PIO which is directly connected to the processor RST pin. ...

If you just want a software reset then

1. disable all IRQs (if you use any)

2. use

goto *((void**) NIOS2_RESET_ADDR);

to jump to the reset address of the NIOS.

NIOS2_RESET_ADDR is defined at system.h, so don't forget to

# include <system.h>

This will ONLY reset the CPU, NO reset for any of the peripherals !!

Hope this helps,
