I'm also using the switches and LEDs on my board through memory mapped PIOs and these seem to work (I can set the LEDs and read from the switches using code running on the NIOS). I did not do any sort of auto generation of a BSP project. Not sure how to do that or whether I would need to for such a simple test.
