PIO problem

Question

hai,

I am using nios ii .I generated the components using Qsys and works fine.But when i add a single PIO to the existing Qsys whole thing gets collapsed.

What can be the reason for this?

I am not able to work with the code once i add this PIO?

Did you re-generate BSP? and re-compile software codes (elf)? What does the PIO connected to? Did you enable interrupt for the PIO?
