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?
