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?Link Copied
What error messages are you receiving?
I am not getting any error message.The program hangs up after i hit the run.
You can view this great video on Youtube.
https://www.youtube.com/watch?v=hqde3xkwykkDid you re-generate BSP? and re-compile software codes (elf)?
What does the PIO connected to? Did you enable interrupt for the PIO?For more complete information about compiler optimizations, see our Optimization Notice.
