Hi CAlex,


I think I misunderstood that you are using interrupt previuosly from another case.

You are using HPS polling method to detected the changes in the PIO IP?

If you are using polling method, how fast that it tries to read the changes?

And you are not running baremetal application right?

    Yes you are right, there is no delay between polling,

    and yes it is run on the linux.
