I wanted to let everyone know that a PCIe PIO design has been posted for the PicoZed 7015.
It can be found here:
Search "PCIe PIO Demo"
It is called a Demo, however does include the Zynq source files and instructions on how to generate this. The reason it is a demo, there is a software driver / Windows application. The source for this has to be requested from your local Avnet / Silica FAE and it is NOT included.
