the PIO Demo design that you can download was created in Vivado 14-4.
We have built this design and it works on the PicoZed FMC v1 board using the demo GUI and windows driver provided.
We then upgraded the tools version to 15.4 and followed the same build procedure. The design builds but we see no signs of life when plugged into our test PC.
The GUI does not recognize that there is a PCIe EP on the bus.
Has anyone come across this issue?
Is there a known issue/fix?
