CvP initialization vs update modes In Cyclone V

Thanks for the PCIe Reset suggestion. I'm not a PCIe expert, but I am concerned that holding the Reset past when the controller releases it will cause the board to not get initialized. I'm doing a prototype board, so I'll probably add a circuit to try it.

I agree that the Remote Update mode is not autonomous - it simply a normal configuration that allows you to update code via PCIe later. I've been able to download firmware for years over PCI using the asmi loader, so it's not really useful new feature. I'd have much rather had the Hard IP PCIe controller come up functioning as you'd expect from Hard IP.
