Intel: Cyclone® V uses PCI-Express (PCIe) Endpoint. I would like to re-execute Link Training from the Endpoint side, but what kind of reset should I apply to the IP?

PCI Express

Category: PCI-Express
tool:-
Device: Cyclone® V


Execute pin_perst on the Endpoint side.
In addition, when reset by pin_perst is executed, information such as Configuration Register is also initialized, so it is necessary to execute Configuration Transaction again from the HOST side.
