Hi,
First of all apologies - I am a novice wrt PCIe. So please excuse if this is a very trivial question.
I am trying to use a Cavium CN6020 device as a RC. It is connected to a Xilinx device. The BAR addresses are as below.
BAR0: 8000_0000h
BAR1: 8100_0000h
BAR2: 8200_0000h
I am confused about the P2N and P2P BAR registers that have been mentioned in the manual. Should I use P2P or P2N?
