Hi Vijay,
I seeing your ltssm is stuck at 00h which is in detect.quiet stage.
This mostly happen due to the host Can't detect far end Receiver.
I suggest to check with the Connectivity problem or Board component problem/
- Is this plug in to slot that supported gen2 ?
- do you change the BIOS setting from "auto" to "gen2"
- Please check your VCCR/VCCT , ensure that it is 1.1v

Wincent,
The board is plugged into gen4 pcie slot.
Regarding the pin assignments,
The Board reference manual recommends PCML for the serdes pins.
