Hello
As part of our bring-up affort on ls1028
we connected our custom fpga via pcie to M.2 connector (lane C/2 - j16)
Relavant uboot log:

PCIe1: pcie@3500000 Root Complex: no link
My questions are:
Do I need to enable any pcie related power settings?
Is led D14 should be ON (after uboot or after Linux boot):
from documentation:
led D14 should be ON when the M.2 card on J16 is powered properly and its transmitter is ready to transmit ;
currently it is OFF
Should I be able to see pcie card presence via STAT_PRES2 register ?
Thank You
