Thanks for the prompt reply!
It was indeed a hardware problem. The calibration resistor was missing.
Best regards,

No, not that I remember.

The only idea I have is power supply. Are you using an ATX power supply? This
is mandatory for PCIe IIRC. Other than this I have never heard of a board
hanging in PCIe init without any card installed. Perhaps it's a HW problem on
the board.
BTW: Did you test with an earlier U-Boot version? How did this work?
Best regards,
Stefan
