I create QSYS system based on the Altera example QSYS project for Stratix V PCIE.
But this project is not working.


It happens that PCIE LTSSM = 0x00 (DETECT.Quiet).
Or is that PCIE LTSSM = 0x01 (DETECT.Active).
Or is that PCIE LTSSM = 0x00 -> 0x01 -> 0x00 -> 0x01 -> 0x00 ... .
Or sometimes PCIE LTSSM = 0x0F (L0 - works fine).
Moreover, these results may give one and the same sof-file (reprogramm the same sof-file).
All constrains described and TimeQuest not report an error.


Reflex support says that their project from flash works and they will not help us.
What to do?
Any help me?
