Arria 10 PCIe SRIOV IP Link Training

Hello,

The Arria 10 PCIe HIP fails link training when the machine is rebooted. The only way link training works is If the computer is powered off and then turned on. Does this have to do with reset the signaling? This makes it much more tedious for testing.

Best

    Hi,


    This is unexpected if the link training fails after reboot. Do you capture the signal tap with LTSSM and PERST for both pass and fail cases?
