Hi Team,
With reference to changes suggested on the Ticket #994123, we were able to get both the PCIe units up and enumerated properly after multiple attempts. Very rarely it is succeeding but generally we see the below issue.
Issue is, one of the PCIe links is not coming up (logs below). As a result, none of the devices attached to that particular PCIe interface except the SOC itself is enumerated.
Can you please advise on how this issue can be resolved ?
