Hi,
We have 4 I210 connected on C5 through the bridge. But we are able to see only 2 out of that on lspci.
I210 connected on Lane 6 and 7 are detected whereas I210 connected on Lane 2 and 4 are not detected.
We also followed the debug steps for PCIe Link-up failure which is mentioned in the document “JetsonModuleAdaptationAndBringUp”. But still facing the same issue.
Attached the log of “sudo lspci -vvv” and “sudo dmesg | grep pcie”
