The up two topics are the same questions. I have change my code follow up two topics,and XFP loopback is OK!
However, when I communicate with Intel X520-DA2 10G Adapter, Windows show Adapter is not connected. I pretty sure X520 Adapter work good .
I think there is no Auto-negotiation between them.
The both threads you mentioned discuss an XFI connection without a PHY. Based
on the picture you attached, you have a PHY in between. That PHY is responsible
for autonegotiation with the far end.
Suggestions:
1. Declare your PHY in the Device Tree as specified in the bindings specification.
See LS1046A-RDB DTS to get an example of a 10G PHY connected to an mEMAC.
2. Most Ethernet PHYs require a driver. Contact the PHY manufacturer for drivers,
required Device Tree node properties and troubleshooting recommendations.
