I there someone who uses the SGMII Ethernet in U-Boot? I have tried the A10 SGMII Ethernet Example with my Arria10 SoC Devkit and it only works for the Linux Kernel but not for U-Boot. Our Product containing the Arria10 SX660 is only capable of 1000Base-X SGMII Backplane Ethernet. There is no way for me to use the “standard” RGMII Ethernet with 1000-BaseT PHY.
Is there any specific driver needed ? Do you have any other idea?
