we are using Arria 10 SoC FPGA Development Kit Board. generated example design and trying to do Ethernet test (PHY Serial loopback). we are getting CRC errors

Hi,

To able to help with your issue can you provide the following:

May I know which Quartus and SoC EDS version you are using?

Which example design you are using?

Also, can you share the CRC errors you are getting?

Are you using Linux environment or baremetal etc? If possible can you share the Uboot log?
