    Hello,

    may I know if this is a development kit? or your own custom board?

    Next, I would like to know which EMAC core did you use?

    Is this MAC connected directly to an external PHY or routed to FPGA?

    Thank you

    Hello FJumaah,

    I am using DE10 Nano SoC development kit. I made few changes to linux kernel and made a custom one. I used ping to test.

    Appreciate your help.

    Hello,

    Would you please use this config file to build your linux and see if you can have ethernet working?

    Hello Fjumaah,

    Thank you very much for your help. I was away for a while so I couldnt test your suggestion in time. Now, I used your config file and seems my ethernet connection works as charm.

    Again, thank you
