Using EMAC hps peripheral in FPGA mode

Hello,

I'm evaluating Cyclone V customized board. Using EMAC hps peripheral in FPGA mii mode, a MII to RMII converter to drive RMII Phy at 100Mbps.

Phy is being detected but could not establish connectivity.

Need help to understand the issue.

Thanks,

    Hi Snehal


    Could you try connecting the device to a network and try getting a dynamic IP?

      Hello Jingyang,

      PFA bootlog, connecting the EMAC to a network and issued the dhcp command also assigned IP manually, but unfortunately, it is still not working as expected & no response or connectivity established.

      Thanks,

    Hi Snehal


    Going through the device tree we found that one of the field in the device tree is incorrect.

    Could you try changing that and test it again please.


    In line 1031

    sysmgr: system-manager@0xffd08000 {

    compatible = "altr,sysmgr", "syscon";

    reg = <0xffd08000 0x00004000>;

    };


    The changes should be "compatible = "altr,sys-mgr", "syscon";"


    Regards
