Part Number: AM6421

Tool/software:

Hi,

          We are using mcu_plus_sdk_am64x_09_02_00_50  SDK.

         We are testing the enet_lwip_icssg loopback test example project, "enet_lwip_icssg_am64x-evm_r5fss0-0_freertos_ti-arm-clang" project on custom board.

         We also tried enet_icssg_loopback   test example project

        We are getting the below error        

Can please tell us how to resolve this issue

Thank you.

    Can you try latest release if starting new development ?

    Are you getting same error while working on AM64x-EVM ?

    Can you provide details about your custom board design ?

    Which PHY is there ?

    Which mode (RGMII / MII) ICSSG is in ?

    MDIO manual mode ?

    Regards

    Hi Ashwani,

      Thank you for the response.

      We are using DP83822 phy in our custom Board.

      The same PHY DP83822 is working with our earlier Custom Board with RGMII interface.

      In our new Custom Board, we have changed the Interface to MII.

       In addition to the above we would like to let you know, that in our MII custom Board we are unable to access DDR. Can I test this with out DDR usage.

       The purpose of this is to verify the new MII board for phy functionality, although we have DDR issue.

     Thank You.

    Thanks for update. Means you are facing issue for RGMII to MII migration?

    Just to be on the same page, you are using enet-lld or emac layer?

    You can refer ICSSG loopback example for AM243x-lp (which is ddr less implementation).
