    Till TI SDK 8.6 has few GPIO pins configured at u-boot stage for enabling of MDIO lines of CPSW9G for communication with QUARD Ethernet Board.

    SDK 9.0 onwards, the GPIO pins configuration at u-boot are removed and the MDIO lines of CPSW9G are enabled via switch settings on TI EVM.

    For enabling of MDIO lines of CPSW9G, make sure that below SW (SW2: CONFIG SW) Pin is in ON state.

    SW2.2 (pin2 from SW2) to ON state.



    If above is switch is not enabled, QUAD Ethernet Board PHYs will not be detected, can be observed from ETHFW debug logs.

    Please refer to below for the sample output of the ETHFW from User Guide.
