  • Hi,

    1. You mean the PHY link is up ? Can check Register 0x0001 to verify ?

    2. But pin does not go thru : Can you perform MAC Loopback and check whether the MAC interface is good ?

    Regards,

    1 the device and the computer are on the same network at 169.254.4.1 169.254.4.2, respectively.

    2 Settings and computers are connected to the same router, and ping is different.

    3 The equipment address is 169.254.4.1. Ping this address on the device side.

    4 How do I read the value of 0x0001? In what circumstances is it read? What is the value of reading? Please provide a detailed description?

    Hi,

    Please refer to User Guide of the EVM for details on MDC and MDIO Pin. You can use USB-MDIO Tool to connect to MDC/MDIO pin to read the register of PHY.
