DP83TD510E-EVM: EVM doesnt connect

Part Number: DP83TD510E-EVM
Other Parts Discussed in Thread: DP83TD510E, USB-2-MDIO

My customer has received the DP83TD510E-EVM and ran into an issue.

The Ethernet Phy on the DP83822 Rev.2 Board doesn’t seem to make a connection over RJ45 interface. The built in LEDs do not turn on.

The power supply does seem to work. The LED D15 is turned on.

What could be the issue here?

Thanks for helping.

Regards,

Gokhan

  • Hi Gokhan,

    Here are some of my questions to learn a little bit more about the customer set up:

    1. Is the user able to read registers from the DP83TD510E and the DP83822 using USB-2-MDIO? 

    2. What power source is the user using? And have they made any modifications to the jumpers or R24?

    3. What debug methods has the user already tried? And, what were the results?

    Thank you!
