DP83867E: Communicating with Linux

Part Number: DP83867E

Hi team,

I have an issue recognizing the PHY. This the behavior we are seeing:

  1. Our operating system is probing the MII lines, and via Xilinx Chipscope, we see that during initialization the master is attempting to read registers 0x2 and 0x3 of the PHY.
  2. We see the PHY responding with its ID from (0x2000, 0xA231)
  3. After this, the OS responds with “Could not attach PHY” for the Ethernet port

 

My questions are:

  1. Do you have any device tree source examples for they PHY (DP83867) that they might use for their processors that run the linux kernel in order to communicate with the PHY?
  2. Do you have any trouble shooting guides relating to connecting the PHY to any sort of Linux-based operating system?

Thank you.
