DP83867IR: Tx/Rx Issues with Xilinx K26 SOM

Marco Rojas

Part Number: DP83867IR

Hi team,

I have a customer with the below request for help, let me know if someone could be assigned to this and help with a follow-up!

"Could I actually get some support with my implementation of DP83867IRRGZR?

For context, the ethernet PHY is on our main Host/Measurement board which has a Xilinx K26 SOM running Ubuntu. I have been having issues with Tx/Rx issues with DP83867IRRGZR i.e. I was unable to ping external devices, and many dropped RX errors. Would you be able to help with this issue?"

Thanks in advance!

Hi Marco,

May I ask for a block diagram on your system? Here are something I am looking for in the block diagram:

link partner
cable type and length
speed you are configure in.

Are you able to link up in your system?

If possible, could you provide a register dump from 0x0000 to 0x001F.

Regards,

Hillman Lin

Hi Hillman,

Being that the customer would have to share proprietary info, I'll take this to email and loop you into the existing thread.

Thanks!
