Hi TI,

We have Ethernet design based on

FPGA ZYNQ 7000 XC7Z030 (MAC) -- RGMII
DP83826E (PHY) - RMII \ MII

Does the MAC (XC7Z030) which is RGMII compatible with our PHY DP83826E which is RMII\MII ?

Zynq-7000-TRM - P16.6

XC7Z030 :

DP83826E :

We succeed to send PING but the communication is not stable

What we can do about it

from PHY side
from MAC side

Can we replace DP83826E with DP83822 that have RGMII interface ??

DP83822 -- DATA SHEET

DP83822 -- EVM

Your help we will be appreciated

Thanks in advance,

Meir

Hello Meir,

RGMII standard is by definition not compatible with MII or RMII interfaces and the communication will not be reliable.

I suggest moving to DP83822 for RGMII support.

Hi Gokul,

Thank for your answer

Can you share design file for DP83822 EVM - Altium Project ?

Literature Number: SNLU179

Another question:

How we succeed to transfer data in UDP\TCP packet if the interface is not compatible ? or Ping the device ?

Does RGMII can work with RMII ?

Meir

RGMII can't work with RMII. So, you can't transfer any packets.

I'll check with our team on the Altium files and get back to you.
