GMII Interface from eMIO in a single Zynq Ultrascale+ HD bank

Jump to solution

Hi all,

 

I wonder if is possible to place a GMII interface from the eMIO in a single Zynq Ultrascale+ HD bank.

If I count the signals, the GMII interface has 27 signals, including the management signals (MDC, MDIO).

But the HD bank has only 24 pins.

 

Are there any signals from the GMII interface that are not used by Xilinx, and can be omitted?

 

Regards, Niels

I just recognized that I need to place 2 Gigabit Ethernet interfaces in the HD bank.

So i close this case as is is useless to use GMII in this case.

I have to use RGMII.

HI Neils,

 

This looks like the same question as this post ?

https://forums.xilinx.com/t5/Networking-and-Connectivity/GMII-to-RGMII-IP-core-in-ultrascale-HD-IO-bank/td-p/840292

 

The Networking and Connectivity board is the correct board for questions on GMII interface from EMIO and the 2nd post has traction

 

Regards,

Sandy
