Zynq + Eth0 and Eth1

Hi,
We are planning a custom board baed on picozed wtih some changes
There has been items about Eth0 and Eth1 in the past.
What is the understanding now:
I was wondering if it is OK to have Eth0 and Eth1 both on PS side and then a shared MDIO and reset for them ?

Hello Terok,
From a hardware point of view using both Etho and Eth1 with a shared MDIO should work fine as long as the two PHYs each have a unique address. The more interesting question is software/OS support. This question is probably better addressed on the Xilinx Community forums since you are talking about custom hardware. Here are a couple of Xilinx Answer Records and forum posts that might get you started:
