Zynq PS Supported PHYs

[mustafa.su@esensi.com.tr]

At a first glance, is there specific PHYs that Zynq PS and Xilinx ethernet drivers for LWIP support or does not support.

I see a code branch at BSP drivers such that;

...

/* Marvel PHY flags */
#define MARVEL_PHY_IDENTIFIER 0x141
#define MARVEL_PHY_88E1111_MODEL 0xC0
#define MARVEL_PHY_88E1116R_MODEL 0x240

..

In evaluation board Marvell PHY 88E1116R is used. Is it a suggested PHY? Can we use any PHY from any manufacturer that has RGMII interface?

Thanks.

Yes.

Yes this is a widely used RGMII based PHY.

Basically you should find out what protocol the PS MAC on the PHY side uses (GMII, RGMII, etc).
