Ethernet PHY register not detected

Hi,

 

I am trying to bring up GEM3 of Zynq ultrascale+ MPSoC on custom board connected to MICREL KSZ9031RNXCC PHY.

But petalinux gets stuck at the print of "Net: ZYNQ GEM: ff0e0000, phyaddr 3, interface rgmii-id". I tried to probe the mdio and mdc signals on the board and observed that there is no toggling happening.

I am using petalinux 2018.2 and vivado 2018.2.

Can you please help me how to proceed?

Thanks,

Siva

Hi Siva,

Please check to see if the LWIP baremetal works.

If this works, but seeing issues in uboot, you have to enable micrel PHY support macro in uboot config

 

Best Regards

Shabbir
