PS EMIO and MIO etherrnet on zcu102

I am trying to implement PS EMIO ethernet as explained in xapp 1305/ 1306. I also want to add MIO ethernet. I  change the patch as in system-user.dtsi as attached here. I am also using the ps_pl_1g.dtsi (attached).

 

In order to implement MIO application, I changed platform_config.c following as to point to GEM3:

#define PLATFORM_EMAC_BASEADDR XPAR_XEMACPS_1_BASEADDR

 

I am also applying the patch 0001-fsbl-si570-clk.patch as explained in 

http://www.wiki.xilinx.com/PS+and+PL+based+Ethernet+in+Zynq+MPSoC

 

I still see the errors as:

In:    serial
Out:   serial
Err:   serial
Bootmode: LVL_SHFT_SD_MODE1
Net:   ZYNQ GEM: ff0b0000, phyaddr 9, interface gmii
PHY is not detected
GEM PHY init failed
No ethernet found.
U-BOOT for xilinx-zcu102-2017_3

 

Can somebody help what else I need to verify GEM0 and GEM3 functioning?
