Does Zynq(7045) MIO support MII PHY ethernet(TI's DP83848)

Hi

I am working on ZYNQ(7045) based custom Board. Ethernet (DP83848) is interfaced to zynq through MIO lines. Configured as MII.  I  am testing ethernet using Lwip echo server in SDK. I get the following print once I run lwip echo server.

-----lwIP TCP echo server ------

TCP packets sent to port 6001 will be echoed back
link speed for phy address 0: 100
DHCP Timeout
Configuring default IP of 192.168.1.10
Board IP: 192.168.1.10
Netmask : 255.255.255.0
Gateway : 192.168.1.1

TCP echo server started @ port 7

But when I try to ping  from PC I get destination host unreachable.

and when I checked  RX_DV/MII_MODE  during reset is high (should be low for MII). Is lwip echo server support DP83848?.

Please help me.

 

Thank you

Sridevi
