[U-Boot] U-Boot Ethernet Connectivity Issues

I have a Windows 7 development machine that I cannot verify ethernet connectivity with my P2041RDB QorIQ platfrom running u-boot.  The two devices are connected using a crossover cable.  When I try to ping from the P2041 to the Windows 7, the ping returns No link.  I verified that my dev machine and cabling is fully functional by replacing the P2041 with a Linux machine.  The Linux machine and Windows machine were both able to successfully ping one another.

My settings are the following:
Windows 7 Development machine has:
ipaddress = 192.168.1.2
netmask = 255.255.255.0
gateway = 191.168.1.1

P2041RDB:
U-Boot 2011.09-00000-g2c02d1d
ethaddr=00:04:9F:02:1C:00
ipaddr=192.168.1.10
netmask=255.255.255.0
gatewayip=192.168.1.1
ethact=FM1 at DTSEC1
netdev=eth0

ping 192.168.1.2
FM1 at DTSEC1: No link.

The cabling is good; I am in the correct port for DTSEC1, the ethernet address is not multicast or local.  Someone please help to troubleshoot.

With u-boot how do I verify that the ethernet is enabled, what speed and duplex the device is using, etc.?

Thank you,

-Joel
