We are trying to port uClinux on our MCF5372L custom made board. We have
the fec.c modified to support SMSC LAN8700 (We are able to get the
proper PHY ID thru MII). The device boots up with the attached message
below, but fails to get an IP address even though DHCP client is
enabled. We tried setting the static IP but no response for the ping
command. Can anyone let me know what could be the problem?
Does your SMSC LAN8700 support code in fec.c properly set
the internal "link" state?
Search for "fep->link" use in the driver code. Without this
being set transmit won't do too much.

Greg
Thanks and Regards
