Yes, here's a dump of the pertinent environment settings, as well as the dmesg
output as promised. The weird thing is that after I get the 'link down'
message the board seems to boot ok? What am i missing here?

BJ,
Did you change the default bootargs variable in u-boot to use ip=dhcp
rather than ip=off?

Subject: RE: Questions about DM355 DVEVM
On a somewhat different note regarding the DM355. Did you have to take
any special steps to get the onboard Ethernet working properly? We have
DM6446 boards that we used for development and have a project going with
them (and our own custom boards). Both are functioning without any
major issues however when we try to boot the kernel on the dm355 the
Ethernet port always comes up with 'no link' I seem to recall just
being able to plug in a cable and 'ping' the eval boards. Is there an
initial step that we've missed? Thanks. I can attach a clip from our
dmesg output when I get only my development box if it'll help at all.

notes and schematics". Does this mean the DM355 does not have an on-chip
MAC and that it requires an external MAC/PHY chip? If I wanted to create
a DM355 solution with two ethernet interfaces such as LAN and WAN, would
I need to write special drivers or require major board changes? The
MAC/PHY is external - it is attached to the AEMIF bus. To implement
another ethernet interface you need to modify the CPLD code to add an
additional chip select and modify drivers for the address space change.

Another alternative, if the changes that Steve suggests are more than
you want
to do, would be to make a second network device available via the USB
port.
We've used a USB to ethernet dongle for debugging our 355 based board,
and it
works fine.
A third option could be to use an ethernet card for the SDIO (SD/MMC)
slot.
I don't know if there are cards available for wired ethernet, but we are
using
a wireless (802.11a/b/g) card from CardAccess.
