Do I have a brick?

[hedwig]

I had a working Dreamplug2 until a few days ago when I needed to unplug it.

After restarting it, I couldn't find it's ip (or MAC) address on my LAN (I had previously given the device a static IP) despite the fact that the power LED is lit.  Multiple reboots didn't help.  I also can't ping the ip address.

I attached the JTAG to and tried to connect that way, but was met with an error that a serial connection could not be established.  One of the JTAG lights seemed to be lit.

UBoot was configured to boot off an 8GB SD card and I don't have a known working backup of the card.

Do I really have a dreambrick?  Any ideas to get this guy back up and running would be appreciated.
Thanks.
