I just uploaded two photos to http://groups.google.com/group/beagleboard/files
This one shows how I have connected my Beagle. I've tried to provide callouts for clarity. Do the connections look okay? Have I misconnected something? I was in the habit of plugging in power to the USB hub and then plugging the hub into the Beagle before powering up the Beagleboard over the 5v power jack. Maybe that was wrong?
This one shows the output of the Beagleboard on my Dell 2407WFP-HC monitor. The trouble is, I can't log in on that console with my USB keyboard. Robert Nelson kindly told me that I probably don't have a Revision C4-enabled u-boot.bin. I'll try the demo u-boot tomorrow.
