2008-01-23 15:24:01 UART Tx but no Rx on BF537-EZKIT

Message: 50055 I just got this board in today for a new project for a new customer and am trying to verify that my u-boot, kernel, and maybe some of my apps that work on the BF537-STAMP will also work on the BF537 EZ-KIT.

Per my discussion(s) on this thread:

http://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&forum_id=39&_forum_action=ForumMessageBrowse&thread_id=25313

I assume that everything is compatible.

Anyway, I was able to get u-boot onto the board without much ado and I can now see it boot up on my hyperterm, however my keyboard strokes aren't being received. It looks like the UART on the board is transmitting, but not receiving.

Does anyone recognize this symptom?

Bill

Message: 50058 That was the second thing I checked. It turned out to be a hardware failure on my host machine. My COM port died. Sorry.
