Huh, usb-to-serial cable was acting funny. It seems to be doing its thing now.

BTW, If I hole boot switch and plug in power, I only see "CCCC...." on
the console. If I plug power without that, I am getting things. (which
seems to be stuck on uboot but thats another story).

Building new image right now and see how it goes.

Thanks a ton to all for your help.

cheers,
