USB-to-serial adapters > seem to be surprisingly variable. 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, Hiren > > Tim > > >
