Re: OMAP5: Booting build output

Chase,

I've got a 4-port USB serial adapter connected to my host, so, it
enumerates as ttyUSB5 on my host.

I'm connecting to the micro-USB port labeled DEBUG USB, and the LED
indicating debug power is lit, screen /dev/ttyUSB5 115200

Applying power, LEDs D1 and D2 light blue, but otherwise, nothing
lights; I don't see a link come up either on the eth port.
