[MinnowBoard] Headless Operation

[eviljoel]

Hello John,

Good to hear someone has it working headlessly. Can you tell me the
version of Linux you are using? Can you also tell me your firmware version?

I'm trying to run it headless over SSH. If I run into problems, I don't
mind plugging it into a monitor from time to time, but generally I was
hoping to run it without a monitor.

I'll likely try using the serial console later this weekend. It will be
a good way to see if Linux is even starting.

Thanks,
eviljoel
