I remember taking several tries to get it going initially, but now I can't
work out why I had trouble.
Press Aux and hold
Press Power and hold
Hear tick from speaker
See red light flash on Aux
See uBoot screen
Timing doesn't appear to be much of an issue so long as the Aux button is down
when the power button is pressed. From pressing Power to uBoot screen is
between 1 and 2 seconds.
