[arm-allstar] power up

[David McGough]

Hi Ken,

I greatly suspect power supply problems!

I had included and I have tried them to no avail.

Last night the unit from SparkFun did the same thing.  On power up the 
P/S LED just blinks at about 2/second and it will eventually come up at 
some point, unpredictably.   Last night I just left it blinking overnight 
and, when I got up this morning, it was in run.  This happens with the 
asterisk SD image and straight out of the box with only the eMMC.

But sometimes it just works.

I saw the suggestion about the power supply and I suspect that may be the 
problem.  Perhaps the current surge when the onboard regulator kicks in 
may be causing my wall wart to go into current limit.

I have ordered a couple of the Adafruit 4 ampere supplies and will report 
back in about a week..
