[Arm-dev] Debug port fixed - Re: pcDuino Nano lite

[Robert Moskowitz]

Debug port is fixed and I now get the console messages.  It seems to 
have been a faulty wire connection.

Next week it is IEEE 802 in Atlanta, so it will be a week before I test 
out Centos on the sata on this card.  If all goes well with that, I move 
this board to a 'good buy'.  But I would like to get some performance 
testing tools to see how it compares with the Cubieboard2.
