[hpsdr] programming FPGAs

[Christopher T. Day]

Len,

It's better than that. The FX2 on Ozy can bootstrap itself and the
on-board Cyclone II configuration device directly over USB with nothing
else required.

I presume that bootstrapping the startup code to Ozy could use something

as simple as the Altera ByteBlaster (there's a reference at 
<http://opencollector.org/history/freecore/Build%20your%20own%20ByteBlas
ter!.htm> 
as well as a more official doc at 
<http://www.altera.co.jp/literature/ds/dsbyte.pdf>).  I've tried to find

the equivalent for the Maxblaster, but given that a USB interface will 
be available through Ozy (this is great news, Phil.  Probably obvious to

everyone except me!) it would seem that a really basic 'use once' 
interface is all that is required.

Please correct me if I am completely wrong - it has been known :-)
