OK, so it isn't wired up. I also need to remove the onboard 3.3 volt

This should give you an idea of how easy (hopefully) it is to
interface an FPGA board to the Beagle, provided you can configure a
bank to 1.8 volt IO.

Looks great! That FX2-BB board is pretty handy for prototyping stuff -
I've got one filled up with a low-end ARM processor & various audio
interfaces - works pretty well & the price is very reasonable for what
you get ($20 for the whole board - the Hirose connector alone is $7 from
Digi-Key).
Have you got a simple FPGA version of 'Hello World' through the ISE
tools yet? I usually do something like hook a switch/button to an LED
just to make sure I know how the flow works...
Not yet. I need to find look for some test code for the Spartan 3 board
and get the tools setup (I have a shortage of Windoze machines ...) Once
I get the board going, I need to remove the 3.3 volt oscillator from the
main board and get the same code running with the 1.8 volt oscillator.
Then the real fun begins :)
The photo is to give people an idea of where we are headed. Hopefully,
the board Chris (and others) come up with fewer components than the dev
board.
