Will the LX25 be large enough for J4 single processor? Not too worried about 
SMP, but I would like to run a CPU w/ an MMU on this board.

Hi Joh-Tob, quickly:

Yes.  This is 1v1, basically the same as the previous prototypes, with some 
component changes.

The device choice is XC6SLX25 or XC6SLX45, both in a IIRC 326 PBGA, with 
LP-DDR memory

LX45 is large enough for J32 (aka J4) MMU SMP, and probably UP J64.

Yes.  We need to do that.  We’ll have physical units people can walk away 
with at any conferences we go to.

We’ll take a look!
