[Discuss-gnuradio] USRP2 FPGA now builds on ISE12

[Matt Ettus]

The USRP2 FPGA image can now be built with ISE 12.x.  ISE 11.x probably 
also works, but since 12 is a free upgrade from 11, I suggest you use 
12.  Everything still works on ISE 10.1.03 as well.

One additional change is that both the plain (Raw Ethernet) and UDP 
versions (for UHD) are in the same tree now.  Build the plain version with:

        make bin

in the usrp2/top/u2_rev3 directory, and the UDP version can be built with:

        make -f Makefile.udp bin


This experimental branch is called ise12_exp and you can get it from our 
git repository:

        http://code.ettus.com/redmine/ettus/projects/show/fpga

It does not quite meet timing yet, but it is plenty good for 
experimental work.  We will be working on timing closure in the next 
couple of weeks.  Any feedback would be much appreciated.



Huge thanks go to Ian Buckley for his help in this porting effort.

Thanks,
Matt
