FPGA and Firmware of USRP2

Dear all,I have downloaded the fpga code of USRP2 from:
git://ettus.sourcerepo.com/ettus/uhd.git
and compile with ISE10.1 like this:
cd uhd\fpga\usrp2\top\u2_rev3
make
but the output file in uhd\fpga\usrp2\top\u2_rev3\build is 0 byte.Is
there anything else I sould do?Is there any difference between the fpga
code with the code from:
git://git.ettus.com/ettus/fpga.git
I noted that two binary files should be burned into the SD card,a FPGA
image and a firmware image.Can anyone tell me where the firmware image
is compiled from?
Thanks!

you need to do “make bin”

also, ise10 may not build a working bin file. 12 is recommended.

prebuilt images can be found here:

they are built from the uhd.git repo
