[Discuss-gnuradio] FPGA and Firmware of USRP2

[陈敏]

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!
