Hi all, 

I'm a new user of GNURadio and USRP. I used the script "build-gnuradio" to download the source and have installed them all.But when I tried the "uhd_fft", the terminal showed as belows: 

Linux; GNU C++ version 4.6.3; Boost_104800; UHD_003.008.002-168-gddae9468 

-- Opening a USRP2/N-Series device... 
-- Current recv frame size: 1472 bytes 
-- Current send frame size: 1472 bytes 
Please update the firmware and FPGA images for your device. 
See the application notes for USRP2/N-Series for instructions. 
Expected FPGA compatibility number 11, but got 10: 
The FPGA build is not compatible with the host code build. 
Please run: 

"/usr/local/lib/uhd/utils/usrp_n2xx_simple_net_burner" \ 

I followed the instruction as above. However, the problem still exists. I noticed that the images it downloaded is "uhd-images_003.008.002-157-gbe03e694.zip",which seemed to be not compatible with UHD_003.008.002-168-gddae9468. 

Can anyone tell me how to figure it out ? which of the files on http://files.ettus.com/binaries/images/  is number 11? 

Thanks very much.
