we did update our FPGA images on the N-Series for the next upcoming release. You will need to update the device according to our manual (http://files.ettus.com/manual/page_usrp2.html). This change was necessary (among other things) for the N-Series to support our new UBX daughterboard.

Note that you might have to git pull again -- we didn't properly sync up code and images release last week, so you might be stuck between the code change and the images update. After git pulling, run uhd_images_downloader.

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.
