Expected FPGA compatibility number 11, but got 9

[TARUNSAXENA]

Please help , I have been stuck in it for a month.

I am trying to run GNUradio on NI usrp 2921 on ubuntu 16.04, even installed uhd from source using link-

https://kb.ettus.com/Building_and_Installing_the_USRP_Open-Source_Toolchain_(UHD_and_GNU_Radio)_on_L...

even run uhd_image_downloader.py nothing happens.

Error-

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 9:
The FPGA build is not compatible with the host code build.
Please run:

 "/usr/local/lib/uhd/utils/uhd_images_downloader.py"
 "/usr/local/bin/uhd_image_loader" \
    --args="type=usrp2,addr=192.168.10.2"

 And one more thing there is no Fpga Image for Ni 2921 in uhd/image folder, so what image should i upload if it is needed to be.

Hello, 

  It looks like you have a mismatch between the UHD version and the GNU-Radio Version.  You certainly should have something happening when you run uhd_image_downloader. 

   I saw issues when manually installing UHD and GNU-Radio from source.  I have seen better results when using Pybombs. I find that your mileage may vary, since I had to download and build QT manually on Ubuntu 14.04. 

Is this using Ettus firmware, or NI firmware?  Are you planning to make changes to the FPGA?
