The repos are outdated. I ran into the same problem when first getting
started too.
You need to compile both UHD and GNUradio from source to get the
versions you want.
Ettus has a great (very thorough) guide on how to do this.
https://kb.ettus.com/Building_and_Installing_the_USRP_Open-Source_Toolchain_(UHD_and_GNU_Radio)_on_Linux
*tip: instead of 'make' you can type 'make -j 2' in order to greatly
speed you the compiling process. (only if you have 6 gigs of ram or more)
Feel free to post in this thread again if you get an error.

Hi all and happy new year,
It is not clear to me if this question is a usrp or gnuradio related
so I send it to both lists. Apologies for the duplication.
----
I have installed a clean version of gnuradio to an ubuntu box
from repos with apt-get.
I then installed from the ettus site the uhd files using:
"Using binaries provided by Ettus Research":
sudo add-apt-repository ppa:ettusresearch/uhd
sudo apt-get update
sudo apt-get install libuhd-dev libuhd003 uhd-host
After trying to communicate with my newly bought X310
I got some error messages about incompatibility of FPGA images that
I fixed with appropriate downloading/burning the new images to FPGA.
Now commands like uhd_find_devices and uhd_usrp_probe work perfectly, eg,
anastas@AA-1:~$ uhd_find_devices
[INFO] [UHD] linux; GNU C++ version 7.3.0; Boost_106501; UHD_3.13.0.1-release

addr: 192.168.10.2
fpga: HG

product: X310
type: x300
telling me that I am using UHD_3.13.0.1-release
PROBLEM: however when I run a simple uhd example (eg, uhd_const_wave.py)
I get the following error:
anastas@AA-1:/tmp$ ./uhd_const_wave.py
Warning: failed to XInitThreads()

RuntimeError: RuntimeError: Expected FPGA compatibility number 33, but got 35:
The FPGA image on your device is not compatible with this host code build.
Download the appropriate FPGA images for this version of UHD.
Please run:
"/usr/lib/x86_64-linux-gnu/uhd/utils/uhd_images_downloader.py"
Then burn a new image to the on-board flash storage of your
USRP X3xx device using the image loader utility. Use this command:
"/usr/bin/uhd_image_loader" --args="type=x300,addr=192.168.10.2"
For more information, refer to the UHD manual:
http://files.ettus.com/manual/page_usrp_x3x0.html#x3x0_flash
------------------------------
So it seems that it is using a different uhd library
(UHD_003.010.003.000-0-unknown) than the one I installed from ettus...
How can I fix this?
Thanks
Achilleas
