Re: [Discuss-gnuradio] two versions of uhd installed?

The repos are outdated.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  --------------------------------------------------  -- UHD Device 0  --------------------------------------------------  Device Address:      serial: 311D131      addr: 192.168.10.2      fpga: HG      name:       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()  linux; GNU C++ version 7.3.0; Boost_106501; UHD_003.010.003.000-0-unknown    -- X300 initialization sequence...  -- Determining maximum frame size... 1472 bytes.  -- Setup basic communication...  Traceback (most recent call last):    File "./uhd_const_wave.py", line 203, in <module>      main()    File "./uhd_const_wave.py", line 191, in main      tb = top_block_cls(samp_rate=options.samp_rate, freq=options.freq, gain=options.gain, address=options.address)    File "./uhd_const_wave.py", line 98, in __init__      channels=range(1),    File "/usr/lib/python2.7/dist-packages/gnuradio/uhd/__init__.py", line 122, in constructor_interceptor      return old_constructor(*args)    File "/usr/lib/python2.7/dist-packages/gnuradio/uhd/uhd_swig.py", line 3012, in make      return _uhd_swig.usrp_sink_make(*args)  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
