Latest UHD version: error after update while trying to compile GRC model

Dear list,
I get a strange error when trying to compile a GRC model:

– Opening a USRP2/N-Series device…
Traceback (most recent call last):
File “/home/vl/GnuRadio/Surse/top_block.py”, line 43, in
tb = top_block()
File “/home/vl/GnuRadio/Surse/top_block.py”, line 28, in init
num_channels=1,
File
“/usr/local/lib/python2.6/dist-packages/gnuradio/uhd/init.py”,
line 74, in constructor_interceptor
return old_constructor(*args, **kwargs)
File
“/usr/local/lib/python2.6/dist-packages/gnuradio/uhd/uhd_swig.py”,
line 2044, in usrp_sink
return _uhd_swig.usrp_sink(*args, **kwargs)
RuntimeError: RuntimeError:
Please update the firmware and FPGA images for your device.
See the application notes for USRP2/N-Series for instructions.
Expected protocol compatibility number [7 to 9], but got 10:
The firmware build is not compatible with the host code build.

The weird thing is that it was working perfectly, before I updated it.
Any suggestion on how to fix this? (except the obvious regression to the
previous images).
Thanks.

Vlad.

Thats a bit odd. Well firmware compat 10 is for the latest images. So,
make sure you don’t have any old UHD library files hanging around in
/usr/lib, /usr/local/lib, /usr/lib64, /usr/local/lib64, and then pull
the latest master and install.

This indicates that your USRP-N2XX firmware is at level 10, while the
host side is expecting something else. Update your host side
UHD code to match the firmware side.

Marcus,
I’m familiar with installing UHD and then GNURadio, not so much with
updating UHD.
What are the differences?
Any suggestions or links to direct me?
Thank you.

Vlad.

Thanks Josh,
Since I’m a newbie with GRC+UHD would you care to elaborate on the
mentioned
procedure?!
How would I identify the “old UHD library files”?
After downloading the latest UHD from git clone
git://ettus.sourcerepo.com/ettus/uhd.git should I go ahead with the
typical
steps: cmake …/, make, make test, sudo make install, sudo ldconfig in
the
uhd build folder? or is there a different way of going about this?
Thanks!

Vlad.
