Hello Lecoq,

A new set of images will be released soon resolving the current compatibility version number difference, the pace of development on master has a small offset for the moment. For now here is the most recent commit which has compat 17 for both host and images.

Please let us know if you have any problems with this version.

I am setting up a new computer to talk to a x310 previously used on another system. I installed on this computer gnuradio and uhd on ubuntu 14.04 from the latest (yesterday) build-gnuradio script from Marcus Leech. All works fine with a N210.

However, with a usrp x310 on standard ethernet communication, uhd_usrp_probe --args addr= returns an error:

linux; GNU C++ version 4.8.4; Boost_105400; UHD_003.010.git-101-g4a1cb1f2
Error: RuntimeError: Expected FPGA compatibility number 18, but got 17:
The FPGA image on your device is not compatible with this host code build.
Download the appropriate FPGA images for this version of UHD.

I therefore runned (successfuly), as instructed, uhd_images_dowloader.py and then /usr/local/bin/uhd_image_loader --args="type=x300,addr=" which didn't show any error. I power cycled the x310 as I must after a fpga burn, but then the error of uhd_usrp_probe is still there.

Note than on the PC that was used previously with the x310 everything still works fine. On this one however, UHD_003.010.git-89-gb17b440d is reported for the uhd version... Is there a delay to be expected before the standard image fetched by uhd_images_dowloader is in agreement with the uhd version gitted by the build-gnuradio script ?

Thanks for your help.
