Re: [Discuss-gnuradio] [USRP-users] FPGA compatibility number X310

[Derek Kozel]

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.
https://github.com/EttusResearch/uhd/commit/b17b440d75a874b404f5493cc8ca9a1d6dbeb08c

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

Regards,

Derek

Hello,

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=192.168.10.2 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=192.168.10.2" 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.

Best,
