Hi Juan,

You're right; that message does mean the FPGA image is incompatible with
your UHD installation. You'll want to run the uhd_images_downloader that
came with your GNURadio installation. That should overwrite the images
stored on your host to a set of images that are compatible with the version
of UHD you're running.

What do you mean you reinstalled UHD? Could you give us the commands you
used to install GNURadio and UHD (if they were separate steps)? If you used
a package manager, GNURadio should come with an installation of UHD, which
GNURadio is linked against.

Regards,
Brent
