Been using uhd/rfnoc for 9 months now with no comparability problems i
couldn't fix.
My last devel version was from the beginning of June.
Upgraded rfnoc and rebuilt from scratch the pybombs rfnoc packages via the
getting started wiki.
I have an x310 USRP
Redid the place and route with the new rfnoc build.  Now i get the dreaded
comparability mismatch.  In the past this was fixed because i built the bit
file or ran with uhd of two different versions.  This is on one machine and
should not have this problem.  Where do i start debugging this problem?

Error: RuntimeError: Expected FPGA compatibility number 35, but got 36:
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:

 "/root/rfnoc/lib/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:

"/root/rfnoc/bin/uhd_image_loader" --args="type=x300,addr=192.168.40.2"
