Felix, thanks for the catch. That looks like a problem I may have
introduced by accident a few months ago. This PR should fix it, hopefully:
https://github.com/EttusResearch/fpga/pull/47/files
Note I expect this would get merged into master and potentially not
backported to whatever version of uhd-fpga you're using, so I'd recommend
keeping what you have locally if it works for you :D
