Hey Greg,

sorry to hear about your E312 issues. You can build images for the E310
off of this branch: https://github.com/EttusResearch/fpga/tree/rfnoc-devel

We had some issues with the E310 which are mostly resolved. As of right
now, if you want to set up an RFNoC flow graph that only TX's, it won't
work, but we have a fix for that and then we can update the images package.

Cheers,
Martin
