Hi Adam, This is a known bug that we are tracking on our internal issue tracker.
Can you please try building with these commits: https://github.com/EttusResearch/gr-ettus/commit/30302780a44f3f0b146e9b81f88e70c9d983f559 https://github.com/EttusResearch/uhd/commit/12a34d6ef6b9666e29a23039291138f989c7c2ce Note, using these commits, you'll still get the peak32() errors on the idle FPGA image load, however, it will not be fatal due to the FIFO connection error as seen with the error you posted..
