Hacking USRP gateware (European GNU Radio Days 2023)

European GNU Radio Days 2023 presentation by Gwenhael Goavec-Merou

Two Ettus Research USRP hardware platforms are investigated for adding custom functionalities to the FPGA gateware: the B210 on the one hand, and on the other hand the X310 through the RFNoC framework.

This presentation will demonstrate how to integrate a standalone, stream independant Verilog code either hand written or produced using Amaranth or LiteX, accessing Front Panel GPIOs for generating synchronization signals (1-PPS). A second demonstration will timestamp the datastream on an external synchronization signal.
