Dear all, I have more news on that. After following the steps provided by Nick, I finally succeed with the loopback. However, I have some observations: 1- At the Addendum, it is described that set_tx_streamer shall be used with E310. After many hours spent, I tried to set it also with X300 and

Dear Derek, I tried the link that you gave but no luck. 1) I disabled the use of timestamp and, dissecting the packets with wireshark, I cross-checked that the use_timestamp bit is 0. 2) I added the set_rx_streamer and issue_cmd to my flograph but nothing happens. I am not sure if both commands

Hello Dr Henarejos, Currently an RFNoC only flowgraph is not fully supported. What is missing is the issuing of the commands to start streaming and a mechanism to handle timestamps. Some modifications are needed to make these work. Nick Foster has done a write up on a few different ways of handlin

Dear all, I am playing with RFNoC on a USRP X300. I built a custom RFNoC FPGA image with the blocks that I need successfully and everything goes smooth. However, if I want to use a flowgraph with only RFNoC blocks (RFNoC Radio RX --> DmaFIFO --> RFNoC Radio TX), it does not work. The USRP doe
