Dustin, It sounds like the software thinks the control port FIFO is filling up. Are you issuing a lot of timed commands, maybe far into the future? I wonder if issuing commands faster than they are being executed could cause the FIFO on the FPGA to fill up with commands. You could try increasing

Hi usrp-users, I've noticed something strange with an experiment I've been doing. The experiment is set up like a reflectometer. I'm using an X310 with a UBX-160 for transmit and both channels of a TwinRX for receive. In short, I put up a tone with the transmitter by applying a DC offset, tune to

Rob, The -I option is meant for out-of-tree blocks, which are supposed to follow the same structure as the example. The switchboard.yml file is missing a line that indicates where its makefile.srcs is: makefile_srcs: "${fpga_lib_dir}/blocks/rfnoc_block_switchboard/Makefile.srcs" See one of the

Ivan, to the best of my knowledge, there should not be any RX1 port. Instead, you should have two (coherent) channels "A" and "B" both allowing you to select one out of two available antenna ports when receiving ("TX/RX" or "RX2"). Cheers, Julian On 11/18/20 10:31 AM, Ivan Zahartchuk via
