Hi, I'm new to RFNOC development. I have an X310 with an SBX on slot A, and I want to do a loopback from antenna port RX2 to TX/RX using RFNOC blocks. I tried connecting 0/Radio_0 ==> 0/DDC_0 ==> 0/DUC_0 ==> 0/Radio_0 by the following commands:
rx_graph->connect(radio_ctrl->get_block_id(), ddc_ctrl->get_block_id()); rx_graph->connect(ddc_ctrl->get_block_id(), duc _ctrl->get_block_id()); rx_graph->connect(duc_ctrl->get_block_id(), radio_ctrl->get_block_id()); and UHD gives me Error: RuntimeError: On node 0/Radio_0, output port 0 is already connected. What am I doing wrong here? Please help. Regards, Alex
