Hi,
I have an rfnoc block with two output ports which is feeding the splitter block to duplicate each port. One pair is used to stream to the host, and the other is looped back to the radio via the DUC block. The active connections are reported as: Active connections: * 0/Radio#0:0==>0/PolConverter#0:0 * 0/Radio#0:1==>0/PolConverter#0:1 * 0/PolConverter#0:0==>0/SplitStream#0:0 * 0/SplitStream#0:0-->0/DUC#0:0 * 0/PolConverter#0:1==>0/SplitStream#0:1 * 0/SplitStream#0:1-->0/DUC#0:1 * 0/DUC#0:0==>0/Radio#0:0 * 0/DUC#0:1==>0/Radio#0:1 * 0/SplitStream#0:2-->RxStreamer#0:0 * 0/SplitStream#0:3-->RxStreamer#0:1 I'm getting this warning when trying to stream (to the host and the TX): [WARNING] [0/Radio#0] Received stream command, but not to output port! Ignoring. Along with debug info: [DEBUG] [RxStreamer#0] Received overrun message on port 0 [DEBUG] [RxStreamer#0] Received overrun message on port 1 L[DEBUG] [RxStreamer#0] Received late command message on port 0 [DEBUG] [RxStreamer#0] Received late command message on port 1 D I start the streaming with a timed command to the RX streamer like: rx_stream->issue_stream_cmd(stream_cmd); I'm not getting the red "TX" led illuminated on the N300, and I don't understand where or why these warnings are being created? Previous posts have mentioned this link (https://corvid.io/2017/04/22/stupid-rfnoc-tricks-loopback/) has helped but it seems to be down. How does one get a loopback in the fpga from rfnoc blocks to the radio TX? BTW: in the firmware I tie TEOV and TEOB to my TLAST in my custom block. Many thanks, Kevin
