Hi Joe, One thought is that the Rx Radio may never be getting the command to start streaming. Normally, this occurs by calling rx_streamer->issue_stream_cmd() which propagates from the rx_streamer block controller to the DDC block controller and ultimately to the Rx Radio block controller. If your custom block is in between and if your custom block controller does not properly propagate this command, it will never arrive at the Rx Radio. But, this may not make sense in your case because I would expect you would be receiving no data at all.
Another thought regarding troubleshooting of custom blocks is that if it is possible to "dynamically link" your block using streaming end points for the FPGA build, then you can configure a troubleshooting graph that is essentially tx_streamer->your_custom_block->rx_streamer so that you can verify that your block is behaving correctly. How are you talking to your custom image? C++/UHD? gnuradio? Rob On Tue, Apr 18, 2023 at 5:06 PM <jmalo...@umass.edu> wrote: > Hello, > > I have currently using my own custom RFNOC image.
