Hi, I am having trouble getting my RFNoC block to work. I have connected a RFNoC setup as follows: Radio_0 (RX) —> My RFNoC Block —> Radio_1 (Tx) The output of the Rx radio is sent to the Tx radio via my custom RFNoC block. Hence, I’m not using an Rx streamer. This doesn’t appear to work. Is there any switch or configuration command I can issue to make this work? Thanks, Eugene

Eugene, this mode is currently not supported, and we're working on it right now. Sorry for the inconvenience!

Hi Martin, Will it work if I used a split_stream block to concurrently read Rx data using a rx streamer on a PC host?

Yes, that should work.

Tx streamer (from host)		 —>|			|	
						       | My RF block 	|—> Radio (Tx)	

I’ve extended my RFNoC block to have multiple inputs and a single output to the Tx radio, as shown: Tx streamer (from host) —>| | | My RF block |—> Radio (Tx) Radio (RX) —> Split_stream block —> | | | —> Rx streamer on a PC Host However, when I start both the Tx and Rx streamers on the PC host, I get a single packet (364 samples of sc16 data) from the radio that arrives at my RFNoC before no more data is streamed to that block. No data from the tx streamer appears at the RFNoC block. I verified this using the Vivado hardware debugger. The Rx streamer continues to receive data for a short while longer before timing out completely. The data from the tx streamer is not time-synchronized with the stream coming from the Rx radio. Does anyone have any idea what I’m missing here?

Eugene, that ascii-flowgraph was garbled somehow, can you re-send it? In your previous question there was not tx streamer, so I feel like I'm lacking some info here.

Hi Martin, I’m trying to get an RFNoC block to take inputs from both the host and the Rx radio, and output a stream to the Tx radio. These blocks are connected using C++, not GRC. I’ve included a PDF of the structure that I’m using. Will this design work?

Tx streamer (from host)		 —>|			|	
						       | My RF block 	|—> Radio (Tx)	

Some additional observations: When I start the Rx streamer, I can see that the custom RFNoC block receives 364 samples in the Vivado hardware debugger. After this initial 364 samples, everything freezes: no samples from either the host or the Rx radio are received by the RFNoC block. The debugger will be waiting for a trigger but no indication of any new samples is ever received. Also, no samples from the Tx streamer are ever received by the RFNoC block. This is so even if I disable the rx streamer.
