Re: RFNoc Rx Radio to Socket

[Paul Atreides]

Taylor:
Marcus is correct. Have you synthesized a custom image that contains the pass 
through block?
I also noticed that you have skip_tag_propagation set to true from the 
tx_rx_loopback example, but you’re not doing a loopback. 
What are you trying to do?
