Thank you all for your help. Skip propagation was set to true and that fixed the problem!
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?
