Hi,
I have the same error with c++ example rfnoc_radio_loopback.cpp, if I set --tx-blockid='0/Radio#0' --tx-chan=0 --rx-blockid='0/Radio#0 --rx-chan=1 when I want to use RF-A Tx/Rx and RF-A Rx2 ports on one single daughter board, then I have to build the graph manually and disable this property_propagation_active at connecting nodes. sincerely Kasim ________________________________ From: [email protected] <[email protected]> Sent: 18 March 2021 19:27:46 To: [email protected] Subject: [USRP-users] Disabling property_propagation_active - [ERROR] [RFNOC::GRAPH::DETAIL] Hi all, I get the following error when running gnuradio with a RFNoC block created following UHD 4 guide.
