I am a newbie on UHD RFnoc. I setup Ettus Research X310 with a RF sig gen signal output to Rx2 and a VSA connected to Tx/Rx output. As long as Rx2 input and Tx/Rx output are on a different radio block, the app worked fine. But when I tried to setup Rx and Tx on the same radio block. The app aborted with an error message:
[ERROR] [RFNOC::GRAPH::DETAIL] Cannot create route from device:1/sep:2 and device:1/sep:2, no route was found!
Error: RuntimeError: Cannot create route from device:1/sep:2 and device:1/sep:2, no route was found!
Setup Details
Agilent signal generator connected to X310 RF2 port input. R&S VSA connected to X310 Tx/Rx port output.
I expected rfnoc_radio_loopback would initialize properly even when the rx and rx radio block ID is the same. Instead, the app failed to initialized with an error.
Actual Behaviour
The example app failed with the following error msg:
[INFO] [UHD] linux; GNU C++ version 13.2.0; Boost_108300; UHD_4.7.0.0-0-ga5ed1872

Error: RuntimeError: Cannot create route from device:1/sep:2 and device:1/sep:2, no route was found!
Steps to reproduce the problem
Command line to reproduce the issue:
./rfnoc_radio_loopback --rx-freq=800000000 --tx-frequency=815000000 --rx-ant=RX2 --tx-ant=TX/RX --rx-bw=5000000 -tx-bw=5000000 --rx-gain=20 --tx-gain=3 --ref external --rx-blockid=0/Radio#1 --tx-blockid=0/Radio#1
Note: if I specified tx-blockid=0/Radio#0, the app started up properly and produced output signal on the TX/RX port as expected.
