Hi Rob, Thank you for your feedback !
I am relieved to learn that I'm not the only user experience issues using WR with N32x boards. Where did you find out that Ettus is presently looking into WR issues ? I'm asking because I can see a different thread from 2019 (http://ettus.80997.x6.nabble.com/USRP-users-N320-XQ-image-issue-using-sfp0-as-time-source-td13973.html) Which as far as I can see, no fix is implemented in uhd:master. BTW, I work with uhd4.0 - commit cf570707a2. We tried 2 different N320 boards, both resulted in the same behavior.

I have asked this list to see if anyone is presently using WR successfully, but have not had any replies. I know that Ettus is presently looking into WR issues.

When running without any argument, the PPS is correctly detected, I suppose it is because it uses as time source `internal`. Then when I try to use `sfp0` as a time source, I observed 2 different behaviors: Command run: ./test_pps_input --args="clock_source=internal,time_source=sfp0" --source=sfp0 1. I get the following message: [ERROR] [RPC] TDC Failed to reset. [INFO] [MPM.Rhodium-0.init.LMK04828] LMK initialized and locked! [ERROR] [MPM.Sync-0] TDC Failed to Reset! Check your clocks! Status: 0x0 [ERROR] [MPM.RPCServer] init() failed with error: TDC Failed to reset. Error: RuntimeError: Error during RPC call to `init'. Error message: TDC Failed to reset. And after this message, the PPS led does not blink anymore. 2. If I then run again the test after failing previously, this time I don't get any error message but a exception is thrown because no PPS was detected. We know that the OPNT Timing switch works when used with a OPNT node, where we get PPS and 10MHz signals. Do you think that there could be an issue when N320 and OPNT Switch try to sync together, or do you have any idea of what I could explore ? Thank you in advance for any help you can provide me with.
