I'm trying to get an N321 working with a WhiteRabbit switch.
First, if I don't try to set the timing to sfp0, everything is fine:
myprompt:./rx_samples_to_file --args
"addr=192.168.10.2,clock_source=internal,master_clock_rate=250e06" --file
blob.dat --type short --duration 1 --freq 75010000 --ant "TX/RX" --channel 0

Done!
However if I include the required argument to set the timing source to SFP0,
then I get a TDC error:

I've loaded the WX firmware and am using UHD-3.15-LTS.
Any ideas what is going on?
