I get a set_tx_gain error running a basic signal generator through RFNoC Radio:

Signal Source -> DMA FIFO -> DUC -> Radio  (See image below)


This is equivalent to:

Signal Source --> USRP Sink    (Works fine)

Traceback (most recent call last):
  File "/home/nvd/Documents/top_block.py", line 169, in <module>
    main()
  File "/home/nvd/Documents/top_block.py", line 157, in main
    tb = top_block_cls()
  File "/home/nvd/Documents/top_block.py", line 84, in __init__
    self.uhd_rfnoc_streamer_radio_0.set_tx_gain(0, 0)
  File "/usr/local/lib/python2.7/dist-packages/ettus/ettus_swig.py", line 3235, in set_tx_gain
    return _ettus_swig.rfnoc_radio_sptr_set_tx_gain(self, gain, chan)
RuntimeError: _Map_base::at



I am using 3.15.LTS.


Any ideas?

Thanks,


Jeff
