Has anyone been able to transmit with RFNoC Radio using the standard FPGA image
from UHD.3.15.LTS?
I have a clean installation and ran SigGen --> RFNoC: DmaFIFO --> RFNoC: DUC
--> RFNoC: Radio
Most basic flow graph ever. It does not work. I get a run-time error.
Traceback (most recent call last):
File "/home/nvd/Documents/top_block.py", line 169, in <module>

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

Working
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)

I am using 3.15.LTS.
Any ideas?
Thanks,
