Hi Rob,
Thanks for your assistance.

Hi Rob,
Thanks for your reply :)

Also, it might help if you turn on "debug" logging (export
UHD_LOG_LEVEL=debug; export UHD_LOG_CONSOLE_LEVEL=debug) and run the
rfnoc_rx_to_file example. First try with a working block such as FFT and
then with the gain block and see if there are any clues.

I still don't know the answer to the problem, but one difference between
the program I sent you and the rfnoc_rx_to_file is the way in which the
streaming is started. In my example, streaming is started directly by
sending samples via the tx_streamer. In the rfnoc_rx_to_file program,
streaming is
Hi Rob,
Thanks for your help.

It is not just *my* block. the gain block from
"uhd/host/examples/rfnoc-
By the way, I have created a block controller for every UHD4 RFNOC block
that I have created and I simply compile them in-tree since I don't know
how to make this work OOT. This has the nice advantage that uhd_usrp_probe
can then know about my blocks.

Hi Cédric,
I don't see anything wrong. Given that you said the FFT block works but
your block doesn't, could it be something related to a c++ block
controller?
Attached is a program I use to test an individual block with the graph
"host => block => host". It might help to see if this works. Thi
Dear all,
I am trying to implement simple RFNoC block in my FPGA image (X310),
and test it using UHD C++ API.
However, none of my blocks worked when inserted between the DDC and rx_stream.
Both rfnoc-example/gain block (from upstream host/example)
and bare bones block from rfnocmodtool (passthrou
