I got a step further. The rfnoc domain for grc can be defined by a file
rfnoc.domain.yml.
Now I can connect the module and generate a Python file from the flowgraph.
The connections still do not work at run time, though , see below.
I have defined 'connect:' and 'cpp_connect:' in rfnoc.domain.yml, but this
definitions have no effect since this file is not read at run time and not
included in
rfnoc_test1.py either.
Any suggestions?
Thanks and best regards,
Erik

Betreff: [USRP-users] gr-ettus and GNU radio v3.8
Have there been any efforts yet to port gr-ettus to the gnuradio master branch?
I made some trials today with gr-ettus under gnuradio-master and at least was
able to compile and install it (except for fosphor which seems to need Qt4).
Automatic conversion of the grc xml files to the yml format was not possible,
so I converted one by hand (uhd_rfnoc_dma_fifo).
I got so far that the block shows up in grc and most error messages went away.
There are still errors, however, about 'Domain key "rfnoc" is not registered'
for the input and output ports. This is probably the reason as well why I
cannot connect anything to this block (red arrows).
Any ideas? How do I register the rfnoc domain? Are there any serious reasons
preventing the rfnoc blocks from working under v3.8?
Best regards,
Erik
