I’m trying to do a simple repeater setup with my E320. I found that there’s an
example file that does essentially that, “rfnoc_radio_loopback.” However, right
out of the box, running this file gives the error:
\[ERROR\] \[RFNOC::GRAPH::DETAIL\] Adding edge 0/DDC#0:0 -> 0/DUC#0:1 without
disabling property_propagation_active will lead to unresolvable graph!
So I modified the file to do the connections manually and set
“skip_propagation" to true on that particular connection. When graph->commit is
called, I now get this error:
RuntimeError: AccessError: Attemping to read property ‘scaling@OUTPUT_EDGE:0’
before it was initialized!
I’m pretty stumped on this one. The only mention of setting a scaling property
is in some test programs, that call:
mock_source_term.set_edge_property<double>(“scaling”, 1.0,
{res_source_info::OUTPUT_EDGE, 0});
The DDC or DUC blocks do not have this method. Anything related to scaling in
the ddc_block_control appears to be protected or private. What am I doing wrong?
