Hello, No, Ettus never followed up with a response and we never got past the problem.

I get an error when trying to use more than 2 output ports on a RFNoC block. I’ve designed a CE that has 9 output ports and when starting the gnuradio flowgraph it errors out. When I reduce the ports to 2 it works. If I increase the ports to 3 it errors out. I then made a simple modification to the ‘noc_block_split_stream’ block that is provided to have three output ports (also modified the associated XML files). It error out as well, in the same way. This test has Radio->DDC-SplitStream->host. Below are the messages produced by gnuradio when starting. Can the folks at Ettus please take a look as it appears to be a bug in UHD. I’ve attached the modified ‘noc_block_split_stream.v’ file so you can easily reproduce the error.
