Hi guys, Although rfnoc supports different number of inputs and outputs uhd does not and you'll get all sorts of issues trying to address this. This is the reason why adder block also has a subtract output... Another issue is that loopback within fpga does not work. This means that signals in a chain have to originate or terminate on the host. If you have paths completely contained in rfnoc domain some streamers will not be enabled and you'll have to enable them manually. Finally remember that ports share the bandwidth of a single axi port so make sure total bandwidth is below it. For x310 axi bw is around 300 msps

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.
