I agree that this question is more in the domain of GNURadio, but I do want to point out that RFNoC 4.0 blocks most certainly can have different numbers of inputs and outputs. A good example is the RFNoC Fosphor block:
https://github.com/EttusResearch/uhd/tree/master/fpga/usrp3/lib/rfnoc/fosphor https://github.com/EttusResearch/uhd/blob/master/host/include/uhd/rfnoc/blocks/fosphor.yml The GR 3.8 support for this block (and other UHD 4.0 RFNoC blocks) is in gr-ettus: https://github.com/EttusResearch/gr-ettus/blob/master/grc/ettus_rfnoc_fosphor.block.yml Best regards, Aaron On Mon, Jan 25, 2021 at 3:25 PM Marcus D Leech via USRP-users <usrp-users@lists.ettus.com> wrote: > > This is clearly a question for the discuss-gnuradio mailing list. > > Sent from my iPhone > > > On Jan 25, 2021, at 2:43 PM, dario via USRP-users > > <usrp-users@lists.ettus.com> wrote: > > > > > > Hi, > > I created a block with two output ports and one input port however when i > > try to connect it via stream endpoints gnuradio companion claims it doesn't > > know how to handle this.
