Hi Andrew, This is true of all RFNoC images. The "ctrl" setting refers to whether or not that endpoint has a connection to the control crossbar, which is used for sending control packets (e.g., register reads/writes) to/from RFNoC blocks. Because you can send control packets to any RFNoC block from any control port master, you only need one endpoint with a control port to be able to do control communication with all the RFNoC blocks. So you have to have at least one endpoint with a control port and having more than one wastes logic because currently only the first one will be used.
