Hi, i'm trying to optimize FPGA consumption and on N310/UHD4.1.0.1 i am testing a block that needs only 2 inputs and no outputs. since i don't need to stream any data in/out of the FPGA i declared a single streamer with control only and declared no connection between it and any block in the yml and this way i can see i can read and write registers. the issue arises when i try to stream data to the block: if i have no outputs declared, inputs will not receive anything. if i have 1 output connected to a streamer, connected to a null sink, i can receive from the first input, if i have 2 outputs connected to two streamers connected to null sinks i can receive on both inputs. is there any way i can get rid of those useless outputs and remove at least 1 endpoint? if i declare i need a single endpoint with no data why does it complain if i don't declare buff_size in the yml? my rfnoc block uses a noc shell that outputs axi stream payload which i adapted for programmable number of inputs and outputs. It seems to me the issue is not on the FPGA side as the backend block seems to properly report information and o don't see any connection in NOC shell between input and outputs other than in there...
Thanks, Dario
