hi, i've developed a custom block in the FPGA and would like to run everything on the arm processor. my application consists of a web page served by python http.server module an such page sends commands via websocket to the gnuradio module associated with the custom FPGA block. the custom FPGA block is meant to perform some algorithms and output very low data rate that is then fed to a software only block that in turn should packetize that data and stream it from N310 to a PC. running the graph on a PC works perfectly. when running it from arm it runs while there's no output from the custom block but as soon as i enable its output i see that the sfp1 interface i'm using to stream data from arm to PC goes down and in turn web server is not reachable anymore and graph starts to report overruns, likely because the socket sender is stuck.
i understand that SFP1 interface is mainly for the FPGA and haven't tried yet the native gbit port but was wondering if there is any reason this is happening and any recommended best practice to run gnuradio graphs on zynq/arm. thanks, Dario Pennisi
