Hi all,
Are there any RFNoC GRC examples available for the N3XX device streaming data to a host using a SFP port? Is the N3XX like a E3XX series in that the GRC has to be run on the Zynq arm device or can it be configured to run like a X3XX device where the external Host PC runs the GNURadio, connecting the various CE blocks on the X3XX? I assume the Host needs to be controlling the ARM for configuration on the RJ45 port prior to setting up communications on the SFP ports? Does the N3XX need to use the same approach (https://kb.ettus.com/Streaming_processed_data_from_the_E31x_with_GNU_Radio_and_ZMQ) as the ZMQ example to transport data to an external Host for GNURadio processing?
I have been trying to figure out from the FPGA build and UHD driver how it operates. The CE engines seem to go via ADI DMAC cores where the destination appears to be either other RFNoC CE engines on the bus or the ARM external DDR3 memory. Can these address the DMAs associated with the SFPs and skip the external ARM memory DMA stage?
A top level description of how the various ingress /egress bus communications are addressed by RFNoC would be very helpful.
