Hello, I'm trying to use fosphor (spectrum analyser) with my E310-sg1. I have UHD_004.000.000.rfnoc-devel-641-g8773fb2c on E310, I have compiled an FPGA bitstream by make command: `make.py fosphor axi_dma_fifo -I rfnoc/fpga-src/ -d e310 -t E310_RFNOC --fill-with-fifos -m 5` I also opened rfnoc_fosphor.grc with gnuradio-companion and removed all Qt dependencies from fosphor to see if it's working, then generated rfnoc_fosphor.py. When I tried to execute this, I'm getting the following output which terminated in seconds with an error. What may cause the problem? I'm a bit suspicious about the block that I'm using `axi_dma_fifo`. Shall I use any other block to support DmaFIFO? Thank you, Best, Enes. ---------------------------------------------------------------------------------------------------- linux; GNU C++ version 4.9.2; Boost_105700; UHD_004.000.000.rfnoc-devel-641-g8773fb2c -- Loading FPGA image: /home/root/usrp_e310_fpga_RFNOC.bin... done -- Detecting internal GPSDO .... found -- Initializing core control (global registers)... -- Performing register loopback test... pass -- Initializing AD9361 using hard SPI core...OK -- [RFNOC] ------- Block Setup ----------- -- [E300] Setting up dest map for host ep 0 to be stream 0 -- Setting up NoC-Shell Control for port #0 (SID: 00:00>02:10)...OK -- Port 16: Found NoC-Block with ID 12AD100000000000. -- Reading XML file: /usr/share/uhd/rfnoc/blocks/radio_e3xx.xml -- [E300] Setting up dest map for host ep 1 to be stream 1 -- Setting up NoC-Shell Control for port #1 (SID: 00:01>02:11)...OK -- [RFNoC Factory] block_ctrl_base::make() -- Reading XML file: /usr/share/uhd/rfnoc/blocks/radio_e3xx.xml -- [RFNoC Factory] Using controller key 'E3XXRadio' and block name 'Radio' -- block_ctrl_base() -- Reading XML file: /usr/share/uhd/rfnoc/blocks/radio_e3xx.xml -- Found valid blockdef -- NOC ID: 0x12AD100000000000 Block ID: 0/Radio_0 -- [0/Radio_0] block_ctrl_base::clear() -- [0/Radio_0] node_ctrl_base::clear() -- [0/Radio_0] block_ctrl_base::_clear() -- [0/Radio_0] block_ctrl_base::_clear() -- [0/Radio_0] Adding port definition at xbar/Radio_0/ports/in/0: type = 'sc16' pkt_size = '0' vlen = '0' -- [0/Radio_0] Adding port definition at xbar/Radio_0/ports/in/1: type = 'sc16' pkt_size = '0' vlen = '0' -- [0/Radio_0] Adding port definition at xbar/Radio_0/ports/out/0: type = 'sc16' pkt_size = '0' vlen = '0' -- [0/Radio_0] Adding port definition at xbar/Radio_0/ports/out/1: type = 'sc16' pkt_size = '0' vlen = '0' -- [RFNoC Radio] Performing register loopback test... pass -- [RFNoC Radio] Performing register loopback test... pass -- [0/Radio_0] radio_ctrl_impl::_update_spp(): Requested spp: 364 -- [0/Radio_0] radio_ctrl_impl::_update_spp(): Setting spp to: 364 -- [0/Radio_0] e3xx_radio_ctrl_impl::ctor() -- Setting time source to internal -- [0/Radio_0] e3xx_radio_ctrl_impl::_update_gpio_state() -- [0/Radio_0] Creating internal GPIOs... -- [0/Radio_0] Setting tick rate... -- [RFNOC] ------- Block Setup ----------- -- [E300] Setting up dest map for host ep 2 to be stream 2 -- Setting up NoC-Shell Control for port #0 (SID: 00:02>02:20)...OK -- Port 32: Found NoC-Block with ID 000000000000FFFF. -- Using default block configuration. -- Reading XML file: /usr/share/uhd/rfnoc/blocks/block.xml -- [RFNoC Factory] block_ctrl_base::make() -- [RFNoC Factory] Using controller key 'Block' and block name 'Block' -- block_ctrl_base() -- Reading XML file: /usr/share/uhd/rfnoc/blocks/block.xml -- NOC ID: 0x000000000000FFFF Block ID: 0/Block_0 -- [0/Block_0] block_ctrl_base::clear() -- [0/Block_0] node_ctrl_base::clear() -- [0/Block_0] block_ctrl_base::_clear() -- [0/Block_0] Adding port definition at xbar/Block_0/ports/in/0: type = '' pkt_size = '0' vlen = '0' -- [0/Block_0] Adding port definition at xbar/Block_0/ports/out/0: type = '' pkt_size = '0' vlen = '0' -- [RFNOC] ------- Block Setup ----------- -- [E300] Setting up dest map for host ep 3 to be stream 3 -- Setting up NoC-Shell Control for port #0 (SID: 00:03>02:30)...OK -- Port 48: Found NoC-Block with ID F1F0D00000000000. -- Reading XML file: /usr/share/uhd/rfnoc/blocks/dma_fifo.xml -- [E300] Setting up dest map for host ep 4 to be stream 4 -- Setting up NoC-Shell Control for port #1 (SID: 00:04>02:31)...OK -- [RFNoC Factory] block_ctrl_base::make() -- Reading XML file: /usr/share/uhd/rfnoc/blocks/dma_fifo.xml -- [RFNoC Factory] Using controller key 'DmaFIFO' and block name 'DmaFIFO' -- block_ctrl_base() -- Reading XML file: /usr/share/uhd/rfnoc/blocks/dma_fifo.xml -- Found valid blockdef -- NOC ID: 0xF1F0D00000000000 Block ID: 0/DmaFIFO_0 -- [0/DmaFIFO_0] block_ctrl_base::clear() -- [0/DmaFIFO_0] node_ctrl_base::clear() -- [0/DmaFIFO_0] block_ctrl_base::_clear() -- [0/DmaFIFO_0] block_ctrl_base::_clear() terminate called after throwing an instance of 'uhd::lookup_error' what(): LookupError: Path not found in tree: /mboards/0/tx_dsps/0 Aborted ----------------------------------------------------------------------------------------------------

Enes, this error message is unrelated to DmaFIFO. What exactly are you running? Is there a multi_usrp object involved?
