Dennis Real osmocom-sdr-list at tildepipe.orgHi, I´m trying to get my FUNcube Dongle (V1.O NOT the Pro+) to work on Ubuntu 20.04.1 LTS but it doesn´t work. On a rasberry pi4 (Raspbian 10) the dongle is working in gnuradio-companion together with the osmocom-source. So the hardware seems to work. On Ubuntu I get following errors: 1. Gnuradio-companion as "osmocom Source" with device string "fcd=0": Executing: /usr/bin/python3 -u /home/reald/grc/osmocomsrc_fcd.py gr-osmosdr 0.2.0.0 (0.2.0) gnuradio 3.8.1.0 built-in source types: file osmosdr fcd rtl rtl_tcp uhd miri hackrf bladerf rfspace airspy airspyhf soapy redpitaya freesrp Using FUNcube Dongle V1.0 (hw:2) gr::log :INFO: audio source - Audio source arch: alsa gr::log :INFO: fcd0 - Audio device hw:2 opened gr::log :INFO: fcd_control0 - FunCube Dongle V1.0 initialized. gr::log :INFO: fcd_control0 - Dongle: FCDAPP 18.10 gr::log :INFO: fcd_control0 - LNA gain set to: 20 Traceback (most recent call last): File "/home/reald/grc/osmocomsrc_fcd.py", line 275, in <module> main() File "/home/reald/grc/osmocomsrc_fcd.py", line 253, in main tb = top_block_cls() File "/home/reald/grc/osmocomsrc_fcd.py", line 145, in __init__ self.osmosdr_source_0 = osmosdr.source( File "/usr/lib/python3/dist-packages/osmosdr/osmosdr_swig.py", line 1074, in make return _osmosdr_swig.source_make(*args, **kwargs) RuntimeError: boost::too_many_args: format-string referred to fewer arguments than were passed >>> Done (return code 1) 2.
