Hi all,
I struggle in running my USRP B210 on Gnu Radio.
The USRP was running fine on a Windows installation (GR3.7). I recently
switched to ubuntu 20.04 to be able to use the repositories and installed
GR3.8.2 from PPA (using the nice description from Christophe; posted on
2020-09-24).
'uhd_find_devices' reports
[INFO] [UHD] linux; GNU C++ version 9.2.1 20200304; Boost_107100;
UHD_3.15.0.0-2build5
[INFO] [B200] Loading firmware image:
/usr/share/uhd/images/usrp_b200_fw.hex...
--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
serial: 8000036
name: Zhixun-wireless_B210
product: B210
type: b200
And 'uhd_fft -f 100M' loads a window showing a spectrum.
But when I try to run GNURadio and want to insert a UHD: USRP Source Block,
quite immediately a Crash Report launches. Trying to build the flowgraph anyway
(using a USRP source and a simple QT GUI Sink) a build error is displayed:
Generate Error: (NameError("'len_tag_name' is not defined"),
'uhd.usrp_source(\n ",".join((${dev_addr}, ${dev_args})),\n
uhd.stream_args(\n cpu_format="${type}",\n % if otw:\n
otw_format="${otw}",\n % endif\n % if stream_args:\n
args=${stream_args},\n % endif\n % if
eval(stream_chans):\n channels=${stream_chans},\n %
else:\n
(.. message continues, but is cut here).
Anybody knows, what might be the problem?
Thanks, Bernd
