FATAL: No UHD devices Found #22

Closed g0hww closed 7 years ago

g0hww commented 10 years ago

I've just managed to build ghpsdr3-alex on my Ubuntu 13.04 x86_64 machine. I've have also done a fresh build of gnuradio 3.7 today.

However, usrp_server doesn't seem able to find my USRP B100. Other tools are able to find it without issue. It makes no difference whether the UHD firmware is loaded or not.

darren@betty:~/src/ghpsdr3-alex$ usrp_server linux; GNU C++ version 4.7.3; Boost_104900; UHD_003.005.004-143-gde4ce9ea

*\ FATAL: No UHD devices Found Failed USRP init or not found. Exiting.

darren@betty:~/src/ghpsdr3-alex$ uhd_find_devices linux; GNU C++ version 4.7.3; Boost_104900; UHD_003.005.004-143-gde4ce9ea

UHD Device 0

Device Address: type: b100 name: serial: E3R10Z9B1

I managed to get it to find the b100 device by setting: hint["type"] = "b100"; in usrp.c :) I'll stick a more appropriate daughterboard in the b100 and see how I get on. Thanks.

Wow. OK. It is all working with my USRP B100 and BasicRX, with that tweak to the hint. Happy here. Sorry for the noise :)

Glad it is working fine now. I have posted your messages to google group sdr-widget and the usrp-server developer will hopefully update the code with the hint.

Thanks.

Thanks. I blogged about getting this working. My blog post should clarify the trivial bodge I made. I suspect that passing a device string hint as a command line option to usrp_server is probably the way to go, but I just substituted the string. See: http://www.g0hww.net/2013/10/qtradio-running-on-ubuntu-1304-with-usrp.html Finally, is there an IRC channel related to this stuff? I've not been able to identify one. If not, which would be the best mailing list? Sorry for turning this into a Q&A session.

If you build the opengl branch the QtRadio offloads much of cpu to the gpu.

Actually it is the usrp_server process that is applying a heavy load on this i7 haswell machine, far in excess of that of the QtRadio application.
