I am new to this mailing list, but that does not mean that I have been following SDR activities here at osmocom and especially gnuradio actively. I am not a linux professional, but "intermediate beginner". I currently have a problem running my Hama Nano DVB-T Dongle which I cannot solve and therefore need to turn to you with the following problem:
I hava an Intel Pentium 977 machine running Ubuntu 12.04LTS in the 64bit version. I compiled and installed gnuradio using the script from Marcus Leech (http://www.sbrac.org/files/build-gnuradio)
I have an Hama Nano DVB-T Dongle which contains an RTL2832U Chip combined with the E4000 frontend.
When I try to access the Dongle via rtlsdr (either via sample programs in GRC or simply via rtl_test -s) I get
cb transfer status: 1, canceling...
Library error 0, exiting...
Speicherzugriffsfehler (Speicherabzug geschrieben) (engl.: "segmentation fault")
I found two threads regarding this problem in this mailinglist:
With respect to the former (1) I checked my version of libusb-1.0-0-dev which is 2:1.0.9~rc3-2ubuntu1
With respect to the latter (2) (and older post) I checked in my source of the rtlsdr library if the proposed change is included and it is.
So I do not have any clue how and where to proceed further. I'd be happy to give you any more information you need and try out patches. If you have any ideas or could point me to the right direction, I'd be very happy about
Thanks upfront for your consideration and best regards,
P.S.: The dongle worked on this machine before, but I do not remember if I had the 32bit Ubuntu version running and which versions of gnuradio, etc. were installed.
