Re: [Discuss-gnuradio] FATAL: No supported device found

Hi Bananpi,

On some Linux distributions the RTL dongle USB can be grabbed by other applications
at boot time, leaving it not available when you use gnuradio. If that is your issue it may
be resolved by blacklisting the RTL device.

Modify or create a file:   etc/modprobe.d/rtlsdr.conf

and add:

blacklist dvbusbrt128xxu
blacklist e4000
blacklist rtl2832

Then reboot.

Hi,

Bananapi / LUbuntu

After building GNURadio with the build-script and compiling / installing with success i can start gnuradio-companion or any gnuradio based py application but i get the following error messages.
===============
linux; GNU C++ version 4.8.2; Boost_105400; UHD_003.008.001-52-gd9e7a42d

Gtk-Message: Failed to load module "canberra-gtk-module" -> I know the reason of this error. This is easy to fix.
gr-osmosdr v0.1.4-9-g48045b59 (0.1.5git) gnuradio 3.7.6
built-in source types: file fcd rtl_tcp uhd rfspace

FATAL: No supported devices found to pick from.

Trying to fill up 1 missing channel(s) with null source(s).
This is being done to prevent the application from crashing
due to gnuradio bug #528.

Source has no sample rates (wrong device arguments?).
================

It seems that the USB RTL 2832U stick is not found by gnuradio.

I could see the device with dmesg and the rtl_test / rtl-test -t is successfull.
Any ideas ?

Andreas

YOu don't have the rtl support compiled-in to gr-osmosdr--perhaps because you were missing librtlsdr
 
Hi Marcus,
 
ok, so the problem is that the build-script didnt compile gr-osmosdr with rtl support because the librtlsdr wasnt installed from the build-script before compiling gr-osmosdr ?
 
What do i have to do now ? Should i uninstall gr-osmosdr and then compile and install gr-osmsosdr again ?

Which build script did you use?  build-gnuradio?   It definitely *does* build-and-install librtlsdr prior to build gr-osmosdr, but if that fails for some reason,
  gr-osmosdr will get built.

If you re-run it with "-v" it will give you more verbose output.
