I'm using a BladeRF x115 (purchased at DefCon21) in an Ubuntu 14.04 LTS Virtual Machine running under VMWare Fusion on MacOSX Mavericks, with USB3 support enabled. Have completed procedures detailed at https://github.com/Nuand/bladeRF/wiki/G ... ora_CentOS. GnuRadio and Osmocom builds completed successfully. BladeRF-cli reports:

Code: Select all

uname@ubuntu:~$ bladeRF-cli -p

    Backend:        libusb
    Serial:         e8149232708e43cc385ac5d2286d408b
    USB Bus:        4
    USB Address:    7

uname@ubuntu:~$

I am attempting the transmit test at the bottom of the above mentioned URL, and getting the following result:

Code: Select all

uname@ubuntu:~$ osmocom_fft -a bladerf=0,fpga=~/Downloads/BladeRF/hostedx115.rbf -s 2000000 -f 446000000
gr-osmosdr v0.1.1-9-gc65d205d (0.1.2git) gnuradio 3.7.3
built-in source types: file fcd rtl_tcp 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?).
uname@ubuntu:~$

Based on the 'built-in source types:' output, I'm wondering if maybe bladeRF support didn't get built in when I built GNURadio, but that's my only guess thus far.

For reference, here is more detailed output from bladeRF-cli:

Any ideas or suggestions as to what may be going on?

The bladeRF library has to be installed before gr-osmosdr builds in order for it to get included. If you rebuild gr-osmosdr it should add bladeRF to osmosdr sinks/sources.

Thanks! I ended up having to rebuild the BladeRF software (rather than use the prebuilt versions for Ubuntu.)
