Failed to open bladeRF device with osmocom

[wilecoyote2019]

Hi!
I'm trying to use the bladeRf xa4 on ubuntu 18.04.03 LTS.

It came with gnuradio 3.7.11 and gr-osmosdr 0.1.4.

I installed libbladerf from git.

I can access the bladerf by bladerf-cli -i :

oam@oam-G3-3579:~/bladeRF/host/build$ bladeRF-cli -i
bladeRF> info

Board: Nuand bladeRF 2.0 (bladerf2)

bladeRF> version

libbladeRF version: 2.2.0-2018.12-rc3-2-ppabionic

Firmware version: 2.3.2
FPGA version: 0.10.2 (configured by USB host)

But when I try to access by osmocom, it cannot open the device :
sudo osmocom_fft -v -a bladerf=0 -s 2500000 -f 446000000

Opening nuand bladeRF with device identifier string: "*:instance=0"

FATAL: [bladeRF source] Failed to open bladeRF device *:instance=0

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?).

Thanks for your help!

Works for me using :
gr-osmosdr 0.1.5 (0.1.5) and gnuradio 3.7.13.5
Did you install gr-osmosdr from source?

git clone git://git.osmocom.org/gr-osmosdr
cd gr-osmosdr/
mkdir build
cd build/
cmake ../
make
sudo make install
sudo ldconfig

When running cmake you should see nuand bladeRF inside the enabled component list:
