[Hackrf-dev] And I can't make work 2 hackrf boards in GRC

[Cinaed Simson]

Hi - I had the same problem.

libhackrf, software tools, firmware/CPLD were all at saltest version -
namely 2015.07.2.

In order to make it work correctly GRC, I also had to install the latest
version of

  gr-osmosdr

in gnuradio.

I know how to update it in pentoo - I don't know how to do it in the
Mint OS.

Try

  apt-get install gr-osmosdr

and see if that works.
