[Hackrf-dev] off frequency

[Bruce Barnett]

I wrote a simple shell script that should make it easier (I hope) to do the
firmware upgrade for your hackRF.

You do need to have either compiled the hackrf-tools, or to have installed
the hackrf package, i.e.

     sudo apt-get install hackrf  # on ubuntu

The shell script checks to make sure you have the proper executables,
downloads the firmware,  makes sure the firmware is the right  revision,
and once everything is in place, it will perform the upgrade.

it uses wget to download the file, unpacks it, and installs the firmware
Let me know if there are any problems.
I call it
     HackRFUpgrade

#!/bin/sh
# Script to update the HackRF firmware in a safer way.
# Based on info from
https://github.com/mossmann/hackrf/wiki/Updating-Firmware
# This script checks
#   (a) that both firmware files exist
#   (b) That they have the 'proper' hash. Update the hash values when
appropriate
#   (c) that all executables are correct and installed
#    I assume that the hackrf tools are installed
