It would seem like it is possible to get the Hardsploit ( Application GUI version 2.0 running on a Raspberry Pi 2 that is running Kali 2.1. The GUI is needed, in this case it is Xfce.

What you need to know is that this Kali 2.1 install is missing a few libraries. Unfortunately I installed too many in order to figure out which one would be the best solution. I will pick out a few which I really think helped in the end. If there are any others missing please add a comment. In the end I got the libraries to install and the application starts up.
apt-get install build-essential
apt-get install ruby ruby-dev ruby-qt4
As shown by Opal Security ( rest of the commands are the same as usual:
apt-get install cmake libsqlite3-dev dfu-util
gem install qtbindings activerecord libusb sqlite3
gem install hardsploit_gui 
Some lessons learnt so far:

  1. The software is buggy, it is work in progress. Expect it to crash. Make sure you save what you are doing, often. 
  2. It is a good idea to make a backup copy of the Database file. The file path can be found by going to About->Path->Database file. We did a reinstall of hardsploit_gui and it removed the database. You have been warned. 
  3. Dumping is very fast, compared to other solutions out there. We did a firmware dump of 4 MBs in 17.4 seconds at 25Mhz. 
  4. If you are having issues with the board and the lights are dimming and they seem weak it seems a firmware update (via bootloader) can fix it. Did for us, at least. (Updated: 06/02/2016)
