[Hackrf-dev] Jawbreaker firmware update fail

[Graham Cottew]

Thanks Ryan.

Step 1 done.

Step 2 in progress. I may be making life even more difficult than I need as I am running on a Mac. 

But before I had this flash problem I have been going great guns with gnu radio 3.7, gr-osmosdr and with the Jawbreaker working well on receive and transmit using a bunch of gnuradio companion programs I have created. Put up a lovely discone wide range antennae about 20 meters above ground and just starting to get into it!

If the Mac proves to hard to get all the dependancies running on then I am building an ubuntu 13.04 notebook up as we speak (I also have a number of Ubuntu VMs running gnuradio 3.6.4 and 3.7 that work fine with the Jawbreaker as well).

You'll obviously also need other build dependancies up and running.  The trickiest being  https://code.launchpad.net/gcc-arm-embedded , but you can read the readme.md located here https://github.com/mossmann/hackrf/tree/master/firmware
