how to build flash and use hydrafw on windows

##How to build, flash and use hydrafw on Windows:

###Prerequisites for Windows:

• Install git from http://msysgit.github.io
• Install Python 2.7.x see https://www.python.org/downloads/windows
  • Default Install: C:\Python27\
  • Add in environment variable PATH the path to Default Install: C:\Python27\
• Open a Command Prompt window (cmd.exe) and type following commands:

    git clone https://github.com/bvernoux/hydrafw.git hydrafw
    cd hydrafw/
    git submodule init
    git submodule update
    cd ./scripts
    python get-pip.py
    python -m pip install GitPython --upgrade
    python -m pip install intelhex --upgrade --allow-external intelhex --allow-unverified intelhex

Note: 
For get-pip.py if you need a proxy for internet access set following variables before to launch
python get-pip.py:
set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com

###To build hydrafw firmware (with mingw):

MinGW (http://www.mingw.org) is required. The firmware is set up for compilation with the GCC toolchain GNU_ARM_4_7_2013q3.

• Install GCC toolchain GNU_ARM_4_7_2013q3 from https://launchpad.net/gcc-arm-embedded/+milestone/4.7-2013-q3-update
  • At end of Installation Install wizard Complete choose only Add path to environment variable
• Install MinGW from http://sourceforge.net/projects/mingw/files/latest/download?source=files
  • Default install: C:\MinGW\msys\1.0
  • During MinGW install choose msys-base (it includes minimal tools and make 3.81)
  • Launch msys shell from Default Install: C:\MinGW\msys\1.0\msys.bat

    cd in root directory(which contains directories common, fatfs, hydrabus, hydranfc ...)
    make clean
    make

###In case of error during build like:

Traceback (most recent call last):
  File "../scripts/hydrafw-version.py", line 14, in <module>
    git=Repo(search_parent_directories=True).git
TypeError: __init__() got an unexpected keyword argument 'search_parent_directories'
make[1]: *** [hydrafw_version.hdr] Error 1

Just execute

python -m pip install GitPython --upgrade

Then relaunch the build

###To build hydrafw firmware (with Em::Blocks):

• Install Em::Blocks (tested with Em::Blocks 2.30) from http://www.emblocks.org/web/downloads-main
• Launch Em::Blocks and choose from Menu File => Open... Ctrl-O with file hydrafwEm.ebp which is in root of hydrafw/
• Build the code with Menu Build => Rebuild all target files
