how to build flash and use hydrafw on windows

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

• Official compiler for hydrafw v0.8beta release is GCC ARM 4.9 2015q3(GNU_ARM_4_9_2015q3)
• This new version versus GCC ARM 4.7 2013 q3 improve lot of stuff (mainly it generate better/more compact code and GDB debugger support python ...)
• WARNING: GCC ARM 4.8.x & GCC ARM 5.0/5-2016-q1 shall be avoided as they crash during link of chibios ...

###Prerequisites for Windows (install git, python and clone hydrafw):

• 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_9_2015q3.

####Prerequisites for Windows (install gcc arm, mingw):

• Install GCC toolchain GNU_ARM_4_9_2015q3 from https://launchpad.net/gcc-arm-embedded/+milestone/4.9-2015-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

####Build the firmware

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

####In case of error during the step "Build the firmware"

1. With error:

Traceback (most recent call last):
  File "../scripts/hydrafwversion.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

2. Just execute:

python -m pip install GitPython --upgrade

3. Then execute again the step "Build the firmware"
