how to build flash and use hydrafw on windows

How to build, flash and use hydrafw on Windows:

• Official compiler for hydrafw v0.10 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 up to GCC ARM 8-2019-q3-update (https://bugs.launchpad.net/gcc-arm-embedded/+bug/1570613) shall be avoided as they crash during link of chibios ...
  • This issue is fixed with https://launchpad.net/gcc-arm-embedded/+milestone/8-2018-q4-major or more
• Since 8600bd92a5ed083174e0867355f65a743dcfb9df, it is possible to use GCC 8.1 and newer to compile hydrafw

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

• Install git from http://msysgit.github.io
• Install Python 3.x see https://www.python.org/downloads/windows
  • Default Install Example: C:\Python3\
  • Add in environment variable PATH the path to Default Install: C:\Python3\
• Open a Command Prompt window (cmd.exe) and type following commands:

    git clone https://github.com/hydrabus/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

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"
