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

###Prerequisites for Windows:

• Install git from https://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
    python -m pip install intelhex --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=https://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com

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

MinGW (https://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 https://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

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

• Install Em::Blocks (tested with Em::Blocks 2.30) from https://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

###Flash and use hydrafw on Windows: See the wiki https://github.com/bvernoux/hydrafw/wiki/Getting-Started-with-HydraBus

##How to build, flash and use hydrafw on Linux (Debian/Ubuntu):

###Prerequisites for Linux:

cd ~
sudo apt-get install git dfu-util python putty
wget https://launchpad.net/gcc-arm-embedded/4.7/4.7-2013-q3-update/+download/gcc-arm-none-eabi-4_7-2013q3-20130916-linux.tar.bz2
tar xjf gcc-arm-none-eabi-4_7-2013q3-20130916-linux.tar.bz2
echo 'PATH=$PATH:~/gcc-arm-none-eabi-4_7-2013q3/bin' >> ~/.bashrc
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
python -m pip install intelhex --allow-external intelhex --allow-unverified intelhex
cd ..

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

###Build hydrafw on Linux:

cd ~/hydrafw
make clean
make
