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, msys2 and clone hydrafw):

Install MSYS2 + MINGW64 from https://www.msys2.org
- Install of mingw-w64-x86_64-gcc + cd src/build-scripts && make clean all is to rebuild pre-built windows src/build-scripts/hex2dfu.exe so it not mandatory
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
Launch MSYS2 MINGW64 shell and type following commands:
- Example installation of GNU_ARM_4_9_2015q3 to D:\GNU_ARM_4_9_2015q3\bin
- export PATH=$PATH:/D/GNU_ARM_4_9_2015q3/bin

    cd ~
    pacman -S git make mingw-w64-x86_64-gcc
    git clone https://github.com/hydrabus/hydrafw.git hydrafw
    cd ~/hydrafw
    git submodule init
    git submodule update
    cd src/build-scripts
    make clean all

To build hydrafw firmware (with mingw):

MSYS2 MINGW64 is required. The firmware is set up for compilation with the GCC toolchain GNU_ARM_4_9_2015q3.

Build the firmware

    cd ~/hydrafw/src
    make clean
    make
