How to build

• Windows host
  • Install Python3.
    When installing, enable "Add Python 3.xx to PATH" check box to investigate the PATH.
  • Install Git
  • Install GNU Arm Embedded Toolchain and set the install directory to PATH. For example, the path is like "C:\Program Files (x86)\GNU Tools Arm Embedded\9 2019-q4-major".
  • Install MSYS2.
    When the installation is done, "MSYS2 MinGW 64 bit" will run.
  • Run "pacman -Syu"

    $ pacman -Syu
    

  • Close "MSYS2 MinGW 64 bit" to complete installation.
  • Run "MSYS2 MSYS" from start menu and run "pacman -Su" and install development tools.

    $ pacman -Su
    $ pacman -S --needed base-devel mingw-w64-x86_64-toolchain
    

  • Close "MSYS2 MSYS" and run "MSYS2 MinGW 64 bit"
  • Install vim editor and edit .bash_profile to add python path, git path and Arm compiler path.

    $ pacman vim
    $ vim .bash_profile
    

    Add following path setting according to your installed tools version and your folder name.

    PATH="/c/Program Files (x86)/GNU Tools Arm Embedded/9 2019-q4-major/bin":"${PATH}"
    PATH="/c/Users/xxxxx/AppData/Local/Programs/Git/mingw64/bin":"${PATH}"
    PATH="/c/Users/xxxxx/AppData/Local/Prorams/Python/Python310":"${PATH}"
    PATH="/c/Users/xxxxx/AppData/Local/Programs/Python/Python310/Scripts":"${PATH}"
    

  • Close "MSYS2 MinGW 64 bit" and run again.
  • Make a clone of micropython.git in local PC.

    $ git clone https://github.com/micropython/micropython.git
    

  • Build mpy-cross:

    $ make -C mpy-cross
    

  • Update submodules:

    $ cd ports/renesas-ra
    $ make submodules
    

  • Build MicroPython for RENESAS-RA:

    $ cd ports/renesas-ra
    $ ./build_all_boards.sh
    

    or

    $ cd ports/renesas-ra
    $ make BOARD=RA6M2_EK clean
    $ make BOARD=RA6M2_EK
    $ make BOARD=RA6M1_EK clean
    $ make BOARD=RA6M1_EK
    $ make BOARD=RA4W1_EK clean
    $ make BOARD=RA4W1_EK
    $ make BOARD=RA4M1_EK clean
    $ make BOARD=RA4M1_EK
    $ make BOARD=RA4M1_CLICKER clean
    $ make BOARD=RA4M1_CLICKER
    

    If you want to debug the program, please add DEBUG=1. For example in case of RA6M2_EK board as below.

    $ make DEBUG=1 BOARD=RA6M2_EK
    

  • Hex files of MicroPython for RA are generated in the following folder in ports/renesas-ra. You can program this firmware.hex to the target board.

    build-RA4M1_CLICKER/firmware.hex
    build-RA4M1_EK/firmware.hex
    build-RA4W1_EK/firmware.hex
    build-RA6M1_EK/firmware.hex
    build-RA6M2_EK/firmware.hex
