預期目標
-------
- 實際體驗 STM32 硬體操作
- 以 `STM32F4-Discovery<http://www.st.com/internet/evalboard/product/252419.jsp>`_ 為參考硬體，探討相關的軟體開發工具與流程
- Unit Test 概念的落實


開發工具介紹與準備
----------------
- GNU Toolchain: 同之前 Lab
- ICE = In-Circuit Emulator
- `Remote Debugging using GDB<http://www.codeproject.com/Articles/14983/Remote-Debugging-using-GDB>`_

.. code-block:: prettyprint

    sudo apt-get install automake* libusb-1.0-0-dev
    git clone https://github.com/texane/stlink.git
    cd stlink
    ./autogen.sh
    ./configure
    make
    sudo cp 49-stlinkv2.rules /etc/udev/rules.d/

- 安裝必要的 Ubuntu 套件

.. code-block:: prettyprint

    sudo apt-get install libjim-dev

- 取得 OpenOCD 原始程式碼

.. code-block:: prettyprint

    git clone git://openocd.git.sourceforge.net/gitroot/openocd/openocd

  * 或者 `openocd-d2f61e1a4592449188305164b27f495f78dca00a.tar.bz2</embedded/Lab6/openocd-d2f61e1a4592449188305164b27f495f78dca00a.tar.bz2>`_

- 編譯 OpenOCD

.. code-block:: prettyprint

    cd openocd
    export SKIP_SUBMODULE=1
    mkdir -p jimtcl
    ./bootstrap
    ./configure --prefix=/opt/openocd \
        --enable-jlink \
        --enable-amtjtagaccel \
        --enable-buspirate \
        --enable-stlink \
        --disable-libftdi \
        --disable-internal-jimtcl
    echo -e "all:\ninstall:" > doc/Makefile
    make
    sudo make install
