Lab6: Hardware

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

• st-link

  • git clone https://github.com/texane/stlink.git

• Remote Debugging using GDB<http://www.codeproject.com/Articles/14983/Remote-Debugging-using-GDB>_

• sudo apt-get install git automake libusb-1.0-0-dev

• sudo cp 49-stlinkv2.rules /etc/udev/rules.d/

• 安裝必要的 Ubuntu 套件

.. code-block:: prettyprint

sudo apt-get install automake*
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
