Lab24: Hardware

預期目標

• 學習使用 STM32F4-Discovery 硬體
• 接觸 ARM Cortex-M 環境
• 學習 GNU Toolchain 與相關 open source 工具

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* libtool libusb-1.0-0-dev
git clone http://github.com/texane/stlink.git
cd stlink
./autogen.sh
./configure --prefix=/usr
make
sudo make install
sudo cp 49-stlinkv2.rules /etc/udev/rules.d/

• 取得 OpenOCD 原始程式碼

.. code-block:: prettyprint

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

或者 http://sourceforge.net/projects/openocd/files/openocd/0.7.0/

• 編譯 OpenOCD

.. code-block:: prettyprint

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

工作環境

• 取得最新 Labs 內容 (與之前 Lab3</embedded/Lab3>_ 操作相似)：

.. code-block:: prettyprint

git clone git://gitcafe.com/embedded2012/Labs.git
cd Labs/Lab-6

或是

.. code-block:: prettyprint

cd Labs/Lab-6
git fetch labs
git merge labs/master HEAD

具備互動操作的 USB serial 實做

• http://www.sparetimelabs.com/usbcdcacm/ (文末提到與之前指定作業相關的技術議題)
• USB list: /var/lib/usbutils/usb.ids
  • ArchLinux: /usr/share/hwdata/usb.ids
• neocon 離開方法: ~.
  • neocon /dev/ttyACM0
• http://wiki.openmoko.org/wiki/NeoCon
• http://wiki.openmoko.org/wiki/CDC_ACM

示範程式碼

.. code-block:: prettyprint

cd Labs/Lab-6/discoveryF4
make
cd discovery_demo
make flash
cd ../serialUSB/
make flash
