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
• 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

Programming STM32 F2, F4 ARMs under Linux

• A Tutorial from Scratch<http://www.triplespark.net/elec/pdev/arm/stm32.html>_
  • Introduction STM32, STM32F2, STM32F4
  • Obtaining and Setting Up OpenOCD
  • Setting up the Hardware: STM32F4Discovery with integrated ST-Link/V2
  • The Minimalistic Hello-World Program
  • Running the Minimalistic Hello-World Program

• 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
• Neocon 離開方法: ~. -> exit
  • neocon /dev/ttyACM0

作業

• 透過 OpenOCD 對 STM32F4Discovery 內建的 ST-Link/V2 介面，設計一個驗證硬體的 unit test 環境
• 藉由 OpenOCD + GDB，實做 firmware download 程式，可視為 boot loader
• 一旦系統藉由特製的 boot loader 載入於 STM32F4-Discovery 硬體並啟動後，可監控系統運作並執行特定的 unit test 程式
