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

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
- Debugging
- Automating the Steps
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
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
- 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
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
