Lab32: QEMU + FreeRTOS
預期目標
- 體驗一個具體而微的 MCU 程式開發過程,使用 GNU Toolchain
- 藉由 QEMU 模擬環境,嘗試控制週邊 (STM32 USART) 並觀察其行為
- 接觸 FreeRTOS
預先準備
- 安裝 Ubuntu Linux,建議版本為 14.04
- 安裝必要的套件
.. code-block:: prettyprint
sudo apt-get install git zlib1g-dev libsdl1.2-dev automake* autoconf* libtool libpixman-1-dev
- 若 Ubuntu 使用 64bit 版本 ,請額外安裝 lib32gcc1 之套件
.. code-block:: prettyprint
sudo apt-get install lib32gcc1 lib32ncurses5
- 取得 GNU Toolchain:
toolchain-2012_03.tar.bz2</embedded/Lab1/toolchain-2012_03.tar.bz2>
_ 、保存到 /tmp 目錄,並且解開到系統中,操作如下
.. code-block:: prettyprint
cd /
sudo tar jxvf /tmp/toolchain-2012_03.tar.bz2
- 檢查 Toolchain 是否正確安裝:
ls /usr/local/csl/arm-2012.03/
STM32 Overview
- Powerful but Cheap
- Wireless Connectivity
- Computing/Prototyping
- One for most use cases
