1. 系统准备

1.1 OS

操心系统：ubuntu-16.04.2-desktop-amd64 或ubuntu-14.04.x-desktop-amd64

1.2 安装pip

$ sudo apt install python-pip

把pip更新到最新：

$ sudo pip install --upgrade pip

1.3 安装Python及多个版本的使用

此步骤为可选 安装2.7和3.4两个版本：

sudo apt-get install python2.7
sudo apt-get install python3.4

切换python版本，在终端输入以下命令：

$ ls -larth `which python`*
-rwxr-xr-x 1 root root  306  2月 20  2014 /usr/bin/pythontex3
lrwxrwxrwx 1 root root   58  2月 20  2014 /usr/bin/pythontex -> ../share/texlive/texmf-dist/scripts/pythontex/pythontex.py
lrwxrwxrwx 1 root root    9  5月 10  2017 /usr/bin/python2 -> python2.7
lrwxrwxrwx 1 root root    9  5月 10  2017 /usr/bin/python -> python2.7
lrwxrwxrwx 1 root root    9  5月 10  2017 /usr/bin/python3 -> python3.4
lrwxrwxrwx 1 root root   10  5月 10  2017 /usr/bin/python3m -> python3.4m
-rwxr-xr-x 1 root root 3.2M 11月 24  2017 /usr/bin/python2.7
-rwxr-xr-x 2 root root 3.6M 11月 29  2017 /usr/bin/python3.4m
-rwxr-xr-x 2 root root 3.6M 11月 29  2017 /usr/bin/python3.4

$ sudo update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1
$ sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.4 2

$ sudo update-alternatives --config pythonThere are 2 choices for the alternative python (providing /usr/bin/python).

  Selection    Path                Priority   Status
------------------------------------------------------------
* 0            /usr/bin/python3.4   2         auto mode
  1            /usr/bin/python2.7   1         manual mode
  2            /usr/bin/python3.4   2         manual mode

Press enter to keep the current choice[*], or type selection number: 

根据出现的序号，选择你需要的python版本，输入序号回车即可。

如果使用python3.4，则还需要安装pip3:

$ sudo apt-get install pip3

2. 安装JDK

JDK下载 jdk-8u181-linux-x64.tar.gz

$ sudo tar zxvf jdk-8u181-linux-x64.tar.gz  -C /opt
$ vi ~/.bashrc

export JAVA_HOME=/opt/jdk1.8.0_181
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib 
export PATH=${JAVA_HOME}/bin:$PATH

3. 安装Toolchain

Download URL:

https://github.com/gnu-mcu-eclipse/arm-none-eabi-gcc/releases/download/v7.3.1-1.1/gnu-mcu-eclipse-arm-none-eabi-gcc-7.3.1-1.1-20180724-0637-centos64.tgz

下载最新版：gnu-mcu-eclipse-arm-none-eabi-gcc-7.3.1-1.1-20180724-0637-centos64.tgz

mkdir ~/opt
$ tar -zxvf gnu-mcu-eclipse-arm-none-eabi-gcc-7.3.1-1.1-20180724-0637-centos64.tgz -C ~/opt/

注意：不需要将工具链路径添加到用户或系统路径！

如果现有一个工具链只有一个单一版本，那么这不会有问题，但如果有相同工具链的多个版本，将会出现问题。所以不设置工具链路径，由GNU MCU Eclipse插件管理工具链。

4. 安装SEGGER J-Link

J-Link download URL: https://www.segger.com/downloads/jlink/

下载该特定版本：JLink_Linux_V612e_x86_64.tgz。 注意：不可下载最新版！

安装：

$ sudo mkdir /opt/SEGGER
$ sudo tar -zxvf JLink_Linux_V612e_x86_64.tgz -C /opt/SEGGER/
$ sudo cp /opt/SEGGER/JLink_Linux_V612e_x86_64/99-jlink.rules /etc/udev/rules.d/

$ vi ~/.bashrc

export JLINK_HOME=/opt/SEGGER/JLink_Linux_V612e_x86_64
export PATH=${PATH}:${JAVA_HOME}/bin:${JLINK_HOME}

测试：

通过JLink连接PC到开发板。
执行命令：

$ JLinkExe

5. eclipse安装及配置

5.1. 安装eclipse

最简单的方法是从GNU MCU Eclipse GitHub Release下载，可以同时获得Eclipse CDT和MCU所需的插件。

gnumcueclipse-4.4.1 下载

下载的压缩包为20180721-1240-gnumcueclipse-4.4.1-oxygen-3a-linux.gtk.x86_64.tar.gz。

tar zxvf 20180721-1240-gnumcueclipse-4.4.1-oxygen-3a-linux.gtk.x86_64.tar.gz -C ~/opt/
$ sudo vi /usr/share/applications/eclipse.desktop

[Desktop Entry]
Name=Eclipse
Type=Application
Exec=/home/username/opt/eclipse/eclipse
Terminal=false
Icon=/home/username/opt/eclipse/icon.xpm
Comment=Integrated Development Environment
NoDisplay=false
Categories=Development;IDE;
Name[en]=Eclipse

$ sudo chmod u+x /usr/share/applications/eclipse.desktop
$ ln -sf $JRE_HOME ~/opt/eclipse/jre

than, launch eclipse.

5.2. 配置Toolchain和J-Link路径

Eclipse menu –> Window –> Preferences
MCU –> Global ARM Toolchains Paths Default toolchain: GNU MCU Eclipse ARM Embedded GCC Toolchain name: GNU MCU Eclipse ARM Embedded GCC Toolchain folder: /home/username/opt/gnu-mcu-eclipse/arm-none-eabi-gcc/7.3.1-1.1-20180724-0637/bin
MCU –> Global SEGGER J-Link Path Executable: JLinkGDBServer Folder: /opt/SEGGER/JLink_Linux_V612e_x86_64
MCU –> Workspace ARM Toolchains Paths Default toolchain: GNU MCU Eclipse ARM Embedded GCC Toolchain name: GNU MCU Eclipse ARM Embedded GCC Toolchain folder: /home/username/opt/gnu-mcu-eclipse/arm-none-eabi-gcc/7.3.1-1.1-20180724-0637/bin
MCU –> Workspace SEGGER J-Link Path Executable: JLinkGDBServer Folder: /opt/SEGGER/JLink_Linux_V612e_x86_64
Apply and Close

6. 安装工作区偏好设置

6.1. 自动保存和文本文件编码

如果编辑了代码忘记了保存，编译运行后是没有任何变化的，所以最好设置自动保存。

go to the Eclipse menu → (Windows →) Preferences → General → Workspace
enable Save automatically before build

在同个页面，设置文本编码和行分隔符：

in the Text file encoding section
click the Other button
select UTF-8 in the combo box
check the New text file line delimiter to be set to Unix
disable the Build automatically option
last, click the Apply button

6.2. 显示行号

go to the Eclipse menu → (Window →) Preferences → General → Editors → Text Editors
enable Show line numbers
enable Show print margin
set the Print margin column at 80
click the Apply button

6.3. 使用活动构建配置进行索引

Eclipse CDT有一个非常强大的索引器，它可以动态解析源代码，并在编辑时提供提示，自动完成帮助，错误报告等，而无需启动构建过程。要使索引器在从一个配置更改为另一个配置时自动同步，请检查索引器是否设置为使用活动配置：

go to the Eclipse menu → (Window →) Preferences → C/C++ → Indexer
enable Use active build configuration
click the Apply button

6.4. 编辑器折叠

为了更好地查看源文件的整个内容，建议禁用编辑器折叠：

go to the Eclipse menu → (Window →) Preferences → C/C++ → Editor → Folding
disable Header Comments (in fact it is recommended to disable all foldings)
click the Apply button

6.5. 代码格式

Eclipse CDT具有非常有用的功能，允许自动重新格式化一段代码以符合给定的样式。推荐的样式是GNU：

go to the Eclipse menu → (Window →) Preferences → C/C++ → Code Style → Formatter
in the Active profile: field, select GNU [built-in]
click the Edit… button
set Profile name to GNU with spaces
Change the tab policy to Spaces only, and the indentation and tab size to 2

6.6. 编译控制台

go to the Eclipse menu → (Window →) Preferences → C/C++ → Build → Console
enable Wrap lines on the console
enable Bring console to top when building
increase the Limit console output: field, for example from 500 to 5000 lines
click the Apply button

6.7. Doxygen

To enable support for documentation tool comments:

go to the Eclipse menu → (Window →) Preferences → C/C++ → Editor
select Doxygen in the Documentation tool comments 这样，你只需输入/**，剩余的注释会自动补齐。

6.8. 调试前面应用

Eclipse会记住以前使用的调试配置，并可将其作为主调试按钮的默认配置。

go to the Eclipse menu → (Window →) Preferences → Run/Debug → Launching
select Always launch the previously launched application in the Launch Operation section.

6.9. Show source roots

对于具有许多源文件夹的大型项目，您可能希望禁用显示源文件夹：

go to the Eclipse menu → (Window →) Preferences → C/C++ → Appearance
disable Show source roots at top of project.

7. Create a Hello ARM test project

7.1 Create and Build

go to Eclipse menu, File –> New, and select the C Project
In the C Project window, set Project name = hello, Project type = Executable –> Hello World ARM Cortex-M C/C++ Project
Toolchains: Cross ARM GCC
click the Next-> button

In the Target processor settings:

In the Folders:

In the Select Configurations:

In the GNU ARM Cross Toolchain:

click the Finish button.
Modify as the following and build the hello project.

7.2 Debug

go to Eclipse menu, **Run –> Debug Configurations… **
Double click GDB SEGGER J-Link Debugging and config as following:
click the Debug button

7.3. 创建一个具体实例

参见7.1，创建工程 CM4Template，目录结构如下：

CM4Template

    DebugMon_Handler,
    0,                          // Reserved
    PendSV_Handler,             // The OS context switch interrupt
    SysTick_Handler,            // The OS timer
    0,
    }
};

main.c

#include <stdio.h>
#include <stdlib.h>

int
main (void)
{
  return 0;
}

之后，编译，debug，主要，在从RAM运行程序时，disable the Pre-run reset and halt option in the Startup tab
