使用EclipseCDT搭建Beaglebone Linux开发环境

操作系统, Linux, Black, 开发, 记录

今天看了很久 Derek Molly的视频https://www.youtube.com/watch?v= ... =PLF4A1A7E09E5E260A，最后终于成功搭建好Beaglebone Linux的开发环境，在此记录一下。
我的主机环境： Ubuntu 12.04+Eclipse （Kepler Service Release 1），开发板是Beaglebone Black，开发板的操作系统是 Angstrom v2012.12
先说一句，通过ssh远程登陆到Beaglebone中，通过安装g++（opkg install g++）也是可以开发的，但是调试时未免麻烦。

下面进入正题：
首先下载Eclipse + CDT plugin，现在可以直接下载集成好的，下载地址为http://www.eclipse.org/downloads ... evelopers/keplersr1 ，打开链接后在页面右侧有Download Link，可以根据自己的操作系统进行选择，我的是 Linux 64bit。
下载好之后直接解压就可以使用了（起码Linux是这样），无需安装。
为了能够更方便地通过PC来查看、操作Beaglebone，以及更加方便地调试，需要安装另外一个插件， RSE-runtime。打开Eclipse之后，依次选择Help -&gt; Install new software, 在弹出来的对话框里的第一个输入框里输入Kepler - http://download.eclipse.org/releases/kepler，之后Eclipse会联网下载可更新软件目录，下载目录完成后，对话框的中间会有很多插件可供安装，点击 Mobile and Device Development 前面的小三角，在展开的目录项中勾选&nbsp; &nbsp; Remote System Explorer End-User Runtime，然后按照提示即可安装完成。如下图所示：

接着来验证一下是否顺利安装成功了。要先确保安装好Linux操作系统的Beaglebone Black和计算机已经可靠连接。回到Eclipse主界面，选择 Window -&gt; Show View -&gt; Other, 弹出的对话框中选择 Remote System，点击OK。Remote System的窗口就会显示在界面的下方，可以根据需要把这个窗口拖放的自己喜欢的位置，我把它拖到了界面的左侧，和Project Explorer处于同一位置。&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; a. 在Remote System 窗口中右击，然后选择New -&gt; Connection, 弹出如下图所示的对话框

&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; b. 选择Linux，单击Next。
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; c. 然后，按照下图进行设置：
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; 其中Host Name填写BeagleboneBlack的IP地址，第二条会自动填写。Description可以任意填写一个自己喜欢用的名字。
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; 点击Next。
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; d. 勾选Configuration中的ssh.files,点击Next:
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; e. 勾选Configuration中的processes.linux.shell,点击Next:
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;
&nbsp; &nbsp;&nbsp; &nbsp;
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; f. 勾选Configuration中的ssh.linux,点击Finish:
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;g. 右击Ssh Terminals, 选择Connect，在弹出的对话框中填写Beaglebone Black 上Linux中的用户名和密码，就可以登陆了。右击Ssh Terminal，选择Launch Terminal，可以在下方的窗口中看到Terminal，这样，就已经远程登陆到Linux中了。试一试，可以交互：
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;
5. 下面编写一个C++程序控制Beaglebone Black上4个User LED的亮灭（这里先以控制一个为例）：
新建一个C++ Project
源程序为#include &lt;iostream&gt;#include &lt;stdio.h&gt;using namespace std;int main() {&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;cout &lt;&lt; &quot;LED 1 starts flashing&quot; &lt;&lt; endl;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;FILE *LEDHandle = NULL;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;char *LED1Brightness = &quot;/sys/class/leds/beaglebone:green:usr1/brightness&quot;;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;for(int i=0; i&lt;10; i++)&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;{&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; if((LEDHandle=fopen(LED1Brightness, &quot;r+&quot;))!=NULL)&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; {&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;fwrite(&quot;1&quot;, sizeof(char), 1, LEDHandle);&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;sleep(1);&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;fclose(LEDHandle);&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; }&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; if((LEDHandle=fopen(LED1Brightness, &quot;r+&quot;))!=NULL)&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; {&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;fwrite(&quot;0&quot;, sizeof(char), 1, LEDHandle);&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;sleep(1);&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;fclose(LEDHandle);&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; }&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;}&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;cout &lt;&lt; &quot;LED 1 ends flashing&quot; &lt;&lt; endl;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;return 0;}
