【原创】一步一步学ZedBoard & Zynq(六)：在ZedBoard上运行linux并编写linux下的应用程序HelloWorld

开发环境：Windows XP 32 bit

development environment: Windows XP 32 bit

软件： SDK 14.2

Software: SDK 14.2

一、获取Zedboard可运行的linux

i. Get Zedboard running linux

Digilent官网给出Zedboard的可运行linux设计ZedBoard_OOB_Design包，可从http://www.digilentinc.com/Data/Documents/Other/ZedBoard_OOB_Design.zip获取，下载后解压，可以看到包的结构和内容：

Digilent Network gives Zedboard's runable linux design ZedBoard_OB_Design package, available from http://www.digilentinc.com/Data/Documents/Other/ZedBoard_OB_Design.zip, downloading and unpressureing the package's structure and content:

boot_image目录:
-- system.bit – 配置FPGA的bit文件
-- u-boot.elf – 引导linux需要的Second-Stage boot loader
-- zynq_fsbl.elf – 配置ARM PS系统的First-Stage boot loader(FSBL)

boot_image directory:
-- system.bit - configuration of FPGA bit files
- - guiding Linux needs Second-Stage Boot loter
- zynq_fsbl.elf - configuration of ARM PS systems

doc目录:
-- README.txt – 说明文件

directory:
--t-descript document

hw目录:
-- EDK 14.1版本的XPS工程，用来生成硬件文件和bit文件

hw directory:
-- EDK 14.1 version of XPS project to generate hardware and bit files

linux目录:
-- devicetree_ramdisk.dts – 设备树源代码
-- .config – Linux内核配置文件，用来生成zImage

linux table of contents:
-- - device tree code
-- - Linux core configuration file to generate zIagemm

sd_image目录:
-- BOOT.BIN – 使用boot_images中的三个文件生成的Zynq配置文件
-- devicetree_ramdisk.dtb – 编译后的设备树文件
-- ramdisk8M.image.gz – 编译后的文件系统
-- README – 介绍如何运行OOB设计的说明文档
-- zImage – 编译后的内核

sd_image catalogue:
-- - Zynq configuration file
-- sw目录:
--硬件配置
--FSBL源代码

sw directory:
- hardware configuration
- FSBL source code

Zedboard的连接和短路块设置

上电后，等待ARM PS的配置、FPGA的配置(蓝色LED DONE 亮起)，之后开始引导Linux系统了。可以从超级终端上看到一系列的引导信息：

After powering, waiting for the ARM PS configuration, the FPGA configuration (blue LED Done) and then starting to direct Linux. You can see a series of guidance messages from the super terminal:

至此，linux已经在Zedboard上启动起来。从超级终端输出的信息我们打开可以知道，“这个”linux系统的一些基本情况，如8~10行

So, linux has been activated on Zedboard. We open information from the super terminal and we can see some basics of the "this" linux system, such as 8-10 lines.

In:    serial
Out:   serial
Err:   serial

输入输出调试信息使用的都是serial，即串口，这里是超级终端，因而超级终端就如同linux系统下的控制台，我们可以键入linux的命令对系统进行操作，例如输入ls命令，可以显示当前目录内容：

The output debugging information is used by the serial, the serial port, which is the super terminal, so the super terminal is like a control table under the linux system, and we can type linux commands to operate the system, such as input ls commands, and display the current directory content:

其他命令如cd、mkdir、cp、rm等基本命令均可以执行。

Other basic orders, such as cd, mkdir, cp, rm, are enforceable.

77~79行提示信息

Information for line 77 ~ 79

[    0.270000] CPU1: Booted secondary processor
[    0.310000] CPU1: thread -1, cpu 1, socket 0, mpidr 80000001
[    0.310000] Brought up 2 CPUs

可以知道ARM PS的两个CPU均被启动

You can see that both ARM PS CPUs have been activated.

再如163~171行

Like 163-171 lines.

可以知道大容量USB设备驱动已经安装，包括PS USB设备等驱动均安装了，因此可以使用U盘、USB键盘、鼠标、摄像头等设备。

It is known that large-capacity USB drivers have been installed, including PS USB devices, so that equipment such as U Disk, USB keyboards, mouse, camera etc. can be used.

二、使用SDK设计linux应用程序

ii. Use of SDK design linux applications

接下来我们就可以像其他的嵌入式linux开发一样来使用Zedboard了。SDK提供了标准可视化的linux-arm交叉编译链，不需要再进行交叉编译环境的搭建。

And then we can use Zedboard like any other embedded linux development. SDK provides a standard linux-arm cross-editing chain, and there is no need for cross-editing.

启动SDK，new->C project，选择工程类型为“Xilinx ARM Linux Executable”，工具链为“Xilinx ARM GNU/Linux Toolchain”

Start SDK, new->C project, select project type "Xilinx ARM Linux Exportable" and tool chain "Xilinx ARM GNU/ Linux Toolchain"

在工程配置选项中，去掉Debug(因为我们不需要进行调试)，只保留Release

In the scope configuration option, delete Debug (because we don't need to debug) and keep Release

工程建立后好，新建main.c文件，修改内容如下：

When the project was established, a new main.c document was created, with the following modifications:

1
7
8 #include <stdio.h>
9
10 int main()
11 {
12     printf("HelloWorld! ");
13     printf("This is from Zedboard Linux! ");
14     printf("2012年11月8日16:43:22 by 超群天晴 ");
15     return 0;
16 }

"collor: #0080;" >8; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; """"""""""""""[s/[s/[s)""""""[s"[s""""s"s"""""s"s"s"s"s"s<[s"s"s"s"s"s"s"s"s"s"s

就是一个简单的从控制台输出helloworld信息。编译后生成了lab_6.elf可执行文件，将其拷贝到了U盘上。

This is a simple output of helloworld information from the control table. A lab_6.elf executable was created and copied to the flash drive.

三、运行linux可执行程序

Operational linux executables

将U盘连接到Zedboard，控制台会提示有USB device连接上，分配给这个设备的名称是sda1

Connect the flash drive to Zedboard, and the controller will alert us to the USB link, which is assigned to this device by the name of sda1

使用mount命令

Use Mount Command

mount /dev/sda1 /mnt/

将设备挂载到mnt目录下，

Mount the device to the mnt directory,

 输入命令

& nbsp; input command

 cd /mnt

 切换到mnt目录

& nbsp; Switching to mnt directory

输入命令

Enter Command

 ls

可以看到目录下有我们刚刚生成的lab_6.elf可执行文件
