Adam Taylor玩转MicroZed系列73:用其他的Zynq-Based的板子来工作

By Adam Taylor

在过去一周中,我接到了很多不同人的来信,他们正在使用以Zynq为基础的开发工具。他们非常想知道怎么样去把MicroZed系列博客教程应用到 他们所选择的硬件平台上。加上Avnet MicroZed有许多其他一些的著名开发工具,这些工具都是基于Zynq版本。以下是一系列著名的Zynq-based开发板,这些开发板展示了 Zynq SoC在每个板子上的变化:

  • MicroZed – XC7Z010
  • ZedBoard – XC7Z020
  • ZC702 – XC7Z020
  • ZC706 – XC7Z045
  • ZYBO – XC7Z010
  • 为什么其他一些硬件工具的使用者不想按照网上非常好的Zynq博客教程走呢?事实上,这是很容易做的。让我们回到十二个月前我们这个系列教程的第一篇博客,在这篇博客里面,我们定义了我们要使用的硬件的配置信息。此时此刻,我们可以申明我们所用的板子和工程,如下图所示:

    选择理想的板子来配置合适的SoC,外围环境和板上外设——比如,每一个外设应该连接到哪一个MIO pins上,连同一些对MIO pins来说需要的配置信息。最重要的是,这个选择也分配了DDR DRAM的地址位置和配置参数,这个避免我们手动输入信息。下图显示了MicroZed DDR的配置信息:

    但是如果我们想用一个默认缺省built的板子该怎么办?在这种情况下,我们可以导入一个xml文件,这个文件中定义了我们打算使用的板子的配置信息。这个文件通常是由板子的制造商提供,如果没有的话,需要有一个。

    导入这些文件之一很简单:

    • 在你的开发板或者开发工具中,创建一个指向目标器件的工程。
    • 创建一个新的框图(如这个系列的第一篇博客所示),然后从IP核库中添加一个新Zynq IP核。
    • 双击框图打开重定制IP核窗口。
    • 选择IMPORT XPS SETTINGS 选项。
    • 指向vendor提供给你的XML文件。

    导入文件如下图所示:

    下图显示了Digilent Zybo板子上zynq的DDR配置:

    一旦你的硬件成功地定义了,你就可以像我在这个系列日志中所做的一样搭建你的系统。我的日志大部分关注使用外设和模块。在这种情况下,不需要有什么 变化。当日志使用外围设备——比如说LEDS或者按键开关——你需要适应MIO规范说明和你板子的输出引脚。但是,博客解释了怎样做这些尽管这些博客主要 关注的是Avnet MicroZed板子。对任何板子,使用这些博客帖子是非常直接了当的,因为它们所用的原则都是一样的。

    你可以在玩转MIcroZed系列博客中找到任何之前例子的代码。之前系列的博客列表如下面所示。

    向那些发邮件问我的朋友们表示致谢!我希望你们在跟着这个系列博客学习Zynq SoC的过程中感到开心。
