如何连接SPI Flash ROM和MicroBlaze

连接SPI闪存ROM有两种选择：
1. MicroBlaze bit-bang
2.传统的HW SPI接口，具有MicroBlaze的字节级或字级接口。
如果你真的想去bit-bang路线，只需搜索“SPI PicoBlaze”。
Picoblaze的XAPP参考设计之一是一个比特式的SPI接口。

阅读手册或用户指南。
你读过手册了吗？
你能找到手册吗？2。
搜索论坛（并搜索网页）以寻找类似的主题。
不要在多个论坛上发布相同的问题。
不要在别人的主题上发布新主题或问题，开始新的主题！5。
学生：复制代码与学习设计不同.6“它不起作用”不是一个可以回答的问题。
提供有用的详细信息（请与网页，数据表链接）.7。
您的代码中的评论不需要支付额外费用。
我没有支付论坛帖子的费用。
如果我写一篇好文章，那么我一无所获。



以下为原文

You have two choices for interfacing to SPI flash ROM:
1.  MicroBlaze bit-bang
2.  Conventional HW SPI interface, with byte-level or word-level interface to MicroBlaze.
 
If you really want to go the bit-bang route, just search for "SPI PicoBlaze".  One of the XAPP reference designs for Picoblaze is a bit-bang SPI interface.

Summary:
1. Read the manual or user guide.  Have you read the manual? Can you find the manual?
2. Search the forums (and search the web) for similar topics.
3. Do not post the same question on multiple forums.
4. Do not post a new topic or question on someone else's thread, start a new thread!
5. Students: Copying code is not the same as learning to design.
6 "It does not work" is not a question which can be answered. Provide useful details (with webpage, datasheet links, please).
7. You are not charged extra fees for comments in your code.
8. I am not paid for forum posts.  If I write a good post, then I have been good for nothing.

你有开发板吗？
Base System Builder将为您连接SPI Flash。
我怀疑任何开发者。
使用SPI Flash的电路板将向您展示如何在该电路板的Intro to MicroBlaze教程中使用。

Do you have a development board?  Base System Builder will connect a SPI Flash for you.  I suspect any dev. board with SPI Flash will show you how in the Intro to MicroBlaze tutorial for that board.

我使用Digilent Atlys板。
到目前为止我看不到任何教程。
谢谢。

I use Digilent Atlys board. I couldn't see any tutorial so far.
 
Thanks.

嗨，
我会运行digilent网站上提供的Atlys参考设计（在XPS 12.x下使用）。
通过这种方式，您已经确定必须进行良好的系统组装。
（可能您可能希望删除UCF文件中的TEMAC实例及其所有端口...如果您没有TEMAC许可证）。
我还看到digilent使用他们自己的IP内核用于SPI，并且还添加了一个小代码来测试SPI ......所以这应该可以解决，我想。

以下为原文

Hi,
 
I would run the Atlys reference design provided on the digilent website (to use under XPS 12.x).  In that way you are already sure to have to good system assembly.  (probably you might want delete the TEMAC instance and all its ports in the UCF file... if you dont have the license for TEMAC).
I also saw that digilent uses their own IP core for the SPI  and there is also a small code that added that will test the SPI ... so this should work out OK I think.

您想将SPI存储器用作通用数据存储器还是用于微型程序？
----------------------------是的，我这样做是为了谋生。

Do you want to use the SPI memory as general-purpose data storage, or for the micro's program?
 
----------------------------Yes, I do this for a living.

作为第一步，我想学习如何进行通用数据传输，然后我希望我的代码从SPI闪存运行。
谢谢。

As a first step, I want to learn how to do general-purpose data transfer, then I want my code to run from SPI flash memory.
 
Thank you.
