在dsp外围代码库中添加SPI Flash支持

首先，我真的很欣赏到目前为止我收到的令人敬畏的发展支持。你们是一个伟大的令人敬畏的团体，并且具有这种客户焦点，公司绝对是正确的。雷电竞下载app

我开始将spiflash支持集成到DSPS示例源代码库中。我们的自定义应用程序需要在MCU完全启动和运行后进行闪存读/写。由于我对基本套件硬件不熟悉，采用什么方法？

只需查看两个项目的user_periph_setup.c，periph_init（）中存在一些重叠行。我的问题是：

1是否有描述SPI闪存的文档，以及为读/写设置的相关寄存器是什么？
2如何将spi.c和spi\u flash.c驱动程序添加到DSPS项目中？我知道所有的单板驱动程序都在sdk/platform/driver下。

谢谢，

我把spi\ U闪光灯调干了

测试结束

在检查UM-B-014文档后，我将实现580个基本套件没有闪存的闪存。我不确定这是否是真的，因为文件非常陈旧，因为它描述了一个具有JTAG加密狗，运营板和女儿卡等的旧14580个开发套件。

然后它包装一个问题，这是我在板上闪光的基本套件？
这个UM-B-014文件对今天的基本套件仍然有效吗？

谢谢，

如果580基本套件没有

如果580个基本套件没有闪存在板上，那么我将如何使用SmartSnippet，然后单击SPI闪存按钮以将DSP FW上传到闪存，并且还能够在写入之前擦除闪光灯？请帮我拉直事物。

嗨凯海，

嗨凯海，

UM-B-014是指我们推出DA14580的orignial套件的专家套件：从那时起，我们已经使用了基本的套件和Pro套件。基本套件/专业套件在主板上有闪光灯设备，而专家套件则不会。

查看以下应用程序注释.N-B-023介绍如何接口外部存储器（例如SPI Flash）。这涵盖了基本和Pro套件的选项，它应该在您的方式上帮助您，并向您展示如何为SPI闪存访问SDK5中的API。

https://support.dialog-semiconductor.com/resource/b-023-interfacing-da14...

此外，下面的软件开发指南的第10.10节将向您展示如何使用SPI闪存驱动程序。

如果你可以引用我的

如果你可以参考我之前的文章，关于运行上面的spi\u flash示例代码，在读取flash时会导致一切0。我相信这个程序创建了一个由512个元素组成的数组，将其初始化为（0…511），然后写入flash，然后再读回。如果基本套件在主板上有闪存，则读回应该是有效的。请帮忙。。。

谢谢，

嗨kqtrinh，

嗨kqtrinh，

基本套件在船上有一个闪光灯，但您需要通过相应的跳线连接它，您完成了吗？在基本套件上，只是J4标题后面有一个示意图，描述了应该进行的连接，以便在闪存上操作基本套件。

谢谢你的对话
