I am beginning to integrate SPI flash support into DSPS sample source base. Our custom application requires flash read/write by the MCU after it has completely booted and running. What is the approach as I am not familiar to the Basic Kit HW?
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. Is there a doc that describes SPI flash and what are the associated registers to set it up for read/wrrite?
2. How do I add the spi.c and spi_flash.c driver to the DSPS project? I know all board drivers exist under sdk/platform/driver.
Thanks,

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？
Does this UM-B-014 document still valid for today's basic kit?
Thanks,

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，
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previous post about running the spi_flash sample code above resulted in everything 0s when reading flash. I believe the program created an array of 512 elements initialized it to (0...511) and write to flash and then read back. If the Basic Kit has flash on the main board, the read back should be valid. Please help...
Thanks,

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。
