问题描述
我正在学习STM32裸机编程，在该任务中，我正在使用STM32F429ZI MCU。我在互联网上阅读了很多示例，并且所有示例仅使用一个链接描述文件。我在想，如果这些示例适合我的MCU，那么链接器脚本将与STM32CubeIDE在功能（？）上生成的脚本相同。
现在是我的问题，当我使用STM32CubeIDE生成项目时，我得到了两个链接描述文件STM32F429ZITX_FLASH.ld和STM32F429ZITX_RAM.ld，但是当我检查构建日志时，只有一个链接描述文件。使用STM32F429ZITX_FLASH.ld。 STM32CubeIDE是否使用一个或两个链接描述文件来构建项目？如果仅使用一个，那么为什么会生成两个链接描述文件？
下面，我发布了构建日志。这是我在构建日志中找到的命令：

解决方法
STM32CubeIDE是否使用一个或两个链接描述文件来构建项目？
一个。
为什么STM32CubeIDE有2个生成的链接描述文件？
如果仅使用一个，那么为什么会生成两个链接描述文件？
如果您想从RAM中执行（主要是为了调试）程序，则可以使用第二个链接描述文件，该脚本仅将.data放在RAM中。 CubeMX生成两个链接描述文件，以便您在需要时可以使用第二个。
