通过Python脚本自动配置STM32从SDRAM上运行_stm32调用pytthon脚本-优快云博客

之前写过一篇文章《STM32（在F051上调试通过）配置从SDRAM上启动》https://mp.youkuaiyun.com/mp_blog/creation/editor/127169382，参考该文章可以手工配置从SDRAM上运行程序，但是学习过程中配置起来有些麻烦，每次需要一项项修改一些数据，而且还需要手工计算SDRAM的大小分配，挺麻烦的。开发板的配套光盘都是从Flash上运行，每次学习调试都需要重新配置。希望可以自动配置从Flash还是从SDRAM上运行程序。猜想Keil的工程配置应该在会以文本的方式保存下来，直接修改配置文件应该能达到效果。

经过修改配置，用Beyond Compare工具比对修改前后的文件夹，终于找到了相关配置项保存的位置。main.uvproj和main.uvopt这两个XML文件都会保存，而且有些恶心的是有些配置修改后两个文件都有保存，经过N次尝试后，终于都找到相关配置了。

本程序使用Python实现，通过xml.dom.minidom库修改XML文件，本人第一次使用这个库，不怎么会用，也没那么多时间去查资料，写的代码比较水，勉强能用，需要的可以自己更新。

使用说明，配置如下三个选项即可

SizeInfoStr是KEIL的编译结果内容拷贝
XMLFilePath1：工程文件路径
DownLoadRunConfig ：配置 从SDRAM上还是Flash上运行

主要工作量是在找到配置文件修改点，代码很简单自己查看，总体思路：解析编译结果，计算SDRAM分配，解析XML，修改XML，保存文件，计算SDRAM的时候先优先按整K字节分配，满足不了才使用精确字节数分配

直接上代码了，随便拷贝
