IAR版本不兼容导致无法正常打开工程文件

嵌入式开发/学习过程中，难免需要借鉴别人的工程，但是开发环境的匹配始终是个问题==版本不匹配—无法正常的打开工程文件。 一般官方标配的开发环境包括：

broken options: unknown tool: 打开工程后的一堆messages： LOAD: Configuration ‘FLASH_512KB’ in the project ‘ceac-k60-adc’ contains broken options for tool ‘ICCARM’: (Registry: unknown name: CCOptimizationNoSizeConstraints) Options for ‘ICCARM’ will be set to default.

IAR工程所有的配置都采用的脚本的方式进行描述， 描述工程的三个文件： - IAP.eww–IAR EWARM工作区文件,描述工作区中包含那些project; - IAP.ewp–C-SPY调试器项目设置文件; - IAP.ewd–IAR EWARM项目文件,有关项目的配置信息全在里面;

这里关注IAP.ewp文件，脚本结构是这样子(使用Notepad++文本编辑器)： 找到ICCARM关键字的setting段，此为IAR开发环境相关的。

如何查看找到的 IAR工程文件版本？ 如下图： 正常来说这样子可以看到上次工程被保存时的IAR版本，但实测并没有什么卵用(手动改了便是改了，不更新==不完全可信)。

一堆告警+error，打开options 关注下边图示的内容：

芯片型号选择： 工程内的宏定义： 文件路径包含：

至此，版本兼容的事儿，完全解决，，，

对于IAR 6.5以后的版本，由于IAR开始集成了CORTEX-M3的C文件，因此可以会跟st官方的core_m3.c冲突，解决的办法就是移除官方的该文件，然后在iar的库定义里面添加cm3库。 可能的设置选项在这里： 如使用IAR环境自带的内核文件，勾选上它。
