我想问下关于STM32F107 RAM调试的问题

最近，想在RAM中调试代码。
       参考了网上的说法，我使用的是MDK ，环境的设置和进入JLINK 调试如图所示。
       对于RAM.INI文件中的 AXF文件的目录页做了正确的配置。
       有关BOOT1和BOOT0的设置，网上有些说要设置成RAM启动方式 ，有些说可以不用设置。
       BOOT1和BOOT0当我设置成从RAM启动方式时，进入JLINK调试，开发板在“全速调试”和“单步调试”下都运行不起来，LCD显示白屏。
       BOOT1和BOOT0设置成FLSAH 启动方式下，点击”DEBUG“按钮，进入JLINK调试，板卡直接进入“全速运行“，我看汇编窗口程序不是运行在RAM 当中,而且不能进入中断。
        不知道以上的问题哪位高手能帮我解决下。 此帖出自小平头技术问答

中断向量函数可以直接添加在main里面，但一定要在RCC_Configuration()之后执行。还有该对话框中的Reset and Run这个勾要去掉。

RAM.ini文件里还要加上把中断向量表复制到ram里的语句，只初始化ram是不够的

        文件名： ExtSRAM.ini

        这是外部SRAM调试脚本。开始Load程序时，由IDE控制仿真器执行这段脚本程序。

        本脚本完成的功能是
        (1) 配置CPU的FSMC总线，使CPU能够访问外部SRAM，已便于后面装入程序
        (2) 复制外部SRAM的中断向量表（0x130字节）到CPU内部RAM
        (3) 设置堆栈指针SP
        (4) 修改PC指针
       
        注意：工程选项IRAM1的起始地址必须是0x20000200开始

        脚本的语法：
        参加MDK的HELP, 搜索关键字 “uv3 Library Routines” 可以看到uv3支持的脚本命令

这是STM32F103ZET6的在外部ram调试的.ini文件，自己参考一下吧
