我想问下关于STM32F107 RAM调试的问题 [复制链接]

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。

RAM中进不了中断还缺以下两步：

tyc119514155

请问，我是把你指出的，中断向量函数直接添加到main 里面吗？
除了你说的那步，我要在RAM中调试还有哪些设置的问题吗？
我的以上设置应该不会错吧，帮忙回答下，谢谢。

funnylogic

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

tyc119514155

我的RAM.INI是这样的


FUNC void Setup (void) {
  SP = _RDWORD(0x20000000);          // Setup Stack Pointer
  PC = _RDWORD(0x20000004);          // Setup Program Counter
  _WDWORD(0xE000ED08, 0x20000000);   // Setup Vector Table Offset Register
}

LOAD ..\SRAM\output\TEST.axf INCREMENTAL      // Download         

Setup();                             // Setup for Running

g, main


你说的“中断向量表” 指的是
void NVIC_Configuration(void)
{
#ifdef  VECT_TAB_RAM  
  /* Set the Vector Table base location at 0x20000000 */
  NVIC_SetVectorTable(NVIC_VectTab_RAM, 0x0);

#else  /* VECT_TAB_FLASH  */
  /* Set the Vector Table base location at 0x08000000 */
  NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x0);   

#endif
}
吗？
