Yes, your project seems to be missing the critical startup_stm32f10x.s (or equivalent) file, describing the STM32F1 interrupt vector table. Please review some of the template projects in the firmware libraries, and use those as a guide to setting up your own.

yes. i did not add ''startup_stm32f10x_hd.s'' correctly to my project.

Thanks a lot.

hi

i have new problem with IAR interrupt. i config TIM2 interrupt and after execute: TIM_ITConfig(TIM2, TIM_IT_Update, ENABLE); jtag jump to  ''startup_stm32f10x_hd.s'' and stop in line:           B TIM2_IRQHandler //---- my config and functions: void TIM2_IRQHandler(void)// call 62.5us Timer INT Lable {   if (TIM_GetITStatus(TIM2, TIM_IT_Update) != RESET) // Qualify the source   {     TIM_ClearITPendingBit(TIM2, TIM_IT_Update); // Clear the source   }     if(BufferCounter<(BfrSize-SprtBfrSize))     {         if(BufferCounter==0)             Buffer_Flag=0x01;         DAC_SetDualChannelData(DAC_Align_8b_R,Buffer[BufferCounter],Buffer[BufferCounter]);         BufferCounter++;     }     else     {         if(BufferCounter==(BfrSize-SprtBfrSize))             Buffer_Flag=0x02;         DAC_SetDualChannelData(DAC_Align_8b_R,PBuffer[BufferCounter-(BfrSize-SprtBfrSize)],PBuffer[BufferCounter-(BfrSize-SprtBfrSize)]);         BufferCounter++;         if(BufferCounter>=BfrSize)             BufferCounter=0;     } } //----------------------------------     RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE);// TIMER2 CLOCK ENABLE     RCC_APB1PeriphResetCmd(RCC_APB1Periph_TIM2,DISABLE);       NVIC_InitStructure.NVIC_IRQChannel = TIM2_IRQn;      // Define the INT source     NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 7;// Define the INT Priority     NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;         NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;// Enable and Run the Timer     NVIC_Init(&NVIC_InitStructure); //------------------- void TIM_Configuration(void)// Timer Config for 10us {     TIM_TimeBaseInitTypeDef  TIM_TimeBaseStructure;     TIM_TimeBaseStructure.TIM_Period = 4500;//4500  => 62.5us // Timer count to TIM_Period and will be Reset     TIM_TimeBaseStructure.TIM_Prescaler = 720;     TIM_TimeBaseStructure.TIM_ClockDivision =0;     TIM_TimeBaseStructure.TIM_RepetitionCounter=0;         TIM_TimeBaseStructure.TIM_CounterMode =       TIM_CounterMode_Up;//TIM_CounterMode_Up;     TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure);     TIM_ClearITPendingBit(TIM2, TIM_IT_Update); // Clear the source     TIM_ITConfig(TIM2, TIM_IT_Update, ENABLE);     TIM_Cmd(TIM2, ENABLE);     }
