想通过基本定时器6定时进入中断，但用jlink调试时，怎么也进不了中断函数，下面是我写的程序
#include "main.h"
#include "stm32f1xx_hal.h"
#include "tim.h"
#include "gpio.h"
void SystemClock_Config(void);

void TIM6_IRQHandler()
{
TIM6->SR&=0xfffe;
printf("hello\n");
}

int main(void)
{
  SystemClock_Config();
RCC->APB1ENR|=1<<4;
TIM6->ARR=5000;
TIM6->PSC=71;
TIM6->CR1|=1<<7;
MY_NVIC_Init(2,1,TIM6_IRQn,2);

TIM6->DIER=1<<0;
TIM6->CR1|=0x01;
while (1)；
}
void SystemClock_Config(void)
{

  RCC_OscInitTypeDef RCC_OscInitStruct;
  RCC_ClkInitTypeDef RCC_ClkInitStruct;

/**Initializes the CPU, AHB and APB busses clocks
*/
  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE;
  RCC_OscInitStruct.HSEState = RCC_HSE_ON;
  RCC_OscInitStruct.HSEPredivValue = RCC_HSE_PREDIV_DIV1;
  RCC_OscInitStruct.HSIState = RCC_HSI_ON;
  RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
  RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;
  RCC_OscInitStruct.PLL.PLLMUL = RCC_PLL_MUL9;
  if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
  {
_Error_Handler(__FILE__, __LINE__);
  }

/**Initializes the CPU, AHB and APB busses clocks
*/
  RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK
                           |RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;
  RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;
  RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
  RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV2;
  RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;

  if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_2) != HAL_OK)
  {
_Error_Handler(__FILE__, __LINE__);
  }

/**Enables the Clock Security System
*/
  HAL_RCC_EnableCSS();

/**Configure the Systick interrupt time
*/
  HAL_SYSTICK_Config(HAL_RCC_GetHCLKFreq()/1000);

/**Configure the Systick
*/
  HAL_SYSTICK_CLKSourceConfig(SYSTICK_CLKSOURCE_HCLK);

  /* SysTick_IRQn interrupt configuration */
  HAL_NVIC_SetPriority(SysTick_IRQn, 0, 0);
}
