Problem with I2c1 on PB8, PB9 STM32F103VET6 using cube

Question asked by nguyen.phong.001 on Sep 18, 2016
Hi All,
I config I2C1 on PB8 and PB9 using CubeX. After run this function the sdw con not run and disconnect with chip. When I debug i saw  hte program run before  __HAL_AFIO_REMAP_I2C1_ENABLE(); after this my debug port disconnect.
Anyone help me?. Thanks
void HAL_I2C_MspInit(I2C_HandleTypeDef* hi2c)

  GPIO_InitTypeDef GPIO_InitStruct;
  /* USER CODE BEGIN I2C1_MspInit 0 */

  /* USER CODE END I2C1_MspInit 0 */
  B9     ------> I2C1_SDA 
    GPIO_InitStruct.Pin = GPIO_PIN_8|GPIO_PIN_9;
    GPIO_InitStruct.Mode = GPIO_MODE_AF_OD;
    /**I2C1 GPIO Configuration    
    PB8     ------> I2C1_SCL
    PO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
    HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);


    /* Peripheral clock enable */
  /* USER CODE BEGIN I2C1_MspInit 1 */

  /* USER CODE END I2C1_MspInit 1 */
