HAL_TIM_Base_Start_DMA - STM32CubeMX

I've try to use HAL_TIM_Base_Start_DMA with TIM6.

To configure the system I'm using STM32CubeMX. We I start the project I can't receive any interrupt...

HELP.

In Attachment the ioc file.

My change after code generation:

In red tim.c file modify:

#include ''tim.h''

#include ''dma.h''

/* USER CODE BEGIN 0 */

uint32_t aCCValue_Buffer[3] = {10000, 1000, 100};

/* USER CODE END 0 */

...

    /* Peripheral interrupt init */

    HAL_NVIC_SetPriority(TIM6_IRQn, 0, 0);

    HAL_NVIC_EnableIRQ(TIM6_IRQn);

  /* USER CODE BEGIN TIM6_MspInit 1 */

HAL_TIM_Base_Start_DMA(tim_baseHandle, aCCValue_Buffer, 3);

  /* USER CODE END TIM6_MspInit 1 */

....

/* USER CODE BEGIN 1 */

void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) {

HAL_GPIO_TogglePin(LD2_GPIO_Port, LD2_Pin);

}

/* USER CODE END 1 */

Too few information here. How do you configure the timer? Do you enable the DMA? Do you implement the DMA interrupt? What about the DMA configuration?

Post the whole project.

Solution in attachment.

Look the Led on NUCLEO F070RB!!

the problem was in the configuration of DMA trasfer using halfword instead of word.
