LL ADC with DMA

[IByco]

I have problem with configuration ADC (6 regular channel) and DMA. CubeMX generate next code:

static void MX_ADC_Init(void)
{
... 
/** Configure Regular Channel 
 */
 LL_ADC_REG_SetSequencerChAdd(ADC1, LL_ADC_PATH_INTERNAL_VREFINT);
 /** Configure Internal Channel 
 */
 LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), ADC_CHANNEL_VREFINT);
 /** Configure the global features of the ADC (Clock, Resolution, Data Alignment and number of conversion) 
 */

But Vref not worked (ADC->CCR bit VREFEN is 0 and ADC->CHESEL bit CHESEL17 is 0)

Correct code is:

static void MX_ADC_Init(void)
{
...
/** Configure Regular Channel 
 * LL_ADC_PATH_INTERNAL_VREFINT change to LL_ADC_CHANNEL_VREFINT
 */
 LL_ADC_REG_SetSequencerChAdd(ADC1,LL_ADC_CHANNEL_VREFINT); //Fixed!
 /** Configure Internal Channel 
 * ADC_CHANNEL_VREFINT change to LL_ADC_CHANNEL_VREFINT
 */ 
 LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), LL_ADC_CHANNEL_VREFINT); //Fixed!

For fix it on my application I add next code:

#define ADC_CHANNEL_VREFINT ADC_CCR_VREFEN
...
static void MX_ADC_Init(void)
{
...
/* USER CODE BEGIN ADC_Init 2 */
 LL_ADC_REG_SetSequencerChAdd(ADC1,LL_ADC_CHANNEL_VREFINT); //Fixed!
 /* USER CODE END ADC_Init 2 */

My Cube version 5.1.0 (downloaded at march 21 2019)

Bug still present in most recent version of STM32CubeMX 6.7.0! I had the same issue with the STM32L431RCT6 (https://community.st.com/t5/stm32-mcus-products/stm32l431rct6-internal-temperature-value-too-high-when-using-dma/td-p/93414)! ST should fix this bug!
