STM32G431C + ADC + DMA

[AChas.1]

I'm using ADC with DMA in a large project, and faced some very strange problem: 

If I'm using DMA2 Channel 6 - ADC works correctly 

If I'm using DMA2 Channel 1 - the SW end up in Hard Fault 

The configuration is default. 

This is how I start the conversation 

  HAL_ADCEx_Calibration_Start(&hadc1, ADC_SINGLE_ENDED);
  // Start the ADC in DMA mode
  HAL_ADC_Start_DMA(&hadc1, (uint32_t*) g_ADC_values, ADC_BUFFER_LENGTH);
