STM32F334 HAL DMA ADC Scan conversion not working

Hello. 

 

In my project, I use the ADC configured in scan mode, as seen on this screenshot from STM32CubeMX:

and the DMA configured as follows:

 

The problem is that I can't get any data transferred from ADC to memory, when I call

volatile uint32_t ADC1ConvertedValues[2];

HAL_ADC_Start_DMA(&hadc1, (uint32_t*)ADC1ConvertedValues, 2);

When I open the peripheral view on Keil uVision I can see that the ADC is working properly and the conversions are happening.

 

Can you tell me where's the problem?
