DMA + ADC doesn't work

CubeIDE 1.1.0

STM32Cube_FW_WB_V1.3.0

Trying to make DMA transfer ADC results.

I'm putting code in main() after MX_..._Init() and before while(1) {}

HAL_ADC_Start_IT(&hadc1); works fine

HAL_DMA_Start_IT(&hdma_memtomem_dma1_channel2, (uint32_t) src, (uint32_t) dest, 40); works fine too

but

HAL_ADC_Start_DMA(&hadc1, dest, 10) doesn't work as it should

ADC is activated and keeps throwing Overrun_Error

But DMA doesn't transfer anything

I've tried this confuguration on PNUCLEO-WB55 Dongle in far more complex code and it worked. Now I'm using custom board and just main() body. But I think the board should not matter as DMA is totally internal thing
