I can not start ADC with cyclic data transfer via DMA to stm32h743.

Hi.

Here is my code:

	MODIFY_REG(RCC->D3CCIPR, RCC_D3CCIPR_ADCSEL, 0 << RCC_D3CCIPR_ADCSEL_Pos);
	RCC->AHB1ENR |= RCC_AHB1ENR_ADC12EN; 
	DMAMUX1_Channel0->CCR = (9 << DMAMUX_CxCR_DMAREQ_ID_Pos); // подключение через MUXDMA DMA1_�?трим_0 к ADC1
 
	DMA1_Stream0->CR &= ~DMA_SxCR_EN; 
	while(DMA1_Stream0->CR & DMA_SxCR_EN); 
	DMA1_Stream0->CR = DMA_SxCR_MSIZE_0 | DMA_SxCR_PSIZE_0 | DMA_SxCR_MINC | DMA_SxCR_CIRC | DMA_SxCR_DIR_0;
	DMA1_Stream0->NDTR = 5;
	DMA1_Stream0->PAR = (uint32_t)&ADC1->DR; 
	DMA1_Stream0->M0AR = (uint32_t)&bufAdcData; 
 
 
	ADC12_COMMON->CCR = ADC_CCR_VBATEN

	ADC1->CR |= ADC_CR_ADEN; 
	while(ADC1->IER & ADC_ISR_ADRDY); 
	ADC1->CR |= ADC_CR_ADCAL;
	while(!(ADC1->CR & ADC_CR_ADCAL)); 
    ADC1->CFGR = ADC_CFGR_JQDIS | (ADC_CFGR_DISCNUM_2 | ADC_CFGR_DISCNUM_0) | ADC_CFGR_DISCEN | ADC_CFGR_CONT | ADC_CFGR_DMNGT_1 | ADC_CFGR_DMNGT_0;

	ADC1->HTR1 = 0x00;
	ADC1->HTR2 = 0x00;
	ADC1->HTR3 = 0x00;
 
	ADC1->SQR1 = (ADC_SQR1_SQ1_1 | ADC_SQR1_SQ1_0)
			| (ADC_SQR1_SQ2_3 |  ADC_SQR1_SQ2_0)
			| (ADC_SQR1_SQ3_3 | ADC_SQR1_SQ3_2 | ADC_SQR1_SQ3_1 | ADC_SQR1_SQ3_0)
			| (ADC_SQR1_SQ4_4 | ADC_SQR1_SQ4_1); 
 
	ADC1->SQR2 = (ADC_SQR2_SQ5_4 | ADC_SQR2_SQ5_1 | ADC_SQR2_SQ5_0); 
	ADC1->SQR3 = 0;
	ADC1->SQR4 = 0;
	DMA1_Stream0->CR |= DMA_SxCR_EN;

	MODIFY_REG(GPIOA->MODER, GPIO_MODER_MODE3, 0x3 << GPIO_MODER_MODE3_Pos);

	MODIFY_REG(GPIOB->MODER, GPIO_MODER_MODE0, 0x3 << GPIO_MODER_MODE0_Pos);
 
	MODIFY_REG(GPIOA->OSPEEDR, GPIO_OSPEEDR_OSPEED3,0x0 << GPIO_OSPEEDR_OSPEED3_Pos); 
	MODIFY_REG(GPIOA->OSPEEDR, GPIO_OSPEEDR_OSPEED4,0x0 << GPIO_OSPEEDR_OSPEED4_Pos);

	MODIFY_REG(GPIOB->PUPDR, GPIO_PUPDR_PUPD0, 0x00 << GPIO_PUPDR_PUPD0_Pos);
 
	MODIFY_REG(GPIOA->AFR[0], GPIO_AFRL_AFSEL3, 0x0 << GPIO_AFRL_AFSEL3_Pos); 
	MODIFY_REG(GPIOA->AFR[0], GPIO_AFRL_AFSEL4, 0x0 << GPIO_AFRL_AFSEL4_Pos); 
	MODIFY_REG(GPIOA->AFR[0], GPIO_AFRL_AFSEL5, 0x0 << GPIO_AFRL_AFSEL5_Pos);
	MODIFY_REG(GPIOA->AFR[0], GPIO_AFRL_AFSEL6, 0x0 << GPIO_AFRL_AFSEL6_Pos);
	MODIFY_REG(GPIOB->AFR[0], GPIO_AFRL_AFSEL0, 0x0 << GPIO_AFRL_AFSEL0_Pos); 
 
	ADC1->CR |= ADC_CR_ADSTART;
 

All data in the buffer are zeros.

What am I doing wrong?
