In the code:
adcbuf[1]=1;
noise_buf[1]=4;
uint32_t hal_status = HAL_OK;
static uint32_t buftransit = 125;
buftransit=2;
noise_buf[2]=buftransit;
HAL_LPTIM_PWM_Start(&hlptim3, 0XFFFF, 0X7FFF);
HAL_DMAEx_EnableMuxRequestGenerator(&hdma_dma_generator0);
HAL_DMA_Start(&hdma_dma_generator0, (uint32_t)&adcbuf[1], (uint32_t)&buftransit, 1);
hal_status = HAL_MDMA_Start(&hmdma_mdma_channel41_dma1_stream0_tc_0, &adcbuf[1],
&noise_buf[0],
2,
3);
By removing the word 'static' from line 4 causes to MDMA stop woring after 3 buffer transfer. Full code is appended on STM32cubeIDE 1.10.1 STM32F743vit6
