It is like DMA never starts.Any ideas?below is the code./* USER CODE END TIM6_Init 0 */ TIM_MasterConfigTypeDef sMasterConfig = {0}; /* USER CODE BEGIN TIM6_Init 1 */ /* USER CODE END TIM6_Init 1 */ htim6.Instance = TIM6; htim6.Init.Prescaler = 42-1;...

Working!!!!!!! =) I have had to initialise DMA manually before calling to HAL_DAC_Start_DMA. Something is not correct in the cubemx generating the correct code. :\

No, it doesn't crash and not hardfault.No error, but status is 02 (HAL_DMA_STATE_TIMEOUT)Memory is a variable in RAM const uint8_t myDAC_Signal[7]={0, 40, 80, 120, 160, 200, 240}; Initialisation: (see the code) /* Initialize all configured periphera...

I am using a chinese STM32F407 board. I am trying to use DMA to generate a wave signal through the DAC1 channel. Without DMA DAC y works, but I have not be able to generate the signal using DMA.
