STM32F303K8 ADC-DMA issue, DMA not firing I have strange DMA problem with a F303 application, in particular a STM32F303K8 (a STM32F303x6/8 variant).The concept is relatively straightforward.A configured ADC sequence is triggered by timer, the ADC in turn triggers DMA transfers of the conversion results, and the DMA raises the TC interrupt when the specified number of transfers is reached.The problem is, the ADC almost immediately raises the OVR flag (overflow), and the DMA is disabled (CCR.EN is reset).I can't see the reason why.Detailed description of used peripherals / resources : - ADC1_IN1, ADC1_IN2 & ADC1_IN4, 19.5 cycles, with ADC.CCR CKMODE=3 (synchronous, HCLK/4) - TIM3 TRGO as ADC trigger (ADC1.CFGR EXTSEL=4, EXTEN = 1), at about 11kHz - assigned DMA is DMA1 Channel 1 (see RM0316 Rev 10, table 77 at page 268)DMA is configured in circular mode, peripheral-to-memory transfer, memory increment, and half-word transfers.At the moment I try only one sequence (3 samples, i.e. half-words), instead of a l
