I am trying to use ADC with 2 channels and DMA, but I only get 1 reading before the overrun bit gets set. Also the 1 reading is wrong, I am expecting a value of approx 2100, but I am getting around 70. I can see in the hadc->DR that the value are cor...

changing hadc.Init.ContinuousConvMode = ENABLE; to DISABLE fixed the overrun problem. But I am still not getting the correct value from ADC DR. I looked in the DMA registers and nothing in the channel configuration register(CRR1) is set, except EN (e...

Noticed that the prescaler was set to 10. Which divides the USART source clock by 10. It was probably too slow to handle the task. Set it to 1 and it works fine

For me, this was solved by setting all pins in HAL_SD_MspInit function to GPIO_PULLUP
