The DMA buffer configured with a multichannel ADC setup ( Processor STM32f769II) shows values in different buffer location with respect to the rank configured in the ADC setup. How can this be fixed?

We have connected 7 channels in ADC2 to a STM32F769II processor. The DMA to ADC is enabled and the rank for conversion too is configured. But on testing, the ADC values are being shown in buffer location very different from its rank.This happened in ...
