ADC Scan Conversion Mode + DMA with Cache Issue

[THIHA KYAW]

Hi,

I used  ADC Scan Conversion Mode + DMA  to read the values from 7 channels of ADC1.

But the adc reading values are not correct when I enable the cache.

/* Enable I-Cache-------------------------------------------------------------*/

// SCB_EnableICache();

 /* Enable D-Cache-------------------------------------------------------------*/

// SCB_EnableDCache();

What could be the problem?

ADC setting is as below.

Regards,
