MCIMX6Y2CVM08AA processor - VDDA_ADC_3P3 pin voltage is 3.9V without the power input to this particular voltage input pin L13 (VDDA_ADC_3P3)

[jayebc]

Hi,

On the custom hardware we are using MCIMX6Y2CVM08AA processor. After power ON, all the voltage levels are fine except the VDDA_ADC_3P3 which is 3.9V so i remove the power input to this particular voltage input pin L13 (VDDA_ADC_3P3) but still see a voltage level of 3.9V on this pin (without power connected to this particular pin).

Can you please suggest us any debugging steps or a solution if this is a known issue.

Thanks.
