Problem with ADC in STM32L476RGTx

Currently I am working in an application using STM32 controller.I am facing one issue.I am using 2 ADC's which are working for the first time right after flashing.

We use the independent MCU PCB(STM32-L476RGTx)unit to flash and test our application.When we flash,for the first time both ADC's are working.But when we switch off and switch on the board,one of the ADC is not reading values.

The same scenario is working without any fail in the nucleo development board.So what would be the difference between the nucleo development board and the custom PCB with MCU.

Please help me to overcome this issue.

one of the ADC is not reading values

What exactly does this mean? Do you use different ADC units, or just different inputs within one ADC unit? 'ADC is not reading values' means that the values are unexpected, or that the ADC does not finish the conversion? Do you use some sort of 'library'? Reduce your code to functional minimum which exhibits the problem and post it here.
