ADC Problem with the STM32-H107 board

[tach]

Hello,

I have a problem with the ADCs when using the STM32-H107 board. I have not a linear conversion.
But with the same program and an STM32-P107 board, the ADCs work well!
Can someone help me to resolve the problem?

There is the result for the two boards:
