MSPM33-SDK: ADC management, different reactions

Part Number: MSPM33-SDK
Other Parts Discussed in Thread: MSPM33C321A

Hello,

I developed a SW project (on MSPM33C321A), where inside I use 2 ADC. 

When I download this project on the eval board (in debug mode), I see the ADC live correctly and return good value.

But when I download exactly the same project, on own electronic board, the values returned, are always at 4095 (0xFFF -> 12 bits).

I do not understand where comes from the difference between both electronic boards ?

Is it an HW difference ?

Thanks
