why my firmware becomes unstable with b-g431-ESC1 MCU revision X

Hi,

as explained into the title, i am developing a firmware on this board which is stable. i have bought a new set of board and after flashed, the firmware becames unstable :unamused_face:

Searching a reason why i have seen that the MCU revision is not the same: Y with my first board set on which the firmware is stable, X with the second set giving unstability. Please what is the problem ? what i need to adapt ?

Hi Cedric,

Indeed i observe that the plots are very similar. I do not use SDK, i use cube mx to generate configuration i need and the other part is my own code using some function from HAL library.

Hello @coren.1 ,

So the last thing I can suggest you is to use the SDK with your two boards version X and Y and check that you have the same behavior.

Best Regards
