Well your original post says "Le croquis utilise 179618 octets (70%) de l'espace de stockage de programmes. Le maximum est de 253952 octets"
This is about right for a mega2560 based board, but not for a ATSAM3X8E that is same processor as arduino DUE.
If I compile for a RADDS controller ( a popular DUE based controller) I get "from 524288 bytes" a much larger and expected number
Looking around no one has made marlin work on this board. All they have done is replace the controller with a RAMP's
So my guess is you setup Marlin for a RAMPS and the arduino IDE for a mega2560 and attempted to upload it to a DUE based board.
This will not work.
