Hi, I remove thermal sensor protection :

//#define THERMAL_PROTECTION_HOTENDS // Enable thermal protection for all extruders //#define THERMAL_PROTECTION_BED // Enable thermal protection for the heated bed //#define THERMAL_PROTECTION_CHAMBER // Enable thermal protection for the heated chamber

Now can boot properly, but , displaying -14° on both when sensor are connected ! What is wrong whith this board ?

Hi, Do not use this firmware, use original "MARLIN BUGFIX 2.0" , and chose "BIGTREETECH MINI V1.1" Do not update libraries , and work fine. Regards
