 	* configs/stm32f4discovery/src/up_ug2864ambag01.c:  Board-specific
 	  initialization for UG-2864AMBAG01 OLED connecte to STM32F4Disovery.
 	* libxx/libxx_stdthrow.cxx:  Exception stubs from Petteri Aimonen.
+	* configs/stm32f4discovery/src/up_ug2864ambag01.c: Driver has been

+	  configuration could improve the presentation.  Lower resolution displays
