This method of programming allows the application and the boot loader to coexist. 

The preprogrammed DFU boot loader is located in the “Boot Loader Flash Section” of 
the on-chip flash memory; it manages the USB communication protocol and mainly 
performs read/write operations to the on-chip memories (flash/EEPROM). 

Two ways are available to evoke the boot loader on the Atmel AVR XMEGA-B1 
Xplained board: 

•  Automatic if the “Application Flash Section” of the Atmel ATxmega128B1 is blank 

when power is applied 

•  Forced if pin 6 on J1 is shorted to GND when power is applied
