XMEGA128A3U device now makes easy to implement and use USB. The XMEGA128A3U with USB interface can be factory configured or reprogrammed
with a USB boot loader located in the on-chip flash boot section of the controller.This USB boot loader allows performing in-system programming (ISP) from a USB
host controller without removing the part from the system, and without any external programming interface other than the USB connector.
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
- Newest XMEGA microcontroller comes with USB .
- Great board with prototyping area for building your Xmega project.
- An external programmer is no need,the Xmega bootloader makes programming very very easy.
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Atmel provides bootloader and a USB host loader application called FLIP which works with several Windows? OS.
Bootloader for Xmega128A3U Microcontroller:

The XMEGA128A3U microcontroller has been factory configured or reprogrammed with above bootloader located in the on-chip flash boot section of the controller.So you can use the
self-programming apllication directly and no need an external programmer.
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Once the boot loader is properly recognized and installed on the operating system,the part can be programmed using FLIP. This section gives a short step-by-step
introduction about how to use FLIP to program a part. For detailed documentation,please refer to the online help for FLIP.
.Start FLIP
.Select the part from the device selection list available with the ‘Device’ icon.
.Select “USB” as communication media available with the “USB cable icon” .
.Keep the "KEY6/BOOT"button pressed and Open the USB port to connect to the target
. Select the .hex file you want to download using “File”-> “Load HEX File” menu.
.Select the ‘Erase’, ‘Blank check’, ‘Program’ and ‘Verify’ operation check boxes (1)and press the ‘Run’ button (2)
You should get confirmation in the bottom section of the window (3) that the FLASH was successfully programmed and verified.
.Press ‘Start Application’ button (4) to execute the loaded application
