Atmel AVR32930: UC3-A3 Xplained Getting Started Guide Features • Easy to reprogram with just a USB cable and a preprogrammed boot loader • Easy to debug code with JTAG-based debuggers and emulators 1 Introduction 32-bit Atmel Microcontrollers Application Note The Atmel® UC3-A3 Xplained evaluation kit is a hardware platform for evaluating the Atmel AT32UC3A3256 microcontroller.
What is needed to get started? To be able to run the preprogrammed code, you need the Atmel UC3-A3 Xplained evaluation kit and a USB cable (Standard-A to Mini-B or Mini-AB) to connect the board to a PC. When connecting the UC3-A3 Xplained board to a PC, the operating system will request a driver file for installing the serial communication driver. This driver file is available in the zip file associated with this document.

AVR32930 3 Board overview Figure 3-1 shows the features on the UC3- A3 Xplained board. For more information on the Atmel UC3-A3 Xplained board, please see the Atmel application note, AVR32918: UC3-A3 Xplained Hardware User’s Guide. Figure 3-1. Overview of the UC3-A3 Xplained board.
4 Connecting the board Connect a USB cable (Standard-A to Mini-B or Mini-AB) between the board and a PC or a USB power supply to power it up. That is all that is needed. When power is applied, the Power/Status LED will light up green. WARNING Do not power the board without having the jumper or an ammeter mounted on the power measurement header. Otherwise, the device may be damaged. The power measurement header is located next to the USB connector, as shown in Figure 3-1. 4.

JTAG connector can be connected to the UC3-A3 Xplained kit with a standoff adapter, as shown in Figure 4-3. Figure 4-3. Connecting the AVR ONE! to the UC3-A3 Xplained board.
5 Programming the kit 5.1 Programming via the boot loader The boot loader is evoked by pushing the physical push button (SW0) during powerup; that is, push the button, and then connect a USB cable to the kit. Programming can be performed by using the BatchISP command line tool, which is part of the FLIP installation. BatchISP can also run under Atmel AVR32 Studio, which has a GUI interface. Once the boot loader is active, it will appear as a USB DFU class device, and Windows will ask for a driver.
AVR32930 The following window will appear on the screen: Figure 5-3. The DFU boot loader file select and programming options. Browse and select the .hex file, set up the options as shown here, and click OK. A small progress bar will appear in the lower right corner to indicate that programming is ongoing. When the progress bar stops and disappears, the programming is done, and the application will start automatically. 5.
