connection between the common power plane VCC_P3V3 and the VCC_MCU_P3V3
power plane. By replacing the jumper with an amperemeter it is possible to determine
the current consumption of the Atmel AT32UC3A3256. To locate the power
measurement header, please refer to
Do not power the board without having the jumper or an amperemeter
mounted. Otherwise, the device may be damaged.
The kit can be programmed either from an external programming tool or through a
USB bootloader which is pre-programmed on the device.
The bootloader is evoked by pushing the push button (SW0) during power-on. I.e.
push button and then connect an USB cable to the kit. Programming can be
performed through the DFU target (bootloader programmer target) in the Atmel
AVR32 Studio.
How a programmer can be connected to the kit is described in Chapter 4.1.
The Atmel UC3-A3 XPLAINED kit has five 10-pin, 100mil headers. Two headers have
a fixed communication interface (J1 and J4). One header has analog functionality
(J2), and the last header (J3) has general purpose digital I/O.
The 90° angled header is the JTAG programming and debugging header for the
AT32UC3A3256.
For the location of the respective headers, refer to
The AT32UC3A3256 can be programmed and debugged by connecting an external
programming/debugging tool to the JTAG header. The header has a standard JTAG
programmer pinout (refer to online help in AVR32 Studio), and tools such as
JTAGICE mkII or AVR ONE! can thus be connected directly to the header.
The grey female 10-pin header on JTAGICE mkII has to be used when connecting to
the kit. A scoring in the board is made to fit the orientation tab on the header.
A standoff adapter (no. 1) is needed when using AVR ONE!.
Pin 1 on the JTAG header is at the top right corner and is marked with a square pad.
