3.1 Preprogrammed firmware

The Atmel AT32UC3L064 and the Atmel AT32UC3B1256 that come with the Atmel

UC3-L0 Xplained kit are both preprogrammed.

The preprogrammed firmware in the AT32UC3L064 is set up with a small demo with

the Atmel QMatrix touch slider and Atmel QTouch button that can be used to control

the RGB LED. The device also features a UART boot loader that can be used to

program new firmware to the device. Hold the mechanical button while applying

power to start the boot loader. The boot loader can be used with the command line

tool “batchISP” delivered with FLIP.

The preprogrammed AT32UC3B1256 firmware offers features such as a boot loader

for self-programming of the board controller itself and a UART-to-USB gateway. The

bootloader can be started by shorting the 2-pin header (not mounted) while applying

power to the board. The bootloader can be used with the command line tool

“batchISP” delivered with FLIP.
