NOTE
The Atmel UC3-L0 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
AT32UC3L064.
For the location of the respective headers, refer to
The Atmel AT32UC3L064 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 AVR 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 Pin 1 on the JTAG header is at the top right
corner. This is rotated 180° compared to the other headers (J1, J2, J3, and J4).J1, J2,
J3, and J4).
Table 4-1. UC3 programming and debugging interface – JTAG.
The Atmel AT32UC3B1256 can be programmed through its boot loader. The boot
loader is evoked by shorting the two holes close to the device before applying power
to the board. The two holes have 100mil spacing, so the user can solder in a two-pin
header and use a jumper to easily enter the boot loader. Programming is performed
through the boot loader programmer target in the Atmel AVR32 Studio.
Alternatively, the AT32UC3B1256 can also be programmed by connecting a
programming tool, such as JTAGICE mkII, to the 10-pin test points on the bottom side
of the board (marked with BC JTAG).
It is not recommended to program the AT32UC3B1256 using a programming tool, as
this will erase the boot loader.
