If it is desired to program the kit without the help of the
on-chip bootloader, or if debugging is required, it is possible to do this with various
tools. The most common tools and how they can be connected are listed in the section
Connecting the kit.Atmel Studio can be used as front-end for these
programming tools.
Note:
Because JTAG TDO and PDI DATA are connected on the
PCB for this kit, JTAG must be disabled on the device in order to use PDI. JTAG can
be disabled by programming the JTAGEN fuse of the device.
