configure the voltage provided by the STK600 for the ATxmega socket card. For
that, perform the following steps:
a. Attach the STK600 to a PC using a USB cable.
b. In Atmel AVR Studio, open
Tools > Program AVR > Connect…
dialogue.
c. Choose the correct Platform = STK600, and press
Connect
.
d. Update the STK600 firmware, if suggested.
e. Go to the
HW Settings
tab.
f. Specify the required voltage in the VTarget field, and press
Write
.
Please note that the voltage should be less than 3.6V (for example,
3.0V).
You need to perform this procedure once for each ATSTK600 board.
11.1.2.1 OTAU hardware setup
If you wish to demonstrate OTA upgrade functionality, a serial Atmel DataFlash
device (AT45DB041) shall be connected to the Atmel ATxmega256A3/Atmel
ATxmega256D3 pins specified in
The Atmel STK600 board already has built-in DataFlash, and so to use OTAU on an
STK600, it is sufficient to connect the
SI
,
SO
,
SCK
, and
/CS
pins under the DataFlash
pin heading to the corresponding MCU pins noted in
Table 11-1.
