subject. At least make sure that the STK600 firmware is up to date, and 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 AVR Studio, open the

c. Choose STK600 as the platform, and press
Connect
d. Update the STK600 firmware, if prompted
e. Go to the

Please note that the voltage should be less than 3.6V (for example,
3.0V)
The user needs to repeat this procedure only once for each STK600 board.
