1. Make sure a jumper is present at the pins indicated by the red arrow in
2. Assemble the Atmel ATAVR128RFA1-EK1 on top of an Atmel STK600 board.
3. To communicate over the RS-232 port, connect pins PD2 and PD3 to pins RXD
and TXD, respectively, of the RS-232 SPARE port on the board. This is required
by the sample applications provided with the Atmel BitCloud SDK and Serial
Bootloader. Custom applications are free to choose other pins.
Before continuing any further operations, perform the steps required to get started
with the Atmel ATSTK600
. Refer to AVR Studio Help
subject. At the very least, make sure that the Atmel STK600 firmware is up to date,
and configure the voltage provided by the STK600 for the Atmel ATmega128RFA1
top card. For that, perform the following steps:
1. Attach the STK600 to a PC using a USB cable.
2. In Atmel AVR Studio, open the
Tools > Program AVR > Connect…
dialogue.
3. Choose the correct Platform = STK600, and press Connect.
4. Update the STK600 firmware, if suggested.
5. Go to the HW Settings tab.
6. Specify 3.3V in the VTarget field, and press Write.
The actions above must be performed only once for each ATSTK600 board.
9.1.2.1 OTAU hardware setup
If you wish to demonstrate OTA upgrade functionality, a serial Atmel DataFlash
device (AT45DB041) should be connected to the ATmega128RFA1 pins, as specified
The 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 9-1.
