1. Make sure that a jumper is present at the pins indicated by the red arrow in
2. Assemble the top card with the STK600 board
3. To communicate over RS232 port connect PD2 and PD3 pins to RXD and TXD
pins of RS232 SPARE port of the board respectively. This is required by Sample
Applications provided within the BitCloud SDK and Serial Bootloader. Custom
applications are free to choose other pins.
Before performing any further operations, perform the steps required to get started
. Refer to AVR Studio help for details on that subject. At least
make sure that the STK600 firmware is up to date, and configure the voltage provided
by the STK600 for the ATmega128RFA1 top card. For that, perform the following
steps:
a. Attach the STK600 to a PC using a USB cable
b. In AVR Studio, open the
Tools > Program AVR > Connect…
dialogue
c. Choose STK600 as the platform, and press
Connect
d. Update the STK600 firmware, if prompted
e. Go to the
HW Settings
tab
f. Specify the 3.3V in the VTarget field and press
Write
The user needs to perform this procedure only once for each STK600 board.
10.1.2.1 OTAU hardware setup
To demonstrate OTA upgrade functionality, the pins of the serial DataFlash device
(AT45DB041) hosted on the STK600 board (marked DATAFLASH on the board) must
be connected to the ATmega128RFA1 pins, as shown in
Table 10-1. External flash and MCU pin assignment.
