1. Install the FLexible In-system Programming (FLIP) Utility
The FLIP utility can be downloaded using the following link:
http://www.atmel.com/dyn/products/tools_card_v2.asp?tool_id=3886
Alternatively, if you have the A tmel Crypto Evaluation Studio (ACES) software installed, the FLIP installer is available in the
C:\Program Files\Atmel\Crypto Solutions\Firmware\Flip or the C:\Program Files (x86)\Atmel\Crypto Solutions\Firmware\Flip
directory.
2. Place the Atmel AVR® AT90USBxxx into the Device Firmware Upgrade (DFU) Mode
All Atmel AVR AT90USBxxx-based kits are shipped with a default, factory preprogrammed USB boot loader located in the onchip boot section. There are two met hods to enable the DFU mode on the crypto kit s .
1. The first method uses the HWB and RESET buttons on the AT88Microbase board. The AT88Microbase serves as the
base module for the AT30TK175STK, AT88CK101STK3, AT88CK109STK 3, AT88CK101STK8, AT88CK109STK8,
AT88CK201STK, and AT88SC-ADK2 kits.
Enable DFU mode with the HWB and RESET buttons
These steps must be completed in the exact sequence.
1. Press and hold the HWB button
2. Press and release the RESET button
3. Release the HWB button
2. The second method involves using a small DFU- enabling application that is installed with ACES and CMES (Crypto
Memory Evaluation Studio). The application is located at C:\Program Files\Atmel\Crypto Solutions\Firmware\DFU or
C:\Program Files (x86)\Atmel\Crypto Solut ions\Firmware\DFU. Using this app, simply insert the k i t into an available
USB port, wait for enumeration, and then click the Enable DFU button, as shown in Figure 2-2.
Figure 2-2. Device firmware upgrade application
This method is the only way to place t he A T88CK440RED, AT88CK454BLAC K , and AT88CK427GREEN kits into the
DFU mode, as these kits do not have an HWB button.
Note: The kits that incorporate the AT88Microbase board as the base module will toggle all three LEDs prior to
entering the DFU mode. The AT88CK440RED, AT88CK454BLACK, and AT88CK427GREEN kits will
toggle between the red and blue LED three times before entering the D FU mode. Once in the DFU mode,
both LEDs on the AT88CK440RED, AT 88CK454BLACK, and AT88CK427GREEN kits will dimly glow.
