2.5.1 Flashing Firmware
The SmartSonic board should already be pre-flashed with the correct firmware to run the cliff detection demo. In the event you need
to reflash the firmware or flash a different firmware, the steps to do this are:
1. Power off the board by unplugging the micro-USB cable.
2. Move the power selection jumper to bridge the EDBG pins (middle position, as shown in Figure 7).
3. Plug the micro-USB cable into the EDBG-USB connector.
4. I n the demo GUI, in the upper left corner on the GUI, click on the down arrow next to “Connect” to show the firmware flash
dropdown menu.
5. Click “Flash Default Firmware” to flash the default firmware, or click “Flash Firmware” to select a specific firmware file to flash.
6. Wait for the firmware flash to complete. The amber LED on the SmartSonic will blink repeatedly during this process. The GUI
will show a prompt once flashing is complete.
7. Unplug the micro-USB cable from the board.
8. Move the power jumper back to the first position to bridge the FTDI pins (as shown in Figure
