UPDATING/REPAIRING THE ISEB FIRMWARE
In the event that the ISEB firmware becomes corrupted or must
be updated, the CD contains the necessary programming utility to
flash the ISEB microcontroller. Also available on the CD is the
version of firmware available at the time of release of the EVAL-
ADXL346Z-M system (Version 1.3). In addition, as new firmware
is made available, it can be downloaded from the Analog Devices
website (www.analog.com).
To flash the ISEB microcontroller, follow these steps.

The downloader file should come configured for the
microcontroller on the ISEB. The only option that may need to
be changed is to select the correct COM port from the Serial
Port menu on the Comms tab (see Figure 8). When the COM
port is selected, click OK to accept the changes and go back to
the main screen.
Ensure that the ISEB is connected to and detected by the
PC. The COM port that the device is recognized on must
also be obtained, as mentioned in the previous sections.
Run the ARMWSD.exe program located in the
/Drivers/FW/ folder, which displays information about the
downloader, as shown in Figure 7.
Click Browse… and select the ADI_ISEB_FW_1_3.hex
file located in the /Drivers/FW/ folder or the most recent
firmware obtained from the Analog Devices website
(www.analog.com).
Click Configure to display the screen shown in Figure 8.

When the ISEB is connected, the correct firmware is selected,
and the downloader is fully configured, follow these steps to
flash the firmware.

The download then begins and is automatically verified by the
downloader. If the downloading process fails, which will be
indicated in the Monitor Status box (see Figure 7), attempt the
download again by clicking Start and then the appropriate
switch combination. It may take a few attempts to reprogram
the board successfully.
After the download is completed successfully, click Run, as shown
in Figure 7, to reset the ISEB and to begin running the new firm-
ware. When this step is complete, the board is updated correctly.
Updating the firmware may require that a new evaluation GUI
be obtained. If the firmware on the CD is used to flash the ISEB,
the evaluation GUI on the corresponding CD is sufficient. If the
firmware used is obtained from the Analog Devices website
(www.analog.com), the most recent version of the evaluation
GUI, which is also located on the website, should be used.
Click Start, as shown in Figure 7, to initiate the flashing
process. After clicking Start, the two buttons on the ISEB
shown in Figure 9 must be pressed, in a specific order, to
flash the firmware.
Press and hold down SW1.
With SW1 held down, press and release SW2.
Release SW1.
