When the ISEB is connected, the correct firmware is selected,
and the downloader is fully configured, follow these steps to
flash the firmware:
1.

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.
Installing the ADXRS800 Software Evaluation GUI
The software GUI installation has been created to include any
required National Instruments drivers and run-time engines
that are necessary for proper operation. To run the software
GUI installation routine, double-click the setup.exe file located
in the /ADXRS800 Evaluation Software/ folder on the
included CD. The window shown in Figure 11 is displayed.

The download begins and is automatically verified by the
downloader.
If the downloading process fails, which is indicated in the
Monitor Status box (see Figure 8), attempt the download
again by clicking Start and then pressing the appropriate
switch combination. It may take a few attempts to reprog-
ram the board successfully.
After the download has completed successfully, click Run
(as shown in Figure 8) to reset the ISEB and to begin
running the new firmware.
When this step is complete, the board is updated correctly.
