14.3 Using the RFU Utility

Support for downloading new application firmware to the gateway is provided by

the free Rabbit Field Utility (RFU), which is a 32-bit application that runs on

Microsoft Windows platforms. The RFU utility can be downloaded from ICC's

home page at http://www.iccdesigns.com. When downloading a new gateway

application BSP, always confirm that you also have the latest version of RFU,

as new .BIN firmware files contained in BSPs may require functionality found

only in the most recent RFU versions for successful downloading.

The remainder of this section will detail the RFU utility configuration and

firmware download procedures.

When first downloaded, the RFU utility files are compressed into one self-

extracting .EXE distribution file. Create a folder (such as c:\RFU), place the

distribution file in this folder, and then execute it. This will extract the

compressed files into that same folder. The distribution file is then unneeded

and can be deleted if desired. To run the RFU utility, double-click on the

RFU.EXE file icon.

The first time the RFU utility is run on a computer, several configuration items

need to be confirmed. These configuration items are retained in the computer's

registry from that point on, so reconfiguration is not required unless certain

parameters (such as which serial port to use on the computer) are changed.

The two configuration items that need to be confirmed are the communications

and bootstrap loaders path. First, select the "Setup...Communications" menu

item (refer to Figure 32).

The Communications Options window shown in Figure 33 then appears.

Confirm that the settings are as shown, with the possible exception of the
