16. Firmware Updates

The interface’s embedded firmware resides in flash memory that can be

updated in the field. Firmware updates may be released for a variety of

reasons, such as custom firmware implementations, firmware improvements

and added functionality as a result of user requests.

Toshiba is continually striving to enhance the functionality and flexibility of our

products, and we therefore periodically release new embedded firmware to

achieve these goals and meet customer requests. Flash firmware files and all

related documentation (such as updated user manuals) can be downloaded as

complete board support packages (referred to as BSPs) from

http://www.iccdesigns.com

. It is suggested that users check this Internet site

prior to installation, and then periodically afterwards to determine if new support

packages have been released and are available to upgrade their units.

16.1 Requirements

Besides the new firmware file, firmware updates require a PC with a Windows

operating system (Windows 95 or newer) and a serial port, the RFU PC

application (refer to section 16.3), and the RS232 cable included with the

interface kit (ICC part number 10425) to connect the RS232 port of the unit to

the PC.

Please be sure to read the firmware release notes and updated user’s manual

(included with the BSP) for any important notices, behavior precautions or

configuration requirements prior to updating your firmware. For example,

upgrading to a new firmware version may affect user-defined configuration files:

prior to starting an update procedure always back up your configuration file to a

PC for later recovery if necessary.

16.2 Connection

IMPORTANT: Note that the interface will not be operating its system

control and communication tasks while its internal firmware is being updated.

Therefore, be sure to shut down the system to a known safe state prior to

initiating the firmware update procedure.

Connect the #10425 serial port cable between the RS232 port of the interface

and the computer’s serial port. Move DIP switch #1 to the “ON” (up) position:

this will place the interface into the “firmware download” mode. Whenever DIP

switch #1 is “ON”, the interface can only download firmware to its flash memory:

all other application functions (such as communications, console access etc.)

will be disabled.
