3.3.5 Software download

1) Overview This document describes the specification of the Flash-downloading tool (Upgrading Tool) used for the user service.

2) Purpose of this document The aim of this document is to provide a sufficient description of the GX20 Upgrading Tool for readers.

3) Scope This document covers the description of the Flash-downloading tool specification for the user service.

4) Operating environment

Operating environment for the Upgrading Tool

OS: Windows 98, 98SE, 2000 or XP Downloadable file: Only Motorola format is available for downloading. Communication mode: Asynchronous mode Data length: 8 bit Parity bit: None Stop bit length: 1 bit

Operating environment for the loading loader

Phone: GX20 Communication mode: Asynchronous mode Data length: 8 bit Parity bit: None Stop bit length: 1 bit

1) Activation You can start the application either from the short cut on your desktop or Start menu.

2) The Upgrading Tool (on the PC)

Note 1) If using “Communication Box Ver. 2G”, the only the phone connected to No.1 cable is controlled on your PC.

Note2) The time displayed in this dialog indicates a margin of processing time taken for data to be downloaded to the phones that are connected to cable No.2 to No.10 of the “Communication Box Ver. 2G”. If an error occurs, increase this margin time. See the section 3.3.5.2 (3) “Using the Communication Box Ver. 2G” on page 2-20 for details.

[Caution!]

• If you wish to download using “Communication Box Ver. 2G”, power on from No.10 to No.1 after “Sending Sync Byte…/Press Power Button” message has appeared.

• Use a fully charged battery and remove the check from “Communication Box” if using a Data cable for the downloading operation.

• Start downloading after the phone has been properly turned off in order to clear the Backup RAM.

• If you select “FileSystem Initialize” for the download, user’s data stored in the phone will be deleted. Care should be taken for this performance.

3) The loading loader (on the phone side) The progress indication of the operation and error status are displayed on the phone. The following are example screens.

ERS_ERROR!

SUM = XXXX h

ADR = 1000000 STR = A0

Indicates that the program data is successfully loaded and the mobile light will blink green light.

Note 1) You can check if the loaded program data is correct or not by comparing the SUM values displayed on the PC side and the phone as shown on the screen 5. If both SUM values are the same, it means the correct program data has been loaded. Please check the SUM value quickly since this display will disappear very soon if using the Data cable.

Note 2) The screen 6 shows an example of one error occurred while in Flash erasing operation. “ADR” and “STR” only appear for Flash-oriented errors. Other errors are described latter in section 3. (see pages 2-22, 2-23)

SUM value is displayed few seconds after the program data has been successfully loaded. The value is displayed at "XXXX".

This screen appears when an error occurs and the mobile light will blink yellow. ADR: Address where the error occurs. STR: Flash Status information.

5) Completing the download

If the program data is successfully downloaded, [Download completed] message appears and then, the SUM value of the data loaded into the Flash is displayed. If the operation is not properly completed, the error message will appear. Refer to pages 2-22, 2-23 [Table of Error messages] for details of error messages.

[Caution!] After the downloading operation is ended, SUM value is displayed on the phone. You can check if the program data is successfully downloaded or not by comparing the SUM values displayed on the phone and the PC. Please check the SUM value quickly since this display will disappear very soon if using the Data cable (it will disappear in about 7 seconds). If both values are not the same, the program data may not be successfully downloaded. Please start downloading all over again.

1. Make sure to remove the AC charger from the Data cable. Otherwise it may cause the charging application to be activated and downloading operation cannot be operated properly.

2. Use a fully charged battery for the downloading operation.

3. If the battery is not charged enough, the downloading operation may not be completed. Make sure to charge the battery fully before downloading.

4. If the downloading operation is cancelled or interrupted due to an error condition, remove the battery once and then, start over the operation.

5. Start downloading after the phone has been properly turned off in order to clear the back-up RAM.

6. If you select “FileSystem Initialize” for the download, user’s data stored in the phone will be deleted. Care should be taken for this performance.

7. If the power saving mode is set on your PC, the download may fail depending on PCs. Please cancel the power saving mode when performing the download.

[If using “Communication Box Ver. 2G”:]

1. Switch on the Power button of the Box starting from No.10 to No.1 when “Sending Sync Byte…/Press Power Button” message appears. If the button 1 is switched on first, it results in failure of the downloading operation on phhones that are connected to the cable 2 to 10.
