FAQ:
A. How do I select a correct baud rate?
The baud rate sets to 115200 for Download, Calibration, and Set E2P internally in dmtool.
Thus no matter which baud rate the user chooses in the configuration menu, their baud rate
is always 115200. Users can ignore the baud rate setting when execute these three
functions. But for EEPROM editor, and Service , their baud rates are changeable. If a user
selects baud rate as 19200, then the baud rate for these two options is 19200.
There are several situations may confuse users. After execution Set EEPROM Default or
Log Off, the target handset will change its baud rate to 19200. In order to communicate
with the MS, the dmtool?s baud rate should set to 19200. And if you run LOG ON
command in dmtool or Mobilog, the baud rate of the MS will change to 115200. So
remember to change baud rate to 115200 in configuration menu.
B. How do I select a correct flash-programmer file?
The flash programmer file (boot code file) plays an important role during a download
procedure. It takes care of programming flash ROM and is responsible for data
receiving/transmission. Flash programmer files for download vary as different MS models.
For Dual band, it uses AMD flash, thus the flash programmer files is r_AMDT.mot. In
some situation, this file is renamed as ?BootCode.mot? and users just need to click the
?change? button in configuration menu to select this file.
C. Why can?t I read data from EEPROM?
The reasons for this problem can divide into two parts:
1. Software setting problems:
a. The most common case is : database.bin file hasn?t been assigned or the baud rate
setting is incorrect in configuration menu. Choosing a wrong COM port also results
in this problem.
b. Has the MS completed the download process and set EEPROM default?
c. Solutions:
1. Assigned a correct database.bin file in configuration menu. If the target handset
is in Log On mode, then the baud rate should be 115200, else is 19200. Note that
if you get used to read EEPROM after an auto-calibration test without re-power
on the MS, the baud rate in the MS is 115200 at this time. Thus you should set to
115200 before auto-calibration starts.
2. Choose a correct COM port.
3. Download a new flash program into the MS and run Set E2P function to set
EEPROM default.
2. Hardware problems:
After making relative corrections for the software problems mentioned above, and
you still can?t read data from EEPROM, then do some further checks : In EEPROM
editor dialog, there is an Interface Debug status window. Is there any string in this
window? For example, you may observe sentences like ACK/NAK sent or
Unexpected MI. If there is nothing in this window, it is very possible the hardware
problems. Some common hardware problems are:
a. The RS232 connection between the MS and PC is unsuitable or the cable is bad.
b. Does your downloader require an external power supply?
c. Something shorts with the Accessory-in pins
D. Why can?t I download/upgrade programs into the handset?
