The following messages may occur during the uploading process:
Message
Description
Device not supported
Displayed if the FLM used does not support the flash
memory that is installed on the board.
Wrong S37 format
Displayed if the modem firmware being uploaded is not in
Motorola S3 format.
Record error
Displayed if there is an error while either uploading or
downloading. If this occurs, the transfer should be aborted,
and the user should restart at step 5.
Download abort
Displayed if the transfer is aborted before it is finished. If
this occurs, the user should restart at step 5.
Erase fail
Displayed if the FLM is unable to erase the flash memory.
If this occurs, the user should restart at step 5.
Download error, Re-Load
Displayed if there was an error when uploading or
downloading. If this occurs, the user should restart at step
5.
Error, No H/W flow ctl
Displayed if RTS-CTS flow control is not set. If this occurs,
the user should restart at step 3.
DTE timeout
Displayed if the DTE has stopped the XMODEM transfer
process before it is finished. If this
occurs, the user should restart at step 5.
Code doesn’t match
hardware
Displayed if the user is attempting to upload a firmware
that either not the same model (parallel, serial, etc.),
crystal frequency, or size (1Mbit, 2Mbit, etc.) as the
firmware that is currently on the board. If this occurs, the
FLM will abort and not allow the user to continue.
Device successfully
programmed
Displayed by the FLM at the completion of a successful
upload or download then the modem will do a cold start.
The uploader and downloader flash load modules (FLM) have several built in safety mechanisms to
reduce the risk of a failed flash upload/download. The FLM will not allow a user to upload a
firmware of different model (serial, parallel, etc.) or crystal speed than what is currently in the flash
memory. Also, it will not allow the user to upload a firmware that is larger in size than the flash
memory itself (e.g., a 2Mbit firmware onto a 1Mbit flash memory). It will, however, allow the user
to upload a firmware that is smaller in size than the flash memory, and it will program the firmware
with the appropriate offset in order for the firmware to function properly. In the instance that there is
a failure during the download or upload process, the modem will be in a “flash rescue mode”. In this
mode, the modem will respond “OK” to all AT commands, but will only take action on the AT**
command, so a new attempt to upload or download can be initiated. When the modem is in the
“flash rescue mode” it will only be able to respond to AT commands if the DTE rate has not been
changed since the last AT** command was successfully issued, even if the modem is powered off
and on.
10.8.2 *B - Display Blacklisted Numbers
This command requests the modem to return a list of blacklisted numbers to the DTE. The format of
the response is shown by the example below. Permanently forbidden numbers as defined by country
requirements will not appear on this list. If no numbers are blacklisted, only the OK result code is
issued.
