Description<br />
Displayed if the FLM used does not support the flash memory that<br />
is installed on the board.<br />
Displayed if the modem firmware being uploaded is not in Motorola<br />
S3 format.<br />
Displayed if there is an error while either uploading or<br />
downloading. If this occurs, the transfer should be aborted, and the<br />
user should restart at step 5.<br />
Displayed if the transfer is aborted before it is finished. If this<br />
occurs, the user should restart at step 5.<br />
Displayed if the FLM is unable to erase the flash memory. If this<br />
occurs, the user should restart at step 5.<br />
Displayed if there was an error when uploading or downloading. If<br />
this occurs, the user should restart at step 5.<br />
Displayed if RTS-CTS flow control is not set. If this occurs, the<br />
user should restart at step 3.<br />
Displayed if the DTE has stopped the XMODEM transfer process<br />
before it is finished. If this occurs, the user should restart at step 5.<br />
Displayed if the user is attempting to upload a firmware that either<br />
not the same model (parallel, serial, etc.), crystal frequency, or size<br />
(1Mbit, 2Mbit, etc.) as the firmware that is currently on the board. If<br />
this occurs, the FLM will abort and not allow the user to continue.<br />
Displayed by the FLM at the completion of a successful upload or<br />
download then the modem will do a cold start.<br />
The uploader and downloader flash load modules (FLM) have several built in safety<br />
mechanisms to reduce the risk of a failed flash upload/download. The FLM will not allow<br />
a user to upload a firmware of different model (serial, parallel, etc.) or crystal speed than<br />
what is currently in the flash memory. Also, it will not allow the user to upload a<br />
firmware that is larger in size than the flash memory itself (e.g., a 2Mbit firmware onto a<br />
1Mbit flash memory). It will, however, allow the user to upload a firmware that is smaller<br />
in size than the flash memory, and it will program the firmware with the appropriate<br />
offset in order for the firmware to function properly. In the instance that there is a failure<br />
during the download or upload process, the modem will be in a “flash rescue mode”. In<br />
this mode, the modem will respond “OK” to all <strong>AT</strong> commands, but will only take action<br />
on the <strong>AT</strong>** command, so a new attempt to upload or download can be initiated. When<br />
the modem is in the “flash rescue mode” it will only be able to respond to <strong>AT</strong> commands<br />
if the DTE rate has not been changed since the last <strong>AT</strong>** command was successfully<br />
issued, even if the modem is powered off and on.<br />
