Using Flash to Upgrade Modem Firmware
The linear flash memory downloader in the modem firmware allows flash
memory connected to the modem external memory bus to be upgraded
with revised modem firmware. This process transfers (uploads) the
upgraded modem firmware (data) from the host computer to the modem
which transfers (downloads) the data to the flash memory device. Note
that this downloader function must be provided in modem MCU firmware
initially installed in external flash memory, i.e., the downloader does not
support the programming of blank flash memory. Programming the flash
memory device is a two-step process:
A. When the AT** command is issued, the modem firmware boot loader
is invoked and you will first load a flash load module (FLM) into the
modem’s RAM. The FLM contains the programming algorithm for the
flash memory device being programmed and any messages that may
be sent during the load process.
B. Load the new modem firmware which the FLM will then program into
the flash memory device.
Flash Procedure:
1. Put the FLM file and the new modem firmware file (e.g., V1400DS.S37)
in an appropriate directory on the computer’s hard disk.
2. Configure the communications application program for a DTE rate of
between 9600 bps and 57600 bps and RTS/CTS flow control. A load
at 57600 bps will take approximately 2 minutes; a load at 19200 bps
will take approximately 6 minutes.
3. Check the modem for response by typing AT.
4. Initiate the download process using the AT**n command, where:
