Copying system images from a network server to Flash memory

As mentioned above the system image file contains the application software that runs SmartWare; it is loaded
in the flash memory at the Patton Electronics Co. factory. Since most of the voice and data features of the
SmartNode are defined and implemented within the application software, upgrading to a new release might be
necessary if you want to have additional voice and data features available. A new system image file has to be
stored permanently into the flash memory of your SmartNode to be present when booting the device.
Since the system image file is preloaded at the Patton Electronics Co. factory, you will only have to download
new SmartWare application software if a major software upgrade is necessary or if recommended by Patton
Electronics Co. Under normal circumstances downloading a system image file should not be needed.
Downloading a new system image file means storing it permanently at a defined location within the Smart-
Node flash memory. To store the system image file a special download script file has to be used. This script file
defines how the system image file is to be handled and where it is to be stored. You cannot download any sys-
tem image file without an appropriate script file.
Each line in script file is a command for the CLI of your SmartNode. To download a system image file, which
will replace the currently running SmartWare application software, a script file with only one command is nec-
essary.
Comment lines must have a hash character # in column one and can appear anywhere in the script file. Com-
ment lines contain information for administrators or operators who maintain or use the script file.
The following example shows a script file used to download a system image and command line syntax defini-
tion file from a TFTP server.

#the next line deletes the whole embedded file system

Note
The script file includes a 32-bit CRC on the last line, displayed as four char-
acters when seen in an ordinary text editor. Do not delete the line containing
the CRC entry or the download will fail!
The script file is downloaded with the copy commands. The copy command source defines the TFTP path to
the script file and the target is set use the script parser. After downloading the script file the system image file
and command line syntax definition file download is started automatically.
