Application Deployment 9 - 5
• TCM (on development computer) to download the files.
Once these requirements are satisfied, the mobile computer can be upgraded by invoking IPL and navigating
the menus. See Sending the Hex Image Using IPL on page 9-10 for procedures on downloading a hex file to
the mobile computer.
Creating Hex Images
Terminal Configuration Manager (TCM) is an application used to customize flash file system partitions for the
mobile computer. The most common use is to create an application partition hex file that contains the
customer's application. TCM can also be used to load hex files to the flash memory of the mobile computer.
The program resident on the mobile computer that receives the hex file and burns it to the flash memory is
called Initial Program Loader (IPL).
The customization of partitions is controlled by TCM scripts. The scripts contain all of the necessary
information for building an image. The script is a list of copy commands specifying the files to copy from the
development computer to the partition.
TCM works with a pair of directory windows, one displaying the script and the other displaying the source files
resident on the development computer. Using standard windows drag and drop operations, files can be added
and deleted from the script window.
The DCP for MC17xxc50 includes scripts used by Motorola to build the standard factory installed Platform and
Application partitions provided on the mobile computer. The standard Platform partition contains drivers while
the Application partition contains demo applications and optional components. The standard TCM scripts can
be found in the following folder: C:\Program Files\Symbol Device Configuration Packages\MC17xxc50
v1.0\TCM Scripts.
The required processes for building a hex image in TCM include:
• Starting TCM
• Defining script properties
• Creating the script for the hex image
• Building the image
• Sending the hex image
• Creating a splash screen
• Flash storage.
Starting Terminal Configuration Manager
Click the Windows Start menu TCM icon (Symbol Device Configuration Packages, MC17xxc50) to start TCM.
The TCM window appears displaying two child windows: Script1 and File Explorer. The Script1 window
contains a newly created script and the File Explorer window contains a file explorer view used for selecting
files to be placed in the script.
NOTE Before creating a script to build a hex image, identify the files required (system files, drivers, applications,
etc.) and locate the files’ source directories to make the script building process easier.
