Non-Ffs Partitions; Downloading Partitions To The Wearable Terminal - Motorola WT4070 Integrator Manual

7 - 22 WT4070/90 Wearable Terminal Integrator Guide

Non-FFS Partitions

Non-FFS Partitions include additional software and data pre-loaded on the wearable terminal that can be
upgraded. Unlike FFS Partitions, these partitions are not visible when the operating system is running. They also
contain system information. Non-FFS partitions include the following:
•
Windows CE: The complete Windows CE operating system is stored on Flash devices. If necessary, the
entire OS image may be downloaded to the wearable terminal using files provided by Zebra. The current OS
partition on the wearable terminal is included as part of the TCM installation package. Any upgrades must be
obtained from Zebra. This partition is mandatory for the wearable terminal.
•
Splash Screen: a bitmap smaller than 16 kb (and limited to 8 bits per pixel) is displayed as the wearable
terminal cold boots. To download a customized screen to display, see
7-19.
NOTE 8 bits per pixel only applies to splash screen images. Once Windows CE is running, the color density is 16
bits per pixel.
•
IPL: This program interfaces with the host computer and allows downloading via cradle or serial cable any or
all of the partitions listed above, as well as updated versions of IPL. Use caution downloading updated IPL
versions; incorrect downloading of an IPL causes permanent damage to the wearable terminal. IPL is
mandatory for the wearable terminal.
•
Partition Table: Identifies where each partition is loaded in the wearable terminal.

Downloading Partitions to the Wearable Terminal

TCM is used to specify a hex destination file for each partition and download each file to the wearable terminal.
This download requires a program loader stored on the wearable terminal. The wearable terminal comes with a
program loading utility, Initial Program Loader (IPL), stored in the wearable terminal's write-protected flash.
