Copyfiles; Non-Ffs Partitions - Motorola MC17 Product Reference Manual

9 - 24 MC17/MC17A/MC17T/MC17U Product Reference Guide
Platforms partitions folders. Take care when using Regmerge to make Registry changes. The DCP for
MC17xxc50 contains examples of .reg files.
NOTE Regmerge only merges the .reg files on cold boots. The merge process is skipped during a warm boot.
Typically, do not make modifications to registry values for drivers loaded before RegMerge. However, these
values may require modification during software development. Since these early loading drivers read these
keys before RegMerge gets a chance to change them, the mobile computer must be cold booted. The warm
boot does not re-initialize the registry and the early loading driver reads the new registry values.
Do not use Regmerge to modify built-in driver registry values, or merge the same Registry value to two files in
the same folder, as the results are undefined.

CopyFiles

Windows CE expects certain files to be in the Windows folder, residing in volatile storage. Windows CE
maintains the System Registry in volatile storage. CopyFiles copies files from one folder to another on a cold
boot. Files can be copied from a non-volatile partition (Application or Platform) to the Windows or other volatile
partition during a cold boot. During a cold boot CopyFiles looks for files with a .CPY extension in the root of the
Platform and Application FFS partitions (Platform first and then Application). These files are text files
containing the source and destination for the desired files to be copied separated by ">". The following example
from the file application.cpy is contained on the demo application partition included in the DCP for MC17xxc50.
It can also be obtained from the web site at http://supportcentral.motorola.com.
Files are copied to the Windows folder from the Flash File System using copy files (*.cpy) in the following
order:
\Platform
\Application
Example:
\Application\ScanSamp2.exe>\Windows\ScanSamp2.exe
This line directs CopyFiles to copy the ScanSamp2.exe application from the \Application folder to the
\Windows folder.

Non-FFS Partitions

Non-FFS Partitions include additional software and data pre-loaded on the mobile computer 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 mobile computer using files provided by Motorola. The
current OS partition on the mobile computer is included as part of the TCM installation package. Any
upgrades must be obtained from Motorola. This partition is mandatory for the mobile computer.
•
Splash Screen: a bitmap smaller than 16 kb (and limited to 8 bits per pixel) is displayed as the mobile
computer cold boots. To download a customized screen to display, see
page 9-18.
NOTE 8 bits per pixel only applies to splash screen images. Once Windows CE is running, the color density is
16 bits per pixel.
