Method and system for restoring custom user configuration settings across a host application download
First Claim
1. A method of downloading an application into an erasable memory of a data reader, comprising the steps of:
- converting operational parameters of the data reader from an existing configuration structure into a common configuration structure;
storing the operational parameters having the common configuration structure in a secure memory location within the data reader;
downloading the application to the erasable memory of the data reader;
converting the operational parameters from the common configuration structure into a new configuration structure corresponding to the application;
storing the operational parameters having the new configuration structure in a non-volatile memory of the data reader.

Abstract
A method of preserving user configuration settings across a host application download to a device, such as a data reader, having a Flash memory, or other erasable memory. The existing user configuration settings of the device are stored in a secure, non-Flash, area of the device, using a common configuration description language (CDL), during the host download of the new system application, such as a firmware upgrade. The secure area is a non-volatile storage area, such as an EEPROM. After the new application is downloaded, the user configuration settings are translated into the new application'"'"'s internal configuration structure and stored in the system'"'"'s EEPROM, or other non-volatile memory, without the need for reprogramming. Accordingly, the original preferred user configuration settings are preserved across the application download, and may be used in conjunction with the new application.

10. A data reading system having custom configuration settings comprising:
-
a data reader having (1) an erasable memory for storing an application, (2) a non-volatile, non-Flash memory for storing custom configuration settings, the custom configuration settings being in a first configuration language, and (3) a secure data storage area therein;
a host in communication with the data reader for downloading an application to the erasable memory of the data reader;
software for (1) converting the custom configuration settings from the first configuration language into a common configuration description language, (2) storing in the secure data storage area the custom configuration settings in the common configuration description language, (3) converting the custom configuration settings from the common configuration description language into a second configuration language corresponding to the application downloaded from the host, and (4) storing the custom configuration settings in the second configuration language into the non-volatile, non-Flash memory. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A system having custom operational parameters and application download capabilities to a Flash-based device, comprising:
-
a device having a Flash memory and a non-voaltile, non-Flash memory contained therein;
a secure data storage area within the device for storing custom operational parameters in a common configuration structure;
a host in communication with the device for downloading an application to the Flash memory of the device;
software for (1) converting the custom operational parameters from a first configuration structure into the common configuration structure, (2) storing in the secure data storage area the custom operational parameters in the common configuration structure, (3) converting the custom operational parameters from the common configuration structure into a second configuration structure corresponding to the application downloaded from the host, and (4) storing the custom operational parameters in the second configuration structure into the nonvolatile, non-Flash memory. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
