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.
