Abstract
A method to update information including code and data in a non-volatile memory reliably and efficiently to avoid loss of information during the loading process and to minimize aircraft service downtime in an In-Flight Entertainment System (IFES). The non-volatile memory is partitioned into two sections: one section contains the currently valid information and the other is available for loading the new information. A section pointer is used to keep track of the currently valid section and to select the loading section. The new information is loaded to the selected loading section. A validation procedure is performed to determine if the loading is successful. When the loading of the new information is successfully completed, the section pointer is updated to point to the newly loaded section.
