Abstract

Des modes de réalisation de la présente invention concernent un procédé et un appareil de traitement d'application et un support de stockage. Dans le mode de réalisation de la présente invention, une première application dans un dispositif de stockage d'un appareil intégré est remplacée par une seconde application et un second chargeur d'amorçage dans un micrologiciel de mise à niveau. La seconde application stocke une adresse de début du second chargeur d'amorçage. Le second chargeur d'amorçage est acquis en fonction de l'adresse de début du second chargeur d'amorçage, et un premier chargeur d'amorçage dans le dispositif de stockage est remplacé par le second chargeur d'amorçage, réalisant ainsi une mise à niveau d'une application et d'un chargeur d'amorçage. La seconde application comprend une région d'en-tête. Si la taille du second chargeur d'amorçage est supérieure à la taille du premier chargeur d'amorçage, le second chargeur d'amorçage peut occuper la région d'en-tête de la seconde application, de telle sorte que le second chargeur d'amorçage n'écrase pas un code exécutable effectif de la seconde application, permettant ainsi un fonctionnement normal de la seconde application mise à niveau, et permettant ainsi un fonctionnement normal de l'appareil intégré mis à niveau.
