Abstract

L'invention concerne un premier procédé pour la mise à jour d'un microprogramme d'un système informatique, qui est intégré dans un appareil technique. L'appareil technique comprend un composant de mémoire volatil, par exemple une mémoire RAM, et comprend un composant de mémoire non volatil, par exemple une mémoire Flash, dans lequel est enregistré un progiciel de mise à jour de microprogramme, le progiciel de mise à jour de microprogramme contenant différents fichiers et des premières sommes de contrôle associées. Ledit procédé exécute les étapes suivantes dans l'ordre indiqué : - une remise sous tension (G), - un démarrage consécutif du système informatique (H) et - vérifier si un fichier indicateur existe dans le composant de mémoire non volatil (I). La présente invention concerne un second procédé pour la mise à jour d'un microprogramme du système informatique, qui est intégré dans un appareil technique. Ledit procédé exécute les étapes suivantes dans l'ordre indiqué : - une remise sous tension (G), - un démarrage consécutif du système informatique (H) et - une vérification si un fichier indicateur existe dans le composant de mémoire non volatil (I).
