1. Method for configuration of a module ( 205 ) in a modular data-processing system, the said module comprising temporal and hardware resources as well as an operating system ( 230 ) allowing a segregated running of at least two applications with the aid of at least one part of the said resources, this method being characterized in that it comprises the following steps, obtaining ( 305 ) at least one first configuration parameter of at least one part of the said resources of the said module, the said at least one first configuration parameter applying to a resource specific to the said operating system or a resource common to the said operating system and to at least one of the said at least two applications or to the said at least two applications; configuring ( 310 ) the said module according to the said at least one first parameter; obtaining ( 320 ) at least one second configuration parameter of at least one part of the said resources of the module, the said at least second configuration parameter applying to a resource specific to one of the said at least two applications; and, configuring ( 330 ) the said module according to the said at least one second parameter, in which the said at least one first and at least one second parameters are defined in separate configuration files.
