Abstract

A system for updating a multiple domain embedded system may include a processor that can identify a device associated with the embedded system and a driver that supports the device. The processor can determine a domain associated with the driver and a first configuration label of a first configuration of the multiple domain embedded system. The processor can also determine a second configuration label of a second configuration of the multiple domain embedded system, based on the first configuration label, an identification of the driver, and an identification of the device. Further, the processor can update the driver based on the second configuration label.

Claims4

Dependent claims

A system for updating a multiple domain embedded system, each domain configured for isolating executed applications from one another so that they do not affect each other, the system comprising:

a processor configured to operate in an automotive system;
and
memory communicatively coupled to the processor, the memory including:
instructions executable by the processor to identify an electronic device associated with the multiple domain embedded system;
instructions executable by the processor to identify a driver that supports the electronic device;
instructions executable by the processor to determine at least one domain associated with the driver;
instructions executable by the processor to determine a first configuration label of a first configuration of the multiple domain embedded system, the first configuration label including a first list of first files that are associated with the at least one domain;
instructions executable by the processor to transmit the first configuration label, an identification of the driver, and an identification of the electronic device to a configuration database, wherein the identification of the electronic device includes a device number, a type designation, and a vendor ID;
instructions executable by the processor to receive, from the configuration database, a second configuration label of a second configuration of the multiple domain embedded system, and a session identification as a unique identifier for updating firmware, where the second configuration label includes a second list of second files that are associated with the at least one domain;
and
instructions executable by the processor to update the driver based on the second files and the second file list,
where in response to detection by the processor of failure of the update of the driver, the processor further configured to roll back the driver based on the first files and the first file list and overwriting the second files with the respective first files;
and
a display configured to display a message notifying a user of an incompatibility of the second files and the at least one domain.

A method for updating a multiple domain embedded system, each domain configured for isolating executed applications from one another so that they do not affect each other, the method comprising:

identifying, by a first processor in an automotive system and the first processor being associated with a configuration manager, an electronic device associated with the multiple domain embedded system;
identifying, by the first processor, a driver that supports the electronic device;
determining, by the first processor, at least one domain associated with the driver;
determining, by the first processor, a first configuration label of a first configuration of the multiple domain embedded system, the first configuration label including a first list of first files that are associated with the at least one domain;
communicating, by the first processor, the first configuration label, an identification of the driver, and an identification of the electronic device to a second processor associated with a configuration database, wherein the identification of the electronic device includes a device number, a type designation, and a vendor ID;
determining, by the second processor, a second configuration label of a second configuration of the multiple domain embedded system, based on the first configuration label, the identification of the driver, and the identification of the electronic device, and where the second configuration label includes a second list of second files that are associated with the at least one domain;
and
communicating, by the second processor, a session identification as a unique identifier for updating firmware, the second files and the second configuration label to the first processor;
updating, by the first processor, the driver based on the second files and the second file list;
determining with the first processor that the update has failed, and the first processor rolling back the driver based on the first files and the first file list and overwriting the second files with respective first files;
and
displaying a message notifying a user of an incompatibility of the second files and the at least one domain.
