Abstract: A technology is directed to embedded device updates. In one example of the technology, a partition of a memory is atomically updated. The partition includes partition tables including a primary partition table and a back-up partition table. The partition tables include entries for the images included in the partition, and information associated with the images included in the partition. Atomically updating the partition of the memory includes writing an updated version to the partition. The written updated version is verified. An updated partition table is written to the back-up partition table. The updated partition table is written to the primary partition table. If it is determined that a power, or other, fault occurred while the primary partition table was being written, the primary partition table is overwritten with the back-up partition table.

Abstract: The disclosed technology is generally directed to embedded device updates. In one example of the technology, staging is performed for at least two priority groups, completing staging of each higher priority group before staging a lower priority group, including, for each priority group, the following actions. A list of install targets is generated for the priority group based on a list of software for installation in a memory and software present in the memory. A list of purge targets is generated for the priority group based on the list of software for installation in the memory and the software present in the memory. The install targets are downloaded to a backup partition of the memory. Updating of the software in the memory is caused based on the install targets. The purge targets are deleted from the memory. The install targets are deleted from the back-up partition.
