Abstract: This application is directed to managing firmware control data stored in a memory device of an electronic device. The electronic device obtains a current data descriptor map (DDM) corresponding to a current version of a firmware program, and identifies, in the memory device, a prior DDM and a prior control data structure corresponding to a prior version of the firmware program. Each of the prior and current DDMs maps a plurality of data descriptors to a plurality of locations in a respective control data structure. The prior control data structure stores a plurality of prior control data items identified by a plurality of prior data descriptors. A current control data structure is automatically generated for the current version of the firmware program based on the prior control data structure, the current DDM, and the prior DDM, and stores a plurality of current control data items identified by the data descriptors.

Abstract: A system and related method, including a first processor core, a second processor core and a control circuitry to receive requests to update existing firmware of the first processor core to a new firmware. The control circuitry loads existing firmware onto the second processor core and migrates data associated with the existing firmware on the first processor core to the second processor core. The control circuitry stops the transaction execution by the first processor core while causing the second processor core to execute transactions in place of the first processor core. The control circuitry restarts the first processor core, replaces the existing firmware on the first processor core with the new firmware, and migrates data of the existing firmware on the second processor core to the first processor core. The control circuitry stops the transaction execution of the second processor core and causes the first processor core to execute transactions.

Abstract: A method for updating a device includes receiving an instruction to update from a first configuration in the device to a second configuration, where a first heap memory allocated to the first configuration includes multiple first allocated memory blocks and corresponding first memory blocks metadata. The method also includes performing a warm reset, the reset including determining, based on the first memory blocks metadata, that when updating from the first configuration to the second configuration, data of at least one of the first allocated memory blocks should be persisted to a second heap memory allocated to the second configuration, and causing the device to update from the first configuration to the second configuration, where the update includes persisting, based on the first memory blocks metadata, the data of at least one of the first allocated memory blocks to a second heap memory allocated to the second configuration.
