Abstract: In embodiments, a reset management circuit executes reset, configuration, and software runtime phases when a processing system is switched on, where one or more microprocessors start at respective start addresses. During the configuration phase, a circuit reads a boot record from a non-volatile memory and stores it to registers. The circuit sequentially reads data records of configuration data from the non-volatile memory and generates a write request for each data record to store the data of the respective data record to a second circuit with associated address data indicated in the respective data record. The processing system processes the boot record and boot configuration data provided by the second circuits to selectively start a predetermined microprocessor at a default start address or at a start address indicated by the boot configuration data, or start one or more microprocessors at respective start addresses as indicated by the boot record.

Abstract: A hardware configuration circuit can sequentially read data packets from a non-volatile memory. For a first data packet, the circuit is configured to store the configuration data and the address included in the data packet in the register, select a target configuration data client circuit as a function of the address included in the first data packet, transmit a first data signal that includes the configuration data included in the first data packet to the target configuration data client circuit, receive a second data signal that includes configuration data stored in the target configuration data client circuit and the address associated with the target configuration data client circuit, and compare the configuration data and address received from the target configuration data client circuit with the configuration data and address stored in the register.
