US 2025/0165607 A1 · ON-THE-FLY AND SECURE FIRMWARE UPDATES FOR CIRCUIT INTERRUPTERS

Abstract

Devices and methods for on-the-fly updates of circuit breakers during operation, the circuit breaker including a processor, a first memory including a first and second slot, and a second memory. In response to initialization, the processor stores a copy of a most recent firmware from the first or second slot in the second memory and executes the most recent firmware at the second memory. The firmware in the first or second slot may be a first firmware, and in response to obtaining a second firmware, the processor stores a copy of the second firmware in the other of the first and second slot. In response to a second initialization, the processor stores a copy of the second firmware from the other of the first slot and second slot in the second memory to enable execution of the second firmware, the second firmware being the most recent firmware.

Dependent claims

A system comprising:

a circuit breaker comprising:
a processor, and
a first memory including a plurality of slots comprising:
a first slot, and
a second slot;
and
a second memory;
wherein, in response to an initialization of the processor, the processor stores a copy of a most recent firmware obtained by the circuit breaker from one of the first slot and the second slot of the first memory in the second memory.

5 more elements

A circuit breaker device comprising:

a processor;
a non-volatile computer readable media comprising:
at least two slots,
wherein a first firmware is stored in a first slot or a second slot;
a volatile computer readable media;
wherein the processor is configured to perform operations comprising:
in response to a first initialization, the processor stores a copy of the first firmware from the first slot or the second slot of the non-volatile computer readable media in the volatile computer readable media and executes the first firmware in the volatile computer readable media,
in response to obtaining a second firmware, the processor stores the second firmware in the other of the first slot and the second slot not storing the first firmware, and
in response to a second initialization of the processor after obtaining the second firmware, the processor stores a copy of the second firmware from the other of the first slot and the second slot of the non-volatile computer readable media in the volatile computer readable media to enable execution of the second firmware;
and
wherein the first firmware is a previous firmware stored in the non-volatile computer readable media, and the second firmware is a most recent firmware stored in the non-volatile computer readable media;
wherein the processor stores the second firmware in an available slot of the first slot and the second slot of the non-volatile computer readable media such that execution of the first firmware is uninterrupted.
