Abstract

The present disclosure relates to an electronic device, such as a system on chip, that may perform firmware updates based on user consent. The system on chip includes a nonvolatile memory (NVM), a main processor, a security NVM, and a security processor. The nonvolatile memory (NVM) stores first firmware and a user permission indicator. The main processor Loads the first firmware to boot a security processor. The security NVM contains first version information. The security processor compares version information of the first firmware to the first version information based on the user permission indicator and executes the first firmware in response to the matching of the comparison result. In some examples, the security processor is implemented on the same chip as the main processor.
