Bootloader Update Voltage Check Prevents Corruption

The patent applies preliminary action by first checking the voltage level before initiating the bootloader update process. The system performs a voltage check to ensure sufficient power is available before writing to the protected storage area, preventing corruption from incomplete updates. This preliminary verification step ensures that the update process only proceeds when conditions are favorable, thereby maintaining reliability without significantly impacting update speed.

The patent applies self-service by implementing a voltage checking mechanism that is automatically performed by the controller itself during the bootloader update process. The controller monitors its own voltage level and autonomously determines whether to proceed with the update, eliminating the need for external complex verification systems. This self-monitoring approach maintains strong protection while keeping the updating process relatively simple.

The patent applies feedback by continuously monitoring the voltage level during the bootloader update process and using this information to control the writing operation. The system provides feedback about power availability to the update mechanism, allowing it to pause or cancel the operation if voltage drops below the required threshold. This feedback loop ensures complete and accurate writing when power is stable, while still allowing updates to be initiated at convenient times for the user.
