I was not able to find "reboot reason", you probably refer to "reboot mode". Reboot Mode: Purpose: Dictates how the system should reboot (e.g., normal, recovery, bootloader). Usage: Provides instructions for the next boot mode. Scenario: Utilized in planned reboots or software-triggered reset scenarios. PSCR (Power State Change Reasons): Purpose: Logs the reason behind a power state change (e.g., voltage drop, over-temperature). Usage: Used for rapid logging and post-event analysis, potentially informing automatic decision-making in subsequent boots. Scenario: Critical in abrupt power-down situations where immediate, detailed decision-making is not possible.
