AI Technical Summary

Technical Problem

Existing technologies cannot accurately distinguish between cold and warm starts of devices without damaging external storage media or relying on dedicated hardware registers, making device status management and troubleshooting difficult.

Method used

A dedicated reserved area is set up in the high-end memory region. By combining the cyclic redundancy check algorithm and the warm start feature string, the cold and warm starts can be accurately identified through check value comparison.

Benefits of technology

It enables accurate identification of cold and hot starts of equipment, improves identification efficiency, reduces hardware wear and tear, and has good versatility and portability, supporting equipment operation and maintenance and fault location.

Abstract

This application discloses a method, apparatus, device, and medium for identifying cold and warm start flags of a device, relating to the field of system startup technology. The method includes: reserving a high-end memory area; reading currently started data from the high-end memory area and performing a verification calculation on the currently started data to obtain a verification value; comparing the verification value with a reference verification value; if the verification value matches the reference verification value, the current startup is determined to be a warm start; if the verification value does not match the reference verification value, the current startup is determined to be a cold start, and a preset warm start characteristic string is written into the high-end memory area. This method can accurately distinguish between cold and warm starts of a device.
