AI Technical Summary

Technical Problem

In existing technologies, the firmware update process for extended cards affects business processing, has low management efficiency, lacks out-of-band management support, causes business interruption during the update, has insufficient security, lacks centralized management and auditing, and the update tools rely on the host operating system, resulting in complex management and easy errors.

Method used

Through collaborative management of BMC and MCU, resource isolation and out-of-band firmware updates of expansion cards are achieved. The firmware management platform is used for centralized management, and resource isolation technology is used to perform firmware updates without affecting business processing. Digital signature verification is used to ensure security, and expansion cards that support both hot and non-hot updates are supported.

Benefits of technology

It achieves independence between the expansion card firmware update process and business processing, improves management efficiency, ensures the security and integrity of the update process, supports hot updates of expansion cards without affecting business operations, and provides centralized management and auditing capabilities.

Abstract

The application discloses a firmware updating method of an expansion card and an electronic device. A controller receives a firmware updating task. A target firmware version number corresponding to a first expansion card is compared with a current firmware version number to obtain a comparison result. In a case where the comparison result indicates that the target firmware version number and the current firmware version number are inconsistent, a firmware image file of the first expansion card is written into a firmware storage space of the first expansion card, and a firmware loading instruction is sent to the first expansion card, so that the first expansion card loads the firmware image file. In the process of loading the firmware image file by the first expansion card, the current firmware version number corresponding firmware is used for service processing. After the first expansion card completes loading the firmware image file, the target firmware version number corresponding firmware is used for service processing. Resources used for loading the firmware image file by the first expansion card and resources used for service processing by the first expansion card are isolated.
