Abstract

The invention discloses a firmware upgrade protection method. The method includes the following steps: receiving a firmware upgrade command; reading the firmware to be upgraded based on the firmware upgrade command; identifying the firmware identification number preset in the firmware to be upgraded; judging whether the firmware identification number is It corresponds to the target chip; when the firmware identification number corresponds to the target chip, the firmware to be upgraded is upgraded. The invention can judge whether the firmware to be upgraded is the firmware to be upgraded before the firmware is actually upgraded, and only when the firmware to be upgraded is the firmware to be upgraded, the firmware to be upgraded is upgraded, effectively avoiding firmware upgrade errors. The invention also discloses a firmware upgrade protection system.

Description

technical field [0001] The present invention relates to the technical field of firmware, and more specifically, to a firmware upgrade protection method and system. Background technique [0002] In the embedded field, almost all products involve the operation of firmware upgrade. A product may have more than one chip, and the chips may all be the same model with different firmware versions. When upgrading the firmware of these chips, it may cause confusion due to too many firmwares. For example, firmware A is upgraded to firmware B; the final result is that the entire system cannot work normally, and if you want to upgrade again, Because the firmware of the corresponding chip is wrong, it cannot run normally and cannot respond to the upgrade command, so the chip can no longer be upgraded. It can only be re-programmed with a programmer, which will cause serious losses. [0003] At present, there is a way to store two images in the firmware flash memory of the chip to solve t...
