Problems solved by technology

[0003] During this process, problems that may arise include: there is a problem with the new firmware or the new firmware does not match the device, so that the upgraded device cannot start normally. From the appearance, there is no response after the device is powered on. There is a phenomenon that the device cannot be started; another is that the flash memory block storing the firmware on the device is damaged. When the device is started, it cannot normally read the code from this address for execution. This problem will also make the device unable to start again
[0006] It can be seen from the above that the problems existing in the current processing method are: when a problem occurs, the user cannot analyze and solve it by himself; in the stage of returning to the factory for maintenance, manual participation is required throughout the process

Abstract

The invention discloses a firmware upgrading method and device, which are used for firmware upgrading. By adopting the firmware upgrading method and device provided by the invention, when a first wrong firmware is upgraded, or after a wrong that a flash memory region storing the third firmware is abnormal to cause that the system can not normally run occurs, a fourth correct firmware externally stored in the storage device is obtained, and the fourth firmware covers the third firmware in an original equipment flash memory, thus the problem that equipment can not be started caused by upgrading failure is solved, no manual intervention is required, the time cost is lowered, and the user experiment is improved.

Description

technical field [0001] The invention relates to the field of firmware upgrading, in particular to a firmware upgrading method and device. Background technique [0002] During the life cycle of embedded devices such as cameras, firmware upgrades are used to update and maintain the devices. After the upgrade is successful, the firmware is generally stored in a specific location in the flash memory of the device. [0003] During this process, problems that may arise include: there is a problem with the new firmware or the new firmware does not match the device, so that the upgraded device cannot start normally. From the appearance, there is no response after the device is powered on. There is a phenomenon that the device cannot be started; another is that the flash memory block storing the firmware on the device is damaged. When the device is started, the code cannot be read from this address for execution. This problem will also make the device unable to start again. [0004...
