The invention discloses an automatic remote firmware upgrading method and system for small-storage-capacity equipment and a chip, belongs to the field of remote firmware upgrading, and aims to solve the problems that the storage space of the equipment is limited and remote upgrading of the small-storage-capacity equipment is not facilitated due to the fact that a firmware program to be upgraded needs to be backed up in an existing remote firmware upgrading method. According to the upgrading method, firmware verification is comprehensive in the upgrading process, safe operation of firmware is guaranteed to achieve smooth upgrading, equipment does not need to back up firmware programs in the remote upgrading process, if upgrading exception occurs in the upgrading process, a special upgradingmode is automatically started, firmware remote downloading is conducted, the original firmware in the flash of the equipment is covered by the downloaded firmware, checking is performed again, and upgrading is performed. The method and the device are mainly used for remotely upgrading the firmware.
Description
technical field [0001] The invention belongs to the field of remote firmware upgrade. Background technique [0002] Firmware upgrade refers to upgrading the embedded firmware of the hardware device. Firmware upgrades can improve machine functions, enhance machine stability, and patch machine vulnerabilities. Since the higher version often fixes some bugs (vulnerabilities) of the lower version, the upgraded version that has undergone a firmware upgrade will generally have better performance than the original version, get optimized results, and users can also have a better experience. [0003] Since the hardware devices upgraded in the firmware upgrade are often not smart enough, it is difficult to control the same way as the software upgrade. After the new version is released, the version information is automatically detected through the smart terminal, and the update command is received from the outside, and then the update is performed. . Therefore, when the hardware dev...
