2results about How to "Improve upgrade speed" patented technology

The invention provides a flexible mirroring FLASH partition upgrading system and method for an embedded system. The system comprises an upper computer and a lower computer, the upper computer serves as a mirror image self-adaptive manufacturing tool, participates in compiling of new function software, and generates an integer mirror image file, namely a new function mirror image; the lower computer uses a built-in FLASH hardware memory as an NVM (Non-Volatile Memory) based on an MCU (Microprogrammed Control Unit); the upper computer and the lower computer interact through a high-speed communication protocol, when new function software of a system is updated, the upper computer automatically calculates key parameters of a mirror image and pre-embeds the key parameters into a new function mirror image, and after the lower computer receives an upgrading request and mirror image data, the data is adaptively written into a specified address FLASH space by erasing FLASH and programming data. According to the method, the embedded mirror image size can be flexibly modified, the FLASH erasing and copying data volume can be adaptively adjusted, the functional area jump address can be adaptively recognized, the upgrading speed can be improved, and the expansibility of embedded function upgrading is enhanced.

This application discloses a firmware upgrade method, device, storage medium, and program product, relating to the field of server technology. It ensures module storage alignment between versions through fixed-length module design, eliminating the impact of address drift; generates reversible difference data through XOR operations, enabling the same differential packet to support upgrades and rollbacks, simplifying version management and reducing storage overhead; verifies the compatibility of the differential packet with the device firmware structure before upgrades through layout verification of the metadata area and verification area, preventing accidents caused by version errors; and performs lightweight operations only on the difference bits through in-situ bit-level modification, reducing resource consumption and improving upgrade efficiency. These features work synergistically to reduce data volume and alleviate network pressure during transmission, enhance operational security during verification, and achieve efficient upgrades and reliable rollbacks during execution. It is suitable for weak network environments, large-scale concurrent upgrades, and high-reliability embedded firmware management scenarios.
