Background In the technical field of firmware upgrade of embedded devices, the existing scheme mainly faces the following limitations: Firstly, the full-scale upgrading mode needs to transmit a complete firmware packet, which often results in excessively long transmission time in industrial application scenes with limited network bandwidth, and occupies a large amount of equipment storage space. This feature makes it difficult to adapt to small embedded devices (e.g. MCU (microcontroller) based platforms) where storage resources are scarce. The traditional incremental upgrade scheme still has various defects that a) a storage management strategy is stiff, a fixed block erasing mode is generally adopted, dynamic adjustment cannot be carried out by combining hardware characteristics (such as a minimum erasing unit and a block structure) of external Flash, storage resource waste or write failure is easy to cause, b) a communication protocol is single in design, data transmission efficiency is low if only a TCP protocol (transmission control protocol) is relied on, reliability of a control instruction is insufficient and upgrade process interruption is easy to cause if only a UDP protocol (user datagram protocol) is adopted, c) a verification mechanism is weak, simple verification is generally carried out only at a transmission layer, double guarantee of a hardware layer (such as instant read-back verification after Flash) writing is lacked, and storage medium faults are difficult to effectively detect. In addition, the existing upgrading flow generally lacks effective state machine management, once upgrading is interrupted, progress cannot be traced accurately, and equipment is easy to enter a brick state (namely, the equipment cannot be started normally). Finally, the current scheme has the defects in compatibility and suitability, is difficult to flexibly adapt to the differences (such as Flash capacity, network interface performance and the like) of embedded devices of different types on hardware, and limits the popularization and application range.
