Abstract

The invention provides a washing machine firmware upgrading method and a washing machine. The upgrading method comprises the following steps of ST1, handshake confirmation; when the washing machine is in a power-on state, the washing machine establishes communication connection with a server, and judges and determines whether to enter an upgrading mode or not; ST2, firmware downloading; after confirming upgrading, MCU erases FLASH in the MCU, reads data in the server, verifies the data, writes the data into the FLASH after the data passes the verification, and quits the upgrading state after downloading is completed; ST3, firmware inspection; after the computer board is powered on, the downloaded firmware is checked, enabling the MCU to judge and confirm the integrity of the downloaded firmware and normal operation is ensured after confirming integrity. According to the washing machine firmware upgrading method and the washing machine, a computer board of the washing machine can be automatically upgraded according to needs, so that software functions of the computer board are expanded, performance is improved, faults are eliminated, and the upgrading cost of sold washing machine firmware is reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a washing machine firmware upgrading method and the washing machine. Background technique [0002] In many embedded product designs, an auxiliary micro control unit (Micro Control Unit, MCU) is required to cooperate with the main control central processing unit (Central Processing Unit, CPU) to realize the detection, control and preliminary information processing functions of some peripheral devices. In order to reduce the burden of the main control CPU, the auxiliary micro-control unit is a single-chip microcomputer. [0003] After all drum washing machines leave the factory, the firmware in the MCU of the computer board cannot be updated. This will lead to the following problems: [0004] 1. Manufacturers cannot promote better performance solutions to users' homes. [0005] 2. In the current growing Internet of Things environment, customers' functional requireme...
