Multi-operating system switching method of intelligent embedded equipment

The invention discloses a method for realizing multi-operating system selective start of intelligent embedded equipment. Firstly, multi-operating system partitions are divided for a user in a storage, an EEPROM (Electrically Erasable Programmable Read Only Memory) flag bit operating function and loading start functions written for each operating system are added to U-Boot, an operating system start menu is set in QT environment, an operating system is selected from the operating system start menu, so as to be started, the EEPROM flag bit operating function is invoked by the U-Boot, so as to read a flag bit of the operating system, and the loading start function of the operating system corresponding to the flag bit is invoked, so as to start the operating system. According to the method, a switching management system is independent of the U-Boot, the defect that the U-Boot cannot manage hardware in all directions is made up, and a more comprehensive interaction function can be provided, so that function extension is facilitated.
