Abstract: Embodiments of the present application provide an online program updating method, including: receiving an external command, acquiring an updated program file, and storing the updated program file into the backup area through a program in the application area, where the external command includes the updated program file, and running the updated program file when a program counter jumps to the backup area. This solution, after the program counter jumps to the backup area, runs the updated program file, thereby providing power continuously while updating the online program and improving the reliability of the power supply system.
