Patent number: 9274789Abstract: An in-application upgrade method is used for optical module firmware not breaking a service. A storage area for internal programs of an optical module is divided into two areas which are respectively used for storing upgrade and application programs, and is divided into an area for backing up an interrupt vector table of a Boot program. An upper computer is in communication with the optical module. The interrupt vector table is switched, and the jump between the Boot program and the application program is achieved. The method includes extracting the contents of firmware, entering a download mode and updating the firmware. The original firmware is erased, and new firmware is written. An application mode is entered, the upper computer sending an exit command from the download mode. The upgrade program exits and a new application program is executed. The optical module operates normally without interruption.Type: GrantFiled: December 17, 2012Date of Patent: March 1, 2016Assignee: WUHAN TELECOMMUNICATION DEVICES CO., LTD.Inventors: Tao Yuan, Xianghong Yu, Xuguang Chen
