Problems solved by technology

[0004] However, in practical applications, the memory of optical network terminal equipment such as ONU is small, and the memory resources are quite tight; in this way, when the system program of the optical network terminal equipment is running and the system software is upgraded, the remaining memory space is small. It may not be possible to store the complete upgrade software image file in the memory of the optical network terminal device, thus making it difficult for the optical network terminal device to upgrade the system software, and it is easy to cause the upgrade to fail

Abstract

The invention discloses an optical network terminal equipment and a system software upgrade method thereof. The method includes allowing a system program of the optical network terminal equipment to calculate a CRC (cyclic redundancy check) value of a received data block, among data blocks, of an upgrading software image file and send starting information during timing to a watchdog; writing the data block into the FLASH, and sending resetting information to the watchdog during timing; writing the last data block in, after determining the CRC value of the data block being equal to a CRC value carried by the file, modifying upgrade state parameters into a upgrading state, and restarting the equipment; if the watchdog times out during timing, resetting and restarting the equipment; starting a bootstrap program after the equipment is restarted; allowing the bootstrap program to determine the upgrade state parameters, if the upgrade state parameters are in the upgrading state, loading the file to the memory, removing the CRC value, and obtaining upgrade software and operating; if the upgrade state parameters are upgraded, loading the system software to the memory and operating. Thus, system software can be upgraded in the small memory.

Description

technical field [0001] The invention relates to the communication field, in particular to an optical network terminal device and a system software upgrading method thereof. Background technique [0002] At present, fiber-to-the-home is becoming popular, and fiber-to-the-home has become the mainstream mode for operators to build access networks. In this way, the number of optical network terminal devices in the optical access network, such as optical network units (ONU, Optical Network Unit), is increasing significantly. In practical applications, system software upgrade is one of the common functions of optical network terminal equipment. By upgrading the system software of optical network terminal equipment, the needs of different operators or the different needs of the same operator can be met, and the functions of the system software of optical network terminal equipment can be continuously improved to adapt to the business and applications of operators continuous devel...
