Embodiment Construction

[0017] The embodiment of the present application solves the cumbersome and cumbersome method of generating the burning mirror image by the Windows operating system interface software tool provided by the burner (or programmer) manufacturer in the prior art by providing a method based on the Linux system NAND FLASH master burning image. Difficult to operate, manual operation is easy to produce errors, skipping bad block mode batch programming is easy to cause technical problems such as data loss or incompleteness of sub-chips.

[0018] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application. , rather than limiting the technical solutions ...

Abstract

The invention belongs to the technical field of passive optical networks and discloses an NAND FLASH master slice burning mirror image achieving method based on a Linux system. The method is based on an embedded Linux system software development kit (SDK), adopts a LnuxC programming language and a Makefile and includes the following steps that a partition table is established in a Bootloader space to identify physical hardware NAND FLASH, and an MTD partition table is achieved in a Linux kernel driver; management of functions of partitions is achieved; generation of utility (software tools) of partition data mirror images is achieved; partition mirror image ECC codes are added through an achievement algorithm, and generation of two essential files, namely a partition table file and a data content file to be burned to NAND FLASH, of a burnable partition mode is achieved through a core algorithm; the utility achieved by adopting a C language algorithm are called from a Makefile to facilitate CPE software development and automatic generation of a burnable NAN DFLASH mirror image. The invention provides a corresponding achievement method for generating the burnable partition mode on a Windows operating system and providing the Linux operating system.

Description

technical field [0001] The invention relates to the technical field of passive optical networks, in particular to a method for realizing burning and mirroring of a NAND FLASH master chip based on a Linux system. Background technique [0002] In the passive optical network, the PON system consists of a central office optical line terminal (OLT: Optical Network Unit), an optical distribution network (ODN: Optical Distribution Network) and a user end optical network unit (OUN: OpticalNetwork Unit) to form a network topology. ; The service manages the upstream communication from multiple registered ONUs to the OLT via the central office OLT. In this case, the ONU (physical hardware and mirror) is connected to the OLT through the PON uplink port to form a master-slave structure. The OLT is connected to the network management system and service system (including broadband service, voice service and IPTV service platform) at the same time. (Northbound Interface) to realize the com...
