Embodiment Construction

[0020] In order to improve the stability and reliability of the communication equipment, the embodiment of the present invention provides an online upgrade method of CPLD, in which the master and slave CPLD are used in the service board, and when the upgrade of the master CPLD fails, the upgrade is completed by the slave CPLD The startup configuration of the processor CPU, and the real upgrade of the CPLD through the master-slave mode, thus improving the reliability and stability of the system.

[0021] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] figure 1 The online upgrade method of the CPLD that the embodiment of the present invention provides, the method may further comprise the steps:

[0023] S101: The processor of the service board obtains a CPLD file for upgrading, and according to the obtained file, upgrades the file to be upgraded corresponding to the main CPLD on the service board and...

Abstract

The invention discloses an on-line upgrade method of complicated programmable logical devices, which is used for solving the problem that the reliability and the stability of communication equipment are influenced because of the upgrade mistake or the upgrade failure of CPLDs in the prior art. In the method, an obtained CPLD file used for upgrade is adopted to upgrade a file which corresponds to a main CPLD and is to be upgraded, a service single plate is restarted, and a processor finishes the starting configuration by an auxiliary CPLD when the restarting of the main CPLD is unsuccessful in the starting process of the service single plate. The embodiment of the invention also provides an on-line upgrade device of the CPLDs. Because the embodiment of the invention adopts the matching of the main CPLD and the auxiliary CPLD to finish the on-line upgrade of the CPLDs, the problem that the reliability and the stability of the communication equipment are influenced because of the upgrade mistake or the upgrade failure in the on-line upgrade process of the CPLDs is effectively avoided.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an online upgrading method and device for a complex programmable logic device (Complex Programmable Logic Device, CPLD). Background technique [0002] CPLD has the advantages of flexible programming, high integration, short design and development cycle, wide application range, advanced development tools, low design and manufacturing costs, and strong confidentiality. It has become an indispensable part of electronic products, so it is widely used in product During prototyping and product production. At the same time, the CPLD can also be upgraded online, so when a new function is added to the CPLD of the circuit system or the CPLD fails, it can be solved by upgrading. [0003] Logic devices such as CPLD are generally located on the service board. During the CPLD upgrade process, the business logic devices on the service board can be divided into: CPLD for interface contro...
