Abstract

A method and apparatus for upgrading are provided. The method comprises: detecting whether a download flag of a second erasable editable logic device EPLD program is present in a spare information area for storing spare storage area state information, wherein the second EPLD program is an upgraded version of the first EPLD program, the first EPLD program is a version to be upgraded, and the sparestorage area is used for storing the second EPLD program; If the detection result is yes, the second EPLD program is put into trial operation. In the event of successful commissioning of the second EPLD program, the second EPLD program is activated. The invention can solve the problem that the EPLD program after upgrading is not guaranteed to be available after being activated in the related art,and the single board may not be able to run normally, meanwhile, the selection of the upgrading version is realized, and the effect of guaranteeing the reliability of the EPLD startup is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an upgrading method and device. Background technique [0002] At present, when a single board needs to upgrade the Erasable Programmable Logic Device (EPLD) program, the program is directly programmed into the EPLD through the low pin count LPC (Low pin count Bus) bus download. In ISF (In System Flash). This requires that when the EPLD program needs to be upgraded on the single board, the engineering personnel must go to the site to perform the operation. And many of our equipment boards are distributed in various places around the world. When multiple boards in multiple sites need to upgrade the EPLD program, it will consume a lot of manpower and material resources. In addition, when using the original upgrade method, it is often necessary to unplug the board, which may affect the normal operation of the entire network element and cause service interruption. And when the up...
