Abstract

The invention discloses a multi-board-card automatic updating method and system based on internal storage sharing. The method includes the following steps that a component update host checks original update files stored in the component update host and determines the update files and a master control board card and / or slave board cards which correspond to components needing to be updated; the component update host sends the update files to the master control board card, and the components are updated through the master control board card, or the master control board card sends the update files to the slave board cards by sharing internal storage and the components are updated through the slave board cards. The components of the multi-board-card embedded system can be updated automatically, and manual intervention is reduced.

Description

technical field [0001] The invention relates to a multi-board embedded system, in particular to a component automatic update method and system in the debugging, production and upgrading process of a multi-board device with shared memory. Background technique [0002] Multi-board embedded systems are widely used in industries such as industrial control and rail transit. At present, the main control board and the files or software on the slave boards of the multi-board system are updated by the staff to update the master board or the slave boards one by one, and the board cannot be updated. Automatic update, so the update process is cumbersome and time-consuming. Contents of the invention [0003] The object of the present invention is to provide a method and system for automatically updating components of multiple boards based on memory sharing, so as to solve the problem of automatic component updating of the main control board and each slave board. [0004] In order to ...
