Abstract

The application provides a method and device for updating configuration data. The method comprises following steps: examining whether a CF card is provided with a file lock when a master control board is started; examining whether a configuration data package is present on the CF card when the file lock exists on the CF card; updating assigned configuration data on the CF card according to configuration data decomposed by the configuration data package; and deleting the file lock when determining that assigned configuration data on the CF card is finished updating. The method and device for updating configuration data have following beneficial effects: correct update of configuration data on the CF card can be finished when power failure or fault emerges during the process of updating configuration data on the CF card.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for updating configuration data. Background technique [0002] In an embedded device, a CF (Compact Flash, compact flash memory) card with low power consumption, stable performance and no data loss when power off is usually used as a storage device. Usually the CF card exists on the main control board. In a computer system, since the access speed of the CF card is much lower than that of the internal memory and processor, the data that needs to be written to the CF card will be temporarily stored in the internal memory, and then periodically written to the CF card. When the configuration data on the CF card is updated, the updated configuration data will be temporarily stored in the internal memory, and then written to the CF card periodically to complete the update of the configuration data on the CF card. [0003] During the process ...
