Embodiment Construction

[0017] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0018] During the startup process of embedded operating systems such as vxworks, some storage areas are not processed, and the size and address range of the available storage area of ​​the operating system can also be configured through the underlying software, so in practical applications, it can be configured through In the bottom layer software configuration process, make part of the storage area invisible to the operating system or use the uninitialized storage area of ​​the operating system to put the contents of the BOOT parameter area in this area. At the same time, the maintenance program for these important data is provided in the code of the BOOT system, so that the data in the BOOT startup parameter area can be effectively protected.

[0019] To realize the method for protecting the ...

Abstract

This invention discloses one software start parameter area method, which comprises the following steps: a, setting one pair of operation system invisual memory area to store current BOOT start parameters and correction values; b, in guiding process, judging whether the current BOOT start parameters correction values are accordant to the stored one, if yes, starting the current parameters; if not, then for step c; c, updating the current start parameters for memory on default parameters to compute new correction values for memory by use of the updated parameters.

Description

technical field [0001] The invention relates to a method for protecting data in a single-board start-up program (BOOT) parameter area, in particular to the preservation and maintenance of the BOOT parameter area when a single board is reset in embedded development. Background technique [0002] At present, the development and application of embedded systems are very extensive. In order to ensure that the software can be upgraded more conveniently, there are currently two processes for starting the software version on various boards. The first process is the normal startup of the BOOT boot system, and the second process is the normal operation of the version software. During the BOOT startup process, the operating mode of the version is determined according to the configuration data in the parameter area. The content of the BOOT parameter area is sometimes modified abnormally during the software debugging process. How to ensure that the data in the parameter area is legal an...
