Problems solved by technology

[0006] 1. The memory dump function must run in the memory. The existing solution does not impose any restrictions on the memory for running the memory dump function, which may cause the memory running the memory dump function to overwrite the memory information to be collected, making the collected Incomplete memory information
[0007] 2. Since the collected memory information is stored in the local storage device, the computer system must support the file system
In this way, for embedded systems with small file system storage resources, only part of the memory information can be stored, so that the collected memory information is incomplete; but for embedded systems without file systems, this solution cannot be applied

Embodiment Construction

[0052] The core idea of ​​the present invention is to add a memory collection function to the boot software, and after the device is restarted, run the boot software, load the memory collection function to a storage area not occupied by memory information, and run the memory collection function to collect memory information.

[0053] In the embodiment of the present invention, the memory collection function may be loaded into a secondary cache (Cache) or free memory or unallocated original memory or reserved memory dedicated to loading the memory collection function.

[0054] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Abstract

The invention discloses a method for acquiring memory information and a unit thereof. The method comprises the following steps: a memory acquisition function is added to boot software, after an equipment system is restarted to operate the boot software, the memory acquisition function is loaded to a memory area which is not occupied by the memory information, and then the memory acquisition function is operated to acquire the memory information. The method and the unit ensure the integrity of the acquired memory information.

Description

technical field [0001] The invention relates to the technical field of memory analysis, in particular to a method and a unit for collecting memory information. Background technique [0002] In the application, the system on the core dedicated equipment has very high requirements for stability. If the system freezes or restarts, it is a major accident that must be resolved as soon as possible. However, such problems are often very difficult and have great individual differences. Therefore, it is necessary to provide general, rapid and effective analysis and diagnosis methods. [0003] Currently, the memory analysis method is usually adopted. The general idea of ​​this method is: collect the memory information before the system freezes or restarts, analyze the memory information such as: task stack, global variables, various data structures, etc., to locate the cause of the fault. The key to the memory analysis method is the collection of memory information. [0004] The ex...
