Computer system memory detection method and system independent of operating system

Abstract

According to the computer system memory detection method and system independent of the operating system, a memory detection program is written into a computer system memory through JTAG equipment, so that the computer system memory can run in the initial starting stage of the computer system, namely, the execution of a solidified code segment of the computer system is finished after basic hardware is initialized and before a bootloader runs; and the memory is circularly detected for multiple times in three modes of writing 0 and 1 into the memory and writing the processed address value and performing backward reading. The memory detection method provided by the invention can be applied to a scene that a computer operating system cannot work or does not have an operating system, can quickly and accurately detect whether the problem of connection of the address line and the data line exists in the memory equipment or not, and can detect the problems of constant 0, constant 1 and short circuit of the address line and the data line of the memory equipment.

Description

Technical field [0001] The present invention relates to the field of computer memory detection, and more particularly to an efficient, reliable memory detection method, and more particularly to a computer system memory detection method independently of the operating system. Background technique [0002] Since the computer system is currently used as a memory device such as SDRAM, DDR as a storage device. Therefore, the detection of memory ensures that the integrity of memory plays a particularly important role in the development and commissioning of the computer system. Most of the primely mature technologies are used in memory detection applications applied to the operating system level, which cannot detect memory issues normally without operating system or operating systems. This requires a memory detection method that can be independent of the operating system. And most of the existing memory detection methods are to see if there is a problem with memory devices by writing som...

Problems solved by technology

[0003] The technical problem to be solved by the present invention has two points, namely, the existing memory detection program cannot completely detect the memory availability of the computer system in a bare-metal environment independently of the operating system, and the existing memory detection method is inefficient and has Detect unreliable factors such as blind spots
