A memory mirroring card debugging method and system thereof

Abstract

The invention discloses a memory mirroring card debugging method and system thereof, comprising: after inserting a memory bar into the memory mirroring card to be tested, the processor of the memory mirroring card to be tested sends basic commissioning instructions to perform basic functions of the memory mirroring card to be tested Commissioning: After the basic commissioning results meet the predicted basic commissioning requirements and the gold finger interface of the memory mirroring card to be tested is inserted into the memory mirroring card on the simulated computer side, the processor of the memory mirroring card on the simulated computer side sends a basic commissioning command for reading and writing, To call its own preset read-write commissioning program to perform basic read-write commissioning of the memory mirror card to be tested; after the read-write commissioning results meet the read-write commissioning requirements and the memory mirror card to be tested is inserted into the host, the host generates sending and receiving commissioning commands , to perform data sending and receiving commissioning on the memory mirroring card to be tested until the sending and receiving commissioning results meet the preset sending and receiving commissioning conditions. The test process of the present invention can be set according to requirements, has less limitations, and the test reliability after being inserted into the host is higher.

Description

technical field [0001] The invention relates to the technical field of memory hardware debugging, in particular to a memory mirroring card debugging method and system thereof. Background technique [0002] Memory is one of the most important components in a computer. Whether the system can run stably depends on the reliability of the memory. In order to improve the reliability of memory, memory mirroring is the most commonly used method. The basic principle of memory mirroring is that there are two or more DDR (Double Data Rate, double-rate synchronous dynamic random access memory, a memory specification) memory modules at the same time in the system. Once the memory module of one channel fails (or data transmission error), the memory controller will transfer the data to the memory module of another channel to avoid service interruption, thereby improving the reliability of the system and ensuring the function of the computer normal operation. The memory mirroring card is ...

Problems solved by technology

When a brand-new memory mirroring card with untested functions is directly inserted into the memory slot of the mainboard, because the means for debugging the memory mirroring card in the host are limited, and the staff usually can only use the existing test in the host. Therefore, when an untested memory mirroring card is directly inserted into the motherboard of the host, many tests cannot be completed, and the testing process is limited, and when When the system is down or the data is wrong, it is impossible to quickly locate the fault
