A memory mirror image card debugging method and system

Abstract

The invention discloses a memory mirror image card debugging method and system, and the method comprises the steps: enabling a processor of a to-be-tested memory mirror image card to send a basic debugging instruction to carry out the basic function debugging of the to-be-tested memory mirror image card after a memory bank is inserted into the to-be-tested memory mirror image card; after the basicdebugging result meets the prediction basic debugging requirement and the golden finger interface of the memory mirror image card to be tested is inserted into the memory mirror image card of the analog computer end; a processor of the memory mirror image card of the simulation computer end sends a read-write basic debugging instruction to call a self-preset read-write debugging program to carryout read-write basic debugging on the memory mirror image card to be tested; and after the read-write debugging result meets the read-write debugging requirement and the to-be-tested memory mirror image card is inserted into the host, the host generates a transceiving debugging instruction to perform data transceiving debugging on the to-be-tested memory mirror image card until the transceiving debugging result meets a preset transceiving debugging condition. The test process can be set according to requirements, the limitation is small, and the test reliability is higher after the host is inserted subsequently.

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
