System-level test method for flash memory

A system-level test method for a flash memory, applied to a flash memory, wherein a test device is used, and the test device comprises a partition mirror storage system and a file storage system;

• an original mirror is pre-stored in the partition storage system;
• verification files having a plurality of pre-set characters pre-stored in the file storage system;
• the method comprises:
• step S1, providing a test flag file, and storing a test number parameter in the test flag file;
• step S2, determining whether a value of the test number parameter reaches a pre-set value;
• if not, turning to step S3;
• if yes, ending and counting a verification result;
• step S3, performing one partition mirror data check on all partitions of the flash memory, and performing one file data check on a current system file of the flash memory;
• and
• step S4, restarting the test device, subtracting one from the value of the test number parameter, and returning to step S2;
• wherein in step S3, the partition mirror data check comprises:
• comparing current mirrors of all of the partitions in the flash memory to the original mirror;
• in step S3, the file data check comprises:
• comparing a current system file of the flash memory to the verification file.
