6. The eMMC consistency testing method of claim 5, wherein the recording test results for each eMMC and analyzing consistency of the test results includes:
recording test results of each eMMC;
screening out the test result with the largest recorded times from the test results, and determining the test result with the largest recorded times as a target test result;
screening out test results inconsistent with the target test result from the test results, and determining the test results inconsistent with the target test result as test results inconsistent with the target test result.
7. The eMMC consistency testing method according to claim 4, wherein the recording the execution capability of each eMMC of the same batch under the driving capability of different preset gears of the preset scan software includes:
recording the execution capacity of each eMMC of the same batch under the driving capacity of the first to N-th gears of the SDR52, the DDR52, the HS200 and the HS400 respectively, wherein N is a positive integer, and the execution capacity is the qualification rate of the eMMC of the same batch conforming to the consistency in the driving test;
and arranging the execution capacity from good to bad, and determining the optimal execution capacity of the eMMC of the same batch according to the first execution capacity.
8. The eMMC consistency testing method of claim 7, wherein the determining an optimal driving capability according to the execution capability includes:
identifying scanning software and driving capability corresponding to the optimal execution capability;
and determining the identified scanning software and the driving capability corresponding to the optimal execution capability as the optimal driving capability.
9. A controller, comprising: memory, a processor and a computer program stored on the memory and executable on the processor, the processor executing the method for testing eMMC consistency according to any of claims 1 to 8 when the computer program is executed.
