Preferably, the storage module is further configured to write the preset memory into a plurality of preset files, and store the preset files into the EMMC; the reading module reads a plurality of preset files stored in the EMMC to obtain a plurality of read contents; the judging module compares the plurality of read contents with the random number, and if the read contents are different from the random number, the EMMC hardware is judged to be abnormal.
Specifically, during testing, a plurality of file read-write tests can be performed, a random number is generated through rand, a 1M internal memory is applied, the content in the internal memory is assigned as the generated random number, the content in the internal memory is written into a plurality of files and stored in the EMMC, namely a plurality of files with the same content and the size of 1M exist in the EMMC; reading the stored files, comparing the read content with a random number to see whether content change occurs, and if so, considering that the EMMC hardware is abnormal; if the contents are the same before and after reading and writing, the test is passed, and the EMMC hardware is normal.
In addition, when the test is carried out, not only can a large-capacity read-write test, a small file read-write test, a medium file read-write test and a multi-file read-write test be carried out independently, but also each test can be carried out, so that whether the EMMC hardware is abnormal or not can be judged more accurately. By creating a plurality of threads, each thread sequentially executes GB-level and/or KB-level and/or MB-level read-write tests, if the test is interrupted, EMMC hardware is abnormal, and after the test of each thread is finished, if the read content of one or more threads is different from the corresponding random number, EMMC hardware is abnormal.
