Embodiment 1

[0020] figure 1 A schematic flow diagram of an eMMC read-write test method provided in Embodiment 1 of the present invention. This embodiment is applicable to the eMMC read-write test situation. The method can be performed by an eMMC read-write test device, and specifically includes the following steps:

[0021] Step 110, write data packets to eMMC in units of data packets according to the write task, wherein the first position of the data packet records the main identifier of the current write task, and the last position of the data packet records the backup identifier of the current write task , the primary ID is consistent with the backup ID.

[0022] A data packet is a data unit in communication transmission. In this embodiment, the data packet includes: the data information to be written, the main identification and the backup identification of the current writing task, wherein the main identification is located at the first position of the data package, and the backup T...

Embodiment 2

[0033] figure 2 It is a structural block diagram of an eMMC reading and writing test device in Embodiment 2 of the present invention. Such as figure 2 As shown, the device includes:

[0034] The data writing module 210 is used to write data packets to the eMMC in units of data packets according to the writing task, wherein the first position of the data packet records the main identifier of the current writing task, and the last position of the data packet records the current writing task. Enter the backup identification of the task, the main identification is consistent with the backup identification; the identification judgment module 220 is used to read the main identification and the backup identification from the data packet of the eMMC and compare the consistency to judge the correctness of the write operation of the data packet.

[0035] This embodiment provides a kind of eMMC reading and writing test device, and the data writing module 210 writes the data packet th...

Abstract

The invention discloses an eMMC read-write test method and device. The method comprises the following steps of: writing a data packet to an eMMC according to a write-in task by taking the data packets as a unit, wherein a main identifier of the current write-in task is recorded at a first position of the data packet, a backup identifier of the current write-in task is recorded at a final position of the data packet, and the main identifier is consistent with the backup identifier; and reading the main identifier and the backup identifier out from the data packet of the eMMC, and comparing the consistency between the main identifier and the backup identifier so as to judge the write-in operation correctness of the data packet. According to the method and device disclosed by the invention, the read-write test problem of the eMMC is solved and the correctness of judging the eMMC read-write test is improved.

Description

technical field [0001] The embodiment of the present invention relates to a memory testing technology, in particular to an eMMC reading and writing testing method and device. Background technique [0002] Embedded Multi Media Card (eMMC) is an embedded memory standard specification established by the MMC Association and mainly aimed at products such as mobile phones or tablet computers. It includes at least one NAND and a controller, and the controller is configured with software. It can control the running process of eMMC. eMMC can be installed in various electronic devices and used as memory. In order to understand the operating performance of eMMC and eliminate possible faults, it is necessary to test different types of eMMC in different environments. [0003] As a memory, eMMC can perform read and write operations normally is the most important performance of eMMC, so the read and write test is also a routine test of eMMC. During the testing process, data writing oper...
