Abstract

The embodiment of the invention discloses an EMMC testing method and an EMMC testing device. The EMMC testing method comprises the following steps: establishing communication connection between an upper computer and a lower computer based on a USB protocol; transmitting a packet between the upper computer and the lower computer through the communication connection, wherein the packet comprises a header section and a data section; the header section comprises a command type and a command executing rule. According to the embodiment of the invention, the communication connection is established based on the USB protocol, and the upper computer and the lower computer transmit the packet through the communication connection, so that the problem that the EMMC performance testing method is low inefficiency can be effectively avoided and the effect of effectively improving the testing efficiency is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the detection technology of electronic products, in particular to an EMMC testing method and device. Background technique [0002] EMMC (Embedded Multi Media Card) is an embedded multimedia card. EMMC is an embedded memory standard specification established by the MMC Association, mainly for electronic products such as mobile phones or tablet computers. EMMC integrates a controller in the package, which provides a standard interface and manages the flash memory, allowing handset manufacturers to focus on other parts of product development and shorten the time to market. [0003] As the application of EMMC becomes more and more extensive, the demand for performance testing of EMMC becomes more and more urgent. The performance test of EMMC mainly includes: power supply test, signal test, power consumption test and stability test, etc. At present, most of the EMMC performance tests adopt the chip test ...
