Description of the drawings
Fig. 1 is a kind of flow chart of EMMC test methods in the embodiment of the present invention one；
Fig. 2 is a kind of structure chart of EMMC test devices in the embodiment of the present invention two.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limitation of the invention.It also should be noted that in order to just
Part related to the present invention rather than entire infrastructure are illustrated only in description, attached drawing.
Embodiment one
Fig. 1 is the flow chart of a kind of EMMC test methods that the embodiment of the present invention one provides, and the present embodiment is applicable to respectively
The situation of kind EMMC tests, this method can be performed by EMMC test devices provided in an embodiment of the present invention, which can adopt
It is realized with the mode of software and/or hardware, which can be integrated in any equipment for providing EMMC test functions, such as typical
Be subscriber terminal equipment, can be computer etc., as shown in Figure 1, specifically including：
S110, host computer and slave computer are established by usb protocol and communicated to connect.
Wherein, host computer is the computer that can directly send out manipulation command, usually PC (personal computer,
Personal computer), host computer (host), master computer (master computer) and upper computer (on
Position machine) etc., various signal intensities are shown on screen, host computer is sends commands to slave computer in the present embodiment；Slave computer is
The computer that equipment obtains status of equipment is directly controlled, (Programmable Logic Controller, can compile usually PLC
Journey logic controller), SCM (single chip microcomputer, microcontroller), slave computer (subordinate calculate
Machine) and lower computer (slave computer) etc., slave computer is makes accordingly according to the order of host computer in the present embodiment
Operation, including pinboard and EMMC to be measured；USB (Universal Serial Bus, universal serial bus) agreement is a kind of
It supports to carry out the communication protocol of serial data transmission between usb host and USB device, can include a variety of, such as can be
USB-HID agreements, i.e. HID (Human Interface Device, human interface device) agreement.Specifically, host computer is under
Position machine has collectively constituted EMMC test development platforms, since host computer is to obtain absolute ownership, in USB interface
Certain specific command form linked up just is must comply in communication protocol, between host computer and slave computer, to reach communication
Purpose.
S120, the host computer transmit the first message by described communicate to connect to the slave computer.
Wherein, message contains the complete data information that will be sent to exchange the data cell with transmission in network.
In the present embodiment, message is the command information for completing EMMC test process, for the structure of 64 bytes, title such as S_USB_
PACKET.Wherein, structure is a kind of data structure.In the present embodiment, message is classified according to executive agent, including the first report
Text and the second message, wherein, the first message is host computer by communicating to connect the command information transmitted to slave computer.
Illustratively, first message includes EMMC orders, transceiving data order, user type order and interruptive command
At least one of.
Wherein, Ctrl CMD are EMMC orders, include CMD0 to CMD60 totally 61 subcommands, and each subcommand
Have the function of different.For example, the function of Ctrl CMD18 for continuous slave device read block to host computer, until being interrupted
The data number of blocks of request is interrupted or is had reached in order；The function of Ctrl CMD31 rises for write protection data information
Beginning address.
Transceiving data order Data CMD are ordered comprising Data Read (digital independent) and Data Write (data write-in)
Two subcommands are enabled, as the initial order for sending and receiving data, for reading data and write-in data.User type order
User CMD, for the specific command that user needs, such as open command, shutdown command, delay command and reset command.Interrupt life
STOP CMD are enabled, for stopping the operation being carrying out.
For example, Ctrl CMD 18 are the reading order in EMMC orders.When host computer reads data information, sending
After complete reading order CMD 18, need to send Data Read orders, such slave computer just starts the data information in EMMC
It reads and is sent to host computer.It should be noted that slave computer is not immediately by number after reading order CMD18 has been performed
It is believed that breath is sent to host computer, but sent after Data Read orders are received.Therefore, EMMC orders do not need to distinguish life
Whether order carries data, is conducive to improve testing efficiency.
S130, the slave computer transmit the second message by described communicate to connect to the host computer.
Illustratively, second message includes commands in return.
In the present embodiment, the command information that the second message is transmitted for slave computer by communication connection to host computer, such as
Commands in return RESP CMD.Wherein, commands in return RESP CMD are reply (Response information) of the slave computer to host computer.Under
Position machine performs the equipment of connection the operation of the corresponding command after the order for receiving host computer, will after the completion of execution
Response information sends back host computer, and host computer confirms that order runs succeeded according to the response message received.
It should be noted that in the present embodiment, do not limit step S120 and S130 performs sequence.
An embodiment of the present invention provides a kind of methods of EMMC tests, are established and communicated to connect by usb protocol so that is upper
Machine carries out message transmissions with the slave computer by the communication connection, can effectively avoid EMMC performance test methods single
Problem can realize the effect of a variety of EMMC performance tests.
