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
Figure 1A 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 1A, specifically include：
S110, host computer determine whether itself is connected with pinboard.
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 pinboard in the present embodiment；Pinboard is used
In introducing or drawing signal to facilitate connecting test instrument or provide signal source, EMMC to be measured in the present embodiment passes through switching
Plate is connected with host computer, and makes corresponding operation according to the order of host computer.
Illustratively, the host computer determines whether to be connected with pinboard, can include：The host computer determines whether
The device number of the pinboard；If so, then the host computer is connect with the pinboard；Otherwise, the host computer is not connected with institute
State pinboard.
Specifically, pinboard is an external equipment, when host computer is PC, if PC is connected with pinboard, then
The device number of the identification information, i.e. pinboard of external equipment can be shown in the display screen of PC.If the display screen of PC
In do not show the identification information of external equipment, then PC is not connected with pinboard, then can not perform order.
If S120, the host computer are connected with the pinboard, the host computer is connected by usb communication to described turn
Fishplate bar sends order, so that the pinboard tests EMMC according to the order.
Wherein, USB (Universal Serial Bus, universal serial bus) communicates, i.e. USB communication protocol, 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.As shown in Figure 1B, Tu1BWei
The schematic diagram that host computer is connect with pinboard by usb communication, in the present embodiment, host computer, that is, usb host, pinboard is
USB device.When host computer is connected with pinboard, host computer can be connected to send to pinboard by usb communication and be ordered.Its
In, order can be including a variety of, such as Ctrl CMD, that is, EMMC orders, transceiving data order Data CMD, user type order
User CMD, commands in return RESP CMD and interruptive command STOP CMD etc., then, the life that pinboard is sent again according to host computer
EMMC is tested in order.If host computer does not connect pinboard, then, pinboard does not perform order.
The present embodiment is connected to send to pinboard by usb communication and be ordered, so that pinboard carries out EMMC according to order
Test, can effectively avoid the problem that EMMC performance test methods inefficiency, realize the effect for effectively improving testing efficiency.
Embodiment two
Fig. 2 is a kind of flow chart of EMMC test methods provided by Embodiment 2 of the present invention, and the present embodiment is in above-mentioned implementation
On the basis of example, connected after the pinboard sends order, further included by usb communication in the host computer：On described
Position machine determines whether the sending time of the order is more than preset delay time threshold value；If it is not, then the host computer determines institute
Order is stated to send successfully；Otherwise, the host computer determines that the order sends failure.
Correspondingly, the method for the present embodiment includes：
S210, host computer determine whether itself is connected with pinboard, if so, continuing to execute S220.
S220, the host computer are connected to send to the pinboard by usb communication and be ordered.
S230, the host computer determine whether the sending time of the order is more than preset delay time threshold value.
The delay for having certain time is ordered since host computer is sent, delay time threshold value can be set, according to hair
Whether lose one's life time of order meets the condition of delay time threshold value, to determine whether order sends success.Wherein, delay time threshold
Value can be set as a fixed quiescent value, and such as 5s can also set any one according to the situation of actual test EMMC
Variable dynamic value, such as 1s, 2s and 3s.
Specifically, determine that whether host computer sends the time of order more than preset delay time threshold value, if it is not, then performing
Step S240 and step S250；If so, perform step S260.
S240, the host computer determine that the order is sent successfully.
S250, the pinboard test EMMC according to the order.
Specifically, if pinboard is successfully received the order of host computer transmission within a certain period of time, then, host computer exists
It sends and is ordered successfully in preset delay time threshold value.
Illustratively, after the host computer determines that the order is sent successfully, can also include：The host computer foundation
The pinboard determines whether the order runs succeeded to the response message of the order.
Specifically, pinboard performs the equipment of connection the operation of the corresponding command after the order for receiving host computer, when
After the completion of execution, response message (Response information) is sent back into host computer, host computer is true according to the response message received
Order of accepting one's fate runs succeeded.In the present embodiment, if pinboard receives order, but the not content of response command, then, turn
Fishplate bar will not send response message to host computer, and host computer is not due to receiving response message, thus may determine that order performs
Failure.It should be noted that host computer determines whether to receive response message according to the response time threshold value of setting.Wherein, it rings
The set-up mode of time threshold is answered to be repeated no more as the set-up mode of delay time threshold value.Specifically, when more than response
Between after threshold value, when host computer does not receive the data information or response message of slave computer transmission also, determine that order performs failure.
S260, the host computer determine that the order sends failure.
Specifically, being ordered since host computer connects to send to the pinboard by usb communication, in the process, having can
Line fault, network delay and usb communication can be will appear the reasons such as to go wrong, lead to pinboard in preset delay time
The order of host computer transmission is not received in threshold value, therefore, host computer can determine that order sends failure.
The present embodiment determines whether the order transmission of host computer succeeds, to judge to transfer by predetermined time delay threshold value
Whether plate is tested EMMC according to order, by the processing path of optimization, saves processing time, effectively increases test
The effect of efficiency.
