Abstract
Include firmware the embodiment of the invention discloses a kind of EMMC adjustment methods and EMMC, EMMC.The EMMC adjustment methods include：Firmware receives debug command and parameter from EMMC serial ports；Debugging routine in firmware parses the debug command and parameter, is executed according to debug command and parameter, and implementing result is exported by the serial ports.The embodiment of the present invention in the firmware in EMMC by being added to debugging routine, allow firmware that the test command received and parameter to be input in debugging routine, directly EMMC is debugged, and then analysis mistake and Wrong localization are being fast implemented when product malfunctions, debugging efficiency is improved, to effectively shorten the R＆D cycle.
Description
Technical field
The present embodiments relate to memory technology more particularly to a kind of EMMC adjustment methods and EMMC.
Background technology
EMMC (Embedded Multi Media Card) is embedded multi-media card, is that MMC associations conclude, is main
For the embedded memory standard specification of the products such as mobile phone or tablet computer.EMMC is integrated with a controller in a package,
It provides standard interface and manages flash memory so that cell phone manufacturer can be absorbed in the other parts of product development, and shorten to market
Release the time of product.
For EMMC products, need constantly to debug product to effectively shorten the R＆D cycle, when product malfunctions,
Mistake and Wrong localization can also be analyzed by debugging.
Invention content
A kind of EMMC adjustment methods of offer of the embodiment of the present invention and EMMC, to be ground by this adjustment method to effectively shorten
Send out the period, and wrong and Wrong localization is analyzed when product malfunction.
In a first aspect, an embodiment of the present invention provides a kind of EMMC adjustment methods, EMMC includes firmware, is wrapped in the firmware
Include debugging routine；
The method includes：
The firmware receives debug command and parameter from EMMC serial ports；
Debugging routine in the firmware parses the debug command and parameter, is held according to the debug command and parameter
Row, and implementing result is exported by the serial ports.
Second aspect, the embodiment of the present invention additionally provide a kind of EMMC, including firmware；
The firmware includes debugging routine, for parsing debug command and parameter from EMMC serial ports, according to described
Debug command and parameter execute, and implementing result is exported by the serial ports.
The embodiment of the present invention in the firmware in EMMC by being added to debugging routine, the survey for alloing firmware that will receive
Examination order and parameter are input in debugging routine, are directly debugged to EMMC, and then are being fast implemented when product malfunctions point
Analysis mistake and Wrong localization, improve debugging efficiency, to effectively shorten the R＆D cycle.
Description of the drawings
Fig. 1 is a kind of flow chart of EMMC adjustment methods in the embodiment of the present invention one；
Fig. 2 is the structural schematic diagram of EMMC in the embodiment of the present invention two a kind of.
Specific implementation mode
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
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
Embodiment one
Fig. 1 is a kind of flow chart of EMMC adjustment methods in the embodiment of the present invention one, and the present embodiment is applicable to pair
The debugging process of EMMC, this method can be executed by the firmware of EMMC, which may be used the mode of software and/or hardware
It realizes.
The method of the embodiment of the present invention one specifically includes：
S110, the firmware receive debug command and parameter from EMMC serial ports.
The firmware is set in EMMC, and firmware includes debugging routine.EMMC serial ports is the peripheral hardware serial ports of EMMC, can be with
The debugging result exported for the debug command and EMMC that receive tester's input.
EMMC serial ports may further be used to other signals of output except debug command.But before adjustment method operation, institute
Stating firmware program can identify whether the signal received is debug command, and then carry out subsequent operation.
The parameter includes the parameter arrived involved in debugging operations.The debugging routine is used for according to debug command and parameter
Debugging operations are realized in operation.
Debugging routine in S120, the firmware parses the debug command and parameter, according to the debug command and ginseng
Number executes, and implementing result is exported by the serial ports.
The debugging operations are simple and efficient, and load or update debugging routine need to only update firmware.And debugging process
More intuitive, technical staff sees debugging result, you can learns where out of joint, or substantially orientation problem, then passes through
Provide further debug command, you can further orientation problem.
The embodiment of the present invention in the firmware in EMMC by being added to debugging routine, the survey for alloing firmware that will receive
Examination order and parameter are input in debugging routine, are directly debugged to EMMC.And then it is being fast implemented when product malfunctions point
Analysis mistake and Wrong localization, improve debugging efficiency, to effectively shorten the R＆D cycle.
Embodiment two
Fig. 2 is the structural schematic diagram of EMMC in the embodiment of the present invention two a kind of.As shown in Fig. 2, EMMC includes firmware 210
With EMMC serial ports 220.
Wherein, EMMC includes firmware 210, and the firmware 210 includes debugging routine, and EMMC serial ports is come from for parsing
220 debug command and parameter are executed according to the debug command and parameter, and implementing result is defeated by the serial ports 220
Go out.
The embodiment of the present invention allows the firmware that will receive by being added to debugging routine in the firmware in EMMC
Test command and parameter be input in debugging routine, directly the EMMC is debugged.And then fast when product malfunctions
Speed realizes analysis mistake and Wrong localization, improves debugging efficiency, to effectively shorten the R＆D cycle.
The method that the executable any embodiment of the present invention of device provided in an embodiment of the present invention provides, has execution method phase
The function module and advantageous effect answered.
Note that above are only presently preferred embodiments of the present invention and institute's application technology principle.It will be appreciated by those skilled in the art that
The present invention is not limited to specific embodiments described here, can carry out for a person skilled in the art it is various it is apparent variation,
It readjusts and substitutes without departing from protection scope of the present invention.Therefore, although being carried out to the present invention by above example
It is described in further detail, but the present invention is not limited only to above example, without departing from the inventive concept, also
May include other more equivalent embodiments, and the scope of the present invention is determined by scope of the appended claims.
