Embodiment
The invention provides a kind of mass production method of storage card, mode by normal commands reads storage card, judge the type of storage card by the storage card control chip packets of information that reads, and send privately owned order by the mode of normal commands, write in the described control chip with configuration file and external code that will be corresponding with the control chip that card type memory adapts, according to configuration file that writes and external code, send the privately owned main control chip of ordering of the bad piece of scanning storage card by the mode of normal commands, main control chip can carry out bad block scan to nonvolatile memory, and the bad block message that will scan and relevant information write in the storage card, thereby finish the volume production of storage card.
One skilled in the art will appreciate that storage card generally comprises control chip and nonvolatile memory, it forms structure as shown in Figure 2.Described nonvolatile memory can be flash memory (Flash) etc.Control chip is used for controlling the read-write to nonvolatile memory.Nonvolatile memory is used for canned data, comprising hidden area and normal areas.Described hidden area be the user the zone that can not read and write, it is used to store manufacturer's information and bad block message of mentioning before that manufacturer writes and the relevant information that comprises chip specification, physical parameter, configuration information, interface type information etc.Described control chip is read and write control according to the information in the hidden area to normal areas.
In the prior art, also there is multiple card reader, is used for being connected the back storage card is carried out read-write operation with computer.No matter the storage card of which kind of brand can be applicable to the card reader adaptive with its model, and this card reader also can be the product of the arbitrary brand of arbitrary producer.Like this, because the versatility of card reader in market, and cheap, if can adopt card reader that storage card is realized volume production, will overcome the problem of versatility difference in the prior art, and reduce the cost of volume production greatly.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
Fig. 3 shows the process flow diagram of mass production method embodiment of the present invention, as shown in the figure, comprising:
Step 301: the mode by normal commands reads storage card, is judged the type of storage card by the storage card control chip packets of information that reads.
Different storing card type difference, the operation of adopting common card reader that storage card is carried out all is a normal commands.In this step, can commonly there be the mode of order that storage card is read by sending.
When the normal commands that sends and card type memory adapted, reading the result was storage card control chip packets of information, comprises the relevant information of storage card control chip in this packets of information.If the normal commands and the card type memory that send are incompatible, that then returns reads the relevant information that the result is not the storage card control chip, but the information in the address of being read.For example, when the mode by normal commands is carried out single or multiple when reading to storage card, and described repeatedly reading when not reaching in the storage card default continuous reading times, what storage card returned is to read the content of storing in the address.And the content that at every turn reads all is identical.
And the number of times that the mode by normal commands reads storage card is when meeting or exceeding the preset times that reads continuously in the storage card, what return then is the relevant information of control chip, be when not reaching preset times in the storage card with reading times to read the result different.
Therefore, if the normal commands and the storage card that send adapt, then can be by reading the type that the result obtains storage card.
For example, the normal commands of transmission is to be that read the address of 0x00000000 to storage card.As seen, this address is the first address of nonvolatile memory in the storage card.Usually, storage card is preset with reading times.When the reading times of the normal commands of sending did not reach the default number of times of storage card, it was constant reading the result, all is the content in this first address; And reading times is when reaching the storage card preset times, and reading the result is the relevant information of this storage card control chip.
Step 302: send privately owned order, this privately owned order writes configuration file and the external code corresponding with the control chip that card type memory adapts in the described control chip by the mode of normal commands.
Concrete, this step can be packaged into privately owned order the packet of a sector storage amount of capacity in the storage card, and the least unit that normal commands is operated storage card is a sector in the storage card, the feature that is to say the normal commands packet is that its size is a sector storage capacity, like this, after privately owned order being packaged into the packet of a sector storage amount of capacity in the storage card, this privately owned order just can be operated storage card as normal commands, and promptly privately owned order is operated storage card by the mode of normal commands.For example, the capacity of a sector of existing storage card is generally 512 bytes,, privately owned order can be encapsulated as the packet of 512 byte-sized here, and like this, privately owned order can be operated storage card by normal commands.
In the packet of this encapsulation, the information in the packet header indicates that this order is not the order of common reading non-volatile storage, and indicates it is special privately owned order, is the content of privately owned order in the packet inclusion.
One skilled in the art will appreciate that in the described configuration file, include the correlation parameter of drive controlling chip executable operations.And write the corresponding configuration file of control chip that adapts with card type memory, in subsequent step, during drive controlling chip executable operations, can carry out according to described configuration file.
Described external code is the order that the drive controlling chip can executable operations.According to above-mentioned configuration file, promptly according to the correlation parameter of drive controlling chip executable operations in the configuration file, described external code can be operated storage card by the drive controlling chip.Comprise in the described control chip that at random (Random Access Memory, RAM), described external code can be written among the RAM of control chip ROM (read-only memory).
Above-mentioned configuration file that writes and external code adapt with card type memory, still, are configuration file and the external codes at a series of the type.Like this, because described configuration file and external code be at the versatility of a series of card type memories, in the time of may be at specific this series main control chip type, it be very high driving the efficient that main control chip operates.Concrete, the sign (ID) of specific main control chip nonvolatile memory in the connection mode in when work and storage card is specific, correlation parameter in the configuration file and the command format in the external code are at general connection mode and general nonvolatile memory, so efficient is not very high.Therefore, operate and have higher efficient, can also comprise following step 401～402 after the step 302 in order to drive main control chip:
Step 401: main control chip returns the sign and the connection mode of nonvolatile memory according to described configuration file and external code.
In this step, concrete according to described configuration file according to parameter in the described common configuration file and general external code, return the sign and the connection mode of nonvolatile memory.
Step 402: sign and connection mode according to the nonvolatile memory that returns send privately owned order, and this privately owned order will write in the described control chip with the control chip that card type memory adapts strict corresponding configuration file and external code by the mode of normal commands.
Because preceding step has been returned the sign and the connection mode of nonvolatile memory, according to this sign and connection mode, can accurately know the particular type and the correlation parameter of nonvolatile memory, also just can know strict corresponding configuration file and external code.Therefore, in this step, will write in the described control chip with the control chip that card type memory adapts strict corresponding configuration file and external code.
The order that writes is still by sending privately owned order, and the mode by normal commands realizes.
Therefore correlation parameter in the configuration file that writes in this step and the command format in the external code all at this nonvolatile memory special use, can obtain higher efficient during fill order in subsequent step.
Step 303: according to configuration file that writes and external code, the mode by normal commands sends the privately owned main control chip of ordering of the bad piece of scanning storage card, and main control chip carry out bad block scan to nonvolatile memory.
Configuration file that in the preceding step storage card is adapted and external code are written in the main control chip, therefore, in this step, can send the privately owned main control chip of ordering of bad piece of scanning storage card, and then main control chip scans to the bad piece of storage card by the mode of normal commands.
Here, it is similar to send the mode and the front of privately owned order by normal commands.
Storage card is carried out the part that bad block scan is storage card volume production process necessity.Concrete, storage card is carried out bad block scan comprise following mode by sending privately owned order:
Mode one: storage card is carried out erase operation, judge that the DSB data store block that does not have successfully to wipe is a bad piece.
If the DSB data store block of a certain address is normal in the storage card, so, carry out the DSB data store block that erase operation can successfully be wiped this address; Otherwise when the DSB data store block of a certain address was bad piece in the storage card, erase operation can not successfully be wiped the DSB data store block of this address.Therefore, utilize this character also can judge bad piece in the storage card.
Mode two: in the address of storage card, write data, and from described address reading of data, when the data that read and the data that write not simultaneously, the DSB data store block of judging described address is a bad piece.
If the DSB data store block of a certain address is normal in the storage card, so, write data after, the data that read should be identical with the data that write.If the DSB data store block of a certain address is a bad piece in the storage card, what the data that write can not be correct is kept on this address, and when this address was read, the data that read were different with the data that write.Therefore, utilize this character can judge bad piece in the storage card.
Step 304: the bad block message that will scan writes in the storage card with relevant information.
Concrete, be the bad block message that will scan and relevant information writes hidden area in the storage card.
Described relevant information comprises chip specification, physical parameter, configuration information, interface type information etc., with class of operation of the prior art seemingly.
As seen from the above-described embodiment, this method embodiment is owing to send privately owned order, and the mode of privately owned order by normal commands read storage card, by reading the type that the result judges storage card, therefore the control chip that adapts with card type memory can be write in the storage card by corresponding configuration file, further, can finish scanning bad piece of storage card, and the bad block message that will scan and relevant information write the hidden area in the storage card, thereby finish the volume production of storage card.And utilize common card reader can implement said process, and therefore, this method highly versatile, cost is low.
This step can comprise:
The storage chip that storage card connected is scanned the back bad block table that is produced to be written in the hidden area of storage card.
Required data were written in the hidden area of storage card when the control chip that storage card connected was normally used.
If desired, comprise that also the data that the storage card safety certification is relevant are written in the safety certification data space of storage card.Described safety certification data space is positioned at storage card, promptly in the hidden area of nonvolatile memory.
Can also be included in the normal areas of storage card and write file system data or the like.
Writing mode by normal commands will the privately owned order corresponding with the control chip that card type memory adapts sends to the control chip of storage card, demand according to the volume production process, different privately owned order indication storage cards are done different feature operations, and these feature operations all are by the read-write access mode of normal commands storage card to be operated.After privately owned order sent to control chip, storage card had just entered privately owned feature operation state.And in the volume production process, storage card should remain on privately owned coomand mode.For whether the detection of stored card withdraws from privately owned state unexpectedly, in the following ways:
Operation to storage card is finished in privately owned order by the mode of normal commands after, adopt normal commands to read the address that described privately owned order is operated, if the result who returns is a control chip status information bag, and the privately owned order before comprising in this status information bag judges that then storage card is in privately owned state.This is because when storage card during in privately owned coomand mode, the content that its content that common read write command is returned is not just stored.Therefore, utilize this point, can whether be in privately owned coomand mode by the detection of stored card.
Concrete, can comprise following two kinds:
A, when described privately owned order be the operation that writes data, then this privately owned order control chip of sending to storage card by normal commands is gone forward side by side behind the line operate, if adopt normal commands to read the address that described privately owned order is operated, the result who returns is a control chip status information bag, and the privately owned order before comprising in this status information bag writes the operation of data, judges that then storage card is in privately owned state.
B, when the described privately owned order operation that is reading of data, then this privately owned order control chip of sending to storage card by normal commands is gone forward side by side behind the line operate, promptly read after the storage card control chip status information bag, if read the address that described privately owned order is operated with normal commands, the result who returns is a control chip status information bag, and the privately owned order before comprising in this status information bag writes the operation of data, judges that then storage card is in privately owned state.
Whether control chip that like this, can the detection of stored card is in privately owned state.When the control chip that detects storage card is not in privately owned state, can carries out corresponding operation, thereby make the control chip of storage card recover privately owned coomand mode.
By above method embodiment as seen, mode by normal commands reads storage card, judge the type of storage card by the storage card control chip packets of information that reads, and send privately owned order by the mode of normal commands, write in the described control chip with configuration file and external code that will be corresponding with the control chip that card type memory adapts, according to configuration file that writes and external code, send the privately owned main control chip of ordering of the bad piece of scanning storage card by the mode of normal commands, main control chip can carry out bad block scan to nonvolatile memory, and the bad block message that will scan and relevant information write in the storage card, thereby finish the volume production of storage card.Utilize common card reader can implement said process, therefore, highly versatile of the present invention, cost is low.
