Below in conjunction with Fig. 1, Fig. 2, Fig. 3 and Fig. 4, describe concrete burned control flow and the method for the burned device of flash memory providing in preferred embodiment of the present invention, burned system and burned method in detail.
A kind of burned device of flash memory, burned system and burned method of can dragging eight Bluetooth chip is provided in the present embodiment.
The burned device of flash memory is connected with parallel port extended line by USB extended line with host computer, and by after burning/recording chip is connected with the chip link of the burned device of flash memory, system enters duty.
Step 1, system initialization step.
On all chip links of upper computer detection, whether there is flash chip or with the Bluetooth chip of flash memory, detect on the burned device of flash memory and connect and need after burning/recording chip, read piecewise on the one hand the size in the flash memory storage district that treats burning/recording chip, for this, treat burning/recording chip parsing or wrapper on the other hand and contain the image file of Bluetooth chip parameter, and whether the size that detects this flash memory storage district is greater than the size of image file, when the size in flash memory storage district is greater than image file big or small, judge that this treats that burning/recording chip is writable; Otherwise point out this to treat that burning/recording chip makes mistakes, this chip is not carried out to follow-up burning step.When all chips are all made mistakes, exit this burning flow process; When having at least one piece of chip writable, continue to carry out this burning flow process.Therefore, should be appreciated that in following steps and will only the writable burning/recording chip for the treatment of be operated.
In the present embodiment, in image file, except comprising Bluetooth chip parameter, also reserve the memory location of Bluetooth address and device name.In this memory location, can include in advance predetermined Bluetooth address and device name data, to can identify fast this memory location when resolving image file.Before follow-up burning Bluetooth address and device name, can be as required, treat that burning/recording chip produces separately new Bluetooth address and device name for every piece, then the Bluetooth address newly producing and device name are replaced to original data in image file.
Step 2, flash memory erase step.
This step, for sending the disposable flash memory storage district of wiping needed burning/recording chip of erase command one time, reaches the object of wiping fast.Idiographic flow is as follows:
Step 201, the P0～P7 end of host computer by parallel port put the chip selection signal of needed burning/recording chip for effectively, treats the chip selection signal input of the chip link of burning/recording chip as put, and protects by the full wafer that USB interface is removed needed burning/recording chip;
Step 202, host computer sends the instruction of wiping all flash memory storage district to needed burning/recording chip, after burning/recording chip receives this instruction, start to wipe;
Step 203, host computer checks whether the flash memory storage district that treats burning/recording chip wipes successfully piecewise, until the flash memory of the burning/recording chip that needs is all wiped successfully.
As identical in the flash memory storage district size of needing burning/recording chip, because of it, wipe and consuming timely all fix, as long as wherein a slice has been wiped successfully, can judge that other treats that burning/recording chip all wipes successfully; As flash memory storage, district is not of uniform size, waits for all chip erase successes.
Step 204, the chip selection signal of putting needed burning/recording chip is invalid, puts the full wafer protection of its chip for effectively, finishes to wipe flow process.
Step 3, image file burning step.
This step is burnt in needed burning/recording chip for the disposable valid data by the image file that comprises Bluetooth chip parameter, and to obtain in image file be Bluetooth address and the reserved memory location of device name.Its idiographic flow is as follows:
Step 301, the full wafer protection of removing the burning/recording chip that needs;
Step 302 is extracted frame data by frame sign from image file;
Step 303, check whether the data of extracting comprise Bluetooth address and device name, in this way, the memory location that definite this current frame data should write flash memory storage district is the memory location of Bluetooth address and device name, and retain this frame data, return to afterwards step 302; As no, jump procedure 304.Now also determine that current burning flow process does not need burning Bluetooth address and device name, thereby follow-uply will not perform step 4.
Step 304, checks whether current frame data is valid data;
In the present embodiment, when whole frame data are all predetermined number, when being all hexadecimal FF, think non-effective data.
If the data of being extracted are valid data, enter step 305, otherwise return to step 302, or extracted whole image files, process ends.
Step 305, puts the chip selection signal of needed burning/recording chip for effective;
Step 306, host computer sends and writes data command to needed burning/recording chip, and the valid data of extraction are written in needed burning/recording chip;
Step 307, in extracted valid data are written to burning/recording chip after, the chip selection signal of putting needed burning/recording chip is invalid;
Step 308, whether be the last frame of image file, perform step 309 in this way if detecting present frame, otherwise jump procedure 302;
Step 309, puts the full wafer protection of needed burning/recording chip effectively, finishes image file burning flow process.
The present embodiment is when image file burning, and host computer sends a burning instruction can carry out the burning of image file to needed burning/recording chip, reduced the consuming time of burning.Further, in the present embodiment, also the data of image file are carried out to validity check, improved burning efficiency.In addition, in image file for follow-up burned Bluetooth address and device name reserve can direct burned region, and can identify this reserved region when image file burning, making in Bluetooth address and device name burning step can direct burning, needn't like the prior art, need to again wipe and after the storage area of burning Bluetooth address and device name, carry out again burning, thereby reduce command operation number of times, reduce consuming timely, raise the efficiency.
Step 4, Bluetooth address and device name burning step.
This step is used to the chip for the treatment of burning to produce Bluetooth address and device name, and according to being Bluetooth address and the reserved memory location of device name in the image file obtaining, piecewise Bluetooth address and device name are burnt in the corresponding flash memory storage district that treats burning/recording chip.Its idiographic flow is:
Step 401, treat that burning/recording chip produces Bluetooth address and device name for every, and the Bluetooth address newly producing and device name are replaced to Bluetooth address and the device name in the frame data that retain in image file burning step, thereby treat an embedding of burning/recording chip generation for every a slice, there are new Bluetooth address and the frame data of device name;
In this step, for every a slice, treat that burning/recording chip produces separately Bluetooth address and device name, wherein every a slice treats that the Bluetooth address of burning/recording chip all has uniqueness.For guaranteeing the uniqueness of Bluetooth address, the present embodiment is to adopt Bluetooth address cumulative 1 method automatically.
Generally, the present embodiment is placed on Bluetooth address and device name in adjacent address area, and its space taking is fixed as 72 bytes; We are its reserved 256 bytes, the page size of a FLASH (flash memory) namely, because the each write operation of FLASH is all according to a page size, a frame sign is write, and when burned Bluetooth address and device name, as long as revise this 72 bytes the inside contents, become burned FLASH after a complete Frame with adjacent front and back data encapsulation.
Step 402, removes the full wafer protection that N sheet is treated burning/recording chip, and N is natural number;
Step 403, puts N sheet and treats that the chip selection signal of burning/recording chip is effectively;
Step 404, reads N sheet and treats corresponding new Bluetooth address and the frame data of device name of having embedded of burning/recording chip;
Step 405, host computer is exported chip selection signal to the burned device of chip by parallel port, puts N sheet and treats that the chip selection signal of burning/recording chip is that effectively it is invalid keeping other chip selection signal for the treatment of burning/recording chip;
Step 406, host computer sends and writes data command to the burned device of chip, the frame data that embedded new Bluetooth address and device name is write to N sheet and treat burning/recording chip;
Step 407, host computer is exported chip selection signal to the burned device of chip by parallel port, puts N sheet and treats that the chip selection signal of burning/recording chip is invalid, and it is invalid keeping other chip selection signal for the treatment of burning/recording chip;
Step 408, puts N sheet and treats that the full wafer protection of burning/recording chip is effectively;
Step 409, detects N+1 sheet and treats whether burning/recording chip needs burned Bluetooth address and device name, puts after N=N+1 in this way, jumps to step 402; As completed the Bluetooth address of needing burning/recording chip and the burning of device name, finish this Bluetooth address and device name burning flow process.
In the present embodiment because the data content of the burned Bluetooth address of reality and device name itself is fewer, be less than a page size (256bytes), and during because of burning image file, reserved the space of burning Bluetooth address and device name, thereby saved the step of again wiping, even therefore burning piecewise herein, the consuming time of whole burning process is also less than 100 milliseconds.Meanwhile, this burning that completes image file and Bluetooth address and device name in a burning flow process of the present invention, from solve in essence the burned device burning of existing chip Bluetooth chip time, because of the problem of the communication that causes without Bluetooth address can not starting shooting after burning.Automatically produce Bluetooth address and also make the robotization that more becomes of burning control procedure.
Step 5, reads verification step.
This step is used for reading piecewise the burned image file for the treatment of burning/recording chip, and verifies.
Consider the singularity of image file structure, the present embodiment reads every partial data in the flash memory storage district that treats burning/recording chip and carries out verification.In a kind of most preferred embodiment, the MTU that reads to read in verification step (MTU) is a SECTOR (district), before reading in flash memory storage district, 12K data are carried out verification, every is read frame number and is divided into 3 frames and can runs through, if 8 chips to be verified all will be verified, as long as also read 96K data, verify, whole process can complete for approximately 2 seconds.Therefore realized the checking of high-level efficiency pin-point accuracy.Certainly, those skilled in the art also can adjust this partial data according to actual needs, as read front 4 frame data, or read the wherein critical data of certain part.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement etc., within all should being included in protection scope of the present invention.
