The burning flow process of the burned device of this flash memory and burned system will be described in detail below.As shown in Figure 4, can carry out burning to the flash memory of many pieces of Bluetooth chips in the burned flow process of described flash memory, described flash memory is the flash memory module being encapsulated in Bluetooth chip inside, or is hung on the flash chip of Bluetooth chip outside outward simultaneously.
Burned for flash memory device is connected with parallel port extended line by USB extended line with host computer, and by after the chip link of the burned device of burning/recording chip and flash memory is connected, system enters duty.
Step 1, system initialization step.
Whether all chip links of upper computer detection exists the Bluetooth chip of flash chip or band flash memory, detecting the burned device of flash memory connects needs after burning/recording chip, read the size treating the flash memory storage district of burning/recording chip on the one hand piecewise, on the other hand for this treats that burning/recording chip parsing or wrapper contain the image file of Bluetooth chip parameter, and whether the size detecting this flash memory storage district is greater than the size of image file, when the size in flash memory storage district is greater than the size of image file, then judge that this treats that burning/recording chip is writable; Otherwise burning/recording chip is made mistakes to point out this to treat, follow-up burning step is not performed to this chip.When all chips are all made mistakes, then exit this burning flow process; When having at least one piece of chip writable, then continue to perform this burning flow process.Therefore, should be appreciated that in following steps and only writable will be treated that burning/recording chip operates.
In the present embodiment, except comprising Bluetooth chip parameter in image file, the also memory location of reserved Bluetooth address and device name.In this memory location, predetermined Bluetooth address and device name data can be included in advance, this memory location can be identified fast when resolving image file.Before follow-up burning Bluetooth address and device name, as required, for every piece is treated that burning/recording chip produces separately new Bluetooth address and device name, then the Bluetooth address newly produced and device name can be replaced original data in image file.
Step 2, Flash memory erase step.
This step for send a disposable erasing of erase command need the flash memory storage district of burning/recording chip, to reach the object of fast erase.Idiographic flow is as follows:
Step 201, the chip selection signal that host computer puts needed burning/recording chip by the P0 ~ P7 of parallel port end be effective, treats the chip selection signal input of the chip link of burning/recording chip as put, and by USB interface removal need the full wafer of burning/recording chip and protect;
Step 202, host computer sends the instruction in all flash memory storage districts of erasing to needed burning/recording chip, receives after this instruction until burning/recording chip, starts erasing;
Step 203, host computer checks whether the flash memory storage district treating burning/recording chip wipes successfully piecewise, until need the flash memory of burning/recording chip and all wipe successfully.
As to need the flash memory storage district size of burning/recording chip identical, be all fixing because its erasing is consuming time, as long as wherein a slice has been wiped successfully, then can judge that other treats that burning/recording chip is all wiped successfully; As flash memory storage, district is not of uniform size, then wait for the success of all chip erases.
Step 204, the chip selection signal putting needed burning/recording chip is invalid, and the full wafer protection of putting its chip is effective, terminates erasing flow process.
Step 3, image file burning step.
This step is used for disposablely being burnt in needed burning/recording chip by the valid data comprised in the image file of 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, remove institute need burning/recording chip full wafer protect;
Step 302, extracts frame data by frame sign from image file;
Step 303, check whether the data extracted comprise Bluetooth address and device name, in this way, then determine that memory location that 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 step 302 afterwards; As no, then jump procedure 304.Now also determine that current burning flow process does not need burning Bluetooth address and device name, thus 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, during as being all hexadecimal FF, then think non-effective data.
As the data extracted be valid data, then enter step 305, otherwise return step 302, or extract full image file, process ends.
Step 305, the chip selection signal putting needed burning/recording chip is effective;
Step 306, host computer sends to needed burning/recording chip and writes data command, is written to by the valid data of extraction in needed burning/recording chip;
Extracted valid data are being written to after in burning/recording chip by step 307, and the chip selection signal putting needed burning/recording chip is invalid;
Step 308, detects the last frame whether present frame is image file, then performs step 309 in this way, otherwise jump procedure 302;
Step 309, the full wafer protection of putting needed burning/recording chip effectively, terminates image file burning flow process.
The present embodiment is when image file burning, and host computer sends a burning instruction can carry out image file burning to needed burning/recording chip, reduces the consuming time of burning.Further, also validity check is carried out to the data of image file in the present embodiment, improve burning efficiency.In addition, in image file for follow-up burned Bluetooth address and device name reserve can direct burned region, and identifiable design goes out this reserved region when image file burning, making in Bluetooth address and device name burning step can direct burning, need not like the prior art, need again to wipe and carry out burning again after the storage area of burning Bluetooth address and device name, thus decrease command operation number of times, reduce consuming time, raise the efficiency.
Step 4, Bluetooth address and device name burning step.
The chip that this step is used for for treating burning produces Bluetooth address and device name, and according to being the memory location that Bluetooth address and device name are reserved in the image file obtained, piecewise Bluetooth address and device name are burnt to corresponding treating in the flash memory storage district of burning/recording chip.Its idiographic flow is:
Step 401, for every sheet treats that burning/recording chip produces Bluetooth address and device name, and the Bluetooth address Bluetooth address newly produced and device name replaced in the frame data retained in image file burning step and device name, thus treat that burning/recording chip generates one and is embedded with new Bluetooth address and the frame data of device name for every a slice;
Treat that burning/recording chip produces separately Bluetooth address and device name for every a slice in this step, wherein every a slice treats that the Bluetooth address of burning/recording chip all has uniqueness.For ensureing the uniqueness of Bluetooth address, the present embodiment be adopt Bluetooth address automatically cumulative 1 method.
Generally, the present embodiment is placed on Bluetooth address and device name in adjacent address area, and its space taken is fixed as 72 bytes; We are its reserved 256 bytes, the namely page size of a FLASH (flash memory), because each write operation of FLASH is all according to a page size, namely a frame sign is write, and when burned Bluetooth address and device name, as long as revise content inside these 72 bytes, become burned FLASH after a complete Frame with adjacent front and back data encapsulation.
Step 402, remove the full wafer protection that N sheet treats burning/recording chip, N is natural number;
Step 403, puts N sheet and treats that the chip selection signal of burning/recording chip is effective;
Step 404, reads N sheet and treats to embedded in new Bluetooth address and the frame data of device name corresponding to burning/recording chip;
Step 405, host computer exports 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 effective, keep other chip selection signal treating burning/recording chip to be invalid;
Step 406, host computer sends to the burned device of chip and writes data command, the frame data that embedded in new Bluetooth address and device name is write to N sheet and treats burning/recording chip;
Step 407, host computer exports 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, keep other chip selection signal treating burning/recording chip to be invalid;
Step 408, puts N sheet and treats that the full wafer protection of burning/recording chip is effective;
Step 409, detects N+1 sheet and treats that burning/recording chip is the need of burned Bluetooth address and device name, after then putting N=N+1 in this way, jump to step 402; As complete need the Bluetooth address of burning/recording chip and the burning of device name, then terminate this Bluetooth address and device name burning flow process.
Data content due to the burned Bluetooth address of reality and device name itself in the present embodiment is fewer, be less than a page size (256bytes), and because having reserved the space of burning Bluetooth address and device name during burning image file, thus eliminate the step of again wiping, even if therefore burning piecewise herein, the consuming time of whole burning process is also less than 100 milliseconds.Simultaneously, this burning completing image file and Bluetooth address and device name in a burning flow process of the utility model, during the existing chip burned device burning Bluetooth chip inherently solved, because of the problem of communication of can not starting shooting after cause burning without Bluetooth address.The burning control procedure that also makes automatic generation Bluetooth address more becomes robotization.
Step 5, reads verification step.
This step is used for reading the burned image file treated in burning/recording chip piecewise, and verifies.
Consider the singularity of image file structure, the present embodiment reads every sheet and treats that the partial data in the flash memory storage district of burning/recording chip verifies.In a kind of most preferred embodiment, the MTU (MTU) reading to read in verification step is a SECTOR (district), read 12K data before in flash memory storage district to verify, then every sheet reading frame number is divided into 3 frames to run through, if 8 chips to be verified all will be verified, as long as also read 96K data to verify, whole process can complete for about 2 seconds.Therefore the checking of high-level efficiency pin-point accuracy is achieved.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 critical data of wherein certain part.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement etc., all should be included within protection domain of the present utility model.
