EEPROM initialization data and the FLASH data with the preservation in the FLASH master slice write each FLASH; D. during complete machine powering, the EEPROM initialization data that FLASH is preserved writes among the EEPROM.The present invention has reduced the chance of wherein makeing mistakes easily greatly in whole process of production, reduced a large amount of download equipment and artificial, has reduced production cost and has improved the efficient of producing, and has reduced direct labor's burden, has improved the quality of product.
Description
Technical field
The present invention relates to memory technology, particularly in the production run to the initialization of storage unit.
Background technology
Usually in the hardware of data processing equipment, two kinds of memory devices of FLASH equipment and EEPROM equipment are arranged usually, and FLASH equipment is used for storage and does not often become the less demanding data of storage speed, price is relatively low, and has special write device can carry out initialization to write.EEPROM equipment is used to store frequent change, and storage speed requires than higher data, and relative price is higher, does not have special write device to carry out initialization.
With the set-top box production run is example, often need in the production run to become the FLASH data creating master slice data (FLASH that stores these master slice data calls the FLASH master slice) to send to factory, the FLASH data in the FLASH master slice are write among each FLASH by the special-purpose write device of FLASH.And EEPROM is not just had corresponding initialization wiring method, often all need by factory with other download equipment with the EEPROM initialization data by the specific download software download in EEPROM.So just caused some following inconvenience for factory:
1. from efficient and qualitatively,, in large batch of production run, can make mistakes unavoidably to cause and do over again or unpack defective because every set-top box all needs manually to download the EEPROM initialization data;
2. from production cost,, in large batch of production run, need expend a large amount of download equipments owing to every set-top box all needs EEPROM initialization data down.And if press the initialization that each workman is responsible for 2 machines, and 10000 output just needs 5000 station output, and cost is very high;
3. on speed of production, if arrange 10 stations, each station is responsible for writing of 2 machines, and every machine downloads to download from link and finishes and need calculate in 1 minute, under situation about not ging wrong fully, needs finish in especially 500 minutes.
Summary of the invention
Technical matters to be solved by this invention is, provides in process of production a kind of, need not specially each EEPROM to be carried out the initial method that initialization data is downloaded.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be, to the initial method of EEPROM, may further comprise the steps in the production run:
A, the EEPROM initialization data is downloaded in the EEPROM model machine;
B, the EEPROM initialization data in the EEPROM model machine is imported the FLASH master slice;
C, the EEPROM initialization data and the FLASH data of the preservation in the FLASH master slice are write each FLASH;
When d, complete machine powering, the EEPROM initialization data that FLASH is preserved writes among the EEPROM.
In the practical operation, step a, b carry out in the laboratory, promptly the EEPROM initialization data is downloaded and all had the special messenger to be responsible for to the importing of EEPROM initialization data, and workload is little, has reduced the chance of wherein makeing mistakes easily greatly.EEPROM imports the EEPROM initialization data automatically, need not manually download, reduce a large amount of download equipments to the EEPROM initialization data of each EEPROM on the production line in process of production, has reduced production cost and production time.
Further, for the secondary that prevents FLASH imports, in the steps d, after the EEPROM initialization data that FLASH is preserved writes EEPROM, the EEPROM initialization data that deletion FLASH preserves.Concrete, complete machine writes FLASH among the EEPROM with the EEPROM initialization data of preserving by its own EEPROM read-write capability.
The invention has the beneficial effects as follows, in whole process of production, reduced the chance of wherein makeing mistakes easily greatly, reduced a large amount of download equipment and artificial, reduce production cost and improved the efficient of producing, reduced direct labor's burden, improved the quality of product.
Embodiment
1. before production software was submitted in the laboratory to, artificial earlier download EEPROM initialization data was downloaded in the EEPROM model machine, and the EEPROM model machine has only one, and download is little;
2. the EEPROM initialization data is all imported in the FLASH master slice with the FLASH write device in the laboratory again, generate jointly in conjunction with other FLASH data message and produce required software and data, the EEPROM initialization data deposits the Backup Data district in; The EEPROM initialization data comprises the check code of signing messages, enciphered message, factory's tune-up data, configuration information and these data messages;
3. this software and data being write all production in factory by the FLASH write device goes in FLASH; (producing intrinsic flow process)
4. FLASH equipment and EEPROM equipment are packed in the target product; (producing intrinsic flow process)
5. when target product powers up, automatically judge whether to need oppositely to import the EEPROM initialization data in Backup Data district by the EEPROM read-write capability of target product self, as needs, automatically the EEPROM initialization data of FLASH storage is imported to then that (this process is finished automatically by software among the EEPROM, need not manual intervention, and only need can not destroy production procedure below 1 second), after judging that again EEPROM writes successfully, remove the Backup Data district of FLASH equipment.
