Description
Technical field
The present invention relates to a kind of method of flash memory of more new cell-phone, more particularly, relate to the method that a kind of use one mobile phone directly upgrades the flash memory of another mobile phone.
Background technology
The development rapidly of radio communication has in recent years made mobile phone become indispensable information products.And mobile communication has slowly entered the epoch of the third generation (3G), and the radio communication of the high frequency range of its institute's standard means that mobile phone will no longer just can transmit the means of communication of the matter of the timbre in a low voice sound of low frequency range.The function that high frequency range is derived, except making mobile computer, PDA(Personal Digital Assistant) and notebook use mobile phone to carry out the action of wireless connections internet, even mobile phone itself is also because the prosperity of peripheral technology, development as the high color liquid crystal screen of resolving of small size, low power consuming high performance system chip (system on chip, SOC) promotion, flourish with the non-volatile flash memory of big capacity, the mobile phone that makes begins to have near personal digital assistant, even the function of personal computer.
Therefore, the function of the mobile phone of releasing the at present requirement that exceeded its normal receiving and transmitting signal of simple energy the earliest already.Relatively, what it was emphasized is the function of various sound and light programs, comprises that can show a high color liquid crystal screen of resolving picture, many lively recreation, the extra program that connects communication function such as internet browsing webpage and play various form films, audio.Therefore, this certainly will more need a huge storage area to store needed program code of these functions and data except one of needs are taken into account the embedded central microprocessor of high-effect and low power consuming.
But, thing followed problem is, stored software, program, data more than in the mobile phone, do not have fully under the bug (bugs) at the mobile phone that can't guarantee to have gone on the market, and new function in order back-up system to provide the dealer to increase, or designer's desire on this mobile phone adds new function, and these all are bound to upgrade firmware (firmware) version that is stored in the mobile phone.Also therefore, mobile phone manufacturer, mobile phone distributors or want the user to send back to desire the mobile phone of firmware updating version before the mobile phone shipment, must correspondingly carry out the program code and the data that store in the flash memory are done some change; Or user's mobile phone hinders and stored content in must its flash memory of reprogram for some reason.All above-mentioned actions all are bound to make the flash memory of this mobile phone the action of renewal.
Existing method is that the slot (slot) that utilizes personal computer to pass through the RS-232 transmission line to link a mobile phone carries out data to the flash memory of this mobile phone and transmits and upgrade.Please refer to Fig. 1, Fig. 1 is the schematic diagram of flash memories 16 in the existing personal computer 10 renewal mobile phones 12, and the RS232 transmit port 11 of personal computer 10 is the earpiece holes 13 that are connected to mobile phone 12 via a RS232 transmission line.Because the running voltage of transmit port 11 is 7～9 volts, and the voltage of earpiece holes 13 is 3.7 volts, no matter therefore transmission signals is to reach personal computer 10 from mobile phone 12, or reach mobile phone 12 from personal computer 10, all must carry out corresponding boosting via a transforming circuit 14 earlier, or the action of step-down, reach the other end again.
Before transferring data to mobile phone 12, the operating system that personal computer 10 inside must install function software and function software earlier and are suitable for, and the binary file (bin file) of the flash memory 16 of mobile phone 12 is sent in tendency to develop.And the operator must start and enter the operating system of personal computer 10 earlier, carries out this function software.Because the voltage of transmit port 11 and earpiece holes 13 is different, and the execution speed on both sides also differs, therefore before the synchronous transmission of carrying out two ends, not only to handle through transformation, also must carry out synchronization according to the communication protocol at two ends earlier, just can upgrade the action of flash memory in the mobile phone 12.
After synchronous transmission configured, next the function software of personal computer 10 wanted earlier the receiving terminal program code to be passed in the random asccess memory (RAM) 19 of mobile phone 12, just can enter the stage of transmission flash memory binary file.And when transmission flash memory binary file, personal computer 10 can carry out transfer of data work with (b) step according to following (a):
(a) personal computer 10 can stop the action that transmission proceeds to transfer to mobile phone 12 from the flash memory binary file that before was stored in personal computer 10 in this action; Certainly, if this step (a) first time is performed for this action, then can begin to transmit from the beginning of the flash memory binary file that is stored in personal computer 10.And the data that personal computer 10 is transmitted can be stored in earlier in the mobile phone 12 in the random asccess memory 19 in the buffer 15, can directly not deposit the flash memory 16 of mobile phone 12 in.This stage finishes after the buffer 15 of mobile phone 12 is filled, and continues step (b).
(b) in the middle of the flash memory 16 that this moment, mobile phone 12 can write mobile phone 12 corresponding to the interior address of the flash memory 16 of mobile phone 12 and form according to binary file institute with the fragment binary file of buffer 15.After this step finishes, if the flash memory binary file of personal computer 10 end of transmission is then finished this transmission action; Still there are data to wait to transmit if be stored in the flash memory binary file of personal computer 10, then repeating step (a).
Because employed RS-232 transmission line has the restriction of high bit rate (baud rate) 115200bit/s of standard, this is representing the speed that is equivalent to only have 14.4KByte/s each second, with the flash memory of present mobile phone 12 capacity more than the 3MByte easily, Chuan Shu time only, just need more than 200 seconds at least, and the overall time also must comprise and deposits this binary file in the flash memory 16 required time.
In addition, in the existing method, because the transmit port of personal computer 10, though have two usually as serial port, two port is still shared same frequency range, just 115200bit/s.If on behalf of operating personnel, this want once to finish the action of upgrading two mobile phones 12 with existing method, he can't obtain the efficient of twice.If the action of desiring simultaneously to upgrade several mobile phones with several personal computers 10 then its cost is quite high.In addition, because the action of this renewal is necessary for personal computer 10 and comes master control, this is representing when upgrading a plurality of mobile phone 12, and personal computer 10 will more raise the cost with respect to the highly energy-consuming of mobile phone 12.When also transmitting action owing to the use serial port simultaneously, personal computer 10 resource consumptions are quite huge, 10 runnings that are difficult to carry out other program of personal computer.Therefore, if mobile phone 12 quantity of upgrading more than, with the action that existing method is upgraded, inefficient and expensive is expected.
