Embodiment
Clearer for technical matters, technical scheme and beneficial effect that the present invention is solved, below in conjunction with accompanying drawing and embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Inventor of the present invention finds, because the internal memory of non intelligent mobile phone is normally very limited, can't divide a fixing address area for data, only under the situation of the normal operation of system program, just can obtain RF calibration data accurately.The memory headroom of non intelligent mobile phone is mainly used in storage boot (bootloader), system program, and remaining a small amount of storage space user can use.And; System program can't oneself be upgraded; Thereby need the cell phone system ROMPaq be kept at memory headroom through boot and realize upgrading; But the system program of non intelligent mobile phone and RF calibration data blend into one, and when system program is upgraded, also will cover the RF calibration data, therefore can cause losing of RF calibration data.
Can at first carry out boot after under normal circumstances system boot powers on, load afterwards and the operational system program, mobile phone is restarted all programs in back and all can be resetted.As shown in Figure 1, in order to realize that non intelligent mobile phone is carried out system upgrade, the state with the cell phone system operation among the present invention is divided into four kinds of patterns: backup mode, downloading mode, recovery pattern, normal mode, and also above four kinds of patterns can be switched in order.Wherein, under backup mode, can back up the radio frequency calibration data; Under downloading mode, the cell phone system ROMPaq image file that can read in the SD card also is kept at this cell phone system ROMPaq in the mobile phone EMS memory; Under the recovery pattern, can the RF calibration data that in the SD card, back up be write in the mobile phone EMS memory again, make the RF calibration data can not lose, system program is upgraded successfully; Under normal mode, the mobile phone normal boot-strap.
Clock module in the mobile phone (RTC, Real Time Clock) is mainly used in timing in addition, and mobile phone is under off-mode usually; Time on the mobile phone still will continue to move, as long as not power down of clock module, promptly the battery in the mobile phone is not pulled up; Clock module promptly can operate as normal so; Therefore the corresponding zone bit of every kind of pattern is set, through the zone bit of clock module register record present mode, after mobile phone is restarted; System just can confirm which kind of state is system operate under according to the zone bit that writes down in the clock module register.
Below how to adopt the SD card that non intelligent mobile phone is carried out system upgrade through specific embodiment explanation, with reference to Fig. 2, the present invention provides the method for the non intelligent mobile phone of first kind of embodiment through SD card upgrade system program, this method may further comprise the steps:
Step S01 detects mobile phone power-on, gets into step S02;
Step S02, whether the particular combination key that detects this mobile phone through boot is pressed, if get into step S03; If, do not get into step S04;
Step S03 writes the zone bit of backup mode in the clock module flag register, gets into step S05;
Step S04 judges in the present clock module flag register whether be the zone bit of downloading mode through boot, if not, gets into step S05; If get into step S06;
Step S05, the operational system program gets into step S09;
Step S06 reads the cell phone system ROMPaq image file in the SD card and writes mobile phone, gets into step S07;
Step S07 writes the zone bit that recovers pattern in the clock module flag register, gets into step S08;
Step S08, start again gets into step S01;
Step S09 judges in the present clock module flag register whether be the zone bit of backup mode, if, get into step S10, if not, get into step S12;
Step S10 backs up the RF calibration data in the mobile phone and write in the SD card, gets into step S11;
Step S11 writes the zone bit of downloading mode in the clock module flag register, gets into step S08;
Step S12 judges in the present clock module flag register whether be the zone bit of recovery pattern, if, get into step S13, if not, get into step S15;
Step S13 reads the RF calibration data that are stored in the SD card and preserves entering step S14;
Step S14 writes the zone bit of normal mode in the clock module flag register, gets into step S08;
Step S15, when being the zone bit of non-recovery pattern in the said clock module flag register, the mobile phone normal boot-strap.
Can find out from above scheme, when mobile phone power-on, if said particular combination key is pressed; The zone bit of backup mode is just write in the clock module flag register, and then the operational system program is the zone bit of backup mode in the clock module flag register at this moment; Cell phone system is in backup mode so, just can back up the radio frequency calibration data, to prevent the losing of RF calibration data in the process of upgrading; Simultaneously because the state of cell phone system operation is following order: therefore backup mode, downloading mode, recovery pattern, normal mode, just can write the zone bit of downloading mode in the clock module flag register after the radio frequency calibration data is backed up; Then start again, system can get into boot again so, and said particular combination key is not pressed; Be the zone bit of downloading mode this moment in the clock module flag register; Cell phone system is in downloading mode so, just can from the SD card, read cell phone system ROMPaq image file and the cell phone system ROMPaq is kept to be about to original system program in the internal memory of mobile phone and to be updated to the cell phone system ROMPaq in the SD card, when cell phone system program image file writes in the internal memory of mobile phone fully; Just can the zone bit that recover pattern be write in the clock module flag register; Then start once more, this moment, said particular combination key was not pressed, and was the zone bit of recovery pattern in operational system program and the clock module flag register; Just can the RF calibration data of backup be written in the internal memory of mobile phone again; Make the RF calibration data can not lose, and the zone bit of normal mode is write in the clock module flag register, then start again; Be the zone bit of normal mode this moment in the clock module flag register; Therefore the mobile phone normal boot-strap is preserved RF calibration data and cell phone system ROMPaq in the internal memory of mobile phone simultaneously simultaneously, makes the system program of non intelligent mobile phone upgrade successfully.
Said process needs 4 start process altogether, but concerning the user, the SD card that only needs to store required upgrade file inserts mobile phone, presses preset particular combination key and can accomplish all escalation processs, and is easy to operation.And, almost be the SD card of mobile phone standard configuration now owing to adopt, and SD is stuck in the whole world unified standard is arranged, thereby can overcome the incompatible shortcoming of present upgrade software.Tradition is through computer serial ports upgrading cell phone system software, and speed has only 112.5KB/s usually.And the SD card reading speed of 6 grades (class6) can reach 6MB/s, even the SD card of 2 grades (class2) also can reach 2MB/s, so adopt the SD card upgrade reliable at a high speed.
In practical implementation, can further expand and optimize such scheme, for example; If clock module power down once, the information of clock module preservation also just possibly make a mistake so, for avoiding above-mentioned mistake; When said particular combination key is not pressed, can carry out following steps
Detect whether once power down of clock module, if carry out the step of said operational system program; If, do not carry out said boot and judge in the present clock module flag register whether be the step of the zone bit of downloading mode.
In practical implementation, as shown in Figure 3, the method for the non intelligent mobile phone of second kind of embodiment through SD card upgrade system program also is provided, concrete, further comprising the steps of after step S02, if the judged result of step S02 gets into step S16 for not;
Whether once step S16 detects clock module power down, if get into step S05; If, do not get into step S04.
Further, in order to ensure the mobile phone successful accuracy of upgrading smoothly, the method for the non intelligent mobile phone upgrade-system program of second kind of embodiment, further comprising the steps of, after the step S06, get into step S18.
Step S18 judges whether upgrading is successful, if not, gets into step S08, stops upgrading; If, get into step S07, make that the zone bit with normal mode writes in the clock module flag register again after confirming to upgrade successfully, so that the successful system program of upgrading can operate as normal.
In order to let the user in time understand the upgrade status of mobile phone, in escalation process, also can show upgrade status and updating result,
For example, in the present embodiment, concrete steps are following, and after step S18, if not, then upgrading is unsuccessful, gets into step S19; If get into step S20;
Step S19 shows the preface miscue, gets into step S08, and start again stops upgrading;
Owing to meeting display routine miscue on the mobile phone interface, the start again of this moment can be carried out through user's operation at this moment, also can automatic control of system carry out.
Step S20 shows the progress of upgrading and upgrades successfully entering step S07.
In practical implementation, because the restriction in non intelligent mobile phone EMS memory space possibly can't add complete cell phone system ROMPaq image file to upgrade in boot; In addition; System need to have confirmed behind first bunch of file of operation to search based on the chained list in the file allocation table required bunch address, and this action need reads SD card data continually and follows a large amount of calculating, very consuming time; For further improving upgrading efficient; As shown in Figure 4, the present invention provides reading the cell phone system ROMPaq image file in the SD card and writing the method for mobile phone of a kind of embodiment, specifically may further comprise the steps:
Step S010 reads the file allocation table of cell phone system ROMPaq image file in the SD card and is kept in the preset buffer memory;

i(i=1 under original state), and according to this bunch number A
i, obtain this bunch number A
iPairing physical address obtains the corresponding content of this bunch number Ai from file allocation table;
Step S012 is according to the said prevariety A that works as
iPairing physical address reads the pairing cell phone system ROMPaq of this physical address image file fragment and preservation;
Step S013 according to from file allocation table, obtaining the pairing content of this bunch number Ai, judges whether cell phone system ROMPaq image file finishes, if not, gets into step S014; If get into step S016;
Step S014 is according to working as prevariety A
iPairing content is obtained the following cluster A of cell phone system ROMPaq image file
I+1, get into step S015;

Step S016, program reads end.
For step S010, for fear of frequent SD is sticked into capable read operation, the space of preset buffer memory is marked segment space in user's available internal memory and is formed; And user's available internal memory itself is very limited, can't whole file allocation table be written into internal memory, therefore adopts the partial content with whole file allocation table to be kept in the preset buffer memory; Can predict through preset buffer memory which piece content is to be about to frequent access in the whole file allocation table, only this piece content is written into preset buffer memory and gets final product, and because non intelligent mobile phone is single-threaded; Escalation process only need carry out unidirectional read operation from the beginning to the end to mobile phone system upgrade program image file; So the effective rate of utilization of buffer memory can be very high, therefore, in the scheme in the present embodiment; Can think, when basis is worked as prevariety A
iFrom the file allocation table of buffer memory, obtain as prevariety A
iDuring pairing content, all can find in the file allocation table of buffer memory as prevariety A
iPairing content.Certainly work as according to working as prevariety A
iFrom the file allocation table of buffer memory, obtain as prevariety A
iPairing content, and can't find as prevariety A in the file allocation table of buffer memory
iDuring pairing content, as long as update the content of buffer memory file allocation table, so as prevariety A
iPairing content just can find.Therefore through file allocation table being kept at the scheme in the buffer memory; Can avoid continually SD being sticked into capable read operation; Simultaneously through with bunch mode all the content of mobile phone system upgrade program image file is read; Can avoid a large amount of calculating, thereby can save time, realize more efficient quick ground upgrading.
For step S011, the first bunch of number A of cell phone system ROMPaq image file
1Can be kept in the root directory of SD card cell phone system ROMPaq image file, so the first bunch number of cell phone system ROMPaq image file can directly be obtained from root directory.
