Embodiment
In order to make technical matters solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The present inventor finds, because the internal memory of non intelligent mobile phone is normally very limited, cannot be the fixing address area of Data Placement one, only when system program normally runs, just can obtain RF calibration data accurately.The memory headroom of non intelligent mobile phone is mainly used in storing boot (bootloader), system program, and remaining a small amount of storage space user can use.And, system program cannot oneself be upgraded, need by boot cell phone system ROMPaq be kept at memory headroom thus realize upgrading, but system program and the RF calibration data of non intelligent mobile phone blend into one, while system program is upgraded, also will cover RF calibration data, therefore can cause the loss of RF calibration data.
First system boot can perform boot after powering under normal circumstances, and load afterwards and operational system program, mobile phone is restarted rear all programs and all can be resetted.As shown in Figure 1, in order to realize carrying out system upgrade to non intelligent mobile phone, in the present invention, the state demarcation that cell phone system runs is become four kinds of patterns: backup mode, downloading mode, reforestation practices, normal mode, and above four kinds of patterns can switch in turn.Wherein, under backup mode, can back up by radio frequency calibration data; Under downloading mode, the cell phone system ROMPaq image file in SD card can be read and this cell phone system ROMPaq is kept in mobile phone EMS memory; In recovery mode, can re-write in mobile phone EMS memory by the RF calibration data of backup in SD card, RF calibration data can not be lost, and system program upgrades successfully; In the normal mode, mobile phone normal boot-strap.
Clock module (RTC in addition in mobile phone, Real Time Clock) be mainly used in timing, usual mobile phone in the power-offstate, time on mobile phone still will continue operation, as long as clock module not power down, namely the battery in mobile phone is not unplugged, so namely clock module can normally work, therefore the zone bit that often kind of pattern is corresponding is set, by the zone bit of clock module register record present mode, after mobile phone is restarted, system just can according to the zone bit recorded in clock module register, under which kind of state certainty annuity operates in.
Illustrate how to adopt SD card to carry out system upgrade to non intelligent mobile phone below by way of specific embodiment, with reference to Fig. 2, the invention provides the method for non intelligent mobile phone by SD card upgrade system program of the first embodiment, the method comprises the following steps:
Step S01, detects mobile phone power-on, enters step S02;
Step S02, whether the particular combination key being detected this mobile phone by boot is pressed, and if so, enters step S03; If not, step S04 is entered;
Step S03, by the zone bit write clock module identification register of backup mode, enters step S05;
Step S04, to be judged in present clock module identification register to be whether the zone bit of downloading mode, if not, enters step S05 by boot; If so, step S06 is entered;
Step S05, operational system program, enters step S09;
Step S06, reads the cell phone system ROMPaq image file in SD card and writes mobile phone, entering step S07;
Step S07, by the zone bit write clock module identification register of reforestation practices, enters step S08;
Step S08, starts shooting again, enters step S01;
Step S09, to judge in present clock module identification register being the whether zone bit of backup mode, if so, enters step S10, if not, enter step S12;
Step S10, is undertaken backing up by the RF calibration data in mobile phone and writes in SD card, entering step S11;
Step S11, by the zone bit write clock module identification register of downloading mode, enters step S08;
Step S12, to judge in present clock module identification register being the whether zone bit of reforestation practices, if so, enters step S13, if not, enter step S15;
Step S13, the RF calibration data that reading is stored in SD card is also preserved, and enters step S14;
Step S14, by the zone bit write clock module identification register of normal mode, enters step S08;
Step S15, when being the zone bit of non-recovery pattern in described clock module flag register, mobile phone normal boot-strap.
As can be seen from above scheme, when mobile phone power-on, if described particular combination key is pressed, just by the zone bit write clock module identification register of backup mode, then operational system program, it is now the zone bit of backup mode in clock module flag register, so cell phone system is in backup mode, just can back up by radio frequency calibration data, to prevent the loss of RF calibration data in the process of upgrading, the state simultaneously run due to cell phone system is following order: backup mode, downloading mode, reforestation practices, normal mode, therefore, just can by the zone bit write clock module identification register of downloading mode after radio frequency calibration data backs up, then again start shooting, so system can reenter boot, described particular combination key is not pressed, it is now the zone bit of downloading mode in clock module flag register, so cell phone system is in downloading mode, just can read cell phone system ROMPaq image file from SD card and cell phone system ROMPaq is kept in the internal memory of mobile phone the cell phone system ROMPaq be updated to by original system program in SD card, when cell phone system program image file writes in the internal memory of mobile phone completely, just can by the zone bit write clock module identification register of reforestation practices, then again start shooting, now described particular combination key is not pressed, operational system program and be the zone bit of reforestation practices in clock module flag register, just can the RF calibration data of backup be re-write in the internal memory of mobile phone, RF calibration data can not be lost, and by the zone bit write clock module identification register of normal mode, then again start shooting, it is now the zone bit of normal mode in clock module flag register, therefore mobile phone normal boot-strap, preserve RF calibration data and cell phone system ROMPaq in the internal memory of simultaneously mobile phone simultaneously, the system program of non intelligent mobile phone is upgraded successfully.
Said process needs 4 start process altogether, but concerning user, only needs the SD card that will store required upgrade file to insert mobile phone, press default particular combination key and can complete all escalation processs, easy to operation.Further, be almost the SD card of mobile phone standard configuration now owing to adopting, and SD is stuck in the whole world and has unified standard, thus the incompatible shortcoming of current upgrade software can be overcome.Tradition is by computer serial port upgrading cell phone system software, and speed only has 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, therefore adopt SD card upgrade reliable at a high speed.
In concrete enforcement, can further expand such scheme and optimize, such as, if clock module once power down, the information that so clock module is preserved also just may make a mistake, for avoiding above-mentioned mistake, when described particular combination key is not pressed, following steps can be performed
Detect clock module whether once power down, if so, perform the step of described operational system program; If not, perform described boot and to judge in present clock module identification register being the whether step of the zone bit of downloading mode.
In concrete enforcement, as shown in Figure 3, also provide the method for non intelligent mobile phone by SD card upgrade system program of the second embodiment, concrete, after step S02, further comprising the steps of, if the judged result of step S02 is no, enter step S16;
Whether once step S16, detect clock module power down, if so, enter step S05; If not, step S04 is entered.
Further, accuracy can be upgraded successfully smoothly in order to ensure mobile phone, the method for the non intelligent mobile phone upgrade-system program of the second embodiment, further comprising the steps of, after step S06, enter step S18.
Step S18, judges that whether upgrading is successful, if not, enters step S08, stop upgrading; If so, enter step S07, make after confirmation upgrades successfully, then by the zone bit write clock module identification register of normal mode, so that the system program upgraded successfully can normally work.
In order to the upgrade status that user can be allowed to understand mobile phone in time, also can show upgrade status and updating result in escalation process,
Such as, in the present embodiment, concrete steps are as follows, after step S18, if not, then upgrade unsuccessful, enter step S19; If so, step S20 is entered;
Step S19, the miscue of display sequence, enters step S08, again starts shooting, stop upgrading;
Now due to meeting display routine miscue on mobile phone interface, start again now can be undertaken by user operation, also can system automatically control to carry out.
Step S20, shows the progress of upgrading and upgrades successfully, entering step S07.
In concrete enforcement, due to the restriction in non intelligent mobile phone EMS memory space, possibly cannot add complete cell phone system ROMPaq image file to upgrade in boot, in addition, system needs the address of searching required bunch based on the chained list in file allocation table after determining first bunch of file of needs operation, this action need reads SD card data and adjoint a large amount of calculating continually, very consuming time, for improving upgrading efficiency further, as shown in Figure 4, the invention provides the cell phone system ROMPaq image file in a kind of reading SD card of embodiment and write the method for mobile phone, specifically comprise the following steps:
Step S010, reads the file allocation table of cell phone system ROMPaq image file in SD card and is kept in default buffer memory;
Step S011, obtains the current cluster A of cell phone system ROMPaq image file
i(in an initial condition i=1), and according to this bunch number A
i, obtain this bunch number A
icorresponding physical address, obtains the content that this bunch number Ai is corresponding from file allocation table;
Step S012, according to described current cluster A
icorresponding physical address, reads the cell phone system ROMPaq image file fragment corresponding to this physical address and preserves;
Step S013, according to the content obtained from file allocation table corresponding to this bunch number Ai, judges whether cell phone system ROMPaq image file terminates, and if not, enters step S014; If so, step S016 is entered;
Step S014, according to current cluster A
ithe lower cluster A of corresponding content obtaining cell phone system ROMPaq image file
i+1, enter step S015;
Step S015, variable i, from adding one, enters step S011,
Step S016, program reads and terminates.
For step S010, in order to avoid carrying out read operation to SD card frequently, the space of preset buffer memory from user can internal memory mark segment space and formed, and user can internal memory itself very limited, whole file allocation table cannot be loaded into internal memory, therefore adopt and the partial content of whole file allocation table is kept in default buffer memory, can predict which block content is about to frequently access in whole file allocation table by the buffer memory preset, only this block content is loaded into the buffer memory preset, and due to non intelligent mobile phone be single-threaded, escalation process only needs to 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 scheme in the present embodiment, can think, when according to current cluster A
icurrent cluster A is obtained from the file allocation table of buffer memory
iduring corresponding content, in the file allocation table of buffer memory, all current cluster A can be found
icorresponding content.Certainly work as according to current cluster A
icurrent cluster A is obtained from the file allocation table of buffer memory
icorresponding content, and cannot current cluster A be found in the file allocation table of buffer memory
iduring corresponding content, as long as update the content of buffer memory file allocation table, so current cluster A
icorresponding content just can find.Therefore by file allocation table being preserved scheme in the buffer, can avoid carrying out read operation to SD card continually, simultaneously by with bunch mode all the content of mobile phone system upgrade program image file is read, a large amount of calculating can be avoided, thus can save time, realize more upgrading efficient quick.
