Here, due to mobile terminal download software version in process of production time, the screen of mobile terminal is not lighted, and various peripherals is touch-screen, keyboard, wireless module etc. such as, is all not activated, now, electric current major part consumes on CPU, therefore, and can by changing the frequency parameter of CPU, that is: by adjusting the running frequency of CPU, the object reducing current drain is reached;
According to the power supply capacity of the USBHost of computing machine used, the number of USB interface, the frequency range needing the number of the mobile terminal carrying out software version download, the CPU of mobile terminal and speed of download simultaneously, the frequency parameter of configuration CPU, wherein, the number of the mobile terminal simultaneously carrying out software version download is needed to be less than or equal to the number of USB interface, for the frequency parameter of configuration CPU, give an example, generally, the power supply capacity of the USBHost of computing machine is 500mA, the number of USB interface is 8, when carrying out mobile terminal and producing, in order to accelerate the speed of production of mobile terminal, need 8 USB interface to use simultaneously, now, the number of the mobile terminal simultaneously carrying out software version download is needed to be 8, 500mA is evenly distributed on 8 mobile terminals, then the electric current of each mobile terminal is 62.5mA, afterwards according to 62.5mA, the frequency range of the CPU of mobile terminal, and in conjunction with speed of download, the frequency parameter of configuration CPU, wherein, chip handbook provides the frequency range of the CPU of mobile terminal, described in conjunction with speed of download, the frequency parameter of configuration CPU refers to: according to the frequency parameter of CPU, after the frequency of the CPU of adjustment mobile terminal, when carrying out multi-section mobile terminal with a computing machine and download software version simultaneously, the impact of the speed of download of every portion mobile terminal is little, that is: after the frequency of the CPU of adjustment mobile terminal, both supported that carrying out multi-section mobile terminal with a computing machine downloaded software version simultaneously, and speed of download had not been affected substantially,
The frequency parameter of described CPU comprises: the value of the value of global clock frequency division register, the value of output source clock division register, phaselocked loop mode register, the value of phaselocked loop Frequency Dividing Factor L, the value of phaselocked loop Frequency Dividing Factor M, the value of phaselocked loop Frequency Dividing Factor N;
In actual application, the frequency parameter of the CPU of described configuration can be formed a new configuration file, the content of described new configuration file is the list of register and its respective value, namely can obtain content as follows:
1. global clock frequency division register, 0x15;
2. output source clock division register, 0x5200;
3. phaselocked loop mode register, 0x2;
4. phaselocked loop Frequency Dividing Factor L, 0x32;
5. phaselocked loop Frequency Dividing Factor M, 0x0;
6. phaselocked loop Frequency Dividing Factor N, 0x6;
Wherein, phaselocked loop Frequency Dividing Factor L, phaselocked loop Frequency Dividing Factor M and phaselocked loop Frequency Dividing Factor N is also register, in actual use, first read-only memory (the ROM of chip internal solidification can be entered after mobile terminal-opening, Read-OnlyMemory) program, because this program is pre-configured before the chip of mobile terminal dispatches from the factory, therefore, any amendment can not be made, that is: can run according to the frequency parameter of the CPU configured after mobile terminal-opening, if after the configuration file that described new configuration file is pre-configured before being directly added in and dispatching from the factory, due to ROM can not identify dispatch from the factory before pre-configured configuration file or described new configuration file, there will be first according to after configuration file configuration successful pre-configured before dispatching from the factory, configure again once according to described new configuration file again, now, the frequency of CPU is the frequency of the CPU of described new configuration file, the frequency of CPU is lower than frequency during normal use, so, the normal use of mobile terminal can be affected, therefore, an idle register can be added in the middle of configuration file pre-configured before described dispatching from the factory and described new configuration file, the numbering of the register of described free time needs through carefully design, that is: ROM unloading phase, the register of described free time is an actual non-existent dummy register, the numbering of the register of described free time is taken as 0xFFFFFFFF, because 0xFFFFFFFF is a maximum address value, also be a retention, therefore, any a chip all can not have register and use this address.So when performing this register, the rreturn value of configuration result is bound to as "false", and so, described new configuration file would not be configured, thus the frequency of start to CPU during normal interface can not be affected; When downloading start, comprise in the code of the frequency of adjustment CPU distinguish described new configuration file and described dispatch from the factory before the relevant information of pre-configured configuration file, accordingly, described new configuration file can be read.
Step 102: after mobile terminal-opening, judges whether start reason is download start, after being defined as downloading start, according to the frequency of the frequency parameter adjustment CPU of the CPU of configuration, enters download flow process afterwards;
Here, before judging whether start reason is download start, the method can further include:
Perform the ROM program of the chip internal solidification of mobile terminal;
Particularly, the frequency parameter of CPU pre-configured before the chip that ROM program reads in mobile terminal from flash memory (Flash) dispatches from the factory, the frequency of CPU when normally being used according to the frequency parameter of CPU;
Describedly judge that whether start reason is download start, be specially:
According to the button used during start, judge whether start reason is download start; Or,
During mobile terminal-opening, judge whether mobile terminal is equipped with battery; Or,
