Description

Method and device for supporting multiple mobile terminals to download software version by one computer

The invention relates to a version software downloading technology, in particular to a method and a device for supporting a plurality of mobile terminals to download software versions by one computer. Background technique

With the rapid development of mobile phone technology, people's functional requirements for mobile phone terminals are getting higher and higher, especially smart phone terminals with powerful multimedia functions are highly sought after. In order to occupy the market, various mobile phone manufacturers have launched smart phones of various price points in a timely manner for different groups of people. Moreover, Gartner Consulting's market research analysis: In the next 10 years, the smart phone market will maintain a high-speed and stable growth. Therefore, each mobile phone manufacturer is committed to the development and production of smart phones. However, for mobile phone manufacturers, one of the major issues now is how to improve production efficiency to meet the expanding needs of consumers.

The production process of a smartphone can be divided into two parts, one is the general structural assembly, and the other is the download of the version software; wherein the structure assembly takes a long time, but the download of the version software also takes a lot of time. Generally, mobile phones need to be upgraded once in production, from the production to the delivery. In the current popular Windows Mobile platform and Android platform, a version of the software contains files ranging from 130MB to 160MB. It takes about 5 minutes to download the version software via Universal Serial Bus (USB). However, if a computer downloads only one mobile phone, the output is far from satisfactory, so one computer The need to download software for multiple mobile phones at a time is on the horizon.

The number of phones supported by a computer depends on two conditions:

First, the number of USB interfaces on the computer; Second, the power supply capability of the computer USB host device (Host).

Among them, in general, there will be at least 8 USB interfaces on one computer, so the first condition can be satisfied. However, the standard USB Host has a power supply capacity of only 500 mA, while the current Qualcomm platform downloads currents of around 100 mA to 120 mA, that is, when 4 to 5 mobile phones are simultaneously downloaded, sudden current consumption. It may exceed 500mA, which causes two serious problems: First, excessive current causes the computer to blue screen or restart; Second, excessive current causes the USB transmission to fail, ie: The software version download is unsuccessful.

In summary, the above two problems will cause the stagnation of mobile phone production, which will affect the interests of mobile phone manufacturers. Summary of the invention

In view of the above, the main object of the present invention is to provide a method and a device for supporting a plurality of mobile terminals to download a software version, so as to solve the current when a computer simultaneously downloads software versions of multiple mobile terminals.

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

A method for supporting a plurality of mobile terminals to download a software version by a computer of the present invention, as shown in FIG. 1, includes the following steps:

Step 101: Configure a frequency parameter of the CPU, and then perform step 102;

Here, since the mobile terminal downloads the software version during the production process, the screen of the mobile terminal It does not light up. Various peripheral devices such as touch screen, keyboard, wireless module, etc. are not activated. At this time, most of the current is consumed on the CPU. Therefore, the frequency parameter of the CPU can be changed, that is, by adjusting the operation of the CPU. Frequency, to achieve the purpose of reducing current consumption;

Configuring the frequency parameter of the CPU according to the power supply capability of the USB Host of the computer, the number of USB interfaces, the number of mobile terminals that need to simultaneously download the software version, and the downloading speed of the CPU of the mobile terminal; The number of mobile terminals for downloading the software version is less than or equal to the number of USB interfaces; for configuring the frequency parameters of the CPU, for example, generally, the USB Host of the computer has a power supply capacity of 500 mA, and the number of USB interfaces is 8, in progress. When the mobile terminal is produced, in order to speed up the production speed of the mobile terminal, eight USB interfaces need to be used at the same time. At this time, the number of mobile terminals that need to download the software version at the same time is 8 , and 500 mA is evenly distributed to 8 mobile terminals. Then, the current of each mobile terminal is 62.5 mA, and then the frequency parameter of the CPU is configured according to the frequency range of the CPU of the mobile terminal of 62.5 mA and the download speed; wherein, the frequency range of the CPU of the mobile terminal is provided in the chip manual ; the combined download speed, configure the frequency of the CPU The number refers to: According to the frequency parameter of the CPU, after adjusting the frequency of the CPU of the mobile terminal, when downloading the software version of multiple mobile terminals simultaneously by one computer, the download speed of each mobile terminal has little effect, namely: After adjusting the frequency of the CPU of the mobile terminal, it is supported to simultaneously download a software version of a plurality of mobile terminals by using one computer, and has basically no influence on the download speed;

The frequency parameters of the CPU include: a value of a global clock frequency division register, a value of an output source clock frequency division register, a value of a phase locked loop mode register, a value of a phase locked loop frequency division factor L, and a phase locked loop frequency division factor M. Value, the value of the phase-locked loop division factor N;

In the actual application process, the frequency parameter of the configured CPU may be formed into a new configuration file, and the content of the new configuration file is a list of registers and their corresponding values, that is, the following content may be obtained:

1. Global clock divider register, 0x15; 2. Output source clock divider register, 0x5200;

3. Phase-locked loop mode register, 0x2;

4. Phase-locked loop division factor L, 0x32;

5. Phase-locked loop division factor M, 0x0;

6. Phase-locked loop division factor N, 0x6;

The phase-locked loop frequency division factor phase-locked loop frequency division factor M and the phase-locked loop frequency division factor N are also registers. In actual use, the mobile terminal first enters the chip-cured read-only memory (ROM) , Read-Only Memory program, because this program is pre-configured before the chip of the mobile terminal is shipped, therefore, no modification can be made, ie: the mobile terminal will run according to the configured frequency parameter of the CPU after booting, if The new configuration file is directly added to the configuration file that has been pre-configured before leaving the factory. Since the ROM cannot recognize the configuration file that has been pre-configured before leaving the factory or the new configuration file, it will appear pre-configured according to the factory. After the configuration of the good configuration file is successful, it is configured again according to the new configuration file. At this time, the frequency of the CPU is the frequency of the CPU of the new configuration file, and the frequency of the CPU is lower than the frequency of normal use. , which will affect the normal use of the mobile terminal. Therefore, the configuration file and the new one that have been pre-configured before the factory can be A free register is added in the middle of the configuration file, and the number of the free register needs to be carefully designed, that is, in the ROM startup phase, the free register is an empty register that does not actually exist, and the number of the free register is taken. For OxFFFFFFFF, since OxFFFFFFFF is a maximum address value, it is also a reserved value. Therefore, it is impossible for any chip to have a register to use this address. Therefore, when the register is executed, the return value of the configuration result will be "false". Thus, the new configuration file will not be configured, so that the frequency of the CPU when booting to the normal interface will not be affected; At the time of power-on, the code for adjusting the frequency of the CPU includes information for distinguishing the new configuration file from the configuration file that has been pre-configured at the factory, whereby the new configuration file can be read. Step 102: After the mobile terminal is powered on, determine whether the booting reason is downloading and booting, determining that after downloading and starting, adjusting the frequency of the CPU according to the configured frequency parameter of the CPU, and then entering the downloading process;

Here, the method may further include: before determining whether the booting cause is downloading and booting, the method further includes:

Executing a ROM program that is internally solidified by the chip of the mobile terminal;

Specifically, the ROM program reads, from the flash memory (Flash), the frequency parameter of the CPU that has been pre-configured before the chip of the mobile terminal is shipped, and obtains the frequency of the CPU when the chip is used normally according to the frequency parameter of the CPU;

The determining whether the booting reason is a downloading booting is specifically:

According to the button used at the time of power-on, it is determined whether the booting reason is downloading and booting; or, when the mobile terminal is powered on, determining whether the mobile terminal is equipped with a battery; or

After the mobile terminal is powered on, can it find the set identification bit;

Among them, when the mobile terminal is in normal use, only the power button is used to turn on the power, and in the production process, when directly entering the download and booting, different button modes can be set, for example: setting the volume up button and the volume down button simultaneously Then press the power button again to directly enter the download and boot;

In the actual application process, if the mobile terminal directly enters the download and start, after connecting with the USB interface of the computer, the power supply capability of the USB interface enables the mobile terminal to directly enter the download and start, and at this time, the mobile terminal is not equipped with the battery, and When the mobile terminal is in normal use, it needs to be powered by the battery. Therefore, whether the mobile terminal is installed or not can be determined whether the mobile terminal is powered on or not.

In the production process of the mobile terminal, an identifier bit may be set in advance in the memory of the mobile terminal. After the mobile terminal is powered on, it will search for the identifier bit. If it can be found, it means that the download is started, if not found, The description is normal use boot; after the download is completed, delete the flag, so as not to affect the normal use of the mobile terminal; The adjusting the frequency of the CPU according to the frequency parameter of the configured CPU, specifically:

Reading the frequency parameter of the configured CPU from the memory, and performing a read or write operation on the register corresponding to the frequency parameter according to the configured frequency parameter of the CPU; wherein, the register corresponding to the frequency parameter is read The operation of writing or writing refers to reading the contents of the register or writing the content in the register; determining whether to read or write the register according to the attribute of the register, and the attributes of the register have been specified in the prior art.

In practical applications, the code for adjusting the frequency of the CPU can be placed in the internal buffer (IMEM) to ensure that the CPU of the mobile terminal is double-rate synchronous dynamic random access (DDR SDRAM, Double Data Rate Synchronous Dynamic Random Access). Memory ) Not available, ie: Cannot affect the execution of the code;

Make sure that no action is taken when the download is not powered on.

The present invention will be further described in detail below with reference to the embodiments.

The application scenario of this embodiment is as follows: The chip used by the mobile terminal is a Qualcomm platform 7x25, or 7x27. In normal use, the CPU frequency is 400 MHz.

In this embodiment, the current needs to be adjusted to between 60 and 80 mA, so that one computer simultaneously supports multiple mobile terminals to download the software version, and the download speed has little effect. Therefore, the content of the new configuration file is specifically:

1. Global clock divider register, 0x15;

2. Output source clock divider register, 0x5200;

3. Phase-locked loop mode register, 0x2;

4. Phase-locked loop division factor L, 0x32;

5. Phase-locked loop division factor M, 0x0;

6. Phase-locked loop division factor N, 0x6;

The new configuration file needs to conform to the definition of Qualcomm, save the new configuration file to the memory of the mobile terminal, and the pre-configured configuration file and the new configuration at the factory. Add an idle register in the middle of the file, and the number of the free register is taken as

OxFFFFFFFF, Qualcomm can not use any register in any chip produced in the past, present or future. When this register is executed, the return value of the configuration result will be "false", so it will not Affects the frequency of the CPU when booting to the normal interface; After using the frequency parameter of the CPU configured above, the frequency of the CPU can be reduced to

80MHz, the specific calculation process is as follows:

The frequency calculation formula for the CPU in the Qualcomm Platform Manual is:

CPU frequency = clock source I (global division ratio * output source division ratio) (1) The clock source is derived from the phase-locked loop according to this example:

Clock source = phase-locked loop frequency = TCXO * (L + M/N) ( 2 ) where TCXO is an external fixed crystal with a value of 19.2MHz and the set L, M and N values are substituted into the formula (2) ), then, the phase-locked loop frequency is 19.2*50 = 960MHz. According to the Qualcomm platform manual, the sixth bit of the global divider register determines whether the CPU frequency comes from global src or axi_marm_src, where global_src and axi_marm_src are the two clock sources inside the chip, with different The division ratio is the subclock of the phase-locked loop. The internal module of the chip can select which clock source the working clock comes from through the register, ie: from global src or axi-marm-src, for example, The clock of the AXI (Advanced Extensible Interface) is configured to come from axi marm src, and the operating frequency of the CPU can be selected from global src or axi-marm_src through the memory, in this embodiment, The sixth bit of 0x15 is 0, so it comes from axi_marm_src. The 0th to the 1st bits of the global divider register determine the division ratio of axi_marm_src, which is 0x1 in this embodiment. Check the Qualcomm platform manual to see that the division ratio is 2. The output source divider register bits 3 to 6 determine the output source division ratio. In this embodiment, it is a binary 101, which is a decimal 5. Check the Qualcomm platform manual to know that the division ratio is 6, and the global score will be obtained. The ratio of the frequency ratio and the output source division ratio is brought into the formula (1), which leads to: CPU frequency = 960 / (2 * 6) = 80Mhz

In addition, you can connect the running CPU to the Trace instrument, you can directly see that the CPU frequency is reduced.

After the mobile terminal is powered on, the ROM program of the internal firmware of the mobile terminal is first executed, and then it is determined whether the booting reason is downloading and booting, and after determining that the downloading is started, the code for adjusting the frequency of the CPU is placed in the IMEM to adjust the frequency of the CPU. The code reads the frequency parameter of the CPU in the new configuration file from the memory, and performs adjustment of the CPU frequency; specifically, reads the frequency parameter of the configured CPU from the memory, and reads the register in the frequency parameter or Write operation; Here, in this embodiment, according to the button used at the time of power-on, it is determined whether the booting reason is downloading and booting, specifically, setting the button used for downloading and booting is to simultaneously press the volume up key and the volume down key, and then Press the power button, when it is judged that the button used for power-on is to press the volume up button and the volume down button at the same time, and then press the power button, it means that the mobile terminal is powered on for downloading.

After adjusting the frequency of the CPU, enter the download process.
