Method embodiment one
Referring to fig. 1, a flowchart illustrating a first step of a data processing method according to a first embodiment of the present application is shown, where an apparatus applied by the method may specifically include: the storage medium and the clock may specifically include: a memory; the method may specifically comprise the steps of:
Optionally, at least one step included in the method shown in fig. 1 may be executed by executing the first code in the memory. The first code may correspond to a first program, such as an SPL (second phase program loader) program. The second phase of SPL corresponds to the execution of a solidified boot program in the bloom (System on Chip) and then the SPL program, relative to the execution of the bloom (System on Chip).
The traditional SPL program is used for initializing the DDR, loading a secondary boot program to the initialized DDR, and then running the secondary boot program in the initialized DDR, so as to implement functions of hardware initialization, memory allocation, kernel loading and the like necessary for starting the operating system through the secondary boot program.
The embodiment of the application can improve the SPL program, and the functions of the improved SPL program can include: initializing first hardware corresponding to equipment after the equipment is powered on; and loading a kernel of the operating system into the initialized memory and loading running data corresponding to the kernel into the initialized memory under the condition that the starting mode parameters of the equipment meet the starting conditions.
In practical applications, the first program may be stored in an external Memory of the device, such as an external ROM (Read-Only Memory). In practical application, the BROM may load the first program from an external memory to an internal memory to trigger the running of the first code corresponding to the first program.
The memory of the embodiment of the application may include: a RAM (random access memory).
According to one embodiment, the first code may be loaded in an SRAM (static random-Access Memory). The SRAM can store the data stored in the SRAM without a refreshing circuit, so that the SRAM has the advantage of high speed, and the starting speed of an operating system can be increased.
According to another embodiment, the first code may be loaded in a DDR (Double Data Rate Synchronous Dynamic Random Access Memory). DDR needs to be refreshed and charged once every a period of time, otherwise, internal data disappear, and therefore DDR has high performance and is suitable for being used as a main memory of equipment. But DDR rates are lower than SRAM.
The above apparatus may include: circuitry, power up may refer to powering circuitry in the device. Wherein, the hardware in the device can have corresponding circuits. Optionally, circuitry in the device may be powered by a battery to enable powering up of the device. Optionally, it can be understood that, in the embodiment of the present application, a power-on process of a device is not limited.
In step 101, initializing the first hardware may include: a clock and a memory. Wherein the clock may provide an operating clock for other hardware of the device. Memory may be used for temporary storage of programs, data, and intermediate results.
In an optional embodiment of the present application, the initializing, in step 101, a memory corresponding to the device may specifically include: and initializing the DDR corresponding to the equipment. Of course, the embodiments of the present application are directed to
The specific memory initialized in step 101 is not limited.
In step 102, the startup mode parameters may be used to characterize the startup mode of the device. In general, different startup mode parameters may correspond to different startup modes.
The start mode parameters may include: and normal starting mode parameters, wherein the normal starting mode parameters correspond to a normal starting mode. The normal start mode may be for normal use of the device by the user, for example, enabling the user to use functions provided by an application program in the device, and the functions may include: office function, audio-visual function, instant messaging function, online shopping function, web browsing function, etc.
The start mode parameters may include: and the card swiping mode parameter corresponds to a card swiping mode. Alternatively, the start mode parameters may include: the line brush mode parameters correspond to the line brush mode.
The card swiping mode and the line swiping mode can be used for information replacement of equipment such as a mobile phone.
The differences between the card-swipe mode and the line-swipe mode may include:
the process of the card swipe mode may include: and (5) a file replacement process. The card-swipe mode may not refresh the entire partition, but replace only a portion of the file. Therefore, the content in the whole card swiping package is actually a plurality of files and directories, the content in the files and the directories is the original files which are replaced when the content is existed on the original equipment, and if the content is not existed, the content is added, so that the card swiping package is characterized in that a compressed package with the extension name of zip is usually placed on an external storage card, and the files can be replaced through a bootstrap program such as RECOVERY.
While the brush mode may replace the entire contents of the partition. Therefore, the files in the line brush package are usually one img file (partition image file).
The card swiping mode and the line swiping mode have respective characteristics and application scenes. If partial files need to be updated, the card swiping mode is the quickest naturally, because the files only need to be replaced and incremental files need to be taken, and the files which can be used by the operating system originally do not need to be taken; the card swipe approach is typically used in updates or upgrades, so that the amount of information that needs to be downloaded is minimal. In case of abnormal system, the line brush mode may be adopted, and this can replace the whole partition and avoid inconsistency.
In practical applications, the frequency of use by the user for different start-up modes may be different. Specifically, the user has the highest frequency of use for the normal start mode and has a lower frequency of use for the card-swipe mode or the line-swipe mode. More often the normal boot mode is used, less often the card swipe mode is used in case of an upgrade required, and less often the line swipe mode is used in case of operating system problems.
The data of the operating system can be utilized by different starting modes, for example, after entering the different starting modes, the interface data provided for the user can also be different.
Therefore, the embodiment of the present application creatively provides that, when the boot mode parameter of the device meets the boot condition, the second-level boot program is skipped, and the device directly enters the environment of the operating system, and specifically, the kernel of the operating system may be loaded into the initialized memory, and the running data corresponding to the kernel may be loaded into the initialized memory. The time spent by the first-level bootstrap program for loading the second-level bootstrap program and the second-level bootstrap program for hardware initialization, memory allocation and other operations can be saved, so the running time of the bootstrap program can be saved, and the starting speed of the operating system can be further improved.
The boot conditions may be used to constrain boot mode parameters that require, or are highly correlated with, the operating system. Alternatively, the boot condition may refer to a condition suitable for booting the operating system. For example, the start-up conditions may include: the startup mode parameter corresponds to a normal startup mode.
In the embodiment of the present application, the start mode of the device may include, but is not limited to: a Normal Boot (Normal Boot) mode, a card swipe (recovery) mode, or a line swipe (Fast Boot) mode, etc.
In the embodiment of the application, under the condition that the starting mode parameters correspond to the normal starting mode, the secondary boot program can be skipped, the environment of the operating system can be directly entered, and the equipment can enter the normal starting mode.
In an embodiment of the present application, the start mode parameter may specifically include: the stored startup mode parameters prior to the last power down of the device. For example, if the user-triggered command is a shutdown command or a restart command before the device was last powered off, the startup mode parameter may be a normal startup parameter. For another example, before the device is powered off last time, the instruction triggered by the user is an instruction for restoring factory settings or an instruction of the first shortcut key, and the start mode parameter may be a card swiping mode parameter. For another example, before the device is powered off last time, the instruction triggered by the user is an instruction of the second shortcut key, and the start mode parameter may be a line brush mode parameter.
In another embodiment of the present application, the start mode parameters may specifically include: a start-up mode parameter received from the peripheral device after the device is powered on.
After the device is powered on, the user may input the startup mode parameters through the peripheral. The peripheral device, which is an external device for short, refers to a hardware device connected to a computer host. Depending on the function, the peripheral device may generally comprise: input devices, display devices, printing devices, external memories, and network devices. In one example, the peripheral device may include: mouse, keyboard, earphone, display, printer, serial port, network card, etc. For example, a user may enter startup mode parameters via a keyboard and/or mouse.
In an optional embodiment of the present application, the step 102 of loading the kernel of the operating system into the memory may specifically include: and loading the kernel image of the operating system into the initialized memory.
In practical applications, the format of the kernel image may be an image compressed file. The format of the image compression file may include: the zmmage format, or the uImage format.
zImage is an Image compression file of the kernel, and is about 4M, but is less than 2M.
uinmage is processed from zmage, and uboot has a tool that can process zmage to generate uinmage. The kernel may generate zmmage and the mkimage tool in uboot may process zmmage to generate uinmage to launch uboot. This process may be: the header information of the uinimage of 64 bytes is added to the front of the zmmage.
It is understood that the format of zmmage or the format of umimage is only an example of the format of the kernel image, and it is understood that the specific format of the kernel image is not limited in the embodiments of the present application.
The operating data may refer to data required for the start-up of the operating system. The operation data may specifically include: file system, atags, or dtb.
Wherein, the ATAGs is used for transmitting information such as command lines, and specifically, the ATAGs packs parameters into an ATAG _ TAG mark to transmit information; dtb is used to convey hardware information.
In an optional embodiment of the present application, step 102 may determine a boot address of the kernel image, and transmit the kernel image and the running data to the boot address, thereby implementing booting of the operating system.
In an optional embodiment of the present application, the method may further include: transmitting pre-stored environment variable parameters to a kernel of the operating system; the pre-stored environment variable parameter may be an environment variable parameter stored before the device is powered off last time.
The environment variable parameters may be used to characterize the parameter variables that are often used. The environment variable parameters may provide a degree of configurability to the user, such as baud rate, startup parameters, and the like. Configurability means that the environment variable parameter can be added, deleted and modified, that is, the content of the environment variable parameter may change frequently, and in order not to cause damage to the code and data of the boot program due to such a change, a block dedicated to storing the environment variable parameter may be optionally reserved in the memory.
In practical applications, the environment variable parameters may be saved via a memory. The memory corresponding to the environment variable parameter may include: the memory or the external memory, or the memory corresponding to the environment variable parameter may include: static memory or dynamic memory. Alternatively, the environment variable parameters may be solidified in a non-volatile storage medium.
In an application example of the present application, the environment variable parameter may specifically include:
bootdelay, seconds waiting to perform an auto start
baudrate, baudrate of serial console
netmask, mask for Ethernet interface
ethaddr, network card physical address of ethernet card
bootfile, default download file
bootargs, boot parameters passed to kernel
bootcmd, a command executed on automatic start-up
server ip, ip (Internet Protocol) address of server end
Ipadr, local ip address
stdin, standard input device
stdout, standard output equipment
stderr, standard error equipment
In an optional embodiment of the present application, the method may further include: and after the operating system is started and before the operating system is powered off, saving the environment variable parameters of the equipment. In this way, the environment variable parameters before the last power outage can be saved.
For example, after the operating system is normally started, if the user triggers an instruction to enter the card swiping mode before the power is off, the instruction to enter the card swiping mode can be entered by updating the environment variable parameters.
To sum up, in the data processing method according to the embodiment of the present application, after the device is powered on, the first hardware corresponding to the device may be initialized, and then the kernel of the operating system is loaded into the initialized memory and the running data corresponding to the kernel is loaded into the initialized memory when the start mode parameter of the device meets the start condition. Compared with the prior art that the primary bootstrap program completes initialization of the DDR, loads the secondary bootstrap program to the DDR, and runs the secondary bootstrap program in the DDR, so that functions of hardware initialization, memory allocation, kernel loading and the like are realized through the secondary bootstrap program, the loading of the kernel can be directly performed after the initialization after the power-on is completed in the embodiment of the application, and the time spent by the loading of the secondary bootstrap program by the primary bootstrap program and the hardware initialization, the memory allocation and the like performed by the secondary bootstrap program can be saved, so that the running time of the bootstrap program can be saved, and the starting speed of an operating system can be further improved.

Currently, the environment variable parameters may be saved prior to the last power down of the device. And after the initialization of the second hardware is completed, the environment variable parameters can be relocated to determine the latest environment variable parameters.

And entering a card swiping mode, and upgrading the system. Such as OTA (Over-the-Air Technology) upgrades. OTA upgrade is a standard software upgrade mode provided by an android system. The system has powerful functions, can be upgraded without loss, mainly automatically downloads OTA upgrade packages and upgrades automatically through networks [ such as WIFI and 3G ], but also supports the upgrade from downloading the OTA upgrade packages to the SD card. The OTA upgrade package is small, typically a few M to a dozen M, so the upgrade speed is fast and, most importantly, the OTA upgrade may not backup data.
According to another embodiment, the start mode parameter may be a brush mode parameter, and the target start mode may be a brush mode. When the system enters the line brush mode, the system can be burned. The line-swiping mode is generally an upgrading mode adopted by an official, and is mainly used for swiping firmware, if the conditions that the machine cannot be started and the like are caused by equipment failure, the line-swiping mode can be considered, and the card-swiping mode is generally used for upgrading.
