Method embodiment one
Referring to fig. 1, a flowchart illustrating steps of a first embodiment of a data processing method of the present application, a device to which the method is applied may specifically include: a storage medium and a clock, the storage medium may specifically include: a memory; the method specifically comprises the following steps:
Alternatively, at least one step included in the method shown in fig. 1 may be performed by running a first code in a memory. The first code may correspond to a first program, such as a SPL (second stage program loader, secondary Program Loader) program. The second stage corresponding to SPL is relative to the BROM (a piece of boot program already cured inside the Chip) in the SOC (System on Chip), which starts the boot program that was first cured in the BROM and then the SPL program.
The traditional SPL program is used for finishing the initialization of the DDR, loading the secondary bootstrap program to the initialized DDR, and then running the secondary bootstrap program in the initialized DDR so as to realize the functions of hardware initialization, memory allocation, kernel loading and the like necessary for starting the operating system through the secondary bootstrap program.
The embodiment of the application can improve the SPL program, and the functions of the improved SPL program can comprise: after the equipment is powered on, initializing first hardware corresponding to the equipment; and loading the kernel of the operating system into the initialized memory and loading the operation data corresponding to the kernel into the initialized memory under the condition that the starting mode parameter of the equipment meets the starting condition.
In practical applications, the first program may be stored in a Memory external to the device, such as an external ROM (Read-Only Memory). In practical applications, the BROM may load the first program from the external memory to the internal memory, so as to trigger the operation of the first code corresponding to the first program.
The memory of the embodiment of the application may include: 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 refresh circuit, so that the SRAM has the advantage of high speed, and the starting speed of an operating system can be improved.
According to another embodiment, the first code may be loaded at a DDR (double Rate synchronous dynamic random Access memory, double Data Rate Synchronous Dynamic Random Access Memory). The DDR is refreshed and charged once at intervals, otherwise, the internal data disappear, so the DDR has higher performance and is suitable for being used as a main memory of equipment. But DDR is slower than SRAM.
The device may include: powering up may refer to powering up circuitry in a device. Wherein the hardware in the device may each have corresponding circuitry. Alternatively, the circuitry in the device may be powered by a battery to enable powering up of the device. Alternatively, it may be appreciated that embodiments of the present application do not impose limitations on the power-up process of the device.
In step 101, the initializing the first hardware may include: clock and 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, step 101 may specifically include: initializing 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, a start-up mode parameter may be used to characterize a start-up mode of a device. In general, different start-up mode parameters may correspond to different start-up modes.
The start-up mode parameters may include: and the normal starting mode parameter corresponds to the normal starting mode. The normal start-up mode may allow a user to use the device normally, for example, to use functions provided by applications in the device, which may include: office functions, audio-visual functions, instant messaging functions, online shopping functions, web browsing functions, and the like.
The start-up mode parameters may include: the card swiping mode parameter corresponds to the card swiping mode. Alternatively, the start-up mode parameters may include: and the wire brush mode parameter corresponds to the wire brush mode.
Both the card swiping mode and the line swiping mode can be used for information replacement of devices such as mobile phones.
The distinction between card swiping mode and line swiping mode may include:
the process of the card swiping mode may include: file replacement process. The card swiping mode may not re-flush the entire partition, but replace only a portion of the file. The content in the whole card swiping package is actually files and directories, the original files are replaced by the content in the original equipment, and if the content is not, the content is added, so the card swiping package is characterized in that a compressed package with the extension of zip is usually placed on an external memory card, and the files can be replaced by a bootstrap program such as RECOVERY.
And the line brush mode may replace the entire contents of the partition. The files inside the line brush package are therefore typically img files (partition image files) one by one.
The card swiping mode and the line swiping mode have respective characteristics and application scenes. If part of the files need to be updated, the card swiping mode is naturally the fastest, because the card swiping mode only needs to carry the replacement files and the increment files, and the files which can be used by the operating system originally are not carried; card swiping is often used in updates or upgrades so that the amount of information that needs to be downloaded is minimal. Under the abnormal condition of the system, a line brush mode can be adopted, and the whole partition can be replaced by the line brush mode, so that the problem of inconsistency can be avoided.
In practical applications, the frequency of use of the different start modes by the user may be different. Specifically, the user uses the normal start mode most frequently, and uses the card swipe mode or the line swipe mode less frequently. The more cases are the normal start-up mode, while the less cases are the card swipe mode in case of upgrades being needed, and the less cases are the line swipe mode in case of operating system problems.
The normal start mode, the card swipe mode and the line swipe mode, while different start modes of the three start modes can utilize data of the operating system, the data of the operating system utilized by the three start modes can be different, for example, interface data provided to a user after entering the different start modes can also be different.
Therefore, the embodiments of the present application creatively propose that, in the case that the startup mode parameter of the device meets the startup condition, the secondary boot program is skipped, and the device directly enters the environment of the operating system, specifically, the kernel of the operating system may be loaded into the initialized memory, and the operation data corresponding to the kernel may be loaded into the initialized memory. Because the time spent by the first-level bootstrap program for loading the second-level bootstrap program and the second-level bootstrap program for carrying out hardware initialization, memory allocation and other operations can be saved, the running time of the bootstrap program can be saved, and the starting speed of an operating system can be further improved.
The boot conditions may be used to constrain the boot mode parameters that require the operating system, or that have a high correlation with the operating system. Alternatively, the startup condition may refer to a condition suitable for starting up the operating system. For example, the start-up conditions may include: the start-up mode parameter corresponds to a normal start-up mode.
In the embodiment of the present application, the startup mode of the device may include, but is not limited to: normal Boot mode, card swipe mode, or line swipe mode, etc.
In this embodiment of the present application, when the startup mode parameter corresponds to the normal startup mode, the secondary boot program may be skipped, and the device may be caused to enter the normal startup mode by directly entering the environment of the operating system.
In an embodiment of the present application, the start mode parameter may specifically include: a start-up mode parameter stored before the last power-off of the device. For example, the user-triggered instruction is a shutdown instruction, or a restart instruction, before the device was last powered down, and 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 a factory setting restoration instruction, or an instruction of the first shortcut key, and the start mode parameter may be a card swipe 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 parameter may specifically include: a start-up mode parameter received from the peripheral after the device is powered up.
After the device is powered on, the user may enter the start-up mode parameters through the peripheral. The peripheral is an abbreviation of external equipment, and refers to hardware equipment connected outside the computer host. Depending on the function, the peripheral may generally comprise: five general classes are input devices, display devices, printing devices, external memory, and network devices. In one example, a peripheral may include: mouse, keyboard, earphone, display, printer, serial port, network card, etc. For example, the user may enter the start-up mode parameters via a keyboard and/or mouse.
In an alternative embodiment of the present application, step 102 loads the kernel of the operating system into the memory, which may specifically include: and loading the kernel mirror image of the operating system into the initialized memory.
In practical applications, the kernel image may be in the form of an image compressed file. The format of the mirrored compressed file may include: zImage format, or uiimage format.
Where zImage is an Image compressed file of the kernel, image is about 4M, and zImage is less than 2M.
The uImage is processed from zImage, and one tool is available in uboot, so that zImage can be processed to generate uImage. The kernel may generate zImage, and the mkimage tool in uboot may process zImage to generate uImage to launch uboot. The processing process can be as follows: the zImage is preceded by header information of 64 bytes of uImage.
It is understood that zImage format, or uiimage format is merely an example of a format of a kernel image, and it is understood that embodiments of the present application do not limit a specific format of the kernel image.
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.
The data are used for transmitting information such as command lines, and specifically, the data package parameters into an ATAG_TAG mark to transmit the information; dtb is used to communicate hardware information.
In an alternative embodiment of the present application, step 102 may determine a boot address of the kernel image, and transfer the kernel image and the running data to the boot address, so as to implement booting of the operating system.
In an alternative embodiment of the present application, the method may further include: transmitting prestored environment variable parameters to a kernel of the operating system; the pre-stored environment variable parameters can be the environment variable parameters stored before the last power-off of the equipment.
Environmental variable parameters can be used to characterize frequently used parameter variables. The environment variable parameters may provide a degree of configurability to the user, such as baud rate, start-up parameters, etc. The 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 to prevent the code and data of the bootstrap program from being damaged by such a change, a block specially used for storing the environment variable parameter may be optionally reserved in the memory.
In practical applications, the environment variable parameters may be saved by a memory. The memory corresponding to the environment variable parameter may include: the memory or the external memory, or the storage corresponding to the environment variable parameter may include: static memory or dynamic memory. Alternatively, the environment variable parameter may be solidified in a nonvolatile storage medium.
In an application example of the present application, the environment variable parameters may specifically include:
bootdelay, wait seconds to perform auto-start
baudwrate, baud rate of serial console
netmask, mask for Ethernet interface
Network card physical address of ethane, ethernet card
bootfile, default download file
bootleg, boot parameters passed to kernel
bootcmd, command executed at auto-start
server ip (protocol for interconnection between networks, internet Protocol) address of server side
Ipaddr, local ip address
stdin standard input device
stdout, standard output device
stderr, standard error device
In an alternative embodiment of the present application, the method may further include: and after the operating system is started and before power failure, the environment variable parameters of the equipment are stored. In this way, the environmental variable parameters before the last power outage can be saved.
For example, after the operating system is normally started, the user triggers a command to enter the card swiping mode before power is off, and then the command to enter the card swiping mode can be updated by updating the environment variable parameters.
In summary, in the data processing method of the embodiment of the present application, after the device is powered on, first hardware corresponding to the device may be initialized, and then, if a starting mode parameter of the device meets a starting condition, a kernel of an operating system is loaded into an initialized memory, and running data corresponding to the kernel is loaded into the initialized memory. Compared with the prior art that after the primary bootstrap program finishes initializing the DDR, the secondary bootstrap program is loaded to the DDR, and the secondary bootstrap program is operated in the DDR, so that the functions of hardware initialization, memory allocation, kernel loading and the like are realized through the secondary bootstrap program.
Method embodiment II
Referring to fig. 2, a flowchart illustrating steps of a second embodiment of a data processing method of the present application, a device to which the method is applied may specifically include: a storage medium and a clock, the storage medium may specifically include: memory and peripherals; the method specifically comprises the following steps:
Under the condition that the starting mode parameters of the equipment do not meet the starting conditions, the starting mode parameters are not suitable for starting the operating system, or the user does not need to use the operating system currently; in this case, the second hardware may be initialized, the most current environment variable parameters determined, and the target start-up mode of the device entered.
The initialization of the second hardware can realize self-checking of the second hardware and setting of working parameters of the second hardware, so that the hardware can normally operate.
The second hardware includes, in addition to: in addition to the clock and the memory, the method can further comprise: and (5) peripheral equipment. The initializing of the peripheral may include: serial port, or initialization of a network port, etc.
After the initialization of the second hardware is completed, the latest environment variable parameter may also be determined. Currently, the environmental variable parameters may be saved prior to the last power down of the device. After the initialization of the second hardware is completed, the environment variable parameter can be repositioned to determine the latest environment variable parameter.
After determining the latest environment variable parameters, the method enters a target starting mode of the equipment according to the starting mode parameters of the equipment.
According to one embodiment, the start mode parameter may be a card swipe mode parameter, and the target start mode may be a card swipe mode. Entering card swiping mode can execute the upgrade of the system. Such as OTA (space download Technology), over-the-Air Technology. OTA upgrade is a standard software upgrade mode provided by the android system. The system has powerful functions and can upgrade the system without loss, mainly automatically downloads the OTA upgrade package and upgrades the OTA upgrade package through a network [ such as WIFI and 3G ], but also supports the upgrade by downloading the OTA upgrade package to the SD card. The upgrade package of the OTA is small, typically several M to tens of 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 line brush mode parameter, and the target start mode may be a line brush mode. Entering the line brush mode can execute the burning of the system. The line brush mode is generally an upgrade mode adopted by authorities and is mainly used for brushing firmware, if equipment fails to start up and the like, the line brush mode can be considered, and the card brush mode is generally used for upgrade.
In an optional embodiment of the present application, the target start mode may be a card swipe mode, and the entering the target start mode of the device according to a start mode parameter of the device may specifically include: loading the kernel of the operating system into a memory, loading the running data corresponding to the kernel into the memory, and transmitting the latest environment variable parameters to the kernel of the operating system so as to enable the operating system to be started according to the latest environment variable parameters.
In an alternative embodiment of the present application, the method may further include: after the target starting mode of the equipment is determined, the starting mode parameters are updated to the starting mode parameters corresponding to the starting conditions, so that after the equipment is powered on next time, the starting mode parameters are enabled to meet the starting conditions, and further the next starting speed of the operating system can be improved. For example, when the current startup is card swiping mode startup or line swiping mode startup, the startup mode parameter may be updated to a normal startup parameter, so that the device performs normal startup of the operating system after the next power-on.
In summary, in the data processing method of the embodiment of the present application, when the starting mode parameter of the device does not meet the starting condition, it is indicated that the device is not suitable for starting the operating system, or the user does not need to use the operating system currently; in this case, the second hardware may be initialized, the latest environment variable parameters determined, the target start-up mode of the device entered, etc.

Alternatively, the first code may be located in the SRAM, which may increase the execution speed of the first code. The second code may be located in the DDR, and since the DDR has a large capacity, the execution performance of the second code may be improved.
In summary, in the data processing method of the embodiment of the present application, the first code corresponding to step 301 and step 302 is different from the second code corresponding to step 303 to step 305, so that reasonable utilization of the memory can be achieved.
