Description
Technical field
The present invention relates to display technology field, more specifically, being related to a kind of booting Logo display methods, device and embedding
Enter formula equipment.
Background technology
Existing embedded device is when starting, it is often necessary to which a period of time could complete to start.During this period of time,
In order to reduce uninteresting sense when user's waiting facilities start, start-up picture is set for display, be commonly referred to as switched on Logo.Institute
State booting Logo refer to user be switched on after, program not yet start before time in, over the display show one figure
Piece, so that user appreciates, and this this be carried out at the same time the start-up course on backstage, until completing the startup of program.
In the prior art, the flow for displaying of Logo of being switched on is：After bootstrap loader (BootLoader) starts first,
Bootstrap loader can initialize embedded memory (Embedded Multi Media Card, eMMC) driving, guiding operation
System kernel (Kernel) starts；Then the driving of operating system nucleus initialization embedded memory, reading are stored in embedded
Booting Logo in memory, and the Logo that will be switched on is shown to the display of embedded device.
But inventor has found in the research process of the application, the display process of tradition booting Logo is needed by two
The initialization of secondary embedded memory driving, so as to cause booting Logo the display time take it is longer, make system for a long time at
In black state, therefore user experience is poor.
Invention content
In view of this, the present invention discloses a kind of booting Logo display methods, device and embedded device, to solve traditional skill
Present in art, it is longer that booting Logo shows that the time takes, and makes the problem of system long-time is in black state.
A kind of booting Logo display methods, including：
Embedded memory is initialized by bootstrap loader to drive；
Read the booting Logo of embedded memory memory storage；
The booting Logo is preserved to memory；
Using the operating system nucleus after startup, the booting Logo preserved in the memory is read；
The booting Logo is transmitted to the display of embedded device, to show the booting by the display
Logo。
Preferably, it before the initialization embedded memory driving by bootstrap loader, further includes：
Start the bootstrap loader.
Preferably, in the operating system nucleus using after starting, the booting preserved in the memory is read
Before Logo, further include：
The operating system nucleus is guided to start.
A kind of booting Logo display devices, including：

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a kind of booting Logo display methods, device and embedded device, to solve traditional skill
Present in art, it is longer that booting Logo shows that the time takes, and makes the problem of system long-time is in black state.
Referring to Fig. 1, a kind of work flow diagram for the Logo display methods that is switched on disclosed by the embodiments of the present invention, this method includes
Step：
Step S101, embedded memory is initialized by bootstrap loader (BootLoader) to drive；
Specifically, BootLoader is a kind of program run before operating system nucleus (Kernel) is run.Guiding adds
Hardware can be initialized, establish memory headroom mapping graph by carrying program, so as to take the software and hardware of system to a proper states, with
Just correct environment is got out for final call operation system kernel.
In embedded systems, usually there is no the firmware program as BIOS, (note, some embedded type CPUs are also in meeting
Embedding one section of short and small startup program), therefore the loading of whole system starts task and is completed completely by BootLoader.At one
In embedded system based on ARM7TDMI core, system is usually all opened when powering on or resetting at the 0x00000000 of address
Begin perform, and at this address arrange usually be exactly system BootLoader programs.
Step S102, the booting Logo of embedded memory memory storage is read；
Specifically, the English full name of embedded memory is：Embedded Multi Media Card, English are abbreviated as
EMMC, eMMC are for storing BootLoader, Kernel, be switched on Logo and file system.
The Chinese of Kernel is：Operating system nucleus, Kernel refer to the core of most of operating systems, by
It is formed in operating system for managing those parts of memory, file, peripheral hardware and system resource.Kernel usually run into
Journey, and the communication between process is provided.
Step S103, booting Logo is preserved to memory；
Wherein, memory can be embedded device hard disk in and/or be stored in USB flash drive and/or safe digital
Block in SD.
In specific stored, staff can send out different store instructions according to different application scenarios, with
Booting Logo is stored in different memories by selection.
Step S104, using the operating system nucleus after startup, the booting Logo preserved in memory is read；
Step S105, the Logo that is switched on is transmitted to the display of embedded device, to show booting Logo by display.
Wherein, the picture format that display is supported includes：The multiple formats such as BMP, JPEG, PNG and GIF.
In summary, the present invention initializes embedded memory by bootstrap loader first and drives；Secondly in reading
The booting Logo of embedded memory memory storage, and booting Logo is preserved to memory；Then using in the operating system after starting
Core reads the booting Logo preserved in memory, and the Logo that is switched on is shown to the display of embedded device.It follows that this hair
The bright initialization for only performing an embedded memory driving needs to perform embedded memory driving twice compared to tradition
For initialization, the present invention substantially reduces the display time of booting Logo, and the time that system is in black state is made to shorten, from
And improve user experience.
In addition, the flow for displaying of another booting Logo is further included in the prior art：With scheme disclosed in background technology not
With the program starts in the data direct compilation to operating system nucleus for the Logo that is switched in guiding operating system nucleus
Afterwards, the Logo that is switched on is shown to the display of embedded device by operating system nucleus.Although program Exactly-once embeds
The initialization of formula storage drive, but there are a drawbacks：If desired booting Logo is replaced, it is necessary to recompilate operation system
System kernel.And the present invention is to store booting Logo to memory, when needing replacing booting Logo, it is only necessary to change in memory and deposit
The booting Logo of storage, without recompilating operating system nucleus, in comparison, the operation that the present invention replaces booting Logo is more square
Just.
In addition, before step S101, step is further included：
Start the bootstrap loader.
In order to further optimize the above embodiments, before step S104, step is further included：
The operating system nucleus is guided to start.
