Embodiment
The various exemplary embodiments of the present invention are described in detail now with reference to accompanying drawing.It should be noted that：Unless have in addition
Body illustrates that the unlimited system of part and the positioned opposite of step, numerical expression and the numerical value otherwise illustrated in these embodiments is originally
The scope of invention.
The description only actually at least one exemplary embodiment is illustrative to be never used as to the present invention below
And its application or any restrictions that use.
It may be not discussed in detail for technology, method and apparatus known to person of ordinary skill in the relevant, but suitable
In the case of, the technology, method and apparatus should be considered as part for specification.
In shown here and discussion all examples, any occurrence should be construed as merely exemplary, without
It is as limitation.Therefore, other examples of exemplary embodiment can have different values.
It should be noted that：Similar label and letter represents similar terms in following accompanying drawing, therefore, once a certain Xiang Yi
It is defined, then it need not be further discussed in subsequent accompanying drawing in individual accompanying drawing.
With reference to shown in figure 1, illustrate the liter of the bootstrap loader provided in an embodiment of the present invention for wearing virtual reality device
Level method, comprises the following steps：
S1, virtual reality device reception upgrade command is worn, wherein, wear virtual reality described in upgrade command instruction and set
The bootstrap loader of standby upper master controller upgrades, and the first bootstrap of the bootstrap loader is stored in described wear
The memory block of virtual reality device.
In one example, the upgrade command can be that host computer is sent to and wears virtual reality device, or, institute
It can wear caused by the regular automatic upgrade mechanism built in virtual reality device to state upgrade command.
In one example, the upgrade mechanism file of the application software of master controller has the machine for triggering the upgrade command
System, master controller can automatically generate instruction institute after using the upgrade mechanism file to the application software upgrade of master controller
State the upgrade command of the bootstrap loader upgrading of master controller.
In one example, the bootstrap loader is stored in the memory block of the fixation for wearing virtual reality device
In.
S2, the master controller obtain the guiding loading journey from the upgrade mechanism file of the application software of master controller
Second bootstrap of sequence.
In one example, before step S2, the application software of master controller is obtained beforehand through modes such as downloads
Upgrade mechanism file.
In one example, before step S2, in advance by the guiding loading journey after the second bootstrap, that is, renewal
Sequence, in the upgrade mechanism file for the application software for being stored in the master controller for wearing virtual reality device.
In one example, before step S2, the second bootstrap is previously generated.The syntax format of second bootstrap
It is consistent with the syntax format of the application software file of master controller, for example, the application software file of master controller is C language text
Part, then the second bootstrap also will be C language file.If the application of the syntax format and master controller of the second bootstrap is soft
The syntax format of part file is inconsistent, can be converted into the second bootstrap and master control by means such as file crossover tools
The consistent syntax format of the application software file of device processed.By the second guiding journey consistent with the application software file syntax form
Sequence is added in application software file, then to being recompilated using software document.
In one example, the application software that second bootstrap is stored in the master controller
In upgrade mechanism file, comprise the following steps：Compile out binary file corresponding to the bootstrap loader code；By described in
Binary file is converted into the array of computer programming language file；The array is copied to should described in the master controller
With in the upgrade mechanism file of software.
S3, second bootstrap is stored in described in first bootstrap of the bootstrap loader and deposited
Storage area, replace first bootstrap.
In the embodiment of the present invention, the first bootstrap of bootstrap loader refers to wear that virtual reality device is original to be drawn
Loading procedure is led, the second bootstrap of bootstrap loader refers to the bootstrap loader after renewal.
In this step, first bootstrap is replaced with the second bootstrap, i.e., is loaded with the guiding after renewal
Program replaces original bootload program, so as to realize the upgrading of the bootstrap loader to wearing virtual reality device.
The present invention implements the upgrading scheme of the bootstrap loader for wearing virtual reality device provided so that user can be with
Voluntarily the bootstrap loader of virtual reality device is worn in upgrading.The present invention implements the guiding for wearing virtual reality device provided
The upgrading scheme of loading procedure, virtual reality device is worn without recalling, improve the upgrading efficiency of bootstrap loader, reduced
Upgrade cost.
Below with a specific example, illustrate the master controller provided in an embodiment of the present invention for wearing virtual reality device
Application software upgrade mechanism file forming method.The application software for wearing the master controller of virtual reality device is C languages
Form is sayed, bootstrap loader Bootloader is stored in the ROM of main control FX, and master is formed by following steps
The upgrade mechanism file of the application software of controller：
101st, Bootloader program codes are updated, to form the second bootstrap.
102nd, Bootloader program codes are compiled, obtain binary system " .bin " file.
The 103rd, " .bin " file is converted into the array form of C language using file crossover tool.
In the 104th, upgrade mechanism file that array after conversion is copied to the application software of master controller.
105th, the upgrade mechanism file containing the application software of the master controller of array after conversion is recompilated.
By above step 101-105, the upgrade mechanism file of the application software of master controller, and the upgrading are generated
Contain second bootstrap in mechanism file.

201st, master controller application software upgrade order is sent to master controller by host computer；Master controller receives master
After controller application software upgrade order, the upgrade mechanism file of the application software of master controller is obtained, restarts master controller, it is complete
Worked into application software upgrade.
202nd, bootloader program upgrade commands are sent to master controller by host computer, master controller receives
After bootloader program upgrade commands, the bootloader programs (second after renewal are obtained from the upgrade mechanism file
Bootstrap).
203rd, the bootloader programs (the second bootstrap) after renewal are stored in the original bootloader journeys of storage
In the memory block of sequence (the first bootstrap), to replace original bootloader programs (the first bootstrap), master control is restarted
Device processed, complete bootstrap loader upgrade job.
The present invention implements the upgrading scheme of the bootstrap loader for wearing virtual reality device provided so that user can be with
Voluntarily the bootstrap loader of virtual reality device is worn in upgrading.The present invention implements the guiding for wearing virtual reality device provided
