Description
Technical field
The present invention relates to smartwatch technical field more particularly to the FOTA upgrade methods and system of a kind of smartwatch.
Background technique
Mobile phone, tablet computer, portable media player, mobile internet device firmware update services generally use at present
FOTA(Firmware Over-The-Air, Firmware Over download technology) upgrading.The Firmware Over download technology liter of mobile terminal
Grade refers to that through cloud upgrade technique, for the equipment with networking function, such as mobile phone, tablet computer upgrades software, and completion system is repaired
Multiple and optimization.
The general flow of current over the air upgrading is by Network Check software upgrading version -> if any update
When software version, downloads to update after the completion of software -> preservation updates software to equipment Flash -> downloading by network and open again
Dynamic equipment -> the upgrade-system software under Bootloader mode or Recovery mode -> restarts machine after upgrading successfully,
Complete upgrading.
This method is a good scheme for having for larger capacity Flash, but use limited for Flash capacity
It is not but a good selection for the smartwatch of MCU+RTOS.Because the smartwatch of general MCU+RTOS considers cost
Program is directly executed with needs, the Flash used is usually NOR Flash, and capacity is 2M-16M, and smartwatch executes journey
Sequence and resource file will occupy 2/3 space Flash, and remaining 1/3 flash will be used to the file system for saving data.Such as
Fruit will also occupy 1/3 space according to FOTA Flash space requirement, then Flash is just used for FOTA without remaining space
?.
Therefore, the existing technology has yet to be improved and developed.
Summary of the invention
Place in view of above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a kind of FOTA of smartwatch upgradings
Method and system, it is intended to when solving smartwatch progress FOTA upgrading in the prior art, if firmware data is directly downloaded to Nor
Can there are problems that insufficient space when in Flash.

Detailed description of the invention
Fig. 1 is the flow chart of the FOTA upgrade method preferred embodiment of smartwatch of the present invention.
Fig. 2 is the structural block diagram of the FOTA upgrade-system preferred embodiment of smartwatch of the present invention.
Specific embodiment
The present invention provides the FOTA upgrade method and system of a kind of smartwatch, to make the purpose of the present invention, technical solution
And effect is clearer, clear, the present invention is described in more detail as follows in conjunction with drawings and embodiments.It should be appreciated that this
Place is described, and specific examples are only used to explain the present invention, is not intended to limit the present invention.
Referring to FIG. 1, its flow chart for the FOTA upgrade method preferred embodiment of smartwatch of the present invention.Such as figure
Shown in 1, the FOTA upgrade method of the smartwatch, comprising the following steps:
Step S100, smartwatch booting operation when, if desired to firmware upgrade when, then by FOTA update mark be written to
NOR Flash, starting system of laying equal stress on.
Step S200, start Bootloader, mark is updated according to FOTA and downloads firmware data from cloud, by firmware data
It saves into the RAM of smartwatch, NOR Flash is written into the firmware data in RAM, remove FOTA and update mark, and restart
System.
In embedded OS, bootstrap before Bootloader(, that is, system starts) it is to be transported in operating system nucleus
It is run before row.Hardware device can be initialized, establish memory headroom mapping graph, to take the hardware environment of system to one
A proper states, to get out correct environment for final call operation system kernel.In embedded systems, usually not
Have the firmware program as BIOS (note, some embedded type CPUs can also embed one section of short and small startup program), therefore entire system
The load starting task of system is just completed by BootLoader completely.
And NOR Flash is one of two kinds of main nonvolatile flash memory technologies currently on the market.Intel in 1988 first
NOR Flash technology is developed, is revolutionized originally by EPROM (Erasable Programmable Read-Only-
Memory electrically programable ROM) and EEPROM (electrically erasable read-only memory Electrically Erasable
Programmable Read-Only Memory) rule all the land situation.And then, 1989, Toshiba delivered
NAND Flash structure emphasizes the cost for reducing every bit, there is higher performance, and can pass through interface as disk
Easily upgrading.The characteristics of NOR Flash is to execute (XIP, eXecute In Place) in chip, and such application program can be with
It is directly run in Flash flash memory, it is not necessary to code be read in system RAM again.The efficiency of transmission of NOR is very high, 1 ~ 4MB's
There is very high cost-effectiveness when low capacity.
In the embodiment of the present invention, the data capacity of the NOR Flash is 2-16M.
When smartwatch operates normally, there is whether a background task regular check needs to carry out firmware in smartwatch
Upgrading, therefore detection may insure the timeliness of version updating when smartwatch operates normally.When having checked version updating,
User is reminded to update, if user selects to update, FOTA updates mark and is written to NOR Flash, restarts system update.If
User does not select to update, then only reminds user.
In step s 200, it when Bootloader starts, checks whether there is FOTA and updates mark, if there is then entering
FOTA more new technological process first sends when update and updates request command to cloud, then starts to download the data to RAM from cloud, work as number
After the completion of downloading, after checking that data are errorless, it is written to NOR Flash, FOTA upgrading mark is then removed, restarts system, into
Enter normal system.
It, can be with since the system in smartwatch is not run all due to being to carry out FOTA upgrading in Bootloader
It is used to store the firmware data of downloading using more RAM to be upgraded.Meanwhile FOTA upgrading is not take up additional Flash
Space reduces product cost.
Further, in the FOTA upgrade method of the smartwatch, the step S100 is specifically included:
Step S101, when smartwatch booting operation, then the version checking for sending firmware is instructed to cloud；
Step S102, cloud receives version checking instruction, and feeds back the latest edition number of firmware to smartwatch；
Step S103, judge whether the current version number in smartwatch is lower than the latest edition number of firmware, when intelligent hand
Current version number in table thens follow the steps S104 when being lower than the latest edition number of firmware, when the current version number in smartwatch
Not less than firmware latest edition number when then follow the steps S107;
Step S104, on the display screen of smartwatch, pop-up one prompts the user whether to carry out the prompting frame of firmware upgrade；
Step S105, whether firmware upgrade is selected to detect user, is then executed when detecting firmware upgrade instruction
Step S106 thens follow the steps S107 when firmware upgrade instruction is not detected；
Step S106, FOTA update mark is written to NOR Flash, starting system of laying equal stress on；
Step S107, terminate.
Further, in the FOTA upgrade method of the smartwatch, the step S200 is specifically included:
Step S201, start Bootloader；
Step S202, whether in NOR Flash have FOTA update mark, mark when there is FOTA to update in NOR Flash if detecting
S203 is thened follow the steps when will, thens follow the steps S207 when updating and indicating without FOTA in NOR Flash；
Step S203, smartwatch sends the downloading request of firmware data to cloud；
Step S204, smartwatch receives the firmware data from cloud, and is saved in RAM；
Step S205, judge whether the firmware data from cloud finishes receiving, then held when firmware data finishes receiving
Row step S206, S204 is then returned to step when firmware data does not finish receiving；
Step S206, NOR Flash is written into the firmware data in RAM, removes FOTA and updates mark, starting system of laying equal stress on；
Step S207, terminate.
Based on above method embodiment, the present invention also provides a kind of FOTA upgrade-systems of smartwatch.Such as Fig. 2 institute
Show, the FOTA upgrade-system of the smartwatch, comprising:
Update mark writing module 100, for smartwatch booting operation when, if desired to firmware upgrade when, then will
FOTA updates mark and is written to NOR Flash, starting system of laying equal stress on；
