In accordance with one aspect of the invention, the method comprises: the application program detects that the mirror image is updated, and downloads the mirror image from the server; cleaning the system application process and switching the root file system to the memory; the application program burns the upgrade mirror image to the target equipment; and after the mirror image burning is finished, the application program calls a restarting interface to restart the target equipment.
In accordance with one aspect of the invention, the functional interfaces are provided by libuprade and libsys.
In accordance with an aspect of the invention, the libuppgorde is set as an optional component of the QSDK that can be disabled in configuration options when the user has no OTA upgrade requirements.
According to one aspect of the invention, the target device enters the boot process after being restarted, and directly enters the system if no OTA marker is detected.
The implementation of the invention has the advantages that: and the OTA application program finally realizes the data access to the storage equipment by calling the functional interfaces provided by the libuprade and the libsys. Through the OTA mode, can carry out software upgrading to the equipment that distributes in all places, and needn't let the fortune maintenance personnel rush across the places. The Internet of things platform supports equipment firmware upgrading in an OTA mode, and is a means for repairing system bugs and realizing system upgrading of intelligent equipment. In the rapidly changing and developing market of the internet of things, new product requirements are constantly emerging, so that the updating requirements for intelligent hardware devices become unprecedented and high, and the devices are no longer changed as soon as being sold like traditional devices. The user is provided with better service through firmware upgrade. Further, libuppgorde is an optional component of the QSDK that can be disabled in configuration options when the user does not have OTA upgrade requirements.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Four OTA implementation modes are provided for a user to select according to the product condition of the user. The 4 modes are different in storage medium occupation, memory occupation and safety, and a user can select the modes according to specific product conditions.
Example one
Mode 1, as shown in fig. 1, wherein steps (1), (2) and (3) are implemented in an application program, which is called Downloader; steps (7), (8) and (9) are implemented in another application program, which is called update. Downloader and Updater require the user to develop themselves. An OTA upgrading implementation method based on QSDK equipment is realized by the following steps:
1. the application program detects that the mirror image is updated, and downloads the upgrade mirror image from the server;
2. after the mirror image downloading is finished, the application program sets OTA Flag;
3. calling a restarting interface by the application program to restart the target equipment;
4. restarting the target equipment, entering a Bootloader, and detecting the OTA Flag set before restarting;
5. starting Kernel0 to prepare necessary preparation for burning;
6. starting the RAMdisk and preparing for burning;
7. the application program burns the upgrade mirror image to the target equipment;
8. and after the mirror image burning is finished, the OTA Flag is cleared by the application program, then the restarting interface is called again, and the target equipment is restarted.
Example two
In the mode 2, as shown in fig. 2, after the Bootloader checks OTA Flag, kernel0 is loaded and started first. If Kernel0 fails to boot, then the backup image Kernel1 of Kernel0 will be booted. Since Kernel1 and RAMdisk are stored in the storage medium, the method 2 has a certain requirement on the capacity of the storage medium. The security of the method is high, and the scheme is recommended to be used on products taking 32M SPI Flash or eMMC as storage media. The specific process is as follows:
1. the application program detects that the mirror image is updated, and downloads the upgrade mirror image from the server;
2. after the mirror image downloading is finished, the application program sets OTA Flag;
3. calling a restarting interface by the application program to restart the target equipment;
4. restarting the target equipment, entering a Bootloader, and detecting the OTA Flag set before restarting;
5. starting Kernel0 to prepare necessary preparation for burning, and jumping to the step 7 if the starting is successful;
6. if the Kernel0 is failed to be started, the Kernel1 is started to prepare for burning;
7. starting the RAMdisk0, preparing for burning, and jumping to the 9 th step if the starting is successful;
8. if the starting of the RAMdisk0 fails, starting the RAMdisk1 to prepare for burning;
9. the application program burns the upgrade mirror image to the target equipment;
10. and after the mirror image burning is finished, the OTA Flag is cleared by the application program, then the restarting interface is called again, and the target equipment is restarted.
EXAMPLE III
1. the application program detects that the mirror image is updated, and then sets OTA Flag;
2. calling a restarting interface by the application program to restart the target equipment;
3. restarting the target equipment, entering a Bootloader, and detecting the OTA Flag set before restarting;
4. starting Kernel0 to prepare necessary preparation for burning;
5. starting Ramdisk to prepare for burning;
6. the application program downloads the upgrading mirror image from the server;
7. the application program burns the upgrade mirror image to the target equipment;
8. and after the mirror image burning is finished, the OTA Flag is cleared by the application program, then the restarting interface is called again, and the target equipment is restarted.
Example four
1. in the file system, an application program detects that the mirror image is updated, and downloads the mirror image from a server;
2. cleaning the system application process and switching the root file system to the memory;
3. the application program burns the upgrade mirror image to the target equipment;
4. and after the mirror image burning is finished, the application program calls a restarting interface to restart the target equipment.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention disclosed herein are intended to be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
