DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0015] Due to the different application scenarios of traditional routers and computing power routers, both types of routers are usually deployed simultaneously in the existing network. Traditional routers use NAND Flash to store firmware, operating systems, and other related software; computing power routers usually integrate eMMC storage, which has a large storage space and fast data read and write speeds, allowing users to directly store data on the router. NAND Flash storage and eMMC storage have different performance characteristics and different management methods, belonging to heterogeneous storage devices. For heterogeneous storage devices, relevant function development and software maintenance for network upgrade often need to be carried out separately, thus increasing the complexity of development and maintenance.

[0016] In view of the problems existing in the development and maintenance of the above-mentioned heterogeneous storage devices, embodiments of the present application provide a method for compatible heterogeneous storage devices, which calls corresponding device tree source files, file systems, and application programs according to different types of heterogeneous storage devices to ensure the compatibility of at least two heterogeneous storage devices, thereby helping to reduce the management complexity of heterogeneous storage devices and improve the development and maintenance efficiency.

[0017] Figure 1A flowchart of a method for compatible heterogeneous storage devices provided by some embodiments of the present application is shown. The execution subject of the method can be a software system running on a terminal device or a server, wherein the terminal device can be a device such as a personal computer, or a mobile terminal device such as a mobile phone, a tablet computer, a vehicle-mounted device, a medical device, etc. The terminal device can be a terminal device used by a user. The server can be an independent server or a server cluster composed of multiple servers. Moreover, the server can be a background server of a certain business, or a background server of a certain platform or application (such as a data center, a cloud platform, a monitoring system, etc.). As shown in the figure, the method 100 can include the following steps: Step 101: a target storage device is read from at least two heterogeneous storage devices by using boot loaders preset in at least two heterogeneous storage devices to obtain target identification information of the target storage device.

[0018] Among them, at least two heterogeneous storage devices include two or more of NAND Flash, eMMC, Universal Flash Storage (UFS), and Dynamic Random-Access Memory (DRAM); the target identification information can be the type, name, device identifier, etc. of the target storage device, or it can be parameter information related to the target storage device for characterizing the type of the storage device.

[0019] In an exemplary embodiment, in an embedded system, different storage devices (such as NAND Flash and eMMC) use different ROM codes (i.e., boot codes fixed in the storage devices). After the software system is powered on, it performs basic initialization of the processor and identifies and loads the bootloader into the on-chip RAM. Since the ROM code needs to be fixed in the chip during burning, when the boot loader U-Boot is burned in the factory, the U-Boot burned in the NAND Flash and eMMC storage is different. Different storage types are integrated into the parameters passed by U-Boot to the Linux kernel, and the software system can automatically detect different storage devices at startup.

[0020] Step 102: Determine a target device tree source file having a first calling relationship with the target identification information, a target file system having a second calling relationship with the target identification information, and a target application having a third calling relationship with the target identification information.

[0021] Continuing with the above embodiment, the Linux kernel can pre-configure the device tree source files (DTS) of NAND Flash and eMMC. When the kernel starts, it selects and calls different DTS according to the parameters passed by U-Boot; the file systems of NAND Flash and eMMC are pre-configured in the Linux file system. When Linux starts, different file systems are formatted according to the parameters passed by U-Boot and the different storage device types recognized; the application programs of NAND Flash and eMMC are pre-configured in the software system. After the software system starts, different application programs are called according to the different storage device types recognized by U-Boot, so as to adapt the corresponding target device tree source file, target file system and target application program according to the detected target storage device, to ensure the stable operation and efficient management of the software system. Among them, the target storage device can be NAND Flash or eMMC.

[0022] Step 103: Parse the target storage device through the target device tree source file, target file system and target application program to process the data stored in the target storage device.

[0023] Continuing with the above embodiment, parse NAND Flash or eMMC through the target device tree source file, target file system and target application program to process the data stored in the corresponding storage device.

[0024] In this way, corresponding device tree source files, file systems and application programs are called according to different types of heterogeneous storage devices to ensure the compatibility of at least two heterogeneous storage devices, which is conducive to reducing the management complexity of heterogeneous storage devices and improving the development and maintenance efficiency. Taking at least two heterogeneous storage devices as NAND Flash and eMMC as an example, based on the original software and hardware solutions, without additional hardware modifications, the same software system is made compatible with NAND Flash and eMMC with minimal impact, which is conducive to reducing the management complexity of traditional routers and computing power routers and improving the development and maintenance efficiency.

[0025] In some embodiments, the above-mentioned target device tree source file is one of the device tree source files of at least two pre-set heterogeneous storage devices, and there is a first call relationship between the identification information of the at least two heterogeneous storage devices and each device tree source file; the above-mentioned target file system is one of the file systems of at least two pre-set heterogeneous storage devices, and there is a second call relationship between the identification information of the at least two heterogeneous storage devices and each file system; the above-mentioned target application program is one of the application programs of the at least two pre-set heterogeneous storage devices, and there is a third call relationship between the identification information of the at least two heterogeneous storage devices and each application program.

[0026] Among them, the device tree source file can be configured in the operating system kernel of the software system, and the operating system kernel includes but is not limited to Linux kernel, Windows NT kernel, BSD kernel, XNU kernel, etc.

[0027] In an exemplary embodiment, the user configures the DTS of NAND Flash and the DTS of eMMC in the Linux kernel, obtains the configured DTS of NAND Flash and the DTS of eMMC, and determines the first call relationship between the identification information of the two storage devices of NAND Flash and eMMC and each DTS, so that when the software system starts, different DTSs can be called according to the identification information of different storage devices.

[0028] In another exemplary embodiment, NAND Flash usually uses the ubi file system, and eMMC usually uses the ext4 file system. The user can configure the ubi file system and the ext4 file system in the Linux file system, obtain the file systems configured by the user, and determine the second call relationship between the identification information of the two storage devices of NAND Flash and eMMC and each file system, so that when the software system starts, different file systems can be formatted according to the identification information of different storage devices.

[0029] In another exemplary embodiment, the NAND Flash storage usually contains application programs related to the data forwarding function. Since the eMMC storage has a large storage space and fast data read and write speeds, it is usually integrated in the computing power router, so it will also additionally contain a computing power program that is interconnected with the computing power platform. The user can pre-configure the application programs of NAND Flash and eMMC storage in the software system, obtain the application programs configured by the user, and determine the third call relationship between the identification information of the two storage devices of NAND Flash and eMMC and each application program, so that when the software system starts, different application programs can be called according to the identification information of different storage devices.

[0030] By the above steps, configuring the device tree source files, file systems, application programs, and call relationships of at least two heterogeneous storage devices can ensure the compatibility of at least two heterogeneous storage devices, enabling the same software system to be compatible with at least two heterogeneous storage devices, thereby facilitating the reduction of the management complexity of heterogeneous storage devices and improving the development and maintenance efficiency.

[0031] In some embodiments, the device tree source files of the above at least two heterogeneous storage devices are configured based on the first difference information of the at least two heterogeneous storage devices.

[0032] In an exemplary embodiment, if the DTS of NAND Flash includes parts A, B, C, and D, and the DTS of eMMC contains parts A, B, C, and E, where A, B, and C are the configurations common to the two storage devices, and D and E are the first difference information of the two storage devices. When the user inputs a first operation instruction, the software system configures the first difference information of NAND Flash and eMMC, namely D and E, so as to generate the DTS of NAND Flash and eMMC.

[0033] By this means, configuring the device tree source files of the storage devices based on the first difference information of the heterogeneous storage devices can avoid duplicate development of the functions of at least two heterogeneous storage devices and improve the development efficiency.

[0034] In some embodiments, the file systems of the above at least two heterogeneous storage devices are configured based on the second difference information of the at least two heterogeneous storage devices.

[0035] In an exemplary embodiment, if the file system of NAND Flash includes parts F, G, and K, and the file system of eMMC contains parts F, G, and L, where F and G are the configurations common to the two storage devices, and K and L are the second difference information of the two storage devices. When the user inputs a second operation instruction, the software system configures the second difference information of NAND Flash and eMMC, namely parts K and L, so as to generate the file systems of NAND Flash and eMMC.

[0036] By this means, configuring the file systems of the storage devices based on the second difference information of the heterogeneous storage devices can avoid duplicate development of the functions of at least two heterogeneous storage devices and improve the development efficiency.

[0037] In some embodiments, the application programs of the above at least two heterogeneous storage devices are configured based on the third difference information of the at least two heterogeneous storage devices.

[0038] In an exemplary embodiment, suppose the application program of the NAND Flash includes parts M, N, O, and P, and the application program of the eMMC includes parts M, N, Q, and R, where M and N are the configurations common to the two storage devices, and O, P and Q, R are the third difference information of the two storage devices. When the user inputs a second operation instruction, the software system configures the third difference information of the NAND Flash and the eMMC according to the input, that is, parts O, P, Q, and R, so as to generate the application programs of the NAND Flash and the eMMC.

[0039] In this way, based on the third difference information of heterogeneous storage devices, the application programs of the storage devices can be configured, which can avoid the repeated development of the functions of at least two heterogeneous storage devices and improve the development efficiency.

[0040] In some embodiments, in step 103 above, after parsing the target storage device through the target device tree source file, the target file system, and the target application program to process the data stored in the target storage device, it further includes: In response to obtaining the system upgrade file, upgrade the device tree source file, the file system, and the application program of at least two heterogeneous storage devices to the versions included in the system upgrade file.

[0041] In an exemplary embodiment, when the system upgrade file is packaged, it includes the Linux kernel, the Linux file system, and the application program, while U-Boot is burned in the factory and is not included in the system upgrade file. After modifying functions such as network connection, the system upgrade file can be used for the upgrade of both the NAND Flash and the eMMC at the same time, avoiding the repeated development of functions and the maintenance of multiple upgrade versions.

[0042] Through the above steps, the compatibility problem of the same software system on different storage devices (NAND Flash and eMMC) can be effectively solved, which provides great convenience for the software version development and maintenance of network devices such as smart home routers or gateways. At the same time, through this method, not only the complexity of the hardware configuration is simplified, but also the flexibility and maintainability of the software system are improved.

[0043] Figure 2 shows a schematic structural diagram of a system compatible with heterogeneous storage devices provided by some embodiments of the present application. The system compatible with heterogeneous storage devices can implement all or part of the content in the Figure 1 illustrated embodiment.

[0049] In some embodiments, the above-mentioned system 200 further includes: The operating system kernel unit 220 is used to configure the device tree source file of the at least two heterogeneous storage devices, and there is a first call relationship between the identification information of the at least two heterogeneous storage devices and each device tree source file; The system file configuration unit 230 is used to configure the file system of the at least two heterogeneous storage devices, and there is a second call relationship between the identification information of the at least two heterogeneous storage devices and each file system; An application configuration unit 240, configured to configure applications for the at least two heterogeneous storage devices, where there is a third call relationship between the identification information of the at least two heterogeneous storage devices and each application.

[0050] In an exemplary embodiment, taking the at least two heterogeneous storage devices as NAND Flash and eMMC as an example, as Figure 3 shown, the software system is divided into four parts: a bootloader configuration unit 310, an operating system kernel unit 320, a system file configuration unit 330, and an application configuration unit 340. The bootloader configuration unit 310 is configured with the U-Boot of NAND Flash and the U-Boot of eMMC; the operating system kernel unit 320 is configured with the DTS of NAND Flash and the DTS of eMMC; the system file configuration unit 330 is configured with the file system of NAND Flash and the file system of eMMC; the application configuration unit 340 is configured with the applications of NAND Flash and the applications of eMMC.

[0051] Assume that the target storage device is NAND Flash. When the software system starts, the bootloader configuration unit 310 reads the NAND Flash, and by passing the NAND Flash-related parameters to the operating system kernel unit 320, dynamically adapts the corresponding DTS, file system, and application to process the data stored in the NAND Flash.

[0052] The embodiment of the present application provides a system compatible with heterogeneous storage devices, including a bootloader configuration unit; the bootloader configuration unit reads a target storage device from the at least two heterogeneous storage devices through the bootloaders of the preset at least two heterogeneous storage devices, and obtains the target identification information of the target storage device; the system determines a target device tree source file having a first call relationship with the target identification information, a target file system having a second call relationship with the target identification information, and a target application having a third call relationship with the target identification information; and parses the target storage device through the target device tree source file, the target file system, and the target application to process the data stored in the target storage device.
