FIG. 6 is a schematic structural diagram of a terminal device in an embodiment of the present invention.

The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 1 , it is a schematic flowchart of a method for upgrading a system of a terminal device according to a first embodiment of the present invention. The system upgrade method shown in this embodiment includes the following steps:

In step S10, the terminal device receives a first system file during operation. The event of receiving the first system file does not affect the current working state of the terminal device.

The first system file is a system upgrade file, and the version model is higher than the version model of the system file currently running by the terminal device. In this embodiment, the terminal device is a smart TV. The Internet TV company server updates the system of the client TV, provides an upgrade file, and pushes the upgrade file to the client through the network. The process of receiving the first system file while the TV is working is in the background and does not affect the broadcast of the TV program.

Step S11, determining whether the memory partition occupied by the currently running second system file is the first memory partition or the second memory partition.

The memory is pre-divided into a first memory partition and a second memory partition. The two memory partitions are independent of each other and are not affected by each other, and are used to save system files. The memory has a certain storage space in the terminal device, and the power is not powered off. Physical memory of lost data, such as hard disk, flash memory flash, etc.

Further, the memory is equally divided into a first memory partition and a second memory partition, that is, the storage spaces of the two memory partitions are the same. Of course, the manner in which the first memory partition and the second memory partition are divided is not limited to this.

Step S12: Save the received first system file to a memory partition that is not currently occupied in the first memory partition and the second memory partition.

In step S12, the second system file that is running when the terminal device is working is saved in one of the two memory partitions, and the downloaded first system file is saved in another partition (hereinafter referred to as a free partition). . If the free partition has originally saved a system file with a lower version of the model, the first system file overwrites its original system file.

In step S13, if the user's upgrade command is received during the power-off restart, the first system file is run to complete the system upgrade.

When the terminal device is powered off and then restarted, the input user's upgrade instruction is received, and the first system file is run to complete the system upgrade.

Optionally, if the upgrade instruction of the user is not received when the power is turned off and restarted, the second system file that is operated before the power failure is run. In the system upgrade method of the terminal device in the embodiment of the present invention, the memory is divided into the first memory partition and the second memory partition in advance, and the system file loaded when the terminal device works is saved in one of the memory partitions, and the background is The system file that receives the upgrade is saved in another memory partition, and the two do not affect each other, so that the download of the upgraded system file is completed while the terminal device is working, but the user's use is not affected. And the next power off After the machine is received, the upgraded system file can be directly run when receiving the instruction that the user agrees to upgrade, and the user is not required to wait for the download, thereby speeding up the system upgrade process and improving the user experience. Further, the two memory partitions save different versions of the system files, and may also be supported by the other system file when one of the system files is damaged, thereby improving the system stability of the terminal device.

Please refer to FIG. 2, step S13, that is, if the user's upgrade instruction is received during the power-off restart, the first system file is run to complete the system upgrade, which is implemented by the following steps:

Step S13a, when the power is turned off and restarted, and when the user's upgrade instruction is received, the version number of the system file saved in the first memory partition and the second memory partition is compared. In actual application, when the power is restarted, the system will Ask the user whether to upgrade, that is, whether to upgrade the dialog box, the user clicks to agree to upgrade, the system receives the user's upgrade instructions.

In step S13a, since the terminal device has completed the download of the first system file before the power is turned off, when the user's upgrade command is received after the power failure restart, the terminal device should read the first memory by the upgrade command. The version number of the system file saved in the body partition and the second memory partition, and the system file with the higher version model is selected as the system file for boot loading, and the system file loaded into the selection is directly guided to implement the system upgrade. The version model of the system file is written to the chunk header header file of the memory partition, and the boot loader can obtain the version model of the saved system file from the chunk header header file of the memory partition.

Step S13b, running a system file with a higher version (first system) File), complete the system upgrade.

Referring to FIG. 3, after the first system file is saved to the first memory partition and the memory partition that is not occupied in the second memory partition, the method specifically includes:

Step S12a, modifying the status flag bit corresponding to the memory partition in which the first system file is saved to the first state. The first state is used to identify the system file saved in the memory partition as the latest downloaded system file.

Step S13, that is, if the user upgrade command is received during the power-off restart, the first system file is executed to complete the system upgrade, which is specifically implemented by the following steps:

Step S130a: detecting, when the power is turned off, whether the status flag bit of the first memory partition or the second memory partition is in the first state. When it is detected that the status flag bit of the first memory partition or the second memory partition is in the first state, the process proceeds to step S131a; when the first memory partition and the second memory partition are in the status flag bit If it is not the first state, the process proceeds to step S14.

For example, in step S130a, when the power is turned off, the boot loader needs to check the status value of the status flag bit corresponding to the first memory partition and the second memory partition, if one of the two memory partitions When the status flag bit of the first state is the first state, it indicates that the system file saved by the memory partition is the latest downloaded system file, that is, the system file for upgrading. At this point, you need to ask the user whether to upgrade the system. If the status flag bits of the two memory partitions are not in the first state, there is no newly downloaded system file in the memory. At this point, the preset will run the previous one. System file that runs once. The boot loader is in the second state by recording the status flag corresponding to the memory partition, indicating that the saved system file has been run last time, that is, before the power is cut off. Therefore, the bootloader only needs to determine if the status flag bit in the two memory partitions is in the second state to determine if its saved system file has been run before powering down.

Step S131a, comparing the version models of the system files saved by the first memory partition and the second memory partition.

Specifically, when the status flag bit of one of the first memory partition or the second memory partition is detected as the first state, it indicates that the terminal device has downloaded and installed the system upgrade file. At this time, by prompting the prompt information dialog box to generate a prompt to prompt the user to upgrade to the first system file, for example, the prompt information dialog box includes "agree" and "cancel", according to the user's operation on the information dialog box. Whether to receive the upgrade instruction. For example, when it is detected that the user clicks or touches the above "agree", that is, receives the upgrade command, the version model of the system file saved by comparing the first memory partition and the second memory partition is executed.

Step S132a, running a system file with a higher version of the version to complete the system upgrade.

In step S14, the system file (second system file) that is operated before the power failure is operated.

When the power is restarted, if the upgrade command is not received, the system file running before the power failure is directly operated; and when the status flag bits of the first memory partition and the second memory partition are not the first state, Run the system file that was run before the power failure.

Referring to FIG. 4, step S131a, that is, before comparing the version models of the system files saved by the first memory partition and the second memory partition, the method further includes:

In step S15, it is verified whether the first system file stored in the first memory partition or the second memory partition is legal. If yes, the process proceeds to step S131a. Otherwise, it proceeds to step S14.

In step S15, the system file is checked before comparing the system file version models, and it is determined whether the system file saved in the first memory partition and the second memory partition is correct and legal, in order to verify the newly downloaded system file. Whether the version of the (first system file) is suitable for the terminal device to prevent the system from crashing after loading and not suitable for the terminal device. Therefore, by setting step S15, the terminal device can be forced to not upgrade to the new version when the downloaded first system file fails, and the original, lower version of the system file can be used.

Further, when the terminal device completes the system upgrade, the state flag bit corresponding to the memory partition of the first system file is also modified to a second state; wherein the second state is used to identify the memory partition. The saved system file has been run.

Further, if the downloading of the first system file is not completed when the terminal device is powered off, the memory partition occupied by the currently running system file is recorded as a preset partition, and the download process of the first system file is recorded. When the working state is restored (when restarting), the system file saved in the preset partition is run, and the first system file is continuously downloaded according to the recorded downloading process.

The following describes the working principle of the system file in the terminal device loading memory.

Please refer to FIG. 5 at the same time, which is a schematic structural diagram of a memory according to an embodiment of the present invention. The AP Bin Code area is the first memory partition, and the AP Bin Code area 2 is the second memory partition. As described above, when the first system file is saved to the free partition, the chunk header header file of the free partition is written with the version number and the check code as the identifier.

Further, the Bank1-PM area is used to record and save the memory partition used by the terminal device before the power-off restart. In the case of a non-power-off restart (warm-on), the control circuitry (not shown) of the terminal device selects to start the terminal device from the system file saved in the last used memory partition recorded in Bank1-PM.

The Bank0-Sboot area is used to save the boot loader. The boot loader is used to verify the data stored in the first memory partition and the second memory partition of the memory when the terminal device is booted. Loading the system file saved in the first memory partition or the second memory partition to complete the startup of the terminal device. Specifically, the boot loader detects the status flag bits of the first memory partition and the second memory partition, verifies the legality of the saved system file, compares the version of the system file, and detects the user's upgrade instruction. And combined with the detection results of the above four conditions, the selected memory partition is finally determined. Further, the detection priority order, the combination manner, and the like of the four conditions may be set, so that the boot loader may perform one or more conditions on the terminal device each time the power is turned off and restarted. Detect and judge, select the boot memory partition.

Further, the instruction file format of the memory boot loader is as follows: ab cde fgh

The data recorded by the first two digits (ab) is used to indicate the selected memory partition. For example, if the data of the first two meta-records is 01, the selected memory partition is the first storage partition, and the first two digits. If the recorded data is 10, the selected memory partition is the second memory partition. Further, the data recorded by the first bit (a) may also be used to represent the selected memory partition. For example, 10 indicates that the selected memory partition is the first storage partition, and 00 indicates that the selected memory partition is the second memory partition. .

The data recorded by the middle three bits (cde) and the last three bits (fgh) are respectively used to indicate the states of the first memory partition and the second memory partition (or the second memory partition and the first memory partition), The status includes: the first status (whether the upgrade is successful), and the second status (whether it is running before power off). For example, when cde is 000 respectively, it indicates that the first memory partition is upgraded successfully, and the first system file is saved; when fgh is 111 respectively, it indicates that the second memory partition is not upgraded, and runs before power off.

For example, before the power is cut off, the terminal device downloads and saves the first system file in the first memory partition, so the first system file is the latest downloaded system file, and the second memory partition is saved in the running. The second system file. Then, the bootloader command data at this time is 10 000 111. Boot load after power off and restart After the program determines the system upgrade by the verification as described above, and selects to run the first system file in the first memory partition to complete the system upgrade, the instruction data is modified to 01 111 111. After the terminal device does not download the new system file after this startup, the command data of the boot loader remains unchanged. When the power is turned off again, the boot loader directly runs the first system file in the first memory partition according to the instruction data 01 111 111.

Please refer to FIG. 6 , which is a schematic structural diagram of a terminal device according to an embodiment of the present invention.
