Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a method, system, terminal, and vehicle for flashing software on a vehicle screen driver board. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Currently, vehicles are equipped with increasingly advanced technology and have more complex functions. As a result, the software update frequency of ECUs (Electronic Control Units) is also increasing. This has led to the emergence of OAT (Over-the-Air Technology) services, which specifically refer to downloading new software update packages from remote servers via the internet to upgrade the system.

[0004] For example, when using smartphones, tablets, or PCs (Personal Computers) in daily life, OTA online upgrades can patch existing vulnerabilities, add many new features to the device, and provide significant improvements in operating efficiency, speed, and stability.

[0005] However, the inventors discovered that the screen driver board, which has a main control MCU (Microcontroller Unit), lacks a CAN (Controller Area Network) bus, making software updates a challenge. Updating the screen driver board usually requires removing it from the vehicle body and its casing, soldering wires, and then flashing the software via J-Link (SWD interface), or simply scrapping the faulty screen driver board and replacing it with a new one, which is not only time-consuming and labor-intensive but also costly. Summary of the Invention

[0124] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0125] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0126] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0127] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0128] Example 1:

[0129] like Figure 1 As shown, Embodiment 1 of the present invention provides a software flashing method for a vehicle screen driver board, applied to a control terminal, including the following process:

[0130] When a software update package is detected in the removable storage, a software update request is sent.

[0131] Upon receiving a software update instruction, the screen driver board terminal is flashed according to the contents of the software update package.

[0132] In this embodiment, a Boot-Loader instruction protocol is added to the IIC communication integrated in GSML2 between the host (i.e., the control terminal) and the screen driver board (i.e., the screen driver board terminal) to enable the screen driver board to update its software automatically, while the host supports USB recognition.

[0133] In this embodiment, the software update package (binary file data) of the screen driver board is placed in a mobile storage device. The host parses the binary file and then sends the data in the file to the screen driver board terminal through IIC in GSML2. The screen driver board terminal then updates its own APP software.

[0134] The host in this embodiment can recognize USB mobile storage devices (which can be Android or other operating systems such as Harmony OS), which makes updating the screen driver board more convenient.

[0135] In this embodiment, the main participants are the MCU of the screen driver board (i.e., the screen driver board terminal), the host (control terminal), and the GSML2 deserialization chip of the screen driver board. The GSML2 deserialization chip of the screen driver board mainly serves to connect the host and the screen driver board terminal, and does not actually participate in the software flashing process.

[0136] In this embodiment, the host detects and identifies software update packages in the USB mobile storage, such as naming rules and file attributes, and prompts the user that there is new software available for upgrade. The host plays a leading role in the upgrade process, controlling the upgrade status and receiving feedback from the screen driver board until the upgrade is completed. After resetting, the screen driver board works on the new version of the APP.

[0137] The screen driver terminal is mainly responsible for receiving upgrade instructions from the host and performing operations such as erasing, writing, and resetting the Flash memory according to the flashing protocol.

[0138] In this embodiment, before issuing a software update request, it is determined whether the software update package has already been updated on the screen driver board terminal. If not, a software update request is issued; if so, a software update request is not issued.

[0139] Alternatively, in some other implementations, when the screen driver board has a new upgrade requirement, the binary file to be upgraded is first packaged in a specific way (compression, encryption, naming rules and storage path, etc.) and stored in a mobile storage device. When the mobile storage device is connected to the host via USB, the host recognizes the package with the upgrade and prompts the user to upgrade. The user triggers the upgrade by touching the button.

[0140] In this embodiment, a flashing action command is sent to the screen driver terminal according to the contents of the software update package, so that the screen driver terminal executes the flashing action command after verifying that the command is correct; the flashing action command includes at least: erase, flash, and reset.

[0141] Both the host and the screen driver board send upgrade command messages according to the upgrade protocol, receive and judge the validity of the commands, execute corresponding actions (such as erasing and flashing), and send back execution result messages. They monitor the feedback results and control the upgrade steps. After the user triggers the upgrade, the host starts to send IIC upgrade messages to the screen driver board according to the upgrade protocol. The screen driver board also judges the validity of the commands according to the protocol, executes corresponding actions, and sends back execution results.

[0142] In this embodiment, assuming the loader is already in a ready state, a flashing action command is sent to the screen driver terminal according to the contents of the software update package, including:

[0143] The system queries the bootloader status. Once it receives information indicating that the bootloader is ready, it generates a flash erase command and sends it to the screen driver board terminal.

[0144] After receiving the message that the flash memory erase was successful, a command to enter programming mode is generated and sent to the screen driver board terminal;

[0145] After receiving the message to enter programming mode, send a line of binary file data of the software update package so that the screen driver terminal can write this line of binary file data to the specified address;

[0146] After all binary file data has been sent and feedback confirming successful flashing is received, send the checksum to the screen driver terminal.

[0147] After receiving the checksum matching information, a restart command is sent to the screen driver terminal to restart the screen driver terminal and complete the screen driver jump to execute the new APP program.

[0148] In some other implementations, assuming the loader is in a pre-ready state, a flashing command is sent to the screen driver terminal based on the contents of the software update package, including:

[0149] Check the loading program status. If no feedback message is received from the screen driver terminal within the timeout period, request permission from the screen driver terminal.

[0150] After receiving the authorization information from the screen driver terminal, send the first key to the screen driver terminal;

[0151] After receiving the first key from the screen driver terminal (the screen driver terminal verifies the first key), send the second key to the screen driver terminal.

[0152] After receiving the second key from the screen driver terminal (the screen driver terminal verifies the second key), check the loading program status again.

[0153] After receiving the information that the loading program is ready, a flash erase command is generated and sent to the screen driver board terminal;

[0154] After receiving the message that the flash memory erase was successful, a command to enter programming mode is generated and sent to the screen driver board terminal;

[0155] After receiving the message to enter programming mode, send a line of binary file data of the software update package so that the screen driver terminal can write this line of binary file data to the specified address;

[0156] After all binary file data has been sent and feedback confirming successful flashing is received, send the checksum to the screen driver terminal.

[0157] After receiving the checksum matching information, a restart command is sent to the screen driver terminal to restart the screen driver terminal and complete the screen driver jump to execute the new APP program.

[0162] Optionally, in the update package identification module, the software update package includes at least the naming rules and file attributes of the software update package.

[0163] Optionally, in the update package identification module, before issuing a software update request, it is determined whether the software update package has already been updated on the screen driver board terminal. If not, a software update request is issued; if so, a software update request is not issued.

[0164] Optionally, when the screen driver board has a new upgrade requirement, the binary file to be upgraded is first packaged in a specific way (compression, encryption, naming rules and storage path, etc.) and stored in a mobile storage device. When the mobile storage device is connected to the host via USB, the host recognizes the package with the upgrade and prompts the user to upgrade. The user can trigger the upgrade by touching the button.

[0165] In this embodiment, assuming the loading program is already in a ready state, the flashing control module performs screen driver terminal flashing control according to the content of the software update package, including:

[0167] Based on the contents of the software update package, a flashing command is sent to the screen driver terminal, including:

[0168] Query the loader status, and after receiving the information that the loader status is ready, generate a flash erase command and send it to the screen driver board terminal;

[0169] After receiving the message that the flash memory erase was successful, a command to enter programming mode is generated and sent to the screen driver board terminal;

[0170] After receiving the message to enter programming mode, send a line of binary file data of the software update package so that the screen driver terminal can write this line of binary file data to the specified address;

[0171] After all binary file data has been sent and feedback confirming successful flashing is received, a verification code is sent to the screen driver terminal.

[0172] After receiving the verification code matching information, a restart command is sent to the screen driver terminal to restart the screen driver terminal.

[0173] Optionally, assuming the loader is in a not-ready state, a flashing command is sent to the screen driver terminal based on the contents of the software update package, including:

[0174] Check the loading program status. If no feedback message is received from the screen driver terminal within the timeout period, request permission from the screen driver terminal.

[0175] After receiving the authorization information from the screen driver terminal, send the first key to the screen driver terminal;

[0176] After receiving the first key verification information from the screen driver terminal, send the second key to the screen driver terminal;

[0177] After receiving the second key verification information from the screen driver terminal, check the loading program status again;

[0178] After receiving the information that the loading program is ready, a flash erase command is generated and sent to the screen driver board terminal;

[0179] After receiving the message that the flash memory erase was successful, a command to enter programming mode is generated and sent to the screen driver board terminal;

[0180] After receiving the message to enter programming mode, send a line of binary file data of the software update package so that the screen driver terminal can write this line of binary file data to the specified address;

[0181] After all binary file data has been sent and feedback confirming successful flashing is received, a verification code is sent to the screen driver terminal.
