[0038] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0039] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0040] The main solution of the embodiment of the present application is: controlling the plurality of chip domains to execute corresponding program burning tasks in sequence according to a preset program burning script.

[0041] Currently, a manual burning method is usually used to burn the vehicle-mounted SOC. However, the manual burning method requires a lot of manual switching of the chip domain that needs to be burned. The process is cumbersome and prone to errors, which may lead to production accidents.

[0042] Based on the present application scheme, the vehicle-mounted program burning process is simplified by pre-setting the program burning script, thereby reducing manual intervention; through the program burning script, several chip domains are controlled in turn to execute corresponding program burning tasks, and each chip domain can be automatically switched to complete the program burning task, thereby ensuring the accuracy of vehicle-mounted program burning while improving the efficiency of vehicle-mounted program burning.

[0043] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle-mounted program burning system, etc. The following takes the vehicle-mounted program burning system as an example to illustrate this embodiment and the following embodiments.

[0044] Based on this, the embodiment of the present application provides a method for burning a vehicle program, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle program burning method of the present application.

[0045] In this embodiment, the vehicle-mounted program burning method is applied to the vehicle-mounted SOC, and the vehicle-mounted SOC establishes a communication connection with the vehicle-mounted program burning system. The vehicle-mounted program burning method includes step S100:

[0046] Step S100, controlling the plurality of chip domains in sequence according to a preset program burning script to execute corresponding program burning tasks.

[0047] It should be noted that the vehicle-mounted program burning method proposed in this application is used in the scenario of program burning on the vehicle-mounted SOC in intelligent driving. Existing intelligent driving hardware usually uses a SOC that contains both an ARM chip and an MCU chip, wherein the ARM chip may include a GPU (Graphic Processing Unit) and is used to process high-computing power scenarios, such as image acquisition and processing; the MCU chip uses a real-time operating system or no operating system to process functions that require rapid response, such as vehicle regulations and safety. In order to increase the computing power of the SOC, the currently commonly used intelligent driving SOCs all contain dual-chip domains.

[0048] The vehicle-mounted SOC with the above architecture can meet the two requirements of large vehicle-mounted computing power and fast response, but it will also make the burning of SOC program more complicated. Figure 2 , Figure 2 This is a schematic diagram of the manual burning process of the vehicle program; Figure 2As shown, the method commonly used in the industry for burning this type of vehicle-mounted SOC is to first send instructions to the control port (serial port) of the MCU chip to control the ARM chip to enter the recovery mode (such as recovery mode), and then burn the ARM side after manual confirmation of success. If the vehicle-mounted SOC system contains a structure of multiple sets of ARM chips and MCU chips (a combination of a set of ARM chips and MCU chips is usually called a chip domain), it is necessary to take the above steps for each domain separately, and it is necessary to manually switch to the burning interface of another chip domain after completing the burning of one chip domain, because the existing burning program cannot identify which chip domain the multiple burning interfaces belong to. However, the more complex the structure of the intelligent driving SOC, the less efficient the current burning method will be, because it involves a lot of manual switching work, so the chance of error will be higher.

[0049] Based on the above considerations, the present application proposes a method for burning a smart driving vehicle SOC through a preset program burning script. Figure 3 , Figure 3 A simplified flowchart of a program burning script according to an embodiment of the present application; Figure 3 As shown, the solution proposed in this application can realize one-click execution of program burning, and there is no need to manually switch the hardware interface during the burning process, nor is there any need to operate the ARM and MCU of each chip domain in the vehicle SOC separately, which simplifies the burning process of the intelligent driving SOC, improves the burning efficiency, and reduces the error rate.

[0050] In addition, it should be noted that before the on-board program burning system burns the on-board SOC, it is necessary to determine that the on-board SOC meets the preset hardware burning conditions. The hardware burning conditions are as follows: it is necessary to prepare an on-board SOC for burning, which includes a chip domain composed of an MCU chip and an ARM chip; it is necessary to ensure that the computer carried by the on-board program burning system is powered on, and at the same time ensure that the on-board SOC is powered on; the version of the computer carried by the on-board program burning system can choose the operating system Linux5.0 or above. Among them, this embodiment does not specifically limit the computer version model, but it is necessary to support the operation of the program burning script during the actual implementation process; it is also necessary to prepare a sufficient number of connection cables, the connection cables include MCU communication cables and ARM communication cables, and each additional chip domain in the on-board SOC requires the number of connection cables to be doubled. In addition, before the program burning script is executed, the MCU communication cable and the ARM communication cable need to be connected to the on-board SOC and the computer.

[0051] Furthermore, the preset program burning script includes a command transmission function, and the command transmission function is used to perform serial port read and write operations on the MFU chip and ARM chip of each of the several chip domains.

[0052] It should be noted that the command transmission function can be constructed by a command line environment based on the Bash command, wherein Bash is a shell (command line environment) of the Linux system. The bash command is directly used to implement serial port reading and writing, and no additional library files need to be installed. The system requirements are low and the compatibility is relatively good. Among them, the serial port reading and writing operations can include operations such as sending sleep, waking up, and reading SOC status.

[0053] Based on this, the program burning script can process the serial port communication function and the recovery result identification function through a Bash-based script, wherein the function of processing serial port communication can include stably sending recovery commands to the MCU, and recovery is used to identify whether the ARM chip enters recovery mode, so that the program burning script starts executing the program burning task only when the ARM chip enters recovery mode.

[0054] In this embodiment, the plurality of chip domains are controlled in sequence according to a preset program burning script to execute the corresponding program burning task. The vehicle program burning process is simplified by presetting the program burning script, thereby reducing manual intervention; the program burning script controls the plurality of chip domains in sequence to execute the corresponding program burning task, and can realize automatic switching of each chip domain to complete the program burning task, thereby ensuring the accuracy of vehicle program burning while improving the efficiency of vehicle program burning.

[0055] In a feasible implementation manner, before the step of sequentially controlling the plurality of chip domains according to a preset program burning script to execute corresponding program burning tasks, steps S10 to S20 may be included:

[0056] Step S10, obtaining a chip domain queue to be burned;

[0057] It should be noted that, first, a data structure needs to be defined to store the chip domain information to be burned. In this embodiment, the data structure storing the chip domain to be burned can be a queue, and each element in the queue represents a chip domain and contains relevant information of the chip domain.

[0058] Step S20, setting a burning port switching function according to the device identification corresponding to each chip domain in the chip domain queue to be burned, wherein the burning port switching function is used to switch the chip domain according to the device identification.

[0059] Specifically, the queue of chip domains to be burned is traversed, and for each chip domain, the corresponding device identifier is parsed. The device identifier is usually used to uniquely identify a device or an interface on a device. More specifically, the device identifier can be set according to the serial port name.

[0060] In this implementation, a chip domain queue to be burned is obtained; according to the device identification corresponding to each chip domain in the chip domain queue to be burned, a burning port switching function is set, and the burning port switching function is used to switch the chip domain according to the device identification. This embodiment realizes automatic switching of the burning port by setting the burning port switching function. When multiple chip domains need to be burned, manual intervention can be effectively avoided, and the burning efficiency of the vehicle program is improved while ensuring the accuracy of the vehicle program burning.

[0061] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 4 , Figure 4 This is a flow chart of the second embodiment of the vehicle program burning method of the present application; Figure 4 As shown, the plurality of chip domains are sequentially controlled according to a preset program burning script to execute corresponding program burning tasks. Step S100 may include steps S1001 to S1004:

[0062] Step S1001, calling the burning port switching function according to the program burning script to determine the current chip domain to be burned from the chip domain queue to be burned;

[0063] After setting the program burning script, it is necessary to read the instructions and configuration parameters that need to be executed currently from the program burning script; according to the program burning script, call the previously set burning port switching function, the burning port switching function first checks the chip domain queue to be burned, and determines the current chip domain to be burned from the chip domain queue to be burned according to the device identification.

[0064] Step S1002, calling a preset single-domain burning function according to the program burning script, and controlling the current chip domain to be burned to execute a corresponding target program burning task based on the single-domain burning function;

[0065] This embodiment uses the current chip domain to be burned determined in step S1001 to call the preset single domain burning function. The single domain burning function controls the hardware device to perform the burning task of the target program on the current chip domain to be burned according to the preset burning parameters and steps. It should be noted that during the burning process, it is necessary to monitor the progress and status of the burning to ensure that the burning process proceeds normally.

[0066] Step S1003, when the program burning task corresponding to the current chip domain to be burned is executed successfully, the burning port switching function is called to determine a new current chip domain to be burned, and the step of calling a preset single domain burning function according to the program burning script to control the current chip domain to be burned to execute the corresponding target program burning task is returned to the step of controlling the current chip domain to be burned to execute the corresponding target program burning task until the preset program burning stop condition is met;

[0067] After the burning task of the current chip domain to be burned is completed, check whether the burning result is successful. More specifically, it can be determined by reading the status of the device or returning information. If the current burning task is successful, call the burning port switching function again to determine the next chip domain to be burned. At the same time, return to step S1002, call the single domain burning function and execute the corresponding burning task according to the new information of the current chip domain to be burned. Repeat steps S1002 and S1003 until the preset program burning stop condition is met.

[0068] It should be noted that the program burning stop conditions may include that all chip domains have been burned, the maximum burning time limit has been reached, an error has occurred, etc.

[0069] Step S1004, obtaining the program burning result.

[0070] It should be noted that the program burning result may be the domain name of all chip domains that have completed program burning or the time consumed to complete program burning, so as to serve as a basis for judging the efficiency of program burning.

[0071] In a feasible implementation manner, the preset single-domain burning function is called according to the program burning script, and based on the single-domain burning function, the current chip domain to be burned is controlled to perform the corresponding program burning task, and step S1002 may include steps S10021 to S10024:

[0072] Step S10021, calling a preset single-domain burning function according to the program burning script, and sending a recovery instruction to the microcontroller unit MCU chip corresponding to the current chip domain to be burned based on the single-domain burning function, so as to control the advanced instruction set reduced computing ARM chip corresponding to the current chip domain to be burned to enter a recovery mode;

[0073] Exemplarily, the program burning system sends a recovery command (such as a recovery command) to the serial port of the MCU chip to enter the recovery mode, assuming that the serial port identifier of the MCU chip is / ttyACM1 and / ttyACM3 by default, and assuming that the chip domains that need to be burned are domain A and domain B. When burning domain A, send a recovery command to / ttyACM1; when burning domain B, send a recovery command to / ttyACM3. It should be noted that in order to prevent the default port from being occupied, other serial port devices cannot be installed on the burning computer.

[0074] Step S10022, executing the recovery mode confirmation instruction to obtain the serial port interface bus USB device information;

[0075] After sending the recovery command to the serial port of the MCU chip, it is necessary to identify whether the ARM chip in the same chip domain has entered the recovery mode. It should be noted that the program burning script can only be executed on devices that have entered the recovery mode. After sending the recovery command, the corresponding chip domain will enter the recovery mode, but there is also a certain probability that the recovery mode will fail, so before burning the current chip domain to be burned, it is necessary to confirm whether the corresponding domain is in recovery mode. Execute the "lsusb" command on the vehicle program burning system. This command is used to display USB-related information and obtain the USB device information of all USB devices. Among them, USB devices refer to all external devices connected to the vehicle program burning system through the serial interface bus. In the scenario of burning the vehicle SOC system, the USB device is generally a controller device that carries the vehicle SOC system (including the chip domain composed of the MCU chip and the ARM chip), such as the power domain controller, chassis domain controller, etc.

[0076] In addition, in the present embodiment, the maximum number threshold value of sending the recovery instruction to the serial port of the MCU chip can be set. When the number of times the recovery instruction is sent to the serial port of the MCU chip is less than the maximum number threshold value, as long as the ARM chip successfully enters the recovery mode after the recovery instruction is sent once, the next step is immediately entered, that is, step S10022 is entered; if the number of times the recovery instruction is sent to the serial port of the MCU chip is greater than or equal to the maximum number threshold value, but the ARM chip fails to enter the recovery mode, it is determined that the sending fails, and the automatic burning process is terminated (i.e., the preset program burning stop condition is met). In this way, the situation where the recovery mode fails to enter due to accidental factors can be avoided, and it is ensured that the ARM chip stably enters the recovery mode.

[0077] Step S10023, judging whether the current chip domain to be burned enters the recovery mode according to the USB device information;

[0078] According to the manufacturer ID (identity mark) and device ID in the USB device information, it can be determined whether the ARM chip in the same chip domain is in recovery mode.

[0079] For example, a USB device may be an ADCU (Autonomous Driving Control Unit) device, and the manufacturer ID and device ID of the ADCU are 9307 and 7305. Execute the "lsusb" command on the program burning system, and search for information containing 9307 or 7305 from the USB device information returned to the vehicle program burning system. Based on this, it can be identified whether the ADCU device is included in all USB devices. If included, it means that the ADCU has entered the recovery mode.

[0080] Step S10024: If yes, determine the location of the burning program file according to the single-domain burning function, and burn the program file at the location of the burning program file into the ARM chip corresponding to the current chip domain to be burned.

[0081] It should be noted that the location of the burning program file can be the path used to search for the corresponding program file. For example, the statement in the single-domain burning function can be written as ". / flash.sh path / to / burn_file a", where "flash.sh" is the single-domain burning function that needs to be called in the above steps, and the single-domain burning function is set with parameters indicating the location of the burning program file; "path / to / burn" is used to specify the program file path, and "a" indicates the chip domain identifier corresponding to the ARM that needs to be burned; for example, there are two chip domains marked as "a" and "b" that need to be burned, which means that the current chip domain to be burned is the "a" domain, and the program file at the location of the burning program file needs to be burned in the ARM chip corresponding to the "a" domain.

[0082] In another feasible implementation, the step of calling a preset single-domain burning function according to the program burning script, and controlling the current chip domain to be burned to execute the corresponding target program burning task based on the single-domain burning function, after step S1002, may include:

[0083] After the target program burning task is successfully executed, a preset exit recovery instruction is sent to the current chip domain to be burned, so as to control the current chip domain to be burned to exit the recovery mode.

[0084] It should be noted that the exit recovery instruction is set by the chip supplier of the vehicle-mounted SOC system, such as the "pmstateset" instruction. After exiting the recovery mode, the current chip domain to be burned will enter the working state, and the vehicle-mounted program burning system will enter the working state. At this time, the "lsusb" instruction is executed again by the vehicle-mounted program burning system to obtain new USB device information. In the new USB device information, if the manufacturer ID and device ID of the USB device corresponding to the current chip domain to be burned cannot be detected, it means that the ARM chip in the current chip domain to be burned has successfully exited the recovery mode, that is, the current chip domain to be burned has successfully exited the recovery mode.

[0085] In this embodiment, according to the program burning script, the burning port switching function is called to determine the current chip domain to be burned from the chip domain queue to be burned; according to the program burning script, the preset single domain burning function is called, and based on the single domain burning function, the current chip domain to be burned is controlled to execute the corresponding target program burning task; when the program burning task corresponding to the current chip domain to be burned is successfully executed, the burning port switching function is called to determine the new current chip domain to be burned, and the step of calling the preset single domain burning function according to the program burning script to control the current chip domain to be burned to execute the corresponding target program burning task is returned until the preset program burning stop condition is met. The scheme proposed in this embodiment is provided with automatic switching of the chip domain that needs to be burned, which can completely avoid the intervention of artificial switching of the hardware interface, and does not require artificial intervention of the ARM chip and MCU chip in the vehicle-mounted SOC system, which simplifies the process of vehicle-mounted program burning, and can improve the efficiency of vehicle-mounted program burning while ensuring the accuracy of vehicle-mounted program burning.

[0086] It should be noted that the above embodiments can be reasonably combined and implemented according to actual conditions, and this embodiment will not be described in detail.
