[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 solutions of the present application, the following will be described in detail combined with the accompanying drawings and specific embodiments.

[0040] The main solution of the embodiment of the present application is: according to the preset program burning script, the corresponding program burning task is executed in the chip domain in turn.

[0041] At present, the vehicle-mounted SOC is usually burned by using the artificial burning method. However, the artificial burning method needs a large amount of manual switching of the chip domain to be burned, and the process is tedious and easy to make mistakes, which may cause the occurrence of production accidents.

[0042] Based on the scheme, the vehicle program burning process is simplified by pre-setting the program burning script, so as to reduce manual intervention; the program burning script is used to control the chip domains one by one to perform the corresponding program burning task, so as to realize automatic switching of each chip domain and complete the program burning task, thereby ensuring the accuracy of the vehicle program burning while improving the efficiency of the vehicle program burning.

[0043] It should be noted that the execution subject of the 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, a vehicle program burning system, etc. capable of realizing the above functions. The vehicle program burning system is taken as an example to describe the embodiment and the following embodiments.

[0044] Based on this, the embodiment provides a vehicle program burning method, which is described with reference to Figure 1 , Figure 1 is a flowchart of the first embodiment of the vehicle program burning method.

[0045] In the embodiment, the vehicle program burning method is applied to a vehicle SOC, a vehicle SOC and a vehicle program burning system establish a communication connection, and the vehicle program burning method includes the step S100:

[0046] Step S100, according to the pre-set program burning script, the chip domains are controlled one by one to perform the corresponding program burning task.

[0047] It should be noted that the vehicle program burning method proposed in the application is applied to the scene of program burning of vehicle SOC in intelligent driving. The existing intelligent driving hardware usually uses SOC containing ARM chip and MCU chip, wherein the ARM chip can contain GPU (Graphic Processing Unit, graphic processor) and is used to process large computing power scenes such as image acquisition and processing; the MCU chip uses real-time operating system or no operating system to process functions such as vehicle regulations and safety that need fast response. In order to increase the computing power of SOC, the commonly used intelligent driving SOC contains double chip domains.

[0048] The vehicle SOC with the above architecture can meet the requirements of vehicle large computing power and fast response at the same time, but it also makes the burning of SOC program more complicated. Referring to Figure 2 , Figure 2 is a schematic diagram of manual burning process of vehicle program; as Figure 2As shown, at present, the method commonly used by the industry for the burning of 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 (for example, the recovery mode), and then manually confirm success before burning the ARM end. If the vehicle-mounted SOC system contains multiple sets of ARM chip and MCU chip structures (a combination of an ARM chip and an MCU chip is usually referred to as a chip domain), it is also necessary to take the above-mentioned step for each domain respectively, and it is necessary to manually switch to the burning interface of another chip domain after the burning of a chip domain is completed, 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 is, the lower the efficiency of the current burning method will be, and because a large amount of manual switching work is involved, the chance of error will also be higher.

[0049] Based on the above considerations, the present application proposes a method for burning an intelligent driving vehicle-mounted SOC through a preset program burning script. Referring to Figure 3 , Figure 3 A simple process diagram for burning based on a program burning script is proposed for the embodiments of the present application; as Figure 3 shown, the scheme proposed in the present application can achieve one-key execution of program burning, and completely does not require manual switching of hardware interfaces during the burning process, nor does it require separate operation of the ARM and MCU of each chip domain in the vehicle-mounted SOC, simplifying the burning process of the intelligent driving SOC, improving the burning efficiency, and reducing the error rate.

[0050] In addition, it should be noted that before the vehicle-mounted program burning system burns the vehicle-mounted SOC, it is necessary to determine that the vehicle-mounted SOC meets the preset hardware burning conditions. The hardware burning conditions are as follows: a vehicle-mounted SOC for burning needs to be prepared, 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 vehicle-mounted program burning system is powered on, and at the same time, the vehicle-mounted SOC is powered on; the version of the computer carried by the vehicle-mounted program burning system can select the operating system Linux 5.0 or above version. Among them, the computer version model is not specifically limited in the present embodiment, but the computer version model needs to support the running of the program burning script in the actual implementation process; it is also necessary to prepare sufficient connection cables, including MCU communication cables and ARM communication cables, and the number of connection cables needs to be doubled for each additional chip domain in the vehicle-mounted SOC. In addition, before the execution of the program burning script, the MCU communication cable and the ARM communication cable need to be connected to the vehicle-mounted SOC and the computer.

[0051] Further, the preset program burning script includes a command transmission function, which is used to perform serial port read-write operations on the MCU chip and the ARM chip of each of the plurality of chip domains.

[0052] It should be noted that the command transmission function can be constructed by a command line environment based on a Bash command, where Bash is a Shell (command line environment) of a Linux system. The read and write of the serial port are directly implemented by using the bash command, without the need to additionally install library files, with low requirements for the system and good compatibility. The serial port read and write operation can include sending sleep, wake-up, reading SOC state and the like.

[0053] Based on this, the program burning script can process the functions of serial communication and recovery result identification based on the Bash script, where the function of processing serial communication can include stably sending a recovery command to the MCU, and the recovery is used to identify whether the ARM chip enters the recovery mode, so that the program burning script starts to perform the program burning task only in the case that the ARM chip enters the recovery mode.

[0054] In this embodiment, the plurality of chip domains are sequentially controlled according to the preset program burning script to perform corresponding program burning tasks. The program burning script is used to simplify the vehicle program burning process, thereby reducing manual intervention. The plurality of chip domains are sequentially controlled by the program burning script to perform corresponding program burning tasks, so that automatic switching of each chip domain can be realized, and the program burning task can be completed, thereby the vehicle program burning efficiency can be improved while ensuring the accuracy of the vehicle program burning.

[0055] In a feasible embodiment, before the step of sequentially controlling the plurality of chip domains according to the preset program burning script to perform corresponding program burning tasks, the steps S10-S20 can be included.

[0056] In step S10, a chip domain queue to be burned is acquired.

[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 for storing the chip domain to be burned can be a queue, and each element in the queue represents a chip domain and contains the related information of the chip domain.

[0058] In step S20, a burning port switching function is set according to the device identifier corresponding to each chip domain in the chip domain queue to be burned, and the burning port switching function is used to switch the chip domain according to the device identifier.

[0059] Specifically, the chip domain queue 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 embodiment, a chip domain queue to be burned is obtained; a burning port switching function is set according to a device identifier corresponding to each chip domain in the chip domain queue to be burned, and the burning port switching function is used to switch the chip domain according to the device identifier. In this embodiment, the burning port switching function is set to realize automatic switching of the burning port. In the case where multiple chip domains need to be burned, manual intervention can be effectively avoided, the accuracy of the vehicle program burning is ensured, and the efficiency of the vehicle program burning is improved.

[0061] Based on the first embodiment of the present application, the same or similar contents as the above-mentioned first embodiment can be referred to the above description, and will not be described hereinafter. On this basis, please refer to Figure 4 , Figure 4 The flowchart of the second embodiment of the vehicle program burning method of the present application is shown in FIG. 10. As shown in FIG. 10, the step S100 of sequentially controlling the plurality of chip domains according to the preset program burning script to execute the corresponding program burning task can include steps S1001-S1004. Figure 4

[0062] In step S1001, the burning port switching function is called 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 the program burning script is set, the current instruction and configuration parameter to be executed need to be read from the program burning script. According to the program burning script, the previously set burning port switching function is called. 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 identifier.

[0064] In step S1002, a preset single-domain burning function is called according to the program burning script, and the current chip domain to be burned is controlled to execute the corresponding target program burning task based on the single-domain burning function.

[0065] In this embodiment, the preset single-domain burning function is called using the current chip domain to be burned determined in step S1001. The single-domain burning function controls the hardware device to execute the target program burning task of the current chip domain to be burned according to the preset burning parameters and steps. It should be noted that the progress and state of the burning process need to be monitored to ensure that the burning process proceeds normally.

[0066] ​Step S1003, in the case that 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 returning to execute a preset single-domain burning function according to the program burning script to control the current chip domain to be burned to execute a corresponding target program burning task is returned until a preset program burning stop condition is met.

[0067] After the burning task of the current chip domain to be burned is completed, the burning result is checked to determine whether it is successful. More specifically, the state or return information of the device can be read to determine whether the current burning task is successful. If the current burning task is successful, the burning port switching function is called again to determine the next chip domain to be burned. At the same time, the step S1002 is returned to call the single-domain burning function according to the information of the new current chip domain to be burned and execute a corresponding burning task. The steps S1002 and S1003 are repeated until a preset program burning stop condition is met.

[0068] It should be noted that the program burning stop condition can include that all chip domains have been burned, a maximum burning time limit is reached, an error occurs, and the like.

[0069] Step S1004, a program burning result is obtained.

[0070] It should be noted that the program burning result can be a domain name of all chip domains whose program burning is completed or a time consumption of completing the program burning, which is used as a basis for judging the efficiency of the program burning.

[0071] In a feasible implementation, the step S1002 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 a corresponding program burning task based on the single-domain burning function can include steps S10021-S10024:

[0072] Step S10021, a preset single-domain burning function is called according to the program burning script, and a resume instruction is sent to a micro control unit (MCU) chip corresponding to the current chip domain to be burned based on the single-domain burning function to control an advanced reduced instruction set computing (ARM) chip corresponding to the current chip domain to be burned to enter a resume mode.

[0073] Exemplarily, the program burning system sends a recovery instruction (for example, a recovery instruction) to the serial port of the MCU chip to enter the recovery mode, assuming that the serial port identifiers of the MCU chip are ttyACM1 and ttyACM3 in the default state, and assuming that the chip domains that need to be burned are the A domain and the B domain. When burning the A domain, the recovery instruction is sent to ttyACM1; when burning the B domain, the recovery instruction is sent to ttyACM3. It should be noted that, in order to prevent the default port from being occupied, no other serial port device can be installed on the burning computer.

[0074] In step S10022, a recovery mode confirmation instruction is executed to obtain serial port interface bus USB device information;

[0075] After sending the recovery instruction to the serial port of the MCU chip, it is necessary to identify whether the ARM chip of the same chip domain enters the recovery mode. It should be noted that the program burning script can only be executed on the device that enters the recovery mode. After the recovery instruction is sent, the corresponding chip domain enters the recovery mode, but there is a certain probability that the recovery mode entry fails. Therefore, before burning the current chip domain to be burned, it is necessary to confirm whether the corresponding domain is in the recovery mode. The “lsusb” instruction is executed on the vehicle program burning system, which is used to display USB related information and will obtain USB device information of all USB devices. The USB device refers to all external devices connected to the vehicle program burning system through the serial port interface bus. In the scenario of burning the vehicle SOC system, the USB device is generally a controller device carrying the vehicle SOC system (including a chip domain composed of an MCU chip and an ARM chip), such as a power domain controller, a chassis domain controller, and the like.

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

[0077] In step S10023, whether the current chip domain to be burned enters the recovery mode is judged according to the USB device information.

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

[0079] For example, a USB device, specifically, an ADCU (Autonomous Driving Control Unit) device, and the vendor ID and the device ID of the ADCU are 9307 and 7305 respectively. The "lsusb" instruction is executed on the program burning system, and the information containing 9307 or 7305 is searched from the USB device information returned to the vehicle-mounted program burning system, according to which it can be identified whether the ADCU device is contained in all USB devices, if yes, it indicates that the ADCU enters the recovery mode.

[0080] If yes, in step S10024, the program file position of the burning program file is determined according to the single-domain burning function, and the program file at the program file position of the burning program file is burned in the ARM chip corresponding to the current chip domain to be burned.

[0081] It should be noted that the program file position of the burning program file can be a path for searching 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", wherein "flash.sh" is the single-domain burning function to be called in the above step, and the single-domain burning function is provided with a parameter indicating the program file position of the burning program file; "path / to / burn" is used to specify the program file path, and "a" indicates the chip domain identification corresponding to the ARM to be burned; for example, there are two chip domains marked as "a" and "b" to be burned, which indicates that the current chip domain to be burned is "a" domain, and the program file at the program file position of the burning program file is burned in the ARM chip corresponding to the "a" domain.

[0082] In another possible implementation, after step S1002, the single-domain burning function preset according to the program burning script is called, and the current chip domain to be burned is controlled to execute the corresponding target program burning task based on the single-domain burning function.

[0083] After the target program burning task is executed successfully, 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 SOC system, for example, a "pmstate set" instruction. After exiting the recovery mode, the current chip domain to be programmed will enter a working state, and the vehicle program programming system will enter a working state. At this time, the "lsusb" instruction is executed again through the vehicle program programming system to obtain new USB device information. In the new USB device information, if the manufacturer ID and the device ID of the USB device corresponding to the current chip domain to be programmed cannot be detected, it indicates that the ARM chip in the current chip domain to be programmed successfully exits the recovery mode, that is, the current chip domain to be programmed successfully exits the recovery mode.

[0085] In the embodiment, according to the program programming script, the programming port switching function is called to determine the current chip domain to be programmed from the chip domain queue to be programmed; the preset single-domain programming function is called according to the program programming script, and the current chip domain to be programmed is controlled to execute the corresponding target program programming task based on the single-domain programming function; in the case that the program programming task corresponding to the current chip domain to be programmed is successfully executed, the programming port switching function is called to determine a new current chip domain to be programmed, and the step of executing the preset single-domain programming function according to the program programming script to control the current chip domain to be programmed to execute the corresponding target program programming task is returned until the preset program programming stop condition is met. The scheme in the embodiment automatically switches the chip domains to be programmed, can completely avoid the intervention of manual switching of hardware interfaces, does not need manual intervention of the ARM chip and the MCU chip in the vehicle SOC system, simplifies the process of vehicle program programming, and can improve the efficiency of vehicle program programming while ensuring the accuracy of vehicle program programming.

[0086] It should be noted that the above embodiments can be reasonably combined according to actual conditions, and the embodiment will not be repeated here.
