[0036] Taking the in-vehicle switching device as an example, the ability of the in-vehicle switching device to collect information quickly and reliably is a key factor in ensuring the efficient operation and safe communication of the vehicle, which requires the in-vehicle switching device to be able to start quickly. The startup process of the traditional in-vehicle switching device is as follows:

[0037] Power on and perform self-check on the hardware; start the CPU; the uboot starts to establish an appropriate system software and hardware environment, and boot the linux operating system to load. During this process, peripherals such as the memory and flash memory (subsequently referred to as flash memory 1) of the in-vehicle switching device are initialized; the CPU loads the configuration information of the switching chip (such as the routing table, MAC table, etc.) in the flash memory 1, converts the configuration information format into a driver structure configuration file (named configfile file), and then writes the driver structure configuration file into the registers of the switching chip to complete the configuration of the switching chip. In this way, the startup of the in-vehicle switching device is completed, and the switching chip can subsequently forward network data normally.

[0038] The entire startup process of the above-mentioned in-vehicle switching device usually takes more than 40 seconds, which will affect the vehicle's handling feel and driving experience.

[0039] To solve the above problems, the embodiments of the present application provide a method for starting a switching device. By quickly configuring the switching chip through a microcontroller unit (MCU), the switching chip starts to work when powered on, combined with the normal CPU startup program of the switching device without interruption, greatly shortening the startup working time of the switching chip and ensuring the communication timeliness of the switching device. The method for starting the switching device in the embodiments of the present application will be introduced in detail below with reference to the accompanying drawings.

[0040] See Figure 1 , Figure 1Schematic flowchart of a startup method for a switching device provided by an embodiment of this application. The switching device includes a CPU and a switching chip, and the microcontroller is connected to the switching chip. Specifically, the microcontroller can be connected to the switching chip through a Serial Peripheral Interface (SPI). As Figure 1 shown, a startup method for a switching device provided by an embodiment of this application may include the following steps S101 to S102, and these steps will be described in detail below.

[0041] S101, when the switching device and the microcontroller are powered on simultaneously, control the CPU to close the write channel to the switching chip.

[0042] Specifically, in an embodiment of this application, when the switching device and the microcontroller are powered on and started simultaneously, the CPU can be controlled to close the write channel to the switching chip. This write channel is the channel for writing to the switching chip after the CPU converts the configuration information in Flash 1 into a driver configuration file.

[0043] Continuing to take the in-vehicle switching device as an example, after closing the write channel of the CPU to the switching chip, the startup process of the in-vehicle switching device is as follows: power on and perform self-check on the hardware when starting up; start the CPU; start uboot to boot and load the linux operating system to initialize peripherals such as the memory and Flash 1 of the in-vehicle switching device; the CPU loads the configuration information of the switching chip from Flash 1, converts the configuration information format into a driver structure configuration file, but does not write the driver structure configuration file into the registers of the switching chip.

[0044] S102, control the microcontroller to write the driver structure configuration file into the switching chip so that the switching chip can perform data forwarding; where the driver structure configuration file is pre-stored in the microcontroller.

[0045] Specifically, in an embodiment of this application, the driver structure configuration file obtained by converting the configuration of the switching chip is pre-stored in the microcontroller, and the driver structure configuration file contains the address and write value entries of the switching chip. For this reason, after the microcontroller is powered on, the microcontroller can be controlled to write the driver structure configuration file into the registers of the switching chip, thereby realizing the configuration of the switching chip by the microcontroller.

[0046] In a possible implementation, for a switching device with complex switching functions, its configuration is relatively complex. Therefore, the driver structure configuration file can be written into Flash 2 of the microcontroller by the CPU through a traditional switching device startup process. For this reason, a startup method for a switching device provided by an embodiment of this application, where the method of pre-storing the driver structure configuration file in the microcontroller may include the following steps, and these steps will be described in detail below.

[0047] When the switching device is powered on, the control CPU writes the driver structure configuration file into the flash memory of the microcontroller.

[0048] In the embodiments of the present application, the startup of the switching device can be divided into a preliminary preparation stage and a formal startup stage.

[0049] Continuing with the in-vehicle switching device as an example, in the preliminary preparation stage, the switching device performs the traditional startup process, including: power-on self-test of the hardware when starting up; CPU startup; uboot startup to boot the linux operating system for loading to initialize peripherals such as the memory and flash memory 1 of the in-vehicle switching device; the CPU loads the configuration information of the switching chip in the flash memory 1, converts the format of the configuration information into a driver structure configuration file, and writes the driver structure configuration file into the registers of the switching chip to complete the configuration of the switching chip. And, after the CPU converts the configuration information into a driver structure configuration file, it can control the CPU to write the driver structure configuration file into the flash memory 2 of the microcontroller. Specifically, the CPU can establish a communication connection with the microcontroller through the UART interface (the full English name is Universal Asynchronous Receiver / Transmitter, a commonly used serial communication interface). In this regard, the CPU can write the driver structure file into the flash memory 2 through the UART interface.

[0050] In the formal startup stage, the switching device and the microcontroller are powered on simultaneously. On the side of the switching device, after closing the write channel of the CPU to the switching chip, the startup process of the in-vehicle switching device is as follows: power-on self-test of the hardware when starting up; CPU startup; uboot startup to boot the linux operating system for loading to initialize peripherals such as the memory and flash memory 1 of the in-vehicle switching device; the CPU loads the configuration information of the switching chip from the flash memory 1, converts the format of the configuration information into a driver structure configuration file, but does not write the driver structure configuration file into the registers of the switching chip to avoid port disconnection caused by reconfiguration. On the side of the microcontroller, the driver structure configuration file stored in its flash memory 2 is written into the registers of the switching chip through the serial peripheral interface to complete the configuration of the switching chip. After the switching chip is configured, the switching chip can implement port up / down according to the configuration and forward network data according to the MAC table and routing table, etc. This can quickly start the switching chip through the microcontroller without affecting the normal startup of the switching device, so that the switching chip can work quickly after being powered on, greatly shortening the startup working time of the switching chip.

[0051] In a possible implementation, the microcontroller establishes a connection with the switching chip through the Serial Peripheral Interface, and can adjust the clock frequency of the Serial Peripheral Interface to achieve high-speed configuration, so as to complete the configuration within a few seconds. In this regard, a method for starting a switching device provided by an embodiment of the present application further includes the following steps:

[0052] Adjust the clock frequency of the Serial Peripheral Interface to adjust the writing time of the microcontroller to the switching chip.

[0053] Specifically, in the embodiment of the present application, the clock frequency of the Serial Peripheral Interface can be adjusted according to the actual scenario, so as to shorten the writing time for the microcontroller to write the drive structure configuration file into the switching chip.

[0054] In a possible implementation, after some switching devices are started, the CPU may still configure other functions for the switching chip, such as dynamic routing and setting the port status according to the STP protocol. The write channel of the CPU to the switching chip can be opened after the switching device is started successfully. Refer to Figure 2 , Figure 2 which is another schematic flowchart of a method for starting a switching device provided by an embodiment of the present application. As Figure 2 shown, a method for starting a switching device provided by an embodiment of the present application further includes the following step S103, and the following is a detailed description of this step.

[0055] S103, after the switching device is started successfully, open the write channel.

[0056] Specifically, in the embodiment of the present application, since the startup items of the microcontroller are fewer than those of the CPU, the microcontroller can complete the configuration of the switching chip before the switching device is started successfully, so as to realize the normal data forwarding of the switching chip. Moreover, the sign that the switching device is started successfully is that the CPU loads the configuration information of the switching chip from Flash 1 and converts it into a drive structure configuration file. In this regard, the write channel of the CPU to the switching chip can be opened after the switching device is started successfully, which does not affect the configuration of other functions of the CPU to the switching chip after the switching device is started successfully.

[0057] Through the above description, a method for starting a switching device provided by an embodiment of the present application can store the driver structure configuration file of the switching chip in the flash memory of the single-chip microcomputer in advance by the CPU writing the driver configuration file through a traditional switching device startup process. When the switching device and the single-chip microcomputer are powered on simultaneously, the write channel of the CPU to the switching chip is closed; on the switching device side, it performs a normal startup process but cannot write the driver configuration file to the registers of the switching chip; on the single-chip microcomputer side, it can write the driver configuration file in its flash memory to the registers of the single-chip microcomputer, thereby completing the configuration of the switching chip so that the switching chip can perform normal data forwarding work. Since the single-chip microcomputer has fewer startup items than the CPU, when the switching device and the single-chip microcomputer start up simultaneously, the configuration of the switching chip can be completed faster, greatly shortening the startup working time of the switching chip and ensuring the communication timeliness of the switching device.

[0058] Moreover, the present application can open the write channel of the CPU to the switching chip again after the switching device starts up successfully, so that the CPU can perform other function configurations on the switching chip.

[0059] In addition, the single-chip microcomputer can establish a connection with the switching chip through the Serial Peripheral Interface (SPI). The present application can adjust the writing time of the single-chip microcomputer to the switching chip by adjusting the clock frequency of the Serial Peripheral Interface, and shorten the time for the single-chip microcomputer to write the driver structure configuration file to the switching chip within a few seconds.

[0060] Continuing to take the in-vehicle switching device as an example, in the preliminary preparation stage, the switching device performs a traditional startup process, including: power-on self-check of hardware at startup; CPU startup; uboot startup to boot the Linux operating system for loading to initialize peripherals such as the memory and flash memory 1 of the in-vehicle switching device; the CPU loads the configuration information of the switching chip in the flash memory 1, converts the configuration information format into a driver structure configuration file, and while writing the driver structure configuration file into the switching chip, can write the driver structure configuration file to the flash memory 2 of the single-chip microcomputer through the UART interface.

[0061] In the formal startup phase, the switching device and the microcontroller are powered on simultaneously. On the side of the switching device, after the CPU closes the write channel to the switching chip, the startup process of the in-vehicle switching device is as follows: power on and perform self-check on the hardware; start the CPU; start uboot to boot and load the Linux operating system to initialize peripherals such as the memory and flash 1 of the in-vehicle switching device; the CPU loads the configuration information of the switching chip from flash 1, converts the configuration information format into a driver structure configuration file, but does not write the driver structure configuration file into the registers of the switching chip. On the side of the microcontroller, the driver structure configuration file stored in flash 2 is written into the registers of the switching chip through the Serial Peripheral Interface (SPI), thereby completing the configuration of the switching chip. By adjusting the clock frequency of the SPI, the writing time is shortened to within a few seconds.

[0062] After the microcontroller completes the configuration of the switching chip, the switching chip can set the configuration ports up / down and forward network data according to the MAC table, routing table, etc. This enables the switching chip to be quickly started by the microcontroller without affecting the normal startup of the switching device, allowing the switching chip to start working quickly after power-on and greatly shortening the startup time of the switching chip.

[0063] After the switching device starts up successfully, open the write channel of the CPU to the switching chip, which does not affect other functional configurations of the CPU to the switching chip after the switching device starts up successfully.

[0064] In summary, in this application, the switching device can be started according to the normal process. After closing the write channel of the CPU to the switching chip, the CPU cannot configure the switching chip. Moreover, when the switching device starts up, the microcontroller starts up and directly configures the switching chip. Since the microcontroller has fewer startup items than the CPU, the startup time of the switching chip can be greatly shortened, ensuring the communication efficiency of the switching device. By quickly configuring the switching chip by the microcontroller, the switching chip starts working after power-on. Then, combined with the normal CPU startup program of the switching device without interruption, the startup time of the traditional switching chip is greatly shortened.

[0065] The above introduces a startup method for a switching device provided by an embodiment of this application. The following will introduce the device for executing the above startup method of the switching device.

[0066] See Figure 3 , Figure 3 which is a schematic structural diagram of a startup device for a switching device provided by an embodiment of this application. As Figure 3 shown, a startup device for a switching device provided by an embodiment of this application includes:

[0067] A file storage module 301, which is used to pre-store a driver structure configuration file in the microcontroller.

[0068] A channel control module 302, configured to control the CPU to close the write channel to the switching chip when the switching device and the single-chip microcomputer are powered on simultaneously.

[0069] A chip writing module 303, configured to control the single-chip microcomputer to write a driver structure configuration file into the switching chip, so that the switching chip can perform data forwarding; wherein, the driver structure configuration file is pre-stored in the single-chip microcomputer.

[0070] In a possible implementation, the file storage module 301 is specifically configured to:

[0071] When the switching device is powered on, control the CPU to write the driver structure configuration file into the flash memory of the single-chip microcomputer.

[0072] In a possible implementation, the single-chip microcomputer establishes a connection with the switching chip through a serial peripheral interface. The chip writing module 303 is further configured to:

[0073] Adjust the clock frequency of the serial peripheral interface to adjust the writing time of the single-chip microcomputer to the switching chip.

[0074] In a possible implementation, the channel control module 302 is further configured to:

[0075] After the switching device starts up successfully, open the write channel.

[0076] It should be noted that for the refined functions of each module in the embodiments of the present application, reference can be made to the corresponding disclosed parts in the embodiments of the startup method of the above switching device, which will not be elaborated here.

[0077] Through the above description, for a startup device of a switching device provided in the embodiments of the present application, the file storage module can pre-store the driver structure configuration file of the switching chip in the flash memory of the single-chip microcomputer by the way that the CPU writes the driver configuration file through a traditional switching device startup process. When the switching device and the single-chip microcomputer are powered on simultaneously, the channel control module closes the write channel of the CPU to the switching chip; on the side of the switching device, it performs a normal startup process, but cannot write the driver configuration file to the registers of the switching chip; on the side of the single-chip microcomputer, the chip writing module can write the driver configuration file in its flash memory into the registers of the single-chip microcomputer, thereby completing the configuration of the switching chip, so that the switching chip can normally perform data forwarding work. And because the single-chip microcomputer has fewer startup items than the CPU, when the switching device and the single-chip microcomputer start at the same time, the configuration of the switching chip can be completed faster, greatly shortening the startup working time of the switching chip and ensuring the communication timeliness of the switching device.

[0078] Moreover, after the switching device completes startup, the channel control module re-opens the write channel of the CPU to the switching chip, enabling the CPU to perform other functional configurations on the switching chip.

[0079] In addition, the microcontroller can establish a connection with the switching chip through the Serial Peripheral Interface (SPI). The chip writing module can adjust the writing time of the microcontroller to the switching chip by adjusting the clock frequency of the Serial Peripheral Interface, shortening the time for the microcontroller to write the drive structure configuration file to the switching chip within a few seconds.
