[0050] As automotive functions become more diverse, intelligent, and safer, vehicle systems are becoming more and more complex, and the demand for vehicle-grade system chips such as SOC (System on Chip) is increasing. In order to enable fast and reliable startup of SOC, SOC is generally designed to use NOR Flash (or non-flash memory) as the startup code and store the operating system and application programs in eMMC (embedded multimedia card), so NOR Flash and eMMC need to be burned into SOC.

[0051] Traditional SOCs are usually connected to computers via USB or serial ports for burning. Since the theoretical bandwidth of USB is only 480Mbps, the transmission speed is about 60MB / s, and the bandwidth of the serial port is even lower, it is not suitable for transmitting large files. At the same time, in order to meet the reliability requirements of automotive-grade system chips, the system and application should design two areas, A and B, for partition startup to ensure that the system can start normally at any time. Therefore, the system firmware will be larger than that of ordinary systems, resulting in a significant increase in the firmware burning time of automotive-grade system chips, which is too long and inefficient. In actual applications, the total size of the firmware of NOR Flash and eMMC is 60GB, and it takes about 40 minutes to burn it for a dual-chip SOC, which is a long time.

[0052] This application uses a step-by-step boot to build an operating system into a vehicle-mounted system chip. The operating system can be connected to the burning device through Ethernet communication, and the Ethernet's function of quickly transmitting image files can be used to greatly improve the burning speed, thereby solving the problem of slow burning speed caused by low USB or serial port image file transmission speed.

[0053] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] In a first aspect, the present disclosure provides Figure 1 The method for burning a vehicle-mounted system chip shown includes the following steps:

[0055] S101, initializing the memory;

[0056] Among them, initializing the memory refers to a series of preparation operations for the memory after the computer system is powered on or reset, so that the memory can be used correctly and safely to store data and program instructions. Initializing the memory is mainly used to clear uncertain data and configure memory parameters. The memory is a volatile storage device and the data is lost after power failure. When the system restarts, the data in the memory may be the remnants of the last use. These data may be disorganized and unpredictable for the new system operation. Initialization can set the memory unit to a known initial state, such as all 0 or all 1, to prevent old data from interfering with the operation of the new program. Memory initialization also includes configuring the physical and logical parameters of the memory. This involves the operating frequency, timing parameters, etc. of the memory. Correct parameter configuration can ensure efficient and stable communication between the memory and the SOC and other system components.

[0057] In one embodiment, memory mainly refers to random access memory, which is a type of computer memory. It allows data reading and writing operations to be completed in almost the same time, regardless of the physical location of the data storage. The SOC can directly and quickly access any storage unit in the memory.

[0058] S102, receiving a second boot program firmware with an Ethernet controller, and starting the second boot program, wherein the Ethernet controller is used to implement information transmission through Ethernet;

[0059] In one embodiment, the SOC establishes a connection with the burning device through a serial port, and the burning device sends the second boot program firmware with the Ethernet controller to the memory of the SOC.

[0060] The burning device is used to store the system firmware required for the burning process and output it to the SOC. The burning device may be a computer, a burner or a controller with an output function.

[0061] The SOC and the burning device are transmitted through the Xmodem protocol, which is a file transfer protocol used in data communication. It is used to transmit data through serial communication lines in an asynchronous communication environment. The Xmodem protocol can ensure that data is accurately transmitted from the sender to the receiver in an environment with relatively low communication reliability.

[0062] In one embodiment, the second boot program firmware is uboot (Universal Boot Loader) firmware, which is used to load the system kernel and boot the system.

[0063] The second boot program configures the Ethernet controller and implements the network communication function through the protocol stack in the second boot program, which facilitates the subsequent transmission of large files.

[0065] In one embodiment, the SOC is connected to the burning device via Ethernet, the burning device transmits the operating system to the memory of the SOC via Ethernet, and boots the operating system through the second boot program.

[0066] Among them, different Ethernet bandwidths can be selected according to different transmission speeds, such as 10Mbps, 100Mbps, 1000Mbps, and 10Gbps. The higher the bandwidth, the faster the transmission speed.

[0067] In one embodiment, the operating system is the Linux kernel.

[0069] In one embodiment, the burning device transmits the image file to the SOC via Ethernet, the SOC receives the image file transmitted by the computer, the operating system loads the image file, and burns the image file; wherein the operating system implements simultaneous burning of multiple image files through multiple processes.

[0070] The image file is a file copy containing the complete EMMC and NOR flash contents, and is used to accurately copy the data therein to the SOC.

[0071] In the operating system, a process is an instance of a running program. Each process has its own independent address space, program counter, stack and other resources. The Linux system allows the system to run multiple tasks at the same time, and these processes can be executed concurrently. Using the multi-process operation of the Linux system, EMMC and NOR flash can be burned at the same time, further improving the burning speed.

The SBL program finds the starting address of the uboot program stored in the DDR memory, jumps the execution process to the entry address of the uboot program, reads the code of the uboot program from the DDR memory and executes it, and starts the uboot program.

[0099] The burning device and SOC establish an Ethernet connection through the Ethernet controller. The SOC receives the simplified Linux kernel input from the burning device through Ethernet.

[0100] In one embodiment, different Ethernet bandwidths may be selected according to different transmission speeds, such as 10 Mbps, 100 Mbps, 1000 Mbps, and 10 Gbps. The higher the bandwidth, the faster the transmission speed.
