Description

Multi-peripheral mirror image burning system Technical Field The invention relates to the technical field of embedded system development and production manufacturing, in particular to a multi-peripheral mirror image burning system, and especially relates to a system for carrying out system mirror image batch burning on an embedded core board or module. The invention specifically belongs to the technical field of intersection of computer hardware and an embedded system, and relates to multi-host parallel control, distributed computing, industrial automatic production equipment and an embedded software deployment method. The system is particularly suitable for industrial scenes requiring large-scale and high-efficiency burning of an operating system or firmware mirror image, such as equipment manufacturing of the Internet of things, intelligent hardware production lines, batch programming of embedded controllers and the like. Background The raspberry group calculation Module 4 (CM 4 for short) is an embedded core board for industrial and commercial applications, introduced by the raspberry group foundation. The device integrates core components such as a CPU, an LPDDR4 memory, an eMMC flash memory, a wireless module and the like in a physical structure, and leads out a plurality of high-speed and general-purpose interfaces such as PCIe, gigabit Ethernet, camera CSI, a display interface DSI, HDMI2.0, USB2.0, GPIO and the like through two high-speed connectors. Because of its powerful performance and rich interfaces, CM4 is widely used in various embedded products such as internet of things gateways, industrial controllers, intelligent display devices, network devices, and the like. In the CM4 production or development process, the eMMC flash memory (as a main storage medium) needs to be pre-burned with a corresponding Linux software system or other customized operating systems. The core principle of burning CM4 is to put it into a special "USB mass storage device" mode (similar to the swipe mode of a cell phone). In this mode, the eMMC storage space of CM4 may be recognized by another computer (often referred to as a "host") as a generic mass storage device (e.g., a USB disk) through its on-board USB2.0 interface. The host can then write the precompiled system image file to this identified "U disk" using a special burn tool (e.g., dd command, rpi-imager, or other image writing software) to complete the system installation. Currently, the most common burning scheme uses a separate computer as the host. The host can be a personal computer running Windows operating system or another raspberry group 4B microcomputer. The use of a Windows computer for burning is an intuitive method by which a user can operate under a graphical interface. However, the use of raspberry group 4B microcomputers as hosts has significant advantages. First, the cost of raspberry group 4B is far lower than that of a complete Windows computer, and has extremely high economical efficiency. Secondly, raspberry group 4B is small in size, which is beneficial to constructing a compact burning environment. Furthermore, the native Linux operating system runs and is naturally compatible with the CM4 burning environment, so that the trouble of installing specific drivers and cross-platform tools on the Windows system is eliminated, and the burning environment is more rapidly and stably deployed. However, the existing burning scheme has a remarkable defect of low efficiency. Because of the limitations of the programming tools and hardware interfaces, a host (whether raspberry group 4B or Windows computer) can typically only mirror one CM4 module per unit time. The image file of a complete Linux system is often very large and varies from hundreds of MB to several GB, which results in a long time consuming single burning process, which may be as long as ten minutes or more. Such inefficiency is acceptable during product development, testing, or low volume production. However, when faced with high volume product production requirements, this "one" serial burn mode becomes a serious production bottleneck. The production cycle is greatly prolonged, the time cost and the labor cost are increased, and the requirements of modern high-efficiency production cannot be met. Further, the prior art has the technical problems that first, a unified device management and task scheduling mechanism is lacked. When multiple burning hosts need to be managed simultaneously, an operator needs to manually configure, start and monitor each host one by one, which is not only inefficient, but also easy to cause burning failure or inconsistent data due to human misoperation. Second, the existing scheme is insufficient in terms of hardware integration level. Multiple independent hosts mean more power lines, network lines and peripheral connections, resulting in complex wiring, large space occupation, and difficult maintenance. Third, heat dissipation and power supply issues are
