Technical Field

[0002] With the rapid development of electronic technology, firmware burning has become an indispensable part of electronic equipment production and maintenance. As the core software of the device, the correct and efficient burning of firmware directly affects the performance and stability of the device. However, in actual operation, boards of different models and manufacturers often use different communication interfaces and protocols, which brings great challenges to firmware burning.

[0003] Traditional firmware burning methods usually rely on specific burning tools and equipment, which makes it difficult to achieve cross-platform and cross-protocol universality, resulting in low production efficiency and high costs.

[0004] In addition, with the popularization of network technology, the demand for firmware burning through the network is also increasing. Traditional serial or parallel port communication methods can no longer meet the needs of large-scale, remote, and automated firmware burning. Therefore, it is particularly important to develop a fixture that integrates multiple protocol serial ports and can burn firmware through the network. Summary of the invention

[0010] By integrating the protocol conversion module and multiple serial ports, it is compatible with a variety of hardware boards. The firmware burning fixture integrates the functions of power conversion, protocol conversion, communication interface, etc. The user only needs to connect the board to be burned to the fixture through the corresponding interface, and then input the burning parameter information through the first communication interface to complete the firmware burning process. This design simplifies the operation process, reduces the difficulty of operation, and improves work efficiency.

[0011] As a preferred embodiment of the technical solution of the utility model, it also includes a physical layer chip arranged between the baseboard management controller and the first communication interface, and the physical layer chip is used for converting between digital signals and analog signals.

[0012] In addition, the first communication interface and physical layer chip are introduced to burn the firmware through the network, which further improves the versatility and flexibility.

[0013] The introduction of the first communication interface allows users to perform firmware burning operations on the board at a remote location without having to be on site. This avoids the additional costs caused by frequent replacement of burning equipment or adjustment of burning parameters. At the same time, by improving production efficiency and reducing operational difficulty, it also indirectly reduces the overall cost.

[0014] By integrating the first communication interface and the physical layer chip, the firmware burning fixture has powerful network communication capabilities. This allows users to remotely access and control the burning process through the network, greatly improving the flexibility and convenience of operation. The connection between the power conversion module and the physical layer chip enables the fixture to manage power more efficiently. The physical layer chip may require a specific power supply when performing network communication, which improves the stability and reliability of the overall system.
