Description

[0002] The rapid development of the internet has also brought prosperity to the server market. The BMC (Baseboard Management Controller) plays a crucial role in monitoring and managing servers. In the early stages of BMC firmware development, resources are limited, often consisting of only a motherboard with a lack of peripherals. Development often involves writing code first, without physical access to many peripherals, hindering troubleshooting. Debugging only begins on physical devices once the necessary resources arrive, often resulting in tight deadlines and a long gap between coding and debugging, hindering rapid problem resolution. Furthermore, some devices are expensive, such as the latest GPUs (Graphics Processing Units). A company might only have one GPU, with some needing performance testing, others compatibility testing, and still others stability testing, making coordination extremely difficult. The main reasons are: lack of equipment, difficulty in coordinating equipment availability, insufficient code development and testing, project delays, and difficulty ensuring everyone has access to a complete set of equipment when developing with multiple developers.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Currently, in the early stages of server BMC firmware development, the R&D team has limited resources. Therefore, during development, they can only write code first. Many peripheral devices do not have actual equipment, making it impossible to troubleshoot problems in the early stages. This leads to a mismatch between development and testing, which slows down the development progress and causes project delays.

[0047] To address this issue, this application provides a simulation debugging solution that can resolve the problem of inconsistent development and testing paces caused by the lack of or absence of equipment during the development of BMC, which slows down the development progress and leads to project delays.

[0048] This invention discloses a simulation debugging method, see [link to relevant documentation]. Figure 1 As shown, the method is applied to a programmable microcontroller, which includes a power supply interface, a DIP switch, a device simulator, and a baseboard management controller connector. The method includes:

[0049] Step S11: Power is supplied through the power supply interface and the target firmware is downloaded.

[0050] This application provides a realistic simulator based on a programmable microcontroller unit (MCU, also known as a single-chip microcomputer) powered via a USB (Universal Serial Bus) interface, thus offering flexible power supply options.

[0051] In this embodiment, after power is supplied via the USB interface, different target firmware can be downloaded according to different communication protocols and specifications corresponding to different communication devices. For example, in a programmable microcontroller, if it is necessary to simulate an NVME (Non-Volatile Memory Express) hard drive, then the communication protocol corresponding to the NVME hard drive, such as MCTP (Management Component Transport Protocol) over I2C (Inter-Integrated Circuit) protocol, is downloaded. It can be understood that the MCTP over I2C protocol means that the underlying protocol of this Management Component Transport Protocol is ultimately transmitted via I2C.

[0052] Step S12: Switch the device simulator using the DIP switch to simulate various communication devices corresponding to the target firmware.

[0053] In this embodiment, the downloaded target firmware can simulate the required peripheral devices; that is, different device firmwares correspond to different DIP switches. Therefore, during the simulation process, the device simulator can be switched with a single click by adjusting the DIP switches, thereby simulating various types of devices.

[0054] In this embodiment of the application, the simulated communication devices corresponding to the target firmware may include temperature sensors, NVME hard drives, EEPROM (Electrically Erasable Programmable Read-Only Memory), GPU cards, etc., and may also simulate network cards or simulate external voltages, without specific limitations.

[0055] Specifically, the step of switching the device simulator via the DIP switch to simulate various communication devices corresponding to the target firmware includes: switching the device simulator via the DIP switch to simulate a temperature sensor; or, switching the device simulator via the DIP switch to simulate an NVMe hard drive; or, switching the device simulator via the DIP switch to simulate a electrically erasable programmable read-only memory; or, switching the device simulator via the DIP switch to simulate a GPU card; or, switching the device simulator via the DIP switch to simulate a network card; or, switching the device simulator via the DIP switch to simulate voltage.

[0056] Step S13: Obtain the communication protocol of the communication device simulated by the device simulator through the board management controller connector, and communicate with the board management controller according to the communication protocol to simulate monitoring and management of the board management controller.

[0057] In this embodiment, since some of the devices monitored and managed by the baseboard management controller are based on the I2C communication protocol, they can be connected to the motherboard of the baseboard management controller via an I2C cable to communicate with the baseboard management controller according to the communication protocol, thereby simulating various I2C devices monitored and managed by the baseboard management controller.

[0058] In this embodiment, the different communication protocols corresponding to the simulated different types of devices may include SMBUS (System Management Bus) protocol, FRU (Field Replace Unit) protocol, MCTP over I2C protocol, etc., or may be read from general I2C device registers, without specific limitations here. Among them, the I2C device is a device that monitors and manages the baseboard management controller based on the I2C communication protocol.

[0059] Specifically, obtaining the communication protocol of the communication device simulated by the device simulator through the baseboard management controller connector includes: obtaining the system management bus protocol of the communication device simulated by the device simulator through the baseboard management controller connector; or, obtaining the field replaceable unit protocol of the communication device simulated by the device simulator through the baseboard management controller connector; or, obtaining the MCTP over I2C protocol of the communication device simulated by the device simulator through the baseboard management controller connector; or, obtaining the protocol read from the general-purpose I2C device register simulated by the device simulator through the baseboard management controller connector.

[0060] In this embodiment, when the device simulator is switched via the DIP switch, the slave address of the programmable microcontroller can be changed at any time to simulate various communication devices corresponding to the target firmware. This allows for dynamic configuration of the physical addresses of communication devices monitored and managed by various baseboard management controllers, ensuring consistency with real devices.

[0061] This application utilizes a programmable microcontroller, which includes a power supply interface, a DIP switch, a device simulator, and a baseboard management controller connector. The method first supplies power and downloads the target firmware through the power supply interface; then, the device simulator is switched via the DIP switch to simulate various communication devices corresponding to the target firmware; finally, the communication protocol of the communication device simulated by the device simulator is obtained through the baseboard management controller connector, and communication is established with the baseboard management controller according to the communication protocol to simulate monitoring and management of the baseboard management controller. Therefore, this application, based on a programmable microcontroller, provides a realistic physical device capable of simulating various communication devices for monitoring and management of baseboard management controllers. This solves the problem of inconsistent development and testing paces caused by the lack of or absence of equipment during baseboard management controller development, which slows down development progress and leads to project delays. Furthermore, the one-click switching of the device simulator via the DIP switch does not affect the compatibility of the device between different projects, improving development efficiency. This ensures that the baseboard management controller has physical devices available at any time during the development process, and that multiple devices and configurations are always available. This allows for thorough testing in the early stages, and the earlier problems are discovered, the more likely project delays can be avoided. It also solves the problem of insufficient resources in the early stages, ensures that development and testing are not disconnected, and guarantees the smooth progress of the project.

[0062] This application discloses a schematic diagram of a programmable microcontroller. (See also...) Figure 2 As shown, the device includes: a power supply interface, a DIP switch, a device simulator, and a board management controller connector; wherein,

[0068] like Figure 3 The diagram shows a specific simulation debugging structure. The hardware design is based on a programmable MCU, powered and firmware-downloaded via USB. The software design uses different firmware written according to the communication protocols and specifications of different devices. When simulating a device is needed, different firmware can be downloaded by adjusting different DIP switches to simulate different devices, allowing for one-click device switching.

[0069] As can be seen, based on a programmable MCU, when needed, simply toggling a DIP switch allows downloading firmware for different devices, including different communication protocols and raw data value ranges. By connecting USB for downloading and power, and connecting an I2C cable to the motherboard where the BMC resides, multiple different physical devices can be realistically simulated.

[0070] This application discloses a programmable microcontroller, including a power supply interface, a DIP switch, a device simulator, and a baseboard management controller connector. The power supply interface is used to connect to a server for power supply and downloading target firmware. The DIP switch is used to switch the device simulator to simulate various communication devices corresponding to the target firmware. The device simulator is used to simulate various communication devices corresponding to the target firmware. The baseboard management controller connector is used to acquire the communication protocol of the communication device simulated by the device simulator and communicate with the baseboard management controller according to the communication protocol to simulate monitoring and management of the baseboard management controller. Therefore, this application, based on a programmable microcontroller, provides a real physical device capable of simulating various communication devices for monitoring and management of baseboard management controllers. This solves the problem of inconsistent development and testing paces caused by the lack of or absence of equipment during the development of baseboard management controllers, which slows down development progress and leads to project delays. Furthermore, the one-click switching of the device simulator via the DIP switch does not affect the compatibility of the device between different projects, improving development efficiency. This ensures that the baseboard management controller has physical devices available at any time during the development process, and that multiple devices and configurations are always available. This allows for thorough testing in the early stages, and the earlier problems are discovered, the more likely project delays can be avoided. It also solves the problem of insufficient resources in the early stages, ensures that development and testing are not disconnected, and guarantees the smooth progress of the project.

[0071] Accordingly, this application also discloses a simulation debugging device, see [link to relevant documentation]. Figure 4 As shown, this device is applied to a programmable microcontroller, which includes a power supply interface, a DIP switch, a device simulator, and a board management controller connector. The device includes:

[0072] Power supply module 11 is used to provide power and download target firmware through the power supply interface;

[0073] The communication device simulation module 12 is used to switch the device simulator via the DIP switch to simulate a variety of communication devices corresponding to the target firmware;

[0074] The communication module 13 is used to acquire the communication protocol of the communication device simulated by the device simulator through the baseboard management controller connector, and to communicate with the baseboard management controller according to the communication protocol to simulate monitoring and management of the baseboard management controller.

[0075] For more detailed information on the working process of each of the above modules, please refer to the relevant content disclosed in the foregoing embodiments, which will not be repeated here.

[0076] Therefore, the above-described solution in this embodiment, applied to a programmable microcontroller, includes a power supply interface, a DIP switch, a device simulator, and a baseboard management controller connector.

Thus, this application, based on a programmable microcontroller, provides a realistic physical device capable of simulating various communication devices for monitoring and management of baseboard management controllers. This solves the problem of inconsistent development and testing paces caused by the lack of or absence of equipment during the development of baseboard management controllers, which slows down development progress and leads to project delays. Furthermore, the one-click switching of the device simulator via the DIP switch does not affect the compatibility of the device between different projects, improving development efficiency. This ensures that the baseboard management controller has physical devices available at any time during the development process, and that multiple devices and configurations are always available.
