1 is a block diagram of a preferred embodiment of a substrate management controller status detection system of the present invention.

2 is a flow chart of a preferred embodiment of a substrate management controller state detection method according to the present invention.

Referring to FIG. 1 , a preferred embodiment of the substrate management controller state detection system of the present invention includes a motherboard 100 and a Baseboard Management Controller (BMC) 200. The motherboard 100 is connected to the BMC 200 through an Intelligent Platform Management Interface (IPMI) or an Inter-Integrated Circuit (I2C) bus.

In this embodiment, the motherboard 100 is configured to perform real-time detection on the running status of the BMC 200. The motherboard 100 includes a first transmitting module 10, a first receiving module 20, a flash memory 30, a determining module 40, and a prompting module 50.

In this embodiment, the first sending module 10 is configured to send a status detection command to the BMC 200 at each interval (eg, 60 s). The state detection instruction is used to control the BMC 200 to return a return value after receiving the instruction. The receiving module 20 is configured to receive a return value of the BMC 200.

In this embodiment, the flash memory 30 is configured to store a system event log (SEL) generated when the BMC is in an abnormal working state. The SEL is used to record error information of the BMC 200 when it is in an abnormal working state, and the error information includes time, error reason, and the like.

In this embodiment, the determining module 40 is configured to determine whether the first receiving module 20 receives the return value of the BMC 200 within a preset time (eg, 5 s). The duration of the interval is greater than the duration of the preset time.

When the first receiving module 20 receives the BMC 200 return value within the preset time, it is determined that the BMC 200 is in a normal working state.

When the first receiving module 20 does not receive the return value within the preset time, it is determined that the BMC 200 is in an abnormal working state, and the first sending module 10 of the motherboard 100 sends a system control interrupt (System). Control Interrupt (SCI) commands to the BMC 200 to reset the BMC 200. After the BMC 200 completes the reset, the motherboard 100 stores the SEL generated by the BMC 200 into the flash memory 30.

In the embodiment, the prompt module 50 is configured to display prompt information to prompt the working state of the BMC 200. The prompt information may be different colors and the like displayed by the light emitting device on the motherboard 100.

In this embodiment, the BMC 200 includes a second sending module 60 and a second receiving module 70. The second receiving module 70 is configured to receive a state detection command and a system control interrupt command sent by the first sending module 10. The second sending module 60 is configured to return a return value to the first receiving module 20 after receiving the state detecting command sent by the first sending module 10 .

In operation, the first transmitting module 10 of the motherboard 100 transmits a status detection command to the BMC 200. At this time, the determining module 40 determines whether the first receiving module 20 receives the return value of the BMC 200 within a preset time. If the first receiving module 20 receives the BMC 200 return value within the preset time, it is determined that the BMC 200 is in a normal working state. The prompt module 50 outputs a first prompt information (eg, the light emitting device of the motherboard displays yellow). If the first receiving module 20 does not receive the return value within the preset time, and determines that the BMC 200 is in an abnormal working state, the first sending module 10 of the motherboard 100 sends a system control interrupt command to the BMC 200. To reset the BMC 200. After the BMC 200 completes the reset, the motherboard 100 stores the SEL generated by the BMC 200 into the flash memory 30. At the same time, the prompt module 50 outputs a second prompt information (eg, the light emitting device of the motherboard displays red).

Referring to FIG. 2, a preferred embodiment of the substrate management controller state detecting method of the present invention includes the following steps:

In step S100, the first sending module 10 of the motherboard 100 sends a status detection command to the second receiving module 70 of the BMC 200. The status detection instruction is used to control the BMC 200 to return a return value after receiving the instruction. The motherboard 100 communicates with the BMC 200 through an Intelligent Platform Management Interface (IPMI) or an Inter-Integrated Circuit (I2C) bus.

In step S102, the determining module 40 determines whether the first receiving module 20 receives the return value of the BMC 200 within a preset time. If the first receiving module 20 receives the return value within the preset time, the process proceeds to step S104; if the first receiving module 20 does not receive the return value within the preset time, the process proceeds to step S108.

In step S104, the determination module determines that the BMC 200 is in a normal working state.

In step S106, the prompting module 50 outputs the first prompt information (for example, the light emitting device displays yellow).

In step S108, the determination module determines that the BMC 200 is in an abnormal working state. The first transmitting module 10 sends a system control interrupt command to the BMC 200 to reset the BMC 200.

In step S110, the motherboard 100 stores the SEL generated by the BMC 200 into the flash memory 30.

In step S112, the prompting module 50 outputs a second prompt information (eg, the light emitting device displays red).

The substrate management controller status detection system and method are configured to detect whether the BMC 200 is operating normally through the status detection command sent by the first sending module 10, and when the BMC 200 is not operating normally, the first sending module 10 The system control interrupt command is sent to the BMC 200 to reset the BMC 200 and store the SEL generated by the BMC 200 into the flash memory 30. At the same time, the prompt module 50 outputs a second prompt information to prompt the user to perform corresponding processing. In this way, the BMC 200 can continuously monitor the system to ensure the stability of the system.
