Fault information detection method and electronic device

Abstract

The present invention provides a fault information detection method and an electronic device. Communication connection between a management engine ME chip and a control chip is established through a connecting bus. When the ME chip is abnormal, fault data are sent to the control chip through the connecting bus, the fault data are output by the control chip, operation conditions of the ME chip can be monitored in real time without extra detection equipment and without opening a cabinet, operation complexity is reduced, and related personnel can find the problem and solve the problem timely.

Description

technical field [0001] The present invention relates to the technical field of management engine chips, and more specifically, to a fault information detection method and electronic equipment. Background technique [0002] At present, in electronic equipment based on the Intel (Intel) platform, an ME (Management Engine, management engine) chip is integrated on the Intel PCH (Intel's integrated south bridge) chip of the electronic equipment, and the ME chip is used to be responsible for the electronic equipment. Many important functions, such as system configuration and dynamic remote management, etc., will affect these functions after the ME chip fails. For example, a problem has been encountered in practical applications: the ME chip enters the repair mode probabilistically, and this problem cannot be solved. It will affect the shipment of electronic equipment, so it can be seen that the detection of the failure of the ME chip is very necessary. [0003] There are currentl...

[0002] At present, in electronic equipment based on the Intel (Intel) platform, an ME (Management Engine, management engine) chip is integrated on the Intel PCH (Intel's integrated south bridge) chip of the electronic equipment, and the ME chip is used to be responsible for the electronic equipment. Many important functions in the system, such as system configuration and dynamic remote management, will affect these functions after the ME chip fails. For example, a problem has been encountered in practical applications: the ME chip enters the repair mode probabilistically, and this problem cannot be solved. It will affect the shipment of electronic equipment, so it is very necessary to detect the failure of the ME chip after the failure

[0003] There are currently two ways to detect ME chips: the first is to connect the ME chip to multiple hosts through a LAN (Local Area Network) or directly connect the ME chip to other ME detection devices during the development stage of electronic equipment. On the device, use these devices to detect the failure of the ME chip, but this method requires that the ME chip is not locked, and this method cannot simulate the actual application situation

[0004] In order to solve the problems caused by the first detection method above, a second detection method is proposed for the ME chip locked situation, and the ME chip will internally record the operation of the ME chip in practical applications, so that after the ME chip fails, it can Unpack the electronic equipment, and read the fault information obtained when the ME chip records the operation status after disabling the ME chip, but this detection method may cause damage to the electronic equipment, and the operation complexity is high
