Error detecting device

Abstract

The invention discloses an error detecting device, having a connection port and a control module, wherein the connection port is configured to electrically connect the embedded controller of the motherboard through the communication channel, the control module is electrically connected to the connection port and configured to obtain a status signal from the embedded controller via the connection port according to the communication protocol, the status signal is used to indicate the operational status of the components associated with the motherboard, the communication channel is a user electronic control channel of a high-quality multimedia interface, and the communication protocol is associated with the user's electronic control channel.

Description

technical field [0001] The invention relates to an error detection device, in particular to an error detection device for a motherboard. Background technique [0002] Generally speaking, computer equipment, such as a desktop computer or a notebook computer, usually performs a power on self test (POST) when it is turned on, so as to perform a basic input output system (basic input output system, Under the guidance of the BIOS), check whether the components on the motherboard or the components electrically connected to the motherboard are faulty. The basic input and output system will generate a POST code (power on self test code, POST code) according to the detected results during the POST stage, or called a debug code or a debug code (debugcode), as a record of the POST process . [0003] During the R&D stage, the motherboard will be equipped with an LPC debug header (Low pin count debug header, LPCdebug header) bus interface, which is convenient for R&D personnel to captu...
