Abstract
The muxed HDMI debug port methods and apparatuses are directed toward means for detecting an extended display identification data (EDID) code indicating a debug cable or debug host device coupled to the high-definition multimedia interface (HDMI) port of a computing device. In addition, the methods and apparatuses include means for disabling a display data channel (DDC) bus of the high-definition multimedia interface (HDMI) port in response to the extended display identification data (EDID) code indicating the debug cable or debug host device. Furthermore, the method and apparatuses include means for transmitting and receiving debug commands and data on a serial input (RXD) and serial output (TXD) of the high-definition multimedia interface (HDMI) port in response to the extended display identification data (EDID) code indicating the debug cable or debug host device.
