Abstract:
1. A method for debug testing of an electronic device, comprising: receiving debug data from a plurality of blocks; buffering the debug data in a buffer; operatively coupling an output of the buffer to at least one high-speed serial Input/Output (I/O) interface on the electronic device during debug test operations, wherein each of the at least one high-speed serial I/O interface is associated with a non-debug function during normal operation of the electronic device; and sending buffered debug data outbound from the electronic device via the at least one high-speed serial I/O interface, wherein at least one high-speed serial I/O interface comprises an HDMI port having a plurality of I/O pins, and wherein multiple lanes of serialized debug data is transferred from the HDMI port by sending differentiated signals over selected I/O pins from amongst the plurality of I/O pins.
