ABSTRACT:
A system and method for loopback self testing. A system includes a host device and an endpoint device. The host device transmits unencoded test symbols. The endpoint device loops back the unencoded test symbols to the host device. The host device drives at least some bits of each unencoded test symbol onto host device data signals and drives at least some bits of each unencoded test symbol onto host device control signals.
