Abstract

A processing system interconnect link training system includes a processing system that includes a secondary processing subsystem that is coupled to a first primary processing subsystem and a second primary processing system which are coupled to each other via a processing system interconnect that includes a plurality of processing system links. The secondary processing subsystem trains, during a boot operation and according to a first link configuration, the plurality of processing system links. Then the secondary processing subsystem determines that the training of the plurality of processing system links fails and, in response, retrains the plurality of processing system links according to a second link configuration that is a downgraded configuration relative to the first link configuration. The second processing subsystem then determines that the retraining of the plurality of processing system links according to the second link configuration was successful and, in response, continues with the boot operation.
