1. A system, comprising:
a processing resource; and
a memory device, wherein the memory device is coupled to the processing resource via a first transmission link and wherein the processing resource is configured to test the first transmission link in response to detecting the memory device failing to execute a command by sending the command to the memory device again as a retry command and monitoring the first transmission link for one or more signals that indicate whether the retry command was executed by the memory device, and wherein a command descriptor for the retry command includes a retry flag that allows the memory device to differentiate between the retry command and the command.
