Port Error Recovery and Resynchronization Application Note
●This document provides the RapidIO system developer with the knowledge to understand when software assisted error recovery is required and the mechanisms used to recover from an error. It also details an example implementation for handling errors.
●This application note discusses the following:
■“Overview” on page 3
■“Serial RapidIO PCS and LP-Serial Protocol” on page 4
■“Sample Link Recovery Implementation” on page 9
●Error recovery must be part of reliable system design. The Serial RapidIO protocol provides automatic error recovery in most circumstances. However, in some cases, software is expected to initiate error recovery. These cases include:
■Device reset
■Hot replacement of a system component
■Loss of a reliable physical connection between devices
■Many AMCs, and similar modules, use IDT switches because of their error recovery functions.
