RapidIO II MegaCore Function User Guide Erroneously Indicates link-response With port_status Value of Error Causes Fatal Error

Environment

  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT

    Critical Issue

    Description

    The RapidIO II MegaCore Function User Guide states that when the IP core receives a link-response control symbol with port_status value of Error, the IP core output port error recovery state machine drops all stored packets and enters the fatal_error state, and consequently sets the PORT_ERR bit of the Port 0 Error and Status CSR.

    However, this description is incorrect. The IP core conforms to paragraph 3.4.6 of the RapidIO Interconnect Specification v2.2 Part 6: LP-Serial Physical Layer Specification, which requires that the status reported in the port_status field be informational only.

    Resolution

    This issue is fixed in version 14.0 of the RapidIO II MegaCore Function User Guide.
