RapidIO II IP Core Might Send Truncated Data on Avalon-ST Pass-Through Interface if tt = 1

Environment

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

    Critical Issue

    Description

    When the RapidIO II IP core sends data to the Avalon-ST Pass-Through interface in a transaction with Transport Type value 1, it truncates the payload to a multiple of eight bytes.

    Resolution

    This issue has no workaround. To avoid this issue, avoid sending payloads that are not a multiple of eight bytes in packets with ftype 9 and tt 1.

    This issue will be fixed in a future version of the RapidIO II MegaCore function for IP core variations with a 16-bit device ID. However, refer also to the erratum RapidIO II IP Core Does Not Support Streaming Data Packets With Device ID Width 16.
