Serial RapidIO v5.5 - Core receives unexpected "Packet Not Accepted" control symbols


In some instances, the core might insert idle sequences before the end of a packet. This is a protocol violation that ends up causing the link partner to send a "Packet Not Accepted" control symbol, and the link recovers from this error.


This is due to a problem in the core that is scheduled to be fixed in the v5.6 core which is to be released with the v13.1 tools.

Thereis to bea slight impact on the core's performance. However, the link recovers from the error.
