LogiCORE RapidIO v4.4/v5.1 - Why am I seeing long initialization times with the Virtex-4 Serial RapidIO solution?

Description

When testing the core in hardware, why am I seeing initialization times of ~30-45 seconds before the link is successfully trained?

Solution

Attributes are used to correctly constrain the initialization state machine, and one attribute is not being passed correctly. As a result, the initialization state machine fails to train in the expected timeframe (worst case ~1 second).  

 

A patch is available for the Serial RapidIO v5.1 core to fix this issue. See (Xilinx Answer 31573) for details.
