Version Found: v5.5
When the Serial RapidIO v5.5 core receives a Packet Not Accepted (PNA) control symbol immediately after a Packet Retry (PR) control symbol, the core does not send an LREQ-Input status in reply to the PNA. It sends only Restart-From-Retry (RFR) control symbol. However, the core starts the LRESP time-out counter and goes into the fatal error state after timing out for not receiving the LRESP.
This is a known issue that can occur if the 'Additional Link Requests Before Fatal' value in the core configuration GUI is set to "1".
To work around this problem, select a value greater than "1" for this parameter.
NOTE: "Version Found" refers to the version where the problem was first discovered. The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
