RapidIO MegaCore Function User Guide Has Incorrect Information About the Port 0 Error and Status CSR - RapidIO MegaCore Function User Guide Has Incorrect Information About the Port 0 Error and Status CSR Description According to the RapidIO MegaCore Function User Guide , any of the following three link protocol violations causes the RapidIO IP core input port to transition to the Input Error Stopped state, setting the IN_ERR_STOP bit of the Port 0 Error and Status CSR (offset 0x158): Unexpected packet-accepted control symbol Unexpected packet-retry control symbol Unexpected packet-not-accepted control symbol However, these conditions do not affect the input port. Instead, they cause the RapidIO output port to transition to the Output Error Stopped state, and set the OUT_ERR_STOP of the Port 0 Error and Status CSR . Resolution This issue has no workaround. Ensure you use the explanation in this erratum to interpret the values in the Port 0 Error and Status CSR. This issue is fixed in version 17.0 of the RapidIO IP Core User Guide .
