1027 / 1302 page  RapidIO Errors MPC8540 PowerQUICC III Integrated Host Processor Reference Manual, Rev. 1 Freescale Semiconductor 17-103 Inbound packet with unexpected ackID Received packet with unexpected ackID value (out-of-sequence ackID) Sends “PACKET_NOT_ ACCEPTED” ack with “Received unexpected ackID with packet” cause No information logged in capture register(s) Inbound packet with bad CRC Received packet with a bad CRC value Sends “PACKET_NOT_ ACCEPTED” ack with “Bad CRC” cause No information logged in capture register(s) Embedded training Requested training pattern is embedded in a packet Sends “PACKET_NOT_ ACCEPTED” ack with “General error” cause No information logged in capture register(s) Inbound packet exceeds 256 bytes Received packet that exceeds the maximum allowed size by the Parallel RapidIO Interconnect Specification. This controller performs this function by detecting a data payload greater than 256 bytes. Sends “PACKET_NOT_ ACCEPTED” ack with “General error” cause No information logged in capture register(s) Packet-not-accepted: Encountered internal error Received ack control symbol with packet-not-accepted of type “encountered internal error” Starts link recovery process. No information logged in capture register(s) Packet-not-accepted: Unexpected ackID on packet Received ack control symbol with packet-not-accepted of type “unexpected ackID” Starts link recovery process. No information logged in capture register(s) Packet-not-accepted: Corrupt control symbol Received ack control symbol with packet-not-accepted of type “corrupt control symbol” Starts link recovery process. No information logged in capture register(s) Packet-not-accepted: Input port stopped Received ack control symbol with packet-not-accepted of type “input port stopped” Starts link recovery process. No information logged in capture register(s) Packet-not-accepted: Bad CRC Received ack control symbol with packet-not-accepted of type “Bad CRC” Starts link recovery process. No information logged in capture register(s) Packet-not-accepted: S-bit parity error Received ack control symbol with packet-not-accepted of type “S-bit parity error” Starts link recovery process. No information logged in capture register(s) Packet-not-accepted: general error Received ack control symbol with packet-not-accepted of type “General error”. This error type could be created because of header/data problems at the receiver. Starts link recovery process. No information logged in capture register(s) Unexpected restart-from-retry symbol Received a restart-from-retry control symbol while in the “OK” state Starts link recovery process. No information logged in capture register(s) Unsolicited ack symbol Received an ack control symbol while no packets are outstanding on the ack history queue Starts link recovery process No information logged in capture register(s) Table 17-100. Recoverable Errors Detected by RapidIO Controller (continued) Error Description Action Capture Registers |
