User Guide
ILL_TRAN_TARGET [26] RO (1)
Received a packet that contained a destination ID that is not
defined for this end point. Set when the RapidIO II IP core
detects this situation or when the
illegal_transaction_target_error_set
input signal
changes value from 0 to 1.
An endpoint with multiple ports and a built-in switch function
might not report this situation as an error.
1'b0
MSG_REQ_TIMEOUT (2) [25] RO (1)
A required message request has not been received within the
specified time-out interval. Set when the
message_request_timeout_set
input signal changes value
from 0 to 1.
1'b0
PKT_RSP_TIMEOUT (2) [24] RO (1)
A required response has not been received within the specified
time-out interval. Set when the RapidIO II IP core detects this
situation or when the slave_packet_response_timeout_set
input signal changes value from 0 to 1.
1'b0
UNSOLICIT_RSP [23] RO (1)
Received an unsolicited or unexpected response packet (I/O,
message, or GSM logical for endpoints; Maintenance for
switches). Set when the RapidIO II IP core detects this situation
or when the unsolicited_response_set input signal
changes value from 0 to 1.
1'b0
UNSUPPORT_TRAN [22] RO (1)
Received a transaction that is not supported in the Destination
Operations CAR. Set when the RapidIO II IP core detects this
situation or when the unsupported_transaction_set input
signal changes value from 0 to 1.
1'b0
MISSING_DATA_STRM_
CNTXT (2)
[21] RO (1)
Received a continuation or end data streaming segment for a
closed or non-existent segmentation context. Set when the
missing_data_streaming_context_set
input signal
changes value from 0 to 1.
1'b0
OPEN_EXSTG_DATA_STRM_
CNTXT (2)
[20] RO (1)
Received an initial or single data streaming segment for an
already-open segmentation context. Set when the
open_existing_data_streaming_context_set
input signal
changes value from 0 to 1.
1'b0
LONG_DATA_STRM_SGMNT
(2)
[19] RO (1)
Received a data streaming segment with a payload size greater
than the MTU. Set when the
long_data_streaming_segment_set
input signal changes
value from 0 to 1.
1'b0
SHRT_DATA_STRM_SGMNT
(2)
[18] RO (1)
Received a non-final data streaming segment with a payload size
less than the MTU. Set when the
short_data_streaming_segment_set
input signal changes
value from 0 to 1.
1'b0
DS_PDU_LEN_ERR (2) [17] RO (1)
The length of a reassembled PDU differs from the PDU length
specified in the end data streaming segment packet header. Set
when the data_streaming_pdu_length_error_set input
signal changes value from 0 to 1.
