Detailed Description
LIN_RCV_ERROR2.
This event may have a wide variety of causes. An external Master can cause a receive error event:
- by transmitting sync break that is too short,
- by not returning the correct value 0x55 in the sync field,
- by assigning an incorrect parity to the frame identifier. Other reasons:
- Slave transmitting an illegal character during a Bus Idle phase (e.g. because it did not finish transmission quickly enough and the checksum byte of the response was sent during the Bus Idle phase),
- Faulty (dominant) stop bit (i.e. framing error),
- LIN hardware receives a character that is different from the character sent during transmission
- LIN hardware only receives part of a frame, at the start of a measurement (in a correctly functioning system).

Member Data Documentation
uint32_t Vector::BLF::LinReceiveError2::earlyStopbitOffset {}
Early stop bit offset for UART timestamps in ns. Early stop bit offset in frame header for UART timestamps [in ns]
uint32_t Vector::BLF::LinReceiveError2::earlyStopbitOffsetResponse {}
Early stop bit offset in frame response for UART timestamps in ns. Early stop bit offset in frame response for UART timestamps [in ns]
double Vector::BLF::LinReceiveError2::exactHeaderBaudrate {}
Exact baudrate of the header in bit/sec. Event's baudrate measured in header [in bits/sec]
uint8_t Vector::BLF::LinReceiveError2::fsmId {}
Slave Identifier in the Final State Machine (obsolete)
uint8_t Vector::BLF::LinReceiveError2::fsmState {}
State Identifier of a Slave in the Final State Machine (obsolete)
uint8_t Vector::BLF::LinReceiveError2::hasDatabytes {}
Flag indicating whether at least one data byte value is valid
uint8_t Vector::BLF::LinReceiveError2::isEtf {}
ETF collision flag. Flag indicating whether this frame is Event-Triggered one:
- 0: not ETF
- 1: ETF
uint8_t Vector::BLF::LinReceiveError2::offendingByte {}
Byte value that resulted the protocol violation. Only valid for certain values of mStateReason
uint32_t Vector::BLF::LinReceiveError2::reservedLinReceiveError {}
reserved
uint32_t Vector::BLF::LinReceiveError2::respBaudrate {}
Response baudrate of the event in bit/sec. Event's baudrate measured in response [in bits/sec]
uint8_t Vector::BLF::LinReceiveError2::shortError {}
Specifies the detail level of the event. Following values are possible:
- 0: short
- 1: full Most members are not valid unless this member is 1
uint8_t Vector::BLF::LinReceiveError2::stateReason {}
The lower 4 bits indicate the LIN hard-ware state at the time the error has occurred, while the upper 4 bits indicate the reason of the error
Value for the state:
- 0: Bus idle
- 1: Waiting for SynchBreak
- 2: Waiting for SynchField
- 3: Waiting for frame ID
- 4-12: Waiting for data byte or checksum byte depending on the frame length. E.g. value 4 for FrameLength=0, value 12 for FrameLength=8
- 14: Consecutive event (i.e. event resulting from further data interpretation, after already notified error for first offending byte)
- 15: Not expected event (i.e. not WakeupRequest) during sleep mode. Occurs for LIN hardware in Master mode only
Values for the reason:
- 0: Timeout
- 1: Received an unexpected byte violating protocol. In this case, mOffendingByte member contains its value
- 2: Received a byte with framing error (with dominant stop bit). In this case, mOffendingByte member contains its value
- 3: Unexpected Break field
- 4: Unidentified error
uint8_t Vector::BLF::LinReceiveError2::timeoutDuringDlcDetection {}
Flag indicating if the error is a result of an attempt to resolve frame length. Following values are possible:
- 0: False
- 1: True
