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).

  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
