Detailed Description

MOST_150_MESSAGE_FRAGMENT. Partial transmitted MOST50 or MOST150 Control Channel message. Fragments are reported from a network spy if the message transmission is corrupted or terminated.

Member Data Documentation

  uint8_t Vector::BLF::Most150MessageFragment::ackNack {}

acknowledge code AckNack holds the transmit status of a control message (see Transmit Status Register of OS8104 for MOST25).

•   Bit 0: Meaning:

•   1: no response (NoResp) Restriction:

•   only for Dir = Tx or spy messages

•   Bit 1: Meaning:

•   1: valid receipt (Valid) Restriction:

•   only for Dir = Tx or spy messages

•   Bit 2: Meaning:

•   1: CRC Error (CRCError) Restriction:

•   only for Dir = Tx or spy messages

•   Bit 3: Meaning:

•   1: receive buffer full (RxBufFull) Restriction:

•   only for Dir = Tx or spy messages

•   Bit 4: Meaning:

•   1: acknowledged (Ack) Restriction:

•   only for Dir = Tx or spy messages (always set to 1 for Rx messages in node mode)

•   Bit 5: Meaning:

•   1: negative acknowledge (NAck) Restriction:

•   only for Dir = Tx or spy messages

  uint8_t Vector::BLF::Most150MessageFragment::cAck {}

CRC acknowledge from the packet receiver(s) to the packet transmitter. CRC acknowledge from the packet receiver(s) to the packet transmitter

•   0x00: No Response

•   0x01: CRC error

•   0x04: OK

  uint32_t Vector::BLF::Most150MessageFragment::dataLen {}

number of transmitted user data bytes Number of transmitted user data bytes. These bytes were counted on bus.

Note: The number of bytes saved in this event is stored in firstDataLen.

  uint32_t Vector::BLF::Most150MessageFragment::dataLenAnnounced {}

announced user data length at the start of the transmission Announced user data length at start of transmission. In some cases (e.g. sending to an invalid target address, receive buffer full of target device) the transmission is terminated before all data bytes have been sent. Then the counted number of bytes on bus is less than the announced data length (dataLen < dataLenAnnonced). Due to rare and very specific bit errors (degrade of end termination byte) dataLen can also be greater than dataLenAnnonced.

  uint32_t Vector::BLF::Most150MessageFragment::firstDataLen {}

number of bytes in firstData Number of bytes stored in mFirstData (1524 max).

Note: In order to limit the size of this event not all counted bytes on bus will be stored in the payload of the logging event.
