RJCP.Diagnostics.Log.Dlt Project

1. DLT Trace Reader

The DLT Trace Reader implements version 1 of the AutoSAR Diagnostics Log and Trace Protocol Specification R20-11.

It is used by the DltDump application.

1.1. Reading

It implements reading streams from:

It supports the AutoSAR DLT version 1 packet, in three variants:

  • As a network stream, i.e. in the format streamed from logging devices
  • Stored on disk, with a storage header
  • Sent over serial port with an (undocumented) serial header, in the same format as the Covesa DLT Viewer.

It can interpret Non-Verbose streams based on the FIBEX file format and convert them to a verbose string.

It supports most of the data types defined in the AutoSAR standard, including:

  • Boolean BOOL
  • Signed Int SINT
  • Unsigned Int UINT
    • With additional Integer Coding (Hex, Octal, Binary, Decimal)
  • Float FLOA
  • Raw RAWD
  • Strings STRG
    • With String Coding ASCII and UTF-8 (SCOD) being stricter than Covesa.

Not implemented are:

  • Arrays ARAY
  • Structures (STRU)
  • Variable Info (VARI)
  • Fixed Point (FIXP)
  • Trace Info (TRAI)

It adds extra heuristics to try and determine corrupted data, by checking the length of verbose payloads with the packet payload (looking for errors in datastreams), and tries to synchronise where possible.

The output of the string tries to be compatible with the same output given by the Covesa DLT Viewer.

1.2. Constraints

Various constraints are added for fast filtering of DLT lines.

  • DltAppId
  • DltCtxId
  • DltEcuId
  • DltIsControl
  • DltIsVerbose
  • DltMessageId
  • DltMessageType
  • DltSessionId

These can be used in addition the constraints defined by the RJCP.Diagnostics.Log package.

1.3. Control Messages

The reading and interpreting of various control messages over multiple versions of the standard is supported (so long as the control message identifiers don't conflict).

The X indicates the control message is implemented.

2. DLT Trace Writer

The DltTraceWriterFactory allows to create a DltTraceWriter that can be used to write a trace line to disk. This allows one to implement tooling to read log files (e.g. event logs, journals) and write out as DLT (for example, over the network).

It supports writing verbose and control messages, as DLTv1 packets.

It does not support writing non-verbose messages.

If access to the raw payload is needed, extend the DltTraceDecoderBase.CheckLine in your own class. The payload is not exposed to a DltTraceLine to avoid an unnecessary copy. This could allow reading a packet that is a non-verbose raw message, and instead of using the DltWriter, write the original line (for example, this filtering is done by DltDump).
