That's probably the best thing to do. "X us have passed" probably aren't, in and of themselves, interesting events.
What do you mean I have to provide a description of the messages? They just contain the message source ID (there are multiple trace sources within the trace peripheral for hardware messages, software (printf-like) messages, and instruction tracing), and the message raw data, nothing special.
Then you'd say that a message consists of an n-byte message source ID in whatever byte order it's in if n > 1, followed by some number of bytes of payload; a reference to an ARM document, even if you have to be a Registered Customer to see it, would suffice as a description of the payload. Presumably the number of bytes of payload would be the total packet length minus the length of the message source ID. See http://www.tcpdump.org/linktypes.html for examples of how link-layer header types are described. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
