DoIP UDS breakdown
A few years ago I used to be able to see detailed breakdown of Ethernet UDS traffic in Wireshark traces. I could see the commands identified in the main table (TesterPresent, RoutineControl, TransferData, etc) and a thorough breakdown of different data fields in multiple layers in the bottom-left pane. Now there's almost nothing.
This is from a pcapng that I too in October 2021. I know for a fact that I got a detailed breakdown for this because I took these traces myself and used them to help develop one of our programs here at work. and now that same file (and every other one from back then that I've tried) is breaking down nothing.
It's been a few years since I did that work, and now that I'm going to be working on something similar I tried to dust these off for to refresh my memory of some things and they are not helpful at all.
I don't know if this is something that happened because of updates in the 5 years since these traces were made or something I might have done. Other than doing the software updates the biggest change I can remember making was installing an Intrepid plugin ICS CAP (https://intrepidcs.com/products/software/ics-cap/) so I could use Wireshark with their hardware for CAN and LIN traces. Could the plugin have screwed with some things? I've tried searching documentation and google for answers but it's hard to find anything when you don't even know if you're wording your search correctly. Does anyone know what I can try?
