Hi @Broddo,

Apologies for the delayed in response, so if I understand correctly, you have managed to setup the JTAG configuration as as per required here.
And how for viewing the the capture variable value perhaps you can look into the Lauterbach tool, more details on how it can be done are in the guide here.
Hope that helps.

    Yes indeed - I have the JTAG configuration working. GDB debugging is working perfectly for me. But like I mentioned, I have still yet to find information on how to use the on-chip trace feature.

    Just to be clear - the Lauterbach Tool is for off-chip tracing - this is not what I'm asking about. A 3rd party tool like this is not required for on-chip tracing. The features are built directly into the NIOS2. But there doesn't seem to be a clear way of working with this feature.
