Continue, break or step not working (TRACE32)

[iebold]

Also, neither continue, break or step is working (nothing printed in the log when I press the buttons in VSCode).

@wwbenayed: you should at least see the TCF message being sent for continue / step. Please provide more info.

[wwbenayed]

When I press continue or step, I don't see any new TCF message in the log. Only the CALL STACK switch to "Running"

[iebold]

This is not enough information.

Did you short-circuit the handshake as not to load all the runcontrol contexts?

Note that according to the spec https://download.eclipse.org/tools/tcf/tcf-docs/TCF%20Service%20-%20Run%20Control.html#CmdResume

Only contexts with HasState = true can be resumed.

[wwbenayed]

HasState is true. Here is the complete log:

Oh, I think you found a bug. We do fallback on RunControl if ContextQuery is missing but we don't build the context info correctly.

[iebold]

I suspect https://github.com/intel/vscode-tcf-debug/releases/tag/v0.2.7 fixes this.

Please reopen if the bug remains and you have more info.
