IDA - Read/Write Tracing

Question

I have IDA Pro 6.6, and I'm trying to trace read/write access to some address.

According to the documentation it is possible, and there are "nice" menu options under Debugger->Tracing menu: "Add write trace", "Add read/write trace", "Add execution trace".

I would be happy to try these, but no matter what I've tried all the mentioned menu options are disabled (grayed out). What do I need to do in order to be able to use these options?

Answer 1

Finally I've found: mentioned options are available only from disassembly view, not from hex view. Just place a cursor within disassembly view and right-click menu, as well as main Debugger->Tracing menu will have these options enabled.
