tracing tools

[Xavier Raynaud]

Hi,

I just started to investigate around trace tools available for RTEMS.

Of course, I had a look at 
http://www.rtems.org/wiki/index.php/RTEMS_Trace_Tool (and 
http://code.google.com/p/rtems-tracing), but the status of this tool is 
not clear (and the wiki page said to contact Chris Johns for further 
details - here I am).

My questions are:
- What's the status of this tool ?
- How it works ? As far as I understand, it's an instrumentation at 
source level, with function wrapping. Am I right ?

Many thanks,

Xavier Raynaud
