- What advantages gives Nexus in comparison with JTAG?
- What processors/microcontrollers with support Nexus besides AVR32 exist?
- Who releases debugging means with Nexus?

The Nexus gives you non-intrusive real time trace. The standard is a Nexus class 3+, which is the only processor as far as I know. Ashling has a tool called Vitra which enables these features. Check http://www.nexus5001.org/ and http://www.ashling.com/ for details

This, apart from just being truly awesome, is required by some software QA specs.

But yeah, this particular standard (Nexus 3+) is pretty new, in fact I think a selling point of the AP7 family is that they were the first family in the world to implement what is a very powerful debug standard.
