Another question,
If you've the time, could you explain this phrase
"The JTAG ICE's "step over" instruction can only be used the way AVR
Studio 4 uses it, by prior filling the tag memory"
I'm not able to understand what the prior filling part is about...
Anyway I'll try to write a simple gdb macro to emulate the step over
functionality...
thanks again
