[En-Nut-Discussion] Development Environ - general questions

Ponyprog and all other ISP programmers use the ISP interface
of the CPU, while ATJTAGICE uses the JTAG interface.


>* ATJTAGICE (probably don't need PonyProg anymore?)

No, you don't need any programmer any more. ATJTAGICE uses
the JTAG interface of the ATmega128 for debugging as well
as software up- and downloading.


>* Is there a "startup tutorial" somewhere to answer all these questions?

Not really.


>* Is there an advantage - code quality, debug-ability, etc. with either
>AVR-GCC 3.3 or ICCAVR 2.62C ?

Both allow source code level debugging. Watching variables didn't
work with previous version of GCC, but should work now. Haven't
tried that.


>* Does everybody use AVR Studio 4.04 that has the ATJTAGICE? Are there

Both, disassembly as well as C code. See

You have to setup a Studio project, but you can still use an
external editor.


>* Has everyone moved to NutOS 2.60 ?

Don't move now. 3.0 is in the final testing.
