[En-Nut-Discussion] Newbie on board -- how to debug

[Harald Kipp]

Kelly,

Good start points are

http://savannah.nongnu.org/projects/simulavr/
http://avarice.sourceforge.net/

No need for AVR-500/501. The adapter shown at

http://www.ethernut.de/en/jtag/jtagconn.html

is included in the ATJTAGICE, which is required (300 US$).

PDP-11? Wow, that's much more versatile than an ATmega128.
I rememer the 256 Byte (!) boot loader, which can boot from
paper tape, magnetic tape and harddisks. 128 Bytes of it
were used to check the CPU. Great stuff!
