[En-Nut-Discussion] Ethernut 3 programming adapter

[Harald Kipp]

Henrik,

Unfortunately the SP Duo MCU is filled up, no change to
add the ARM JTAG routines. Thus, we need to distinguish
the Ethernut 3 programmer clearly from the AVR type.
It will be named "Turtelizer" and, like all previous
Ethernut programmers, it will come with a different
hardware but in the same housing. Here's the history:

1. STK200 compatible SPI programmer for the parallel port.
Delivered with early, green Ethernuts and green LED.

2. STK500 compatible SPI programmer for the serial port
and yellow LED. That was named SISP.

3. STK500 compatible SP Duo for JTAG and SPI programming
via the serial port and dual color red/green LED.

4. Turtelizer for ARM JTAG programming. Non-standard
protocol over the serial port.

As an alternative, one may use the famous Wiggler
http://www.macraigor.com/wiggler.htm
or one of its clones, see
http://hri.sourceforge.net/tools/jtag_faq_org.html
But in this case a 20-pin to 10-pin adapter is required.

For the software part I currently use
http://jtagomat.sourceforge.net/
with some new modifications.
