the tools stk500 (STK500 command line programmer, v 2.2 Atmel Corp (C) 
2004-2005.) and avrdude I took from Nut/OS installation (Ethernut 4.2.1) 
(see http://www.ethernut.de/en/download/index.html). With both tools I 
have tried to program the Ethernut board over SP Duo.

Sorry, the special cable for JTAG programming I do not have.

Where is the difference between programming with SP Duo and with special 
JTAG cable?
