Re: [avr-chat] Problem writing fuse bytes to atmega128 - timeout error

Hi Graham,

thanks for your support.

Now I'm also at little bit confused. I though that programming at the 
JTAG interface is the same as using a JTAG programmer.

My board is the Ethernut 1.3 Hardware PCB Version 1.3 Revision G. 
(http://www.ethernut.de/en/hardware/enut1/index.html) It is not the 
STK500 hardware.
The cable I use to program the ATmega128 is called SP Duo 
(http://www.embedded-creations.com/spduo/overview.htm).

Currently I write my own software for the board. Later we will develop 
an own board with special hardware components. Now I am writing SW for 
the ATmega128 processing telecommunication tasks.

I hope we could clear the misunderstandings.
