Hi,
I have 2 LetATwork board:
1 : with a atmega103
2: with a atmega128
I also have two programmers:
1: Kandra prg. works on LPT Port
2: AVRISP II works on USB ( latest firmware)
Here is the thing...my Kanda programmer works with both boards...but the AVRISP programmer does not work with the ATmega128 board but it does work with the atmega103 board.
it works with all other board just not with the atmega128...
Looking at the schematic of the letATwork boards...there is no hardware difference between the 103 and the 128 version.
Could it be a fusebit problem?
Anyone an idea?
 

This problem was solved ...there is a resistor on the board that caused this. In the new version this resistor is changed.
look for the resistor on the reset line
