The problem I'm facing is that when I try to program my atmega128 (Stk500 with Stk501) the AvrStudio can't connect to the Stk, it can't even find it. It get stuck to the window where you choose COM1,COM2 etc.
The problem occured after I tryied to program with some external parts on the STK, an analog sensor and a capacitor connected to the pins AREF and GND.
I've tested in tow different PC's ...both the same problem..
I think that's what probably caused the malfunction.
If anyone had a similar problem or has any info on this...your help is more than welcomed!!!
