Hi together! (First of all, I'm german, so please excuse me, if I use some 'strange' words, that don't fit properly. But I think you'll understand, what i mean ;) )
Before I come to the problem, here are the conditions:
- STK500 Board
- JTAG ICE 3 Debugger (newest firmware)
- Windows 8.1
- Atmel Studio 6.2, just reinstalled to make sure, it's the latest version, also tried Atmel Studio 5.1
- Atmega32 (but the problem occurred with every other controller I tried: ATtiny2313, ATmega8515 and a few other Atmega32s)
Fuses: OCDEN  JTAGEN[X] SPIEN[X] CKOPT EESAVE SUT_CKSEL[Int Osc 8Mhz]
(already tried different fuse-settings concerning OCDEN and JTAGEN, none of them worked)
So here we go:
The problem is, that I can only use the ISP-Programming-Mode, no matter what frequencies I've set in the JTAG-Interface, nor which fuses I've set. I can set, reset the fuses and burn program via the ISP-Interface with no problems at all, but when I it comes to debugging my code (this is why I bought a debugger! ;) ), I get the following error-message:
"Failed to launch program. Error: No JTAG devices detected. Debugger command Activate physical failed"
I searched extensivly in all available threads in the internet concerning this topic, but I didn't find any other answers than "It works for me, you're doing something wrong!" "Got the same problem! Anybody got the solution?" and almost all of the threads were older than 2 years.
Most of the threads indicate a problem with Atmel Studio 6 and 6.1 and state, that the problem will be solved in version 6.1 or, in some rare entries, it'll be solved in version 6.2.
I still have the problem, and use version 6.2 and the newest firmare...
I hope you can help me...
Greetings from Germany!
