I got a brand new Dragon but unfortunately I can't get it to do JTAG.
The target hardware is a ATmega32-16PU mounted on my precious STK500 which has nothing connected to it besides power. The reset jumper is off. They are connected via the STK500 JTAG adapter and a cable of about 12 cm or 4".
I'm able to read the signature, flash a programm, verify it and even change the fuse bits. But what just doesn't want to grghlng work is JTAG. It stops the connection while writing "Loading event memory ...". All I get is those three errors:
AVR Dragon: Timed out while waiting for response from the emulator. Please check cables and emulator power.
Coordinator: Error when writing memory contents to the debug platform.
Coordinator: Error loading object file.
I can't find an object file in any of my AVR C programs. I use the latest update of AVR Studio and updated the Dragon Firmware several times. I also connected JTAG directly to PortC on the STK500 which lead to the same behavior. I've also tried several internal clock settings (1...8 MHz) Google, forum search and AVR Studio didn't help.
I'm pretty much at the end of my wisdom here. Can anybody help?
PS: I need JTAG to debug my first paid coding project outside university :) [/bragging]
