OLIMEX AVR-JTAG-USB and AT90CAN128 - Debugging Problems

Development Boards MicroMod

Hi,

I think I have a very special problem. I got an OLIMEX AVR-JTAG-USB to debug my AT90CAN128.

Programming the device via the JTAG interface works using AVR Studion (4.17) from my Windows PC and using my LINUX-System with avrdude too.

The problem shows when starting a debug session.

AVR Studio on Windows says:

Could not connect to JTAG ICE on COM2

LINUX-System fails after starting avarice and avr-gdb with the following messages in avarice:

Waiting for connection on port 10000.
Connection opened by host 127.0.0.1, port 44471.

response: 9D 00 41
Timed Out (partial response)
JTAG ICE communication failed

Can anybody help me solving this Problem or give me a hint where to search for a solution?

Thanks!!

I’m having exactly the same problem, AVR Studio 4.17 and FTDI VSP driver 2.6.00.

(It used to work OK in AVR Studio 4.16 and with earlier port drivers, but I have upgraded my C: disk since I last had it working)

Any news on how to solve this problem ?
