Summary: No configuration available for device ID: ffff

Initial Comment:
I use avarice 2.6 on Linux 2.6.24-gentoo-r2.
I have a JTAGICEmkII and ATmega64. In Windows and AvrStudio4 I can upload and download flash/eep and etc. (Fuse bit JTAGEN = 1).
But in avarice I have:

$ avarice -2 -jusb                                                               

JTAG config starting.
Found a device: JTAGICEmkII
Serial number:  00:b0:00:00:37:2d
Reported JTAG device ID: 0xFFFF
No configuration available for device ID: ffff

In debug mode I see:
Automatic device detection:
response: 81 FF FF FF FF
JTAG id = 0xFFFFFFFF : Ver = 0xf : Device = 0xffff : Manuf = 0x7ff
No configuration available for device ID: ffff
(see attach file).

If I try to set -P atmega64 in command line, avarice say:
Reported JTAG device ID: 0xFFFF
Configured for device ID: 0x9602 atmega64 -- FORCED with atmega64
JTAG config complete.
JTAG ICE: Cannot synchronise

Thank you.

That part of the protocol is supposed to work completely without
OCDEN being turned on -- it would also be required to work in order
for using JTAG just for memory uploads which doesn't need OCDEN
(just JTAGEN).

Further, AVaRICE is able to temporarily enable OCDEN during just one
debuggin session (i.e. the previous state will be restored on exit).

Cannot be reproduced at all.

Probleme resolved by setting OCDEN fuse bit in AvrStudio4 on Windows.
