That's what I thought for three hours of resetting, rebooting and looking
for the problem everywhere but in the toolchain. I am sure of my report
because this is what I did after those three fruitless hours:
1 - Reinstall Windows XP SP3 (actually, overwrite the partition with a
snapshot taken at the second reboot of a Windows installation, which is the
same thing but a lot faster)
2 - Before installing anything, other than Firefox, install AVR Studio 4.19
and the Jungo USB drivers.
3 - Install AVR Toolchain 3.4.0.
4 - Perform four trials using two projects, one new and one known to be
problem-free, and two debug interfaces, an AVR Dragon and a JTAGICE Mk II.
AVR Studio crashes at Start Debug on all trials. Reboot the PC between
trials. On all trials, Connect To Debugger and Read Device Signature worked
fine. I used Update Firmware on the AVR Dragon.
5 - Uninstall AVR Toolchain 3.4.0.
6 - Install AVR Toolchain 3.3.1.
7 - All trials now enter debug successfully.
But it will be interesting to see what
is causing this failure. You could try
to get in touch with Atmel support.
I don't have the time to be interested right now. If my guess that Atmel
are dropping support for AVR Studio 4.x is correct, then they won't be very
motivated to figure this problem out.
