1. try to reproduce this using the dummy driver
I tried to use it as described here:
http://www.mail-archive.com/openocd-development@lists.berlios.de/msg06815.html
but I can't issue the continue command when connecting with gdb.
When I tried the dummy driver it gave errors:
$ ~/src/openocd-0.2.0/src/openocd -f dummy.cfg -f
openocd-0.2.0_at91sam7_gdb.cfg
$URL:
http://svn.berlios.de/svnroot/repos/openocd/tags/openocd-0.2.0/src/openocd.c
$
For bug reports, read http://svn.berlios.de/svnroot/repos/openocd/trunk/BUGS
Warn : Interface already configured, ignoring
Unknown command: ft2232_device_desc {Amontec JTAGkey}
So I commented the interface section in my configuration file; however
it seems there's something wrong with my configuration. Command line was:
$ ~/src/openocd-0.2.0/src/openocd -f dummy.cfg -f
openocd-0.2.0_at91sam7_gdb.cfg
Log is:

2. see if you can get a stack trace:
In the attachment you will find both the output with -d 3 and the
backtrace, as well as my configuration file (the only one I'm using).
