Thinking about it more, perhaps this is really the right place to begin this topic. BEGIN ORIGINAL POST Hi all, I did a search on the forum archives and couldn't find another instance of this problem. If I missed something, please let me know. I'm using Open On-Chip Debugger 0.1.0 (2009-03-04-15:47) Release on Ubuntu 8.10 Host Linux 2.6.27-14-generic #1 SMP Fri Mar 13 19:54:51 UTC 2009 x86_64 GNU/Linux with AT91SAM7x256 with an Olimex ARM-USB-OCD JTAG. When I set a breakpoint in some initialization code (early during startup) with arm-elf-gdb, GDB properly stops the board when it hits the breakpoint. However, when I try to step or next or anything, I get this from arm-elf-gdb: Watchdog has expired. Target detached. Nothing appears in the openocd log file. Here is a backtrace on openocd for one such event. Starting program: /usr/local/bin/openocd -s . -s ../../build -s ../../build/conf --log_output openocd.log Open On-Chip Debugger 0.1.0 (2009-03-04-15:47) Release BUGS?

This crash kills openocd every time. Any ideas?
