Hello,
at the moment I'm trying to get my Olimex LPC-E2294-8MB Board running
with OpenOCD and GDB. Unfortunalty I had only very little success. I've
compiled the current OpenOCD version from GIT with FTDI drivers.
Everything worked well for the first time I start debugging with GDB
(Version 6.8 and Version 7.0). But in a non-deterministic manner I get
problems with stopping at breakpoints when starting the debug session
and after pressing halt or stop I see that the debugger is halting in
the data-abort handler. The strange behavior is, that the same code runs
very well the first time and without any recompiling or code
modification the debugger doenst work right and stops in data-abort
handler. sometimes, after 5-8 trys it works again. But restarting the
hardware and restarting openocd doenst change it. If I connect with
telnet to openOCD it seems that every thing is working well. Checking PC
and Stepping works and my code does not hang is the data-abort handler.
I would assume, the the code works well an no illegal memory reagion is
accessed. After googling around the web I found this mailinglist thread
form Michael Fischer
http://lists.berlios.de/pipermail/openocd-development/2008-May/002068.html
talking about a similar problem with LPC and GDB. But I'm not sure
whether this could be the same or similar problem because the thread is
from 2008 an OpenOCD has been developed further.
If some can give me some hints about this I would be very happy....I
don't know what do to anymore.
Thanks
Beste regards
Andy
