Print Page - Commands sent to debugger

Hello everyone.

I've recently started using Code::Blocks as my IDE for both C++ and C (for embedded systems), which I work on as a part of my university studies.

Currently I'm working with a micro-controller and have successfully gotten it hooked up to GDB (CodeSourcery arm-none-eabi) via. OpenOCD and through the C::B IDE.
I have one little problem though: When I launch the debugger, it seems to be sending the continue command "by itself". I find that rather annoying as I would like to keep my uC in a halted state. I "halt" the uC when OpenOCD receives an incoming GDB connection (specified in the OpenOCD configuration).

Is this intended behaviour? And is there any way to avoid it? Forgive me if there is an easy answer; I could very well be missing something :)

I'm using the 7844 SVN C::B build on Ubuntu 11.10, OpenOCD 0.5.0 and GDB 7.2.50.20100908

Thanks for the time invested in this great IDE!

Hm, we've discussed such an issue in this topic: http://forums.codeblocks.org/index.php/topic,15947.0.html but it was for the windows version of codesourcery's gdb.
Can you paste the full log of the debugger? (using code tags)

Also can you try to compile vanilla gdb yourself, the target should arm-none-eabi?

Sure

This is what gdb puts out when I'm connection through the command line

Code

And here is the same from within code blocks (no extra gdb commands append in my project options, so I'm not sure where they come from)

I'll compile the latest gcc toolchain for ARM, but I probably won't have time before tomorrow or the day after tomorrow)

Have you tried to use the "do not run the debuggee" option in Settings -> Debugger -> GDB Debugger -> Your config?

Ah! I knew I had missed something. This was just what I was looking for, thanks!
