Remote debugging

[FreeRTOS.org]

Hi,

I am looking for information on how to set up and configure CB for remote debugging.  I can find information on configuring the IDE to use different compilers, but not different debug links.  For example, if I want to use OpenOCD to interface between the host computer and an ARM7 or Cortex M3, what would I have to do?  I expect directing GDB commands to the correct server is a case of just using the right GDB command line and init files.  Is this the case?  What about displaying registers, etc?  Do I have to define the architecture somehow so CB knows how to display the info received from GDB, or would I have to write new display windows in C/C++?

Sorry if this is all rather basic.  I would be grateful for any links or information that would provide a bit of info for me.

Regards,
Richard (http://www.FreeRTOS.org)

Hi Richard,

I do not know when an OpenOCD plug-in will be available, but perhaps these threads could be of interest.

Thanks for the links - it looks like others are also working on this.  I will keep an eye on the forum to see the latest developments.  Code::Blocks + FreeRTOS + OpenOCD could make a very nice setup.

Regards,

Hi Richard,

Enjoyed your Microchip training recently.

At the moment I am just about to release a plugin that will automatically launch OpenOCD within CodeBlocks.
But for now, you can run OpenOCD standalone with a script. The script contains the important info such as the GDB port.

You then go to the debugger/options tab (right click your project, debugger tab). In the remote connections tab, you can specify a port to match whatever port was selected in the OpenOCD script.

You will most likely specify extra init commands such as "b main", to breakpoint at main etc...

Then: Run OpenOCD (from a script or command line for instance).
CB: Click debug, then it should connect.

The biggest problem you will have (without modification of CB) is halting a running process:
