How to Attach the Debugger

leifzars — Thu, 19 Mar 2015 18:29:36 GMT

I have a running board that I want to attach the debugger to. In CW this was an option, but I don't see it in KDS.

Is this possible via KDS? If not will it be and when?

I am using a GDB SEGGER J-Link session type.

Thanks

Hello Leif,

You can do it following next steps:

Top menu Run->Debug configurations->GDB Segger J-Link Debugging

Best regards,

Alexey.

No I mean attach to an running device, not re downloading and then attaching as you normally do when you start a debugging session.

CW has the option to Download, Connect, Attach and Custom when starting a debugging session.

Hi Leif,

from my understanding, KDS doesn't have exact feature as CW,

CW uses a proprietary debugger engine while KDS uses gdb, that's different.

with KDS, we can use C/C++ Attach to Application feature:

Have a great day,

Hi Leif,

you can specify that it shall load only the symbols, but not flash the application file:

However, the Segger GDB still does a reset of the target at connection time: so it is not a true connect/attach, as the device receives a reset.

I hope this helps,

Erich
