How to attach a running device(stm32) using segger Jlink?

[leewez]

Hi all,

I  can  build & download & debug the stm32 device by following the guild on the website.

But there is a chance that I need to debug some devices which was was already running , I need to get some context info to debug issues.

How can I do that?

The exact answer depends on the debug method you are using. Generally each method provides a setting that allows selecting whether you want to program the firmware or assume it’s already programmed.

If you are not sure, let us know which debug method you are using so that we could help you locate the settings.

Hi Bazis,

thanks very much for your reply.

the debug method I use is “Segger j-link”.  Would you please tell me how to attach device using this debug method?

Hi,

Currently this is a bit not straight-forward with Segger. Please edit the %LOCALAPPDATA%\VisualGDB\EmbeddedDebugPackages\com.sysprogs.arm.segger-dmsp\edp.xml file by removing the “load” command from GDBStartupCommands. We will add a configurable option to disable it in one of the next releases of the debugger package.
