Configure debugger with VSCode

Hi, I’m trying to configure debugger using Openocd 0.10.0 with VSCode from this reference on Windows 10. I can run Openocd and arm-none-eabi-gdb manually with exact configuration without any problem but on VS Code it seems that gdb debugger doesn’t run at all and only the debugger server runs. Here is launch.json that generated with mbed export.

                ]
            }
        }

}

And tasks.json

And here is the output log on debugger:

@masoudr This repo or the mbed-os repo are probably was the correct location for this particular issue.

My comment was in regard to your earlier statement

I think the documentation should be fixed for this. It didn’t say anything about serverStarted command for OpenOCD.

[janjongboom]

@masoudr See https://gist.github.com/janjongboom/51f2edbee8c965741465fa5feefe4cf1 - the serverStarted command needs to be different for OpenOCD and the serverArgs need to have the full path I believe.
