Error when trying to launch the debug session in VSC

[Mike Austin (LPI)]

I'm currently playing around with learning how to code in VCS with nRF Connect.  I was watching a series of Youtube instructional videos (https://www.youtube.com/watch?v=MGsZJpdLtco&list=PLx_tBuQ_KSqEt7NK-H7Lu78lT2OijwIMl&index=5) on debugging, but when I attempt to go through this process, things bomb out when I select the Debug option.

An error window pops up with this:

If I chose the "Open "launch.json"" option, this is what the file contains:

{

    // Use IntelliSense to learn about possible attributes.

    // Hover to view descriptions of existing attributes.

    // For more information, visit: go.microsoft.com/.../

    "version": "0.2.0",

    "configurations": [

        {

            "type": "nrf-connect",

            "request": "launch",

            "name": "Launch active build configuration",

            "config": "${activeConfig}",

            "runToEntryPoint": "main",

            "preLaunchTask": "nRF Connect: Build active configuration"

        },

        {

            "name": "Launch build",

            "type": "nrf-connect",

            "request": "launch",

            "config": "c:\\Nordic\\PrototypeSoftware\\myfirstapp\\build",

            "runToEntryPoint": "main"

        }

    ]

}

Any ideas what might be causing this issue?

I'm a bit of a novice with Nordic/nRF Connect so go easy on me with the techno-babble!!

Cheers,

Hi Mike,

I have seen other reports of this where specifying the cortex-debug.JLinkGDBServerPath in your VS Code settings fixed the issue, even though it should not be needed. That would be something like:

"cortex-debug.JLinkGDBServerPath": "C:\\path\\to\\JLinkGDBServerCL.exe"

Can you try this?

Hi Einar,

I think I've edited the right thing.  This is what my .vscode/settings.json file looks like:

{

  "nrf-connect.topdir": "c:\\Nordic\\v1.7.0",

  "nrf-connect.toolchain.path": "c:\\Nordic\\v1.7.0\\toolchain",

  "nrf-connect.applications": [

    "c:\\Nordic\\PrototypeSoftware\\myfirstapp",

    "c:\\Nordic\\PrototypeSoftware\\mysecondapp",

   

  ],

  "C_Cpp.default.configurationProvider": "nrf-connect",

  "cortex-debug.JLinkGDBServerPath": "C:\\path\\to\\JLinkGDBServerCL.exe"

}

But its not fixed the problem.

Any further ideas?

Cheers,

Mike

Hi,

You need to update the path here:

"cortex-debug.JLinkGDBServerPath": "C:\\path\\to\\JLinkGDBServerCL.exe"

This should point to wherever JLinkGDBServerCL.exe is located on your computer.

Hi Einar,

OK, tried that.  Updated that line to:

 "cortex-debug.JLinkGDBServerPath": "C:\\Program Files\\SEGGER\\JLink\\JLinkGDBServerCL.exe"

But I'm still getting the error. :-(

OK, managed to get Leo from Nordic in Sydney to sort me out.

Turns out I needed to add the path to the SEGGER JLink folder in the Environment Variables within WIndows (see below).

Debugging is now working :-)
