Ubuntu VSC OpenOCD debug and SWD flash configured as Windows by default

[bartola-valves]

I have a dual boot machine with Windows and Ubuntu.
Under Windows (Win 11 pro), I can successfully configure, debug and flash via SWD into a Pico and a Pico2.

Now, under Ubuntu, I can't make it work out of the box despite following all the instructions. I can only get the debug functionality working for the Pico Debug (Cortex Debug with external OpenOCD) only and if I modify the Flash Task.JSON I can get to work the Flash over SWD.

When I look at the tasks.json or the launch.json files when building an out of the box standard Hello Word program, I can see that all the configuration is by default as a Windows machine, not for OpenOCD in a Linux environment

launch.json
tasks.json

Attached are the examples files.

Below is the output of the terminal when executing the SWD flash:

Is there any specific way of installing the extension under Ubuntu to get recognised as a Linux environment and get the debug and SWD capability to work out of the box like in Windows?

Thank you

It looks like the issue is on Ubuntu it can’t find your debug probe - have you set up appropriate udev rules for it to work, as you would for other USB devices on Linux? The extension works out of the box on Rasberry Pi OS, which has the correct udev rules installed, so it does work on Linux environments.
