### DevContainer on Ubuntu
|
||||
To use the DevContainer configuration on Ubuntu based systems two changes need to be made:
|
||||
|
||||
1. Modify the file ``.devcontainer/devcontainer.json`` and add the argument ``"--net=host"`` to the ``"runArgs"`` parameter making the line look like this:
|
||||
`` "runArgs": [ "--cap-add=SYS_PTRACE", "--security-opt", "seccomp=unconfined", "--net=host"],
|
||||
``
|
||||
2. Modify the file ``.vscode/launch.json`` and change the argument of ``"gdbTarget"`` to ``"127.0.0.1:3333"``, making the line look like:
|
||||
``"gdbTarget": "127.0.0.1:3333",``
|
||||
3. To start debugging launch openocd on your host system with the appropriate configuration, for example with a stlink-v2 the command is:
|
||||
``openocd -f interface/stlink.cfg -f target/nrf52.cfg``. This launches openocd with the default ports ``3333``, ``4444`` and ``6666``.
|
||||
4. In VsCode go to the Debug pane on the left of the screen and select the configuration ``Debug - Openocd docker Remote`` and hit the play button on the left.
