Install Vscode extensions for debug

Once the install has completed, install the extensions needed to debug a Raspberry Pi Pico:

$ code --install-extension marus25.cortex-debug
$ code --install-extension ms-vscode.cmake-tools
$ code --install-extension ms-vscode.cpptools

Export Pi Pico SDK

Finally, start Visual Studio Code from a Terminal window:

$ export PICO_SDK_PATH=/home/pi/pico/pico-sdk
$ code

Add Vscode settings.

The pico-examples repo contains an example debug configuration that will start OpenOCD, attach GDB, and finally launch the application CMake is configured to build. Go ahead and copy this file (launch-raspberrypi-swd.json) into the picoexamples/.vscode directory as launch.json. We also provide a settings.json file that we recommend you also copy. This settings.json removes some potentially confusing options from the CMake plugin (including broken Debug and Run buttons that attempt to run a Pico binary on the host).

$ cd ~/pico/pico-examples
$ mkdir .vscode
$ cp ide/vscode/launch-raspberrypi-swd.json .vscode/launch.json
$ cp ide/vscode/settings.json .vscode/settings.json

Note:

You may have to amend the gdbPath in launch.json if your gdb is called arm-none-eabi-gdb instead of gdb-multiarch. PLEASE NOTE: Launch the debugger from the Debug Launcher and NOT from the Cmake build tools.

Tip:

If you switch to the "Terminal" tab in the bottom right-hand pane, you can use this to open minicom inside VSCode to see the UART output from the "Hello USB" example by typing,

$ minicom -b 115200 -o -D /dev/cu.usbmodem143202
